  • Help with create action in a different show page

    - by Andrew
    Hi, I'm a Rails newbie and want to do something but keep messing something up. I'd love some help. I have a simple app that has three tables. Users, Robots, and Recipients. Robots belong_to users and Recipients belong_to robots. On the robot show page, I want to be able to create recipients for that robot right within the robot show page. I have the following code in the robot show page which lists current recipients: <table> <% @robot.recipients.each do |recipient| %> <tr> <td><b><%=h recipient.chat_screen_name %></b> via <%=h recipient.protocol_name</td> <td><%= link_to 'Edit', edit_recipient_path(recipient) %>&nbsp;</td> <td><%= link_to 'Delete', recipient, :confirm => 'Are you sure?', :method => :delete %></td> </tr> <% end %> </table> What I'd like to do is have an empty field in which the user can add a new recipient, and have tried the following: I added this to the Robots Show view: <% form_for(@robot.recipient) do |f| %> Enter the screen name<br> <%= f.text_field :chat_screen_name %> <p> <%= f.submit 'Update' %> </p> <% end %> and then this to the Robot controller in the show action: @recipient = Recipient.new @recipients = Recipient.all Alas, I'm still getting a NoMethod error that says: "undefined method `recipient' for #" I'm not sure what I'm missing. Any help would be greatly appreciated. Thank you.

  • Large Video Uploads via a website

    - by Andrew
    Some of the problems that can happen are timeouts, disconnections, and not being able to resume a file and having to start from the beginning. Assuming these files are up to around 5gigs in size, what is the best solution for dealing with this problem? I'm using a Drupal 6 install for the website. Some of my constraints due to the server setup I have to deal with: Shared hosting with max 200 connections at a time (unlimited disk space) Shared hosting. Unable to create users through an API (so can't automatically generate ftp accounts) I do have the ability to run cron-type scripts via a Drupal module. My initial thought was to create ftp users based off of Drupal accounts and requiring them to download an ftp client for their OS of choice. But the lack of API to auto-create ftp accounts and the inability to do it from command line kind of hinder that solution. If there's a workaround someone can think of, let me know! Thanks

  • jQuery doesn't fire some events while I'm not logged in (Joomla)

    - by Andrew Sekaev
    So basically, .resize function fails until I log in. What does that mean? And how that can be fixed? Almost all other functions work fine. The site is still in developement, so no live version sadly. UPDATE: jQuery(window).resize(function() { var windowSize = jQuery(window).width() var windowWidth = (jQuery(window).width()-60)/6; var windowHeight = windowWidth/1.6; /*grid resize*/ jQuery('.xc-block').css({'width':windowWidth, 'height':windowHeight}); }); This is very simple script, cant really tell what can be wrong... Any thoughts guys? P.S:also no errors in FireBug...

  • Reporting. MS Word templates population required

    - by Andrew Florko
    Application we developed fills MS Word templates with data from Database. Customers require to have ability edit Word templates via MS Word (change style, font, layout e.t.c) with no additional software to be installed and no training. AFAIK, Sql Reporting Services and Crystal Reports can't populate MS Word templates produced in MS Word. So we implemented our custom solution that maps .net classes onto xml-saved MS Word documents. It looks like we declare class MyTemplate { // maps to [age] field declared in ms document straight in the text int Age { get; set; } // maps to table by attributes applied to property (omitted) List<Person> Persons { get; set; } } We also implemented images insertion. Are there any free libraries for this task or may be you use your own MS-word templators in your projects?

  • MySQL join headaches, please help!

