• django dynamically deduce SITE_ID according to the domain

  - by dcrodjer

  I am trying to develop a site which will render multiple customized sites according to the domain name (subdomain to be more precise). My all the domain names are redirected to the So for each site there will be a corresponding model which defines how the site should look (SITE - SITE_SETTINGS) What will be the best way to utilize the django sites framework to get the SITE_ID of the current site from the domain name instead of hard-coding it in the settings files (django sites documentation) and run database queries, render the views accordingly? If using multiple settings file is my only option can this (wsgi script handle domain name) be done? Update So finally, following lukes answer, what I will do is define a custom middleware which makes the views available with the important vars required according to the domain. And as far as sitemaps and comments is concerned, I will have to customize sitemaps app and a custom sites model on which the other models of sites will be based. And since the comments system is based on the hard-coded sitemap ID I can use it just as is on the models (models will already be filtered according to the site based on my sites framework) though the permalink feature will have to be customized. So a lot of customization. Please suggest if I am going wrong anywhere in this because I have to ensure that the features of the project are optimized. Thanks!

• A quick question on data returned by jquery.ajax() call (EDITED)

  - by recipriversexclusion

  EDIT: The original problem was due a stupid syntax mistake somewhere else, whicj I fixed. I have a new problem though, as described below I have the following jquery.ajax call: $.ajax({ type: 'GET', url: servicesUrl + "/" + ID + "/tasks", dataType: "xml", success : createTaskListTable }); The createTaskListTable function is defined as function createTaskListTable(taskListXml) { $(taskListXml).find("Task").each(function(){ alert("Found task") }); // each task } Problem is: this doesn't work, I get an error saying taskListXml is not defined. JQuery documentation states that the success functions gets passed three arguments, the first of which is the data. How can I pass the data returned by .ajax() to my function with a variable name of my own choosing. My problem now is that I'm getting the XML from a previous ajax call! How is this even possible? That previous function is defined as function convertServiceXmlDataToTable(xml), so they don't use the same variable name. Utterly confused. Is this some caching issue? If so, how can I clear the browser cache to get rid of the earlier XML? Thanks!

• Faster quadrature decoder loops with Python code

  - by Kelei

  I'm working with a BeagleBone Black and using Adafruit's IO Python library. Wrote a simple quadrature decoding function and it works perfectly fine when the motor runs at about 1800 RPM. But when the motor runs at higher speeds, the code starts missing some of the interrupts and the encoder counts start to accumulate errors. Do you guys have any suggestions as to how I can make the code more efficient or if there are functions which can cycle the interrupts at a higher frequency. Thanks, Kel Here's the code: # Define encoder count function def encodercount(term): global counts global Encoder_A global Encoder_A_old global Encoder_B global Encoder_B_old global error Encoder_A = GPIO.input('P8_7') # stores the value of the encoders at time of interrupt Encoder_B = GPIO.input('P8_8') if Encoder_A == Encoder_A_old and Encoder_B == Encoder_B_old: # this will be an error error += 1 print 'Error count is %s' %error elif (Encoder_A == 1 and Encoder_B_old == 0) or (Encoder_A == 0 and Encoder_B_old == 1): # this will be clockwise rotation counts += 1 print 'Encoder count is %s' %counts print 'AB is %s %s' % (Encoder_A, Encoder_B) elif (Encoder_A == 1 and Encoder_B_old == 1) or (Encoder_A == 0 and Encoder_B_old == 0): # this will be counter-clockwise rotation counts -= 1 print 'Encoder count is %s' %counts print 'AB is %s %s' % (Encoder_A, Encoder_B) else: #this will be an error as well error += 1 print 'Error count is %s' %error Encoder_A_old = Encoder_A # store the current encoder values as old values to be used as comparison in the next loop Encoder_B_old = Encoder_B # Initialize the interrupts - these trigger on the both the rising and falling GPIO.add_event_detect('P8_7', GPIO.BOTH, callback = encodercount) # Encoder A GPIO.add_event_detect('P8_8', GPIO.BOTH, callback = encodercount) # Encoder B # This is the part of the code which runs normally in the background while True: time.sleep(1)

