  • Drupal auto change user role in module

    - by Marques
    I am trying to write a module that will change a user's permissions once a node form is inserted into the database. I already have a role assigned when a user registers, but i want that role to be changed once they create a 'company' profile in this case which is when they fill out a cck form of 'company_post' type. My code is below... switch ($op) { case 'insert': if ($node->type == 'company_post') { } ? im not sure what to put in the if statement because I don't really know how to reference the users roles or how to change them. ? So my question is what code can I use to change the users current role to a new role? (Both roles are already created in drupal and have seperate permissions)

  • adding model validation errors in rescue

    - by ash34
    I have the following model with a virtual attribute class Mytimeperiod < ActiveRecord::Base validates presence of :from_dt validates_format_of :from_dt, :with => /\A\d{2}\/\d{2}\/\d{4}\Z/, :message => "format is mm/dd/yyyy" def from_dt self.from_date.strftime("%m/%d/%Y") if !self.from_date.blank? end def from_dt=(from_dt) self.from_date = Date.parse(from_dt) rescue self.errors.add_to_base("invalid from dt") end end I am using <%= f.error_messages %> to display the error messages on the form. I am using from_dt as a virtual attribute (string). The 'presence of' and 'format of' validation errors show up on the form, but when the user enters an invalid date format on the form and Date.Parse raises an exception I have a 'errors.add_to_base' statement in the rescue clause. Can anyone tell me why this error does not show up in the form error messages when I disable the 'format of' validation. thanks.

  • Java Compiler: Optimization of "cascaded" ifs and best practices?

    - by jens
    Hello, does the Java Compiler optimize a statement like this if (a == true) { if (b == true) { if (c == true) { if(d == true) { //code to process stands here } } } } to if (a == true && b==true && c==true && d == true) So thats my first question: Do both take exactly the same "CPU Cycles" or is the first variant "slowlier". My Second questin is, is the first variant with the cascaded if considered bad programming style as it is so verbose? (I like the first variant as I can better logically group my expressions and better comment them (my if statements are more complex than in the example), but maybe thats bad proramming style?) and even slowlier, thats why I am asking... Thanks Jens

  • user table with javaDB and Hibernate from within grails

    - by Ralf
    let's see if I can ask this in an understandable way... I started with grails and created a domain class called user. As far as I understand, Hibernate is used to map this domain class to the database. This works pretty fine with hsqldb. Now I tried to switch to javaDB and get an error message because the table is called "user" (which seems to be a reserved word for javaDB). So a statement like create table user ... will result in an error message. create table "user" ... works, but Hibernate seems not put put the table name in quotes. How can I configure Hibernate to use quotes in order to make it work with my table name? PS: yes, I know, I could map the domain class to another table name... :-)

  • NHibernate Criteria - How to filter on combination of properties

    - by DavGarcia
    I needed to filter a list of results using the combination of two properties. A plain SQL statement would look like this: SELECT TOP 10 * FROM Person WHERE FirstName + ' ' + LastName LIKE '%' + @Term + '%' The ICriteria in NHibernate that I ended up using was: ICriteria criteria = Session.CreateCriteria(typeof(Person)); criteria.Add(Expression.Sql( "FirstName + ' ' + LastName LIKE ?", "%" + term + "%", NHibernateUtil.String)); criteria.SetMaxResults(10); It works perfectly, but I'm not sure if it is the ideal solution since I'm still learning about NHibernate's Criteria API. What are the recommended alternatives? Is there something besides Expression.Sql that would perform the same operation? I tried Expression.Like but couldn't figure out how to combine the first and last names. Should I map a FullName property to the formula "FirstName + ' ' + LastName" in the mapping class? Should I create a read only FullName property on the domain object then map it to a column?

  • implementing ioctl() commands in FreeBSD

    - by thecoffman
    I am adding some code to an existing FreeBSD device driver and I am trying to pass a char* from user space to the driver. I've implemented a custom ioctl() command using the _IOW macro like so: #define TIBLOOMFILTER _IOW(0,253,char*) My call looks something like this: int file_desc = open("/dev/ti0", O_RDWR); ioctl(file_desc, TIBLOOMFILTER, (*filter).getBitArray()); close(file_desc); When I call ioctl() I get: Inappropriate ioctl for device as an error message. Any guess as to what may be doing wrong? I've defined the same macro in my device driver, and added it to the case statement.