    - by Andrew Heath
    Ok, I've hit the wall here and need some help. Sample tables are as follows: SCENARIO_NATIONS [scenID] [side] [nation] scen001 1 Germany scen001 2 Britain scen001 2 Canada SCENARIO_NEEDUNITS [scenID] [unitID] scen001 0001 scen001 0003 scen001 0107 scen001 0258 scen001 0759 UNIT_BASIC_DATA [unitID] [nation] [name] 0001 Germany Mortars 0003 Germany Infantry 0107 Britain Lt 0258 Britain Infantry 0759 Canada Kilted Yaksmen Goal: given a scenID, pull a list of units from the database sorted by side, nation, name. I can do everything except for the side inclusion with: SELECT scenario_needunits.scenID, unit_basic_data.nation, unit_basic_data.name FROM scenario_needunits LEFT OUTER JOIN unit_basic_data ON scenario_needunits.unitID=unit_basic_data.unitID WHERE scenario_needunits.scenID='scen001' ORDER BY unit_basic_data.nation ASC, unit_basic_data.name ASC I've tried just dropping the SCENARIO_NATIONS table in as a LEFT OUTER JOIN on scenID but what ends up happening is that ALL units come back with a side of 1 because that's always the first side listed for the scenID in the SCENARIO_NATIONS table. Conceptually, what I think needs to happen is SCENARIO_NATIONS must be joined to both the scenID (to restrict it to just that scenario) and to each unit's nation but I don't have any idea how to do that and my Google-fu is inadequate. :-/

  • C#: Populating a UI using separate threads.

    - by Andrew
    I'm trying to make some sense out of an application Ive been handed in order to track down the source of an error. Theres a bit of code (simplified here) which creates four threads which in turn populate list views on the main form. Each method gets data from the database and retrieves graphics from a resource dll in order to directly populate an imagelist and listview. From what Ive read on here (link) updating UI elements from any thread other than the UI thread should not be done, and yet this appears to work? Thread t0 = new Thread(new ThreadStart(PopulateListView1)); t0.IsBackground = true; t0.Start(); Thread t1 = new Thread(new ThreadStart(PopulateListView2)); t1.Start(); Thread t2 = new Thread(new ThreadStart(PopulateListView3)); t2.Start(); Thread t3 = new Thread(new ThreadStart(PopulateListView4)); t3.Start(); The error itself is a System.InvalidOperationException "Image cannot be added to the ImageList." which has me wondering if the above code is linked in some way. Iis this method of populating the UI recommended and if not what are the possible complications resulting from it?

  • Can JAXB store the class name in the XML so that the the deserialize code doesn't need knowledge of the class?

    - by Andrew
    It seems the standard approach for deserializing JAXB XML is to specify the package name when creating the context. Then, JAXB looks up the class based on the root element: JAXBContext jc = JAXBContext.newInstance("com.foo"); Unmarshaller u = jc.createUnmarshaller(); Object o = u.unmarshal(new StringReader("...")); I'm looking for a more flexible approach where I don't have to specify the package name and could still deserialize any object. This would be as simple as JAXB storing the package in the XML, but I can't seem to find out how to do this. I can write the code to do it myself but that would be unpleasant. It would like JAXB to do it, if possible. BTW, I am not using schemas, just Annotations and marshal/unmarshal. Any ideas?

  • Why is my web page left-aligned on iPad?

    - by Andrew
    I recently built a site and centered it using margin: 0 auto. I also wrapped elements in a .wrapper class with a width set to 960px and then had the parent element extend across the whole browser. When I view the Brands screen on an iPad though, the site is left-aligned and does not extend across the whole window. Any thoughts to why this might be happening, and how to correct it? See below for a screenshot:

  • Can I cache a ManyToOne hibernate object without it being lazy loaded?

    - by Andrew
    @ManyToOne @JoinColumn(name = "play_template_id", table = "team_play_mapping" ) public Play getPlay() { return play; } public void setPlay( Play play ) { this.play = play; } By default, this is eager loading. Can I get it so that it will read the play object from a cache without making it lazy loading? Am I correct that eager loading will force it to do a join query and hence no caching?

  • MVP pattern. Presenter requires new view instance. Best practice

    - by Andrew Florko
    I try to apply MVP pattern for win.forms application. I have 2 forms: main & child. Main has a button and when you click it - child form should appear. There are 2 views interfaces that forms implement IMainView { event OnClick; ... } IChildView { ... } There are two presenters MainPresenter(IMainView) & ChildPresenter(IChildView) MainPresenter listens to OnClick event and then should create IChildView implementation. MainPresenter { ... MainClicked() { // it's required to create IChildView instance here } } How would you implement such creation typically? Shall IMainView has factory method for IChildView or may be it should be separate Views factory. What would you advise? Or maybe there is some misunderstanding of MVP here? Thank you in advance!

