similar to: Bug? find_by_id(nil) returns object just created

I have a model named User. When running this application from the console I can call User.find_by_id(nil) and it returns nil. When running this application during testing or through WEBrick or Mongrel calling User.find_by_id(nil) returns the newest record in the database. But it only does this the first time you call it with nil. The second time you call User.find_by_id(nil) it returns nil.

I''m playing around with the Postback action recipe listed in the recipes book. Here is the default code given: def edit @recipe = Recipe.find_by_id(params[:id]) || Recipe.new if request.post? @recipe.attributes = params[:recipe] redirect_to :main_url and return if @recipe.save end end Here is what my code sort of ended up looking like, altho i''ve ripped it apart

I read these: http://www.ruby-forum.com/topic/185297#new http://www.freezzo.com/2008/05/14/override-default-find-conditions-for-model/ it works, it override the .find perfectly, however it does not cover .find_by_id or other .find_by_XXX Is there anyway to override all the find function of a modal? I want to set the default "select" for User modal, only return name and id, but not the

This has the look of a "just don''t quite get it yet" problem. I am using the ActiveRecord.find_by_id method to identify the parent object (Quiz) to tie to the child object (Question) at create time. Here is the stdout log: 127.0.0.1 - - [31/Mar/2006:22:43:22 CST] "GET /question/new? parent_quiz=ff2d7022-be0a-11da-9f01-00400506faf5 HTTP/1.1" 200 806

Hi, The following controller method taking me into infinite loop. Once the update action completes I want to reload the ''index'' page.

Hi all - I have written an XML-RPC app using action-web-service. Mostly works well. Except I just noticed that my :datetime types are coming back as :date types. That is, when in the console I query the record via Foo.find_by_id(123) I get back actual datetimes. If I then do it via XML-RPC, fetching that same record I get back dates (ie. hour/minute/second are set to 00:00:00) Any ideas?

I want to isolate and spec methods that are shared by controllers, and live in application.rb. Whereas I usually also provide examples in individual controllers that use these methods, not necessarily all the edge cases and I''d like to isolate the examples. This is the approach I''m taking (thanks to bryanl for suggestions and http://pastie.caboo.se/123626). WDYT? This

Hello, I''m new to rails and I''m trying to wrap my heads around how to spec controllers using RSpec (using rails 3rc1 and rspec 2.0.0.beta.19). The problem I''ve run into is when I want to test that my controllers respond with a 404 for unfound records. Whenever I run the spec, the ActiveRecord::RecordNotFound exception is not caught by rails, causing the spec

How do I validate that a model object''s attribute is a valid foreign key? The problem is, I can''t check if the attribute is a valid foreign key if the attribute doesn''t even exist. For example, every employee must be in a department. In the following code, if an employee''s department_id is not present then Department.find_by_id(department_id) might cause

Hi all, I''ve put new code into my app so that an administrator will have extra privileges (administer users, edit pages). The error is: ''Couldn''t find User without an ID'' So the app is looking for a logged in user when the homepage is accessed. Heres my code: site/index view: <% if is_logged_in? and logged_in_user.has_role?(''Moderator'')

Hi, i''m going to implement a syndication-service, which will get lists in xml with some meta-data an enclosed video files, which will get encoded at the end. The syndication run will be startet every five minutes of a full hour. So i thought to build 4 Worker. One for checking which feeds to syndicate (syndication_worker) at a specific time, one for processing the list

Hi There! I''d like some feedback before I try to implement some funky rails routes based on an acts_as_tree model. I have a Page model that acts_as_tree. I''d like the URLs to look something like this: http://localhost/about-us/staff/jeff or, another example... http://localhost/what-we-do/products/our-great-cms/features/faqs/ So, as many sub-nodes the user creates,

Given this code (which renders rjs), I''m faced with the fixture- driven way of spec-ing or mocking. How the heck to you mock this so the code at line (2) and (4) work right? I''m still struggling with mocks but it seems like this can be done. Forgive the naivety of this question. 1. def change_quantity 2. @line_item = LineItem.find_by_id(params[:id]) 3. unless

Hello, I''m working with scaffold generated controller test code for handling GET requests. Address is the model being tested. Address belongs_to Company, Company has_many addresses.

I am trying to read some information based on a user id, then search the database for the needed info and build an XML file. Everything seems to be working fine; I read the info, I create the xml and even spit "stuff" out to file. The issue is that the "stuff" I am writing to a file is a xml/html cross cluster #@%$ of stuff. Here is some code: if !params[:id].blank?

I am currently experiencing concurrency issues after moving from MySQL to SQLite. My original program worked fined using MySQL but is now returning "SQLite3::BusyException" errors. The same result happens whether or not I enable the allow_concurrency flag. If I do manually acquire a lock on the SQLite DB the problem would disapear, but I thought that rails was supposed to handle this