• Spring Form: Submitting extra parameter on submit buttons

  - by theringostarrs

  Hi, I am working on a form with a bunch of selection criteria that will generate a report when the form is submitted. I also have a number of different reports that can be generated form this same criteria, and want the type of report to be selectable by using a tab system where each tab clicked on submits the form and generates the correct report. I was to do this by passing an extra parameter into the form to switch onto the right form type I am new to Spring, and from the guidance of an elder was told to use an input button for each tab with the following approximate syntax: <input type="submit" name="${form.selectionValues.tabSelection}" value="1" /> tabSelection form property of the SelectionValues object is not being set. I wasn't surprised ;) DIdn't think this would work. So I am wondering how can I can submit a post back from a button in Spring containing the form values plus an extra tabSelection parameter and value? How should I mark up this mechanism? Will I have to do anything to the form controller to register this extra parameter? The original markup I was using to build this page, was using HTML anchor tags instead of buttons for the tab links, which would be much better for the CSS, is there any way to trigger a full form submit using an anchor href? I know this will be a GET request instead of a POST, and not associated with the form.. so I dont expect this to work.. just trying to think of solutions! I would prefer to use the priginal markup, as the styles are there. Any help would be appreciated

• Linq to SQL - Failing to update

  - by Isaac

  Hello, I'm having some troubles with updating linq to sql entities. For some reason, I can update every single field of my item entity besides name. Here are two simple tests I wrote: [TestMethod] public void TestUpdateName( ) { using ( var context = new SimoneDataContext( ) ) { Item item = context.Items.First( ); if ( item != null ) { item.Name = "My New Name"; context.SubmitChanges( ); } } } [TestMethod] public void TestUpdateMPN( ) { using ( var context = new SimoneDataContext( ) ) { Item item = context.Items.First( ); if ( item != null ) { item.MPN = "My New MPN"; context.SubmitChanges( ); } } } Unfortunately, TestUpdateName() fails with the following error: System.Data.SqlClient.SqlException: Incorrect syntax near the keyword 'WHERE'.. And here's the outputted SQL: UPDATE [dbo].[Items] SET WHERE ([Id] = @p0) AND ([CategoryId] = @p1) AND ([MPN] = @p2) AND ([Height] = @p3) AND ([Width] = @p4) AND ([Weight] = @p5) AND ([Length] = @p6) AND ([AdministrativeCost] = @p7) -- @p0: Input Int (Size = 0; Prec = 0; Scale = 0) [1] -- @p1: Input Int (Size = 0; Prec = 0; Scale = 0) [1] -- @p2: Input VarChar (Size = 10; Prec = 0; Scale = 0) [My New MPN] -- @p3: Input Decimal (Size = 0; Prec = 5; Scale = 3) [30.000] -- @p4: Input Decimal (Size = 0; Prec = 5; Scale = 3) [10.000] -- @p5: Input Decimal (Size = 0; Prec = 5; Scale = 3) [40.000] -- @p6: Input Decimal (Size = 0; Prec = 5; Scale = 3) [30.000] -- @p7: Input Money (Size = 0; Prec = 19; Scale = 4) [350.0000] -- Context: SqlProvider(Sql2008) Model: AttributedMetaModel Build: 3.5.30729.4926 As you can see, no update is being generated (SET is empty ...) I have no clue why is this happening. And already in advance ... YES, the table Item has a PK (Id). Thank you in advance!

• C programming - How to print numbers with a decimal component using only loops?

  - by californiagrown

  I'm currently taking a basic intro to C programming class, and for our current assignment I am to write a program to convert the number of kilometers to miles using loops--no if-else, switch statements, or any other construct we haven't learned yet are allowed. So basically we can only use loops and some operators. The program will generate three identical tables (starting from 1 kilometer through the input value) for one number input using the while loop for the first set of calculations, the for loop for the second, and the do loop for the third. I've written the entire program, however I'm having a bit of a problem with getting it to recognize an input with a decimal component. Here is what I have for the while loop conversions: #include <stdio.h> #define KM_TO_MILE .62 main (void) { double km, mi, count; printf ("This program converts kilometers to miles.\n"); do { printf ("\nEnter a positive non-zero number"); printf (" of kilometers of the race: "); scanf ("%lf", &km); getchar(); }while (km <= 1); printf ("\n KILOMETERS MILES (while loop)\n"); printf (" ========== =====\n"); count = 1; while (count <= km) { mi = KM_TO_MILE * count; printf ("%8.3lf %14.3lf\n", count, mi); ++count; } getchar(); } The code reads in and converts integers fine, but because the increment only increases by 1 it won't print a number with a decimal component (e.g. 3.2, 22.6, etc.). Can someone point me in the right direction on this? I'd really appreciate any help! :)