  • MySQL query cache and PHP variables

    - by Saif Bechan
    I have seen the following statement made about the query cache: // query cache does NOT work $r = mysql_query("SELECT username FROM user WHERE signup_date >= CURDATE()"); // query cache works! $today = date("Y-m-d"); $r = mysql_query("SELECT username FROM user WHERE signup_date >= '$today'"); So the query cache only works on the second query. I was wondering if the query cache will also work on this: define('__TODAY',date("Y-m-d")); $r = mysql_query("SELECT username FROM user WHERE signup_date >= '".__TODAY."'");

  • Manually inserting varbinary data into SQL Server

    - by Jeremy Jarrell
    Hi, We have a SQL Server table for user settings. Originally the settings were domain objects which had been serialized as XML into the table but we recently begun serializing them as binary. However, as part of our deployment process we statically pre-populate the table with predefined settings for our users. Originally, this was as simple as copying the XML from a customized database and pasting it into an INSERT statement that was ran after the database was built. However, since we've moved to storing the settings as binary data we can't get this to work. How can we extract binary data from a varbinary column in SQL Server and paste it into a static INSERT script? We only want to use SQL for this, we don't want to use any utilities. Thanks in advance, Jeremy

  • Unable to specify abstract classes in TPH hierarchy in Entity Framework 4

    - by Lee Atkinson
    Hi I have a TPH heirachy along the lines of: A-B-C-D A-B-C-E A-F-G-H A-F-G-I I have A as Abstract, and all the other classes are concrete with a single discriminator column. This works fine, but I want C and G to be abstract also. If I do that, and remove their discriminators from the mapping, I get error 3034 'Two entities with different keys are mapped to the same row'. I cannot see how this statement can be correct, so I assume it's a bug in some way. Is it possible to do the above? Lee

  • iPhones SDK: Setting a relationship property object using core data?

    - by Harkonian
    I'm using core data in my app. I have two entities that are related: EntityA and EntityB. EntityA has a property of type "relationship" with EntityB. In addition, both of these entities are defined classes (not the default NSManagedObject). I'm inserting a new object into my data like this: EntityA *newEntityA = [NSEntityDescription insertNewObjectForEntityForName:@"EntityA" inManagedObjectContext:self.managedObjectContext]; newEntityA.name = @"some name"; newEntityA.entityB.name = @"some other name"; The problem is entityB.name is null. Even if I add an NSLog() statement right after assigning the value, it is null. What is the proper way of setting my "name" property of EntityB when EntityB is a property of EntityA?

  • Why is the form action attribute empty on production server?

    - by Ozzy
    After deploying a ASP.NET WebForms application to a production server some of the ajax calls has stopped working for me. After some debugging I found out that the following statement (in the internal client-method WebForm_DoCallback) was causing the problem: xmlRequest.open("POST", action, true); The problem seemed to be that the action-variable was empty so after checking the rendered html I found out that the form-tag rendered on the production server looks like: <form method="post" action="" id="Form1"> However, on my developer machine I get the following: <form method="post" action="default.aspx" id="Form1"> So, why would the action-attibute render on my dev.machine but not on the production server? This seems to be the case only for one specific web form, when I look on other pages the action-attribute renders correctly. Any suggestions or ideas would be helpful!

  • pl/sql object types "ORA-06530: Reference to uninitialized composite" error

    - by mutoss
    hi, i have a type as follows: CREATE OR REPLACE TYPE tbusiness_inter_item_bag AS OBJECT ( item_id NUMBER, system_event_cd VARCHAR2 (20), CONSTRUCTOR FUNCTION tbusiness_inter_item_bag RETURN SELF AS RESULT ); CREATE OR REPLACE TYPE BODY tbusiness_inter_item_bag AS CONSTRUCTOR FUNCTION tbusiness_inter_item_bag RETURN SELF AS RESULT AS BEGIN RETURN; END; END; when i execute the following script, i got a "Reference to uninitialized composite" error, which is imho quite suitable. DECLARE item tbusiness_inter_item_bag; BEGIN item.system_event_cd := 'ABC'; END; This also raises the same error: item.item_id := 3; But if i change my object type into: CREATE OR REPLACE TYPE tbusiness_inter_item_bag AS OBJECT ( item_id NUMBER(1), system_event_cd VARCHAR2 (20), CONSTRUCTOR FUNCTION tbusiness_inter_item_bag RETURN SELF AS RESULT ); then the last statement raises no more error (where my "item" is still uninitialized): item.item_id := 3; Shouldn't i get the same ORA-06530 error? ps: Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bi

  • Shortest way of attaching multiple DOM elements to one event handler using Jquery?