  • Recommendations for Open Source Parallel programming IDE

    - by Andrew Bolster
    What are the best IDE's / IDE plugins / Tools, etc for programming with CUDA / MPI etc? I've been working in these frameworks for a short while but feel like the IDE could be doing more heavy lifting in terms of scaling and job processing interactions. (I usually use Eclipse or Netbeans, and usually in C/C++ with occasional Java, and its a vague question but I can't think of any more specific way to put it)

  • Setting many key/value pairs

    - by Andrew
    Hi, I'm working on a rake task which imports from a JSON feed into an ActiveRecord called Person. Person has quite a few attributes and rather than write lines of code for setting each attribute I'm trying different methods. The closest I've got is shown below. This works nicely as far as outputing to screen but when I check the values have actually been set on the ActiveRecord itself it's always nil. So it looks like I can't use .to_sym to solve my problem? Any suggestions? I should also mention that I'm just starting out with Ruby, have been doing quite a bit of Objective-c and now need to embrace the Interwebs :) http = Net::HTTP.new(url.host, url.port) http.read_timeout = 30 json = http.get(url.to_s).body parsed = JSON.parse(json) if parsed.has_key? 'code' updatePerson = Person.find_or_initialize_by_code(parsed['code']) puts updatePerson.code parsed.each do |key, value| puts "#{key} is #{value}" symkey = key.to_sym updatePerson[:symkey] = value.to_s updatePerson.save puts "#{key}....." # shows the current key puts updatePerson[:symkey] # shows the correct value puts updatePerson.first_name # a sample key, it's returning nil end

    hello everyone i have a series of PDF byte arrays in a arraylist files that i wish to concatenate into one file, currently when the PDF application trys to open the file is it corrupted: foreach (byte[] array in files) { using (Stream s = new MemoryStream(downloadbytes)) { s.Write(array, 0, array.Length); } } downloadbytes is the resultant concatenated array of bytes below is another implementation which also failed foreach (byte[] array in files) { System.Buffer.BlockCopy(array, 0, downloadbytes, offset, array.Length); offset += array.Length; } any pointers?

  • Is NAnt in the dead pool?

    - by Andrew Matthews
    I know NAnt sees frequent use (well, I always use it for my CI builds) but there has been no new official release since December 2007. Is the project receiving active development any more or is it dead-pooled? It worries me that if I carry on using it, and it stops tracking the latest version of .NET, I'll eventually be left with a massive job when it comes to upgrading systems to a version of the framework that it can't build. Has everyone else gone over to some other tool like MSBuild these days?

  • Do I have to call release on an objective-c retain class variable when setting it to a new object?

    - by Andrew Arrow
    Say I have: @property (nonatomic,retain) NSString *foo; in some class. And I call: myclass.foo = [NSString stringWithString:@"string1"]; myclass.foo = [NSString stringWithString:@"string2"]; Should I have called [myclass.foo release] before setting it to "string2" to avoid a memory leak? Or the fact that nothing is pointing to the first "string1" object anymore is good enough? And in the dealloc method [foo release] will be called.

  • Why can't you return a List from a Compiled Query?

    - by Andrew
    I was speeding up my app by using compiled queries for queries which were getting hit over and over. I tried to implement it like this: Function Select(ByVal fk_id As Integer) As List(SomeEntity) Using db As New DataContext() db.ObjectTrackingEnabled = False Return CompiledSelect(db, fk_id) End Using End Function Shared CompiledSelect As Func(Of DataContext, Integer, List(Of SomeEntity)) = _ CompiledQuery.Compile(Function(db As DataContext, fk_id As Integer) _ (From u In db.SomeEntities _ Where u.SomeLinkedEntity.ID = fk_id _ Select u).ToList()) This did not work and I got this error message: Type : System.ArgumentNullException, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 Message : Value cannot be null. Parameter name: value However, when I changed my compiled query to return IQueryable instead of List like so: Function Select(ByVal fk_id As Integer) As List(SomeEntity) Using db As New DataContext() db.ObjectTrackingEnabled = False Return CompiledSelect(db, fk_id).ToList() End Using End Function Shared CompiledSelect As Func(Of DataContext, Integer, IQueryable(Of SomeEntity)) = _ CompiledQuery.Compile(Function(db As DataContext, fk_id As Integer) _ From u In db.SomeEntities _ Where u.SomeLinkedEntity.ID = fk_id _ Select u) It worked fine. Can anyone shed any light as to why this is? BTW, compiled queries rock! They sped up my app by a factor of 2.