• Durandal Google Maps not showing properly

  - by user1891037

  Trying to show Google Maps using the Durandal. I'm now simply working with Durandal HTML Starter Kit so the other modules and all engine works properly. The thing is when I added the Google Map it doesn't fit the div size (the big part of div is just grey). As I understand, the problem is causing because Google Maps added before page is completely loaded. But I can't figure out how can I hook on page load event. Here is the module code: define(['knockout', 'gmaps'], function (ko, gmaps) { return { displayName: 'Google Maps', myMap: ko.observable({ lat: ko.observable(32), lng: ko.observable(10)}), activate: function () { console.log('activate'); ko.bindingHandlers.map = { init: function (element, valueAccessor, allBindingsAccessor, viewModel) { console.log('init'); var mapObj = ko.utils.unwrapObservable(valueAccessor()); var latLng = new gmaps.LatLng( ko.utils.unwrapObservable(mapObj.lat), ko.utils.unwrapObservable(mapObj.lng)); var mapOptions = { center: latLng, zoom: 5, mapTypeId: gmaps.MapTypeId.ROADMAP}; mapObj.googleMap = new gmaps.Map(element, mapOptions); } } }, attached: function() { console.log('attached'); }, compositionComplete: function() { console.log('compositionComplete'); } }; }); And a very simple HTML code: <section> <div id="gmap-canvas" data-bind="map:myMap"></div> </section> I'm loading Google Maps with async plug-in in my shell.js. It works fine. Screenshot with trouble here - http://clip2net.com/s/ibswAa P.S. div size is defined in .CSS file. P.S. I tried to use getElementById approach provided here and it's work great if placed in compositionComplete block. But when I tried to move my bindings to this block nothing happens at all. Thanks!

• Query about running a program through valgrind and getting false results comparing to other systems.

  - by FILIaS

  Yesterday i posted this: What's the problem with this code? [hashtable in C] and paxdiablo offered to help me. He posted a sample of code and asked me to run it through valgrind on my machine. This code normally generates: 12,4 But on my machine, i get 24,8. The doubled! I'm just curious why is that happening. Hope sb has a good explaination. I post also paxdiablo's code (for anyone who cant find it.) #include <stdio.h> #include <stdlib.h> typedef struct HashTable { int size ; struct List *head; struct List *tail; } HashTable; typedef struct List { char *number; char *name; int time; struct List *next; } List; #define size_of_table 211 HashTable *createHashTable(void) { HashTable *new_table = malloc(sizeof(*new_table)*size_of_table); //line 606 printf ("%d\n", sizeof(*new_table)); printf ("%d\n", sizeof(new_table)); if (new_table == NULL) { return NULL; } int i=0; for(i; i<size_of_table; i++) { new_table[i].size=0; new_table[i].head=NULL; new_table[i].tail=NULL; } return new_table; } int main(void) { HashTable *x = createHashTable(); free (x); return 0; }

• C++ Initialize array in constructor EXC_BAD_ACCESS

  - by user890395

  I'm creating a simple constructor and initializing an array: // Construtor Cinema::Cinema(){ // Initalize reservations for(int i = 0; i < 18; i++){ for(int j = 0; j < 12; j++){ setReservation(i, j, 0); } } // Set default name setMovieName("N/A"); // Set default price setPrice(8); } The setReservation function: void Cinema::setReservation(int row, int column, int reservation){ this->reservations[row][column] = reservation; } The setMovieName function: void Cinema::setMovieName(std::string movieName){ this->movieName = movieName; } For some odd reason when I run the program, the setMovieName function gives the following error: "Program Received Signal: EXC_BAD_ACCESS" If I take out the for-loop that initializes the array of reservations, the problem goes away and the movie name is set without any problems. Any idea what I'm doing wrong? This is the Cinema.h file: #ifndef Cinema_h #define Cinema_h class Cinema{ private: int reservations[17][11]; std::string movieName; float price; public: // Construtor Cinema(); // getters/setters int getReservation(int row, int column); int getNumReservations(); std::string getMovieName(); float getPrice(); void setReservation(int row, int column, int reservation); void setMovieName(std::string movieName); void setPrice(float price); }; #endif

• Linking Apache to Tomcat with multiple domains.