    - by Camsoft
    I need to attach a single event handler to multiple DOM elements using jQuery. I'm currently achieving this using jQuery's each() method. See below: $([elm1, elm2, elm3]).each(function() { this.click(eventHandler); }); I was wondering if there is a way to do this without using the each method and closure. I thought I would be able to do something like: $(elm1, elm2, elm3).click(eventHandler); This kind of statement works using Prototype.js but not in jQuery.The reason I ask the question is because after using both Prototype.js and jQuery I have found that jQuery requires simpler statements to achieve the same tasks in almost every area so I assume there must be a better way of doing this?

  • idomatic batch processing of text in emacs?

    - by Stephen
    In python, you might do something like fout = open('out','w') fin = open('in') for line in fin: fout.write(process(line)+"\n") fin.close() fout.close() (I think it would be similar in many other languages as well). In emacs lisp, would you do something like (find-file 'out') (setq fout (current-buffer) (find-file 'in') (setq fin (current-buffer) (while moreLines (setq begin (point)) (move-end-of-line 1) (setq line (buffer-substring-no-properties begin (point)) ;; maybe (print (process line) fout) ;; or (save-excursion (set-buffer fout) (insert (process line))) (setq moreLines (= 0 (forward-line 1)))) (kill-buffer fin) (kill-buffer fout) which I got inspiration (and code) from here. Or should I try something entirely different? And how to remove the "" from the print statement? Thanks!

  • Update DataBase on clicking in button, after editing gridview (not automatically saving in DB, but a

    - by gaponte69
    0 vote down star I am using GridView in asp .net and editing data with edit command field property (as we know after updating the edited row, we automatically update the database), and I want to use transactions (with begin to commit statement - including rollback) to commit this update query in database, after clicking in some button (after some events for example), not automatically to insert or update the edited data from grid directly to the DB...so I want to save them somewhere temporary (even many edited rows - not just one row) and then to confirm the transaction - to update the real tables in database... Any suggestions are welcomed... I've used some good links, but very helpful, like: http://www.asp.net/learn/data-access/tutorial-63-cs.aspx http://www.asp.net/learn/data-access/tutorial-66-cs.aspx etc... etc...

  • Why doesn't Linux use the hardware context switch via the TSS?

    - by smwikipedia
    Hi guys! I read the following statement: The x86 architecture includes a specific segment type called the Task State Segment (TSS), to store hardware contexts. Although Linux doesn't use hardware context switches, it is nonetheless forced to set up a TSS for each distinct CPU in the system. I am wondering: Why doesn't Linux use the hardware support for context switch? Isn't the hardware approach much faster than the software approach? Is there any OS which does take advantage of the hardware context switch? Does windows use it? At last and as usual, thanks for your patience and reply.

  • nmake: can a batch file run as a art of a command block, affect the environment of the nmake.exe pro

    - by Cheeso
    I think in nmake if I do this: example : set value=77 echo %%value%% The result will display 77 on the console. Is there a way for me to invoke a .cmd or .bat file that will affect the environment of the nmake.exe process? Suppose I put the statement set value=77 in a file called "setvalue.cmd". Then change the makefile to this: example : setvalue echo %%value%% I get: %value% Alternatively, if there's a way to set a macro within a command block, that would also work. Or, a way to set the value of a macro from a batch file, even outside a command block.

  • Externalize Javascript in YAP

    - by Haseeb Khan
    I am working on a Yahoo! App which requires certain external Javascript Frameworks to be loaded and used. Also in the Yahoo! App Best Practices Guide, it is also mentioned that the sources should be externalized, however, externalization isn't working for me. I am using the standard procedure to load the external JS file like the following: <script src="http://www.google.com/js/nxsl.1.js"></script> But the above statement is giving me an error that external sources are not allowed. Is there any way to use external JS files as I don't want to include all of my JS Login inline, it doesn't make sense to me and majorly my code won't be re-usable. Any thoughts ?