  • Projects to learn Python

    - by Andrew
    I know this isn't a question about a specific snippet of code or anything, but here goes - I've been messing around with the idea of learning Python since I'm pretty bored with PHP (and web development in general), but I can't think of any projects to help me learn. I've already worked through some of Project Euler with Python, but it's getting old. I know the basics, and I want to write something more fun that will introduce me to new things in Python. Is there a cliche beginner project for Python? (for example, PHP's would be a blog or something similiar) Are there any common Python projects for newcomers, or any uncommon ones that you'd suggest? Any ideas would help.

  • Using NSArray for C-type int comparisons

    - by Andrew Barinov
    I would like to iterate through an NSArray of ints and compare each one to a specific int. All ints are C type ints. The code I am using is as follows: -(int)ladderCalc: (NSArray*)amounts: (int)amount { int result; for (NSUInteger i=0; i< [amounts count]; i++) { if (amount < [amounts objectAtIndex:i]); { // do something } // do something } } However I get an error when comparing the int amount to the result of [amounts objectAtIndex:i] because you cannot compare id to int. Why is the id involved in this case? Shouldn't objectAtIndex just return the object at the index specified? Is it possible to cast the object returned to an C int and then do the comparison? Or should I just dispense with NSArray and do this type of thing in C?

  • How should I be storing objects that I wish to access in reverse order of the way I placed them in

    - by andrew hicks
    I'm following this guide here: http://www.mazeworks.com/mazegen/mazetut/index.htm Or more specficially create a CellStack (LIFO) to hold a list of cell locations set TotalCells = number of cells in grid choose a cell at random and call it CurrentCell set VisitedCells = 1 while VisitedCells < TotalCells find all neighbors of CurrentCell with all walls intact if one or more found choose one at random knock down the wall between it and CurrentCell push CurrentCell location on the CellStack make the new cell CurrentCell add 1 to VisitedCells else pop the most recent cell entry off the CellStack make it CurrentCell endIf endWhile Im writing this in java, My problem is. How should I be storing my visited cells, So that I can access them from reverse order of when I placed them in. Like this? List<Location> visitedCells = new ArrayList<Location>(); Then do I grab with visitedCells.get(visitedCells.size()-1)? Location stores the x, y and z. Not something Im trying to ask you.

  • Logging a certain event only once in ruby

    Are there any logging frameworks in ruby that allow you to log a specific event type only once? logger = IdealLogger.new logger.log(:happy_path, "We reached the happy path") # => logs this message logger.log(:happy_path, "We reached the happy path yet again") # => Doesn't log this logger.log(:sad_path, "We've encountered a sad path!") # => logs this message Also, is there a term for the concept of logging a certain event type only once?

  • Output unicode strings in Windows console app

    Hi I was trying to output unicode string to a console with iostreams and failed. I found this: Using unicode font in c++ console app and this snippet works. SetConsoleOutputCP(CP_UTF8); wchar_t s[] = L"èéøÞ???Sæca"; int bufferSize = WideCharToMultiByte(CP_UTF8, 0, s, -1, NULL, 0, NULL, NULL); char* m = new char[bufferSize]; WideCharToMultiByte(CP_UTF8, 0, s, -1, m, bufferSize, NULL, NULL); wprintf(L"%S", m); However, I did not find any way to output unicode correctly with iostreams. Any suggestions?

  • Caching result of SELECT statement for reuse in multiple queries

    - by Andrew
    I have a reasonably complex query to extract the Id field of the results I am interested in based on parameters entered by the user. After extracting the relevant Ids I am using the resulting set of Ids several times, in separate queries, to extract the actual output record sets I want (by joining to other tables, using aggregate functions, etc). I would like to avoid running the initial query separately for every set of results I want to return. I imagine my situation is a common pattern so I am interested in what the best approach is. The database is in MS SQL Server and I am using .NET 3.5.