  - by Royce Thigpen

  Okay, so I've been working for a while on this, and have been searching, but so far I have not found any answers that actually answer what I want to know. I'm a little bit at the end of my rope with this one, but I'm hoping I can figure this out sometime soon. So I have Apache 2 installed and serving up standard webpages, but I also have that linked to a Tomcat instance for one of my domains currently supported. However, I want to add another domain to the server via Apache that points to a separate code base from the one I already have. I have been coming at this from several different angles, and I have determined that I just don't know enough about setting up these servers to really do what I want to do. Little information on my server: Currently running a single Tomcat5.5 instance with Apache 2, using mod_jk to connect them together. I have a worker in workers.properties that points it's "host" field to "localhost" with the correct port my Tomcat instance, so that all works. In my Tomcat server.xml file, I have a host defined as "localhost" that points at my webapp that I am currently serving up, with that host set as the defaultHost as well. One thought I had was that I could add a new worker with a different host than "localhost" (i.e. host2) and then define a new host in my server.xml file called "host2" to match it, but after reading around some on the internet, It seems the "host" of the worker must point to a server, and not a hostname in the Tomcat instance, is this correct? Again, a simple rundown of what I want: Setup in apache/tomcat combo such that www.domain1.com points at "webapp1" and www.domain2.com points at "webapp2".

• What to pass parameters to start an workflow through WCF

  - by Rubens Farias

  It's possible to define some start values to an workflow using WorkflowInstance.CreateWorkflow, like this: using(WorkflowRuntime runtime = new WorkflowRuntime()) { Dictionary<string, object> parameters = new Dictionary<string, object>(); parameters.Add("First", "something"); parameters.Add("Second", 42); WorkflowInstance instance = runtime.CreateWorkflow(typeof(MyStateMachineWorkflow), parameters); instance.Start(); waitHandle.WaitOne(); } This way, a MyStateMachineWorkflow instance is created and First and Second public properties gets that dictionary values. But I'm using WCF; so far, I managed to create a Start method which accepts that two arguments and I set that required fields by using bind on my ReceiveActivity: using (WorkflowServiceHost host = new WorkflowServiceHost(typeof(MyStateMachineWorkflow))) { host.Open(); ChannelFactory<IMyStateMachineWorkflow> factory = new ChannelFactory<IMyStateMachineWorkflow>("MyStateMachineWorkflow"); IMyStateMachineWorkflow proxy = factory.CreateChannel(); // set this values through binding on my ReceiveActivity proxy.Start("something", 42); } While this works, that create an anomaly: that method should be called only and exactly once. How can I start an workflow instance through WCF passing those arguments? On my tests, I just actually interact with my workflow through wire after I call that proxy method. Is there other way?

• C callback functions defined in an unnamed namespace?

  - by Johannes Schaub - litb

  Hi all. I have a C++ project that uses a C bison parser. The C parser uses a struct of function pointers to call functions that create proper AST nodes when productions are reduced by bison: typedef void Node; struct Actions { Node *(*newIntLit)(int val); Node *(*newAsgnExpr)(Node *left, Node *right); /* ... */ }; Now, in the C++ part of the project, i fill those pointers class AstNode { /* ... */ }; class IntLit : public AstNode { /* ... */ }; extern "C" { Node *newIntLit(int val) { return (Node*)new IntLit(val); } /* ... */ } Actions createActions() { Actions a; a.newIntLit = &newIntLit; /* ... */ return a; } Now the only reason i put them within extern "C" is because i want them to have C calling conventions. But optimally, i would like their names still be mangled. They are never called by-name from C code, so name mangling isn't an issue. Having them mangled will avoid name conflicts, since some actions are called like error, and the C++ callback function has ugly names like the following just to avoid name clashes with other modules. extern "C" { void uglyNameError(char const *str) { /* ... */ } /* ... */ } a.error = &uglyNameError; I wondered whether it could be possible by merely giving the function type C linkage extern "C" void fty(char const *str); namespace { fty error; /* Declared! But i can i define it with that type!? */ } Any ideas? I'm looking for Standard-C++ solutions.

• jQuery selector for option tag value attribute returns null

  - by Ben

  Hello, I am trying to change the selected option in a select dropdown box with jQuery. I have it set so that it finds the hash tag at the end of the URL and based on that hash tag it changes the selected option in the select box. Most of my code is functional, it successfully finds the hash tag and executes the if statement that corresponds with it. However, when it goes to execute the "then" section of the statement when it goes to the selector for the option (which uses an attribute selector based on the value attribute of the option tag) it returns null. If figured this out with firebug, in the console it says that the selector is null. Here is my code: $(document).ready(function() { var $hash = window.location.hash if($hash == "#htmlcss") { $('option[value="HTML/CSS Coding"]').attr("selected","selected") } if($hash == "#php") { $('option[value="PHP Coding"]').attr("selected","selected") } if($hash == "#jscript") { $('option[value="Javascript and jQuery Coding"]').attr("selected","selected") } if($hash == "#improv") { $('option[value="General Website Improvements"]').attr("selected","selected") } if($hash == "#towp") { $('option[value="Website Conversion to Wordpress"]').attr("selected","selected") } if($hash == "#wptheme") { $('option[value="Wordpress Theme Design"]').attr("selected","selected") } if($hash == "#complete") { $('option[value="Complete Website Creation"]').attr("selected","selected") } if($hash == "#server") { $('option[value="Web Server Configuration"]').attr("selected","selected") } }); So to clarify, when I enter in a url that ends in the #php hash tag, for example, the desired action does not occur which would change the "PHP Coding" option to the selected one by using the "selected" html attribute however the selector for the particular option tag returns null. Is there a problem with my syntax or is my code not functioning in the way that I think it should? Thanks very much.

  i use the following method to send email to list of users i want the (To) in each email to be for just the user only not all users i.e appears to the users that the email is sent to only him my guess is to loop on: message.addRecipients(Message.RecipientType.TO, address); then send the message right? , but this is a heavy process sending an email many times any ideas ? suppose that i have the timezone for each user and i want to send each user the message in his timzone, the same issue i guess setting sent date for each user in his timezone then sending the message, right ? the method is: try { Properties props = System.getProperties(); props.put("mail.smtp.host", "localhost"); // Get a mail session Session session = Session.getDefaultInstance(props, null); // Define a new mail message Message message = new MimeMessage(session); InternetAddress ia = new InternetAddress(); ia.setPersonal("MySite"); ia.setAddress(from); message.setFrom(ia); Address[] address = new Address[recievers.size()]; for (int i = 0; i < recievers.size(); i++) { address[i] = new InternetAddress(recievers.get(i)); } message.addRecipients(Message.RecipientType.TO, address); message.setSubject(subject); // Create a message part to represent the body text BodyPart messageBodyPart = new MimeBodyPart(); messageBodyPart.setContent(body, "text/html"); // use a MimeMultipart as we need to handle the file attachments Multipart multipart = new MimeMultipart(); // add the message body to the mime message multipart.addBodyPart(messageBodyPart); // Put all message parts in the message message.setContent(multipart); message.setSentDate(getCurrentDate()); // Send the message Transport.send(message); } catch (Exception ex) {}

• Preprocessor "macro function" vs. function pointer - best practice?

  - by Dustin

  I recently started a small personal project (RGB value to BGR value conversion program) in C, and I realised that a function that converts from RGB to BGR can not only perform the conversion but also the inversion. Obviously that means I don't really need two functions rgb2bgr and bgr2rgb. However, does it matter whether I use a function pointer instead of a macro? For example: int rgb2bgr (const int rgb); /* * Should I do this because it allows the compiler to issue * appropriate error messages using the proper function name, * not to mention possible debugging benefits? */ int (*bgr2rgb) (const int bgr) = rgb2bgr; /* * Or should I do this since it is merely a convenience * and they're really the same function anyway? */ #define bgr2rgb(bgr) (rgb2bgr (bgr)) I'm not necessarily looking for a change in execution efficiency as it's more of a subjective question out of curiosity. I am well aware of the fact that type safety is neither lost nor gained using either method. Would the function pointer merely be a convenience or are there more practical benefits to be gained of which I am unaware?

• [C++][OpenMP] Proper use of "atomic directive" to lock STL container

  - by conradlee

  I have a large number of sets of integers, which I have, in turn, put into a vector of pointers. I need to be able to update these sets of integers in parallel without causing a race condition. More specifically. I am using OpenMP's "parallel for" construct. For dealing with shared resources, OpenMP offers a handy "atomic directive," which allows one to avoid a race condition on a specific piece of memory without using locks. It would be convenient if I could use the "atomic directive" to prevent simultaneous updating to my integer sets, however, I'm not sure whether this is possible. Basically, I want to know whether the following code could lead to a race condition vector< set<int>* > membershipDirectory(numSets, new set<int>); #pragma omp for schedule(guided,expandChunksize) for(int i=0; i<100; i++) { set<int>* sp = membershipDirectory[5]; #pragma omp atomic sp->insert(45); } (Apologies for any syntax errors in the code---I hope you get the point) I have seen a similar example of this for incrementing an integer, but I'm not sure whether it works when working with a pointer to a container as in my case.

• how to switch views according to command

  - by Veer

  I've a main view and many usercontrols. The main view contains a two column grid, with the first column filled with a listbox whose datatemplate consists of a usercontrol and the second column filled with another usercontrol. These two usercontrols have the same datacontext. MainView: <Grid> //Column defs ... <ListView Grid.Column="0" ItemSource="{Binding Foo}"> ... <DataTemplate> <Views: FooView1 /> </DataTemplate> </ListView> <TextBlock Text="{Binding Foo.Count}" /> <StackPanel Grid.Column="1"> <Views: FooView2 /> </StackPanel> <Grid> FooView1: <UserControl> <TextBlock Text="{Binding Foo.Title}"> </UserControl> FooView2: <UserControl> <TextBlock Text="{Binding Foo.Detail1}"> <TextBlock Text="{Binding Foo.Detail2}"> <TextBlock Text="{Binding Foo.Detail3}"> <TextBlock Text="{Binding Foo.Detail4}"> </UserControl> I've no IDE here. Excuse me if there is any syntax error When the user clicks on a button. These two usercontrols have to be replaced by another two usercontrols, so the datacontext changes, the main ui remaining the same. ie, FooView1 by BarView1 and FooView2 by BarView2 In short i want to bind this view changes in mainview to my command (command from Button) How can i do this? Also tell me if i could merge the usercontrol pairs, so that only one view exists for each viewmodel ie, FooView1 and FooView2 into FooView and so on...

• Dynamic evaluation of a table column within an insert before trigger

  - by Tim Garver

  HI All, I have 3 tables, main, types and linked. main has an id column and 32 type columns. types has id, type linked has id, main_id, type_id I want to create an insert before trigger on the main table. It needs to compare its 32 type columns to the values in the types table if the main table column has an 'X' for its value and insert the main_id and types_id into the linked table. i have done a lot of searching, and it looks like a prepared statement would be the way to go, but i wanted to ask the experts. The issue, is i dont want to write 32 IF statements, and even if i did, i need to query the types table to get the ID for that type, seems like a huge waist of resources. Ideally i want to do this inside of my trigger: BEGIN DECLARE @types results_set -- (not sure if this is a valid type); -- (iam sure my loop syntax is all wrong here)... SET @types = (select * from types) for i=0;i<types.records;i++ { IF NEW.[i.type] = 'X' THEN insert into linked (main_id,type_id) values (new.ID, i.id); END IF; } END; Anyway, This is what i was hoping to do, maybe there is a way to dynamically set the field name inside of a results loop, but i cant find a good example of this. Thanks in advance Tim

  Hi everyone, this time, I'm facing a really weird problem. I've the following code: $xml = simplexml_load_file($this->interception_file); foreach($xml->children() as $class) { $path = str_replace('__CLASS_DIR__',CLASS_DIR,$class['path']); if(!is_file($path)) { throw new Exception('Bad configuration: file '.$path.' not found'); } $className = pathinfo($path,PATHINFO_FILENAME); foreach($class as $method) { $method_name = $method['name']; $obj = new $className(); var_dump(in_array($method_name,get_class_methods($className)));exit; echo $obj->$method_name();### not a method ??? } } As you can see, I get the class name and method name from an XML file. I can create an instance of the class without any problem. The var_dump at the end returns true, that means $method_name (which has 2 optional parameters) is a method of $className. BUT, and I am pretty sure the syntax is correct, when I try: $obj-$method_name() I get: Fatal error: Method name must be a string If you have any ideas, pleaaaaase tell me :) Thanks in advance, Rolf

• SQL putting two single quotes around datetime fields and fails to insert record

  - by user82613

  I am trying to INSERT into an SQL database table, but it doesn't work. So I used the SQL server profiler to see how it was building the query; what it shows is the following: declare @p1 int set @p1=0 declare @p2 int set @p2=0 declare @p3 int set @p3=1 exec InsertProcedureName @ConsumerMovingDetailID=@p1 output, @UniqueID=@p2 output, @ServiceID=@p3 output, @ProjectID=N'0', @IPAddress=N'66.229.112.168', @FirstName=N'Mike', @LastName=N'P', @Email=N'[email protected]', @PhoneNumber=N'(254)637-1256', @MobilePhone=NULL, @CurrentAddress=N'', @FromZip=N'10005', @MoveInAddress=N'', @ToZip=N'33067', @MovingSize=N'1', @MovingDate=''2009-04-30 00:00:00:000'', /* Problem here ^^^ */ @IsMovingVehicle=0, @IsPackingRequired=0, @IncludeInSaveologyPlanner=1 select @p1, @p2, @p3 As you can see, it puts a double quote two pairs of single quotes around the datetime fields, so that it produces a syntax error in SQL. I wonder if there is anything I must configure somewhere? Any help would be appreciated. Here is the environment details: Visual Studio 2008 .NET 3.5 MS SQL Server 2005 Here is the .NET code I'm using.... //call procedure for results strStoredProcedureName = "usp_SMMoverSearchResult_SELECT"; Database database = DatabaseFactory.CreateDatabase(); DbCommand dbCommand = database.GetStoredProcCommand(strStoredProcedureName); dbCommand.CommandTimeout = DataHelper.CONNECTION_TIMEOUT; database.AddInParameter(dbCommand, "@MovingDetailID", DbType.String, objPropConsumer.ConsumerMovingDetailID); database.AddInParameter(dbCommand, "@FromZip", DbType.String, objPropConsumer.FromZipCode); database.AddInParameter(dbCommand, "@ToZip", DbType.String, objPropConsumer.ToZipCode); database.AddInParameter(dbCommand, "@MovingDate", DbType.DateTime, objPropConsumer.MoveDate); database.AddInParameter(dbCommand, "@PLServiceID", DbType.Int32, objPropConsumer.ServiceID); database.AddInParameter(dbCommand, "@FromAreaCode", DbType.String, pFromAreaCode); database.AddInParameter(dbCommand, "@FromState", DbType.String, pFromState); database.AddInParameter(dbCommand, "@ToAreaCode", DbType.String, pToAreaCode); database.AddInParameter(dbCommand, "@ToState", DbType.String, pToState); DataSet dstSearchResult = new DataSet("MoverSearchResult"); database.LoadDataSet(dbCommand, dstSearchResult, new string[] { "MoverSearchResult" });

• Sending one record from cursor to another function Postgres

  - by PylonsN00b

  FYI: I am completely new to using cursors... So I have one function that is a cursor: CREATE FUNCTION get_all_product_promos(refcursor, cursor_object_id integer) RETURNS refcursor AS ' BEGIN OPEN $1 FOR SELECT * FROM promos prom1 JOIN promo_objects ON (prom1.promo_id = promo_objects.promotion_id) WHERE prom1.active = true AND now() BETWEEN prom1.start_date AND prom1.end_date AND promo_objects.object_id = cursor_object_id UNION SELECT prom2.promo_id FROM promos prom2 JOIN promo_buy_objects ON (prom2.promo_id = promo_buy_objects.promo_id) LEFT JOIN promo_get_objects ON prom2.promo_id = promo_get_objects.promo_id WHERE (prom2.buy_quantity IS NOT NULL OR prom2.buy_quantity > 0) AND prom2.active = true AND now() BETWEEN prom2.start_date AND prom2.end_date AND promo_buy_objects.object_id = cursor_object_id; RETURN $1; END; ' LANGUAGE plpgsql; SO then in another function I call it and need to process it: ... --Get the promotions from the cursor SELECT get_all_product_promos('promo_cursor', this_object_id) updated := FALSE; IF FOUND THEN --Then loop through your results LOOP FETCH promo_cursor into this_promotion --Preform comparison logic -this is necessary as this logic is used in other contexts from other functions SELECT * INTO best_promo_results FROM get_best_product_promos(this_promotion, this_object_id, get_free_promotion, get_free_promotion_value, current_promotion_value, current_promotion); ... SO the idea here is to select from the cursor, loop using fetch (next is assumed correct?) and put the record fetched into this_promotion. Then send the record in this_promotion to another function. I can't figure out what to declare the type of this_promotion in get_best_product_promos. Here is what I have: CREATE OR REPLACE FUNCTION get_best_product_promos(this_promotion record, this_object_id integer, get_free_promotion integer, get_free_promotion_value numeric(10,2), current_promotion_value numeric(10,2), current_promotion integer) RETURNS... It tells me: ERROR: plpgsql functions cannot take type record OK first I tried: CREATE OR REPLACE FUNCTION get_best_product_promos(this_promotion get_all_product_promos, this_object_id integer, get_free_promotion integer, get_free_promotion_value numeric(10,2), current_promotion_value numeric(10,2), current_promotion integer) RETURNS... Because I saw some syntax in the Postgres docs showed a function being created w/ a input parameter that had a type 'tablename' this works, but it has to be a tablename not a function :( I know I am so close, I was told to use cursors to pass records around. So I studied up. Please help.

• pulling a value from NSMutableDictionary

  - by Jared Gross

  I have a dictionary array with a key:@"titleLabel". I am trying to load a pickerView with ONE instance of each @"titleLabel" key so that if there are multiple objects with the same @"titleLabel" only one title will be displayed. I've done some research on this forum and looked at apples docs but haven't been able to put the puzzle together. Below is my code but I am having trouble pulling the values. Right now when I run this code it throws an error Incompatible pointer types sending 'PFObject *' to parameter of type 'NSString' which i understand but am just not sure how to remedy. Cheers! else { // found messages! self.objectsArray = objects; NSMutableDictionary *dict = [[NSMutableDictionary alloc] init]; for(id obj in self.objectsArray){ PFObject *key = [self.objectsArray valueForKey:@"titleLabel"]; if(![dict objectForKey:@"titleLabel"]){ [dict setValue:obj forKey:key]; } } for (id key in dict) { NSLog(@"Objects array is %d", [self.objectsArray count]); NSLog(@"key: %@, value: %@ \n", key, [dict objectForKey:key]); } [self.pickerView reloadComponent:0]; } }];` Here is where I define the PFObject and keys: PFObject *image = [PFObject objectWithClassName:@"Images"]; [image setObject:file forKey:@"file"]; [image setObject:fileType forKey:@"fileType"]; [image setObject:title forKey:@"titleLabel"]; [image setObject:self.recipients forKey:@"recipientIds"]; [image setObject:[[PFUser currentUser] objectId] forKey:@"senderId"]; [image setObject:[[PFUser currentUser] username] forKey:@"senderName"]; [image saveInBackground];

• can I add properties to a typo3 extbase domain model object?

  - by The Newbie Qs

  I want to store a username in a coupon object, each coupon object already has the uid of the user who created it. I can loop over the coupon objects and read the associated usernames from fe_users but how then will I save those usernames into the coupons so when they are passed to the template the usernames can be read like so coupon.username, or in some other easy way so each username will appear on the page with the right coupon as they are all printed out in a table? If I was doing basic php instead of typo3 i would just define a query but what is the typo3 v4.5 way? My code so far - which dies on the line where I try to assign the new property --creatorname -- to the $coup object. public function listAction() { $coupons = $this->couponRepository->findAll(); // @var Tx_Extbase_Domain_Repository_FrontendUserRepository $userRepository */ $userRepository = $this->objectManager->get("Tx_Extbase_Domain_Repository_FrontendUserRepository"); foreach ($coupons as $coup) { echo '<br />test '.$coup->getCreator(); echo '<br />count = '.$userRepository->countAll().'<br />'; $newObject = $userRepository->findByUid( intval($coup->getCreator())); //var_dump($newObject); var_dump($coup); echo '<br />getUsername '.$newObject->getUsername() ; $coup['creatorname'] = $newObject->getUsername(); echo '<br />creatorname '.$coup['creatorname'] ; } $this->view->assign('coupons', $coupons); }
