similar to: Problem with setter override on ActiveRecord

Hey.. So I have a model that has a lot of number fields. Each of these go through a process when read in and read out to add/remove commas (between every three numbers) to make them more readable.

I downloaded Wine 1.2 a few days ago so that I could play a game called Wonderland Online. It worked fine for one day. The 2nd day my update manager asked to install updates and since installing them I can't play my game. I run Ubuntu 10.10. As I stated I installed Wine 1.2 and it worked fine with Wonderland Online that first day. (www.wl.igg.com is the website for the game that I play. I

Hi all! I have just found something very strange. Let''s imagine that I have posts that belong to an author. If I do the following (the order doesn''t matter): apost.author = Author.find(3) apost.author_id = 2 I get a post that has both an :author_id => 2 attribute, and an associated Author with id 3. Then, post.save, and the author_id in the DB is 3. I think that this

Hi, I have a model similar Basket shown below. If customer_type is set then it should also set customer to nil. Likewise, if I set customer, it should inspect the customer_type attached to the customer and set accordingly within Basket. However implementing it as below doesn''t seem to work. Am I missing a better way to achieve this? I had also considered using a before_save

Under Rails 2.3.2 using a completely brand new project, I have 2 models: class Author < ActiveRecord::Base # name:string end class Book < ActiveRecord::Base # title:string belongs_to :author # author_id end And a simple test where i create a Book with an Author using the belongs_to and then update the foreign key directly: require ''test_helper'' class BookTest

Regarding validates_associated... Let''s say I have: article belongs_to author But for whatever reason, I want an article to also be written anonymously and therefore not require an author. Then I have: Article: belongs_to :author validates_associated :author But I DON''T have validates_presence_of. What I want to do is validate that an author is valid --if it is

Can anyone clarify something for me? I''ve been having a hard time with write_attribute. If I do (for instance in a callback): write_attribute(:user, user) Is obj.user_id set automatically too? And viceversa, if I do: write_attribute(:user_id, user.id) Does that set obj.user for me? Doesn''t seem like it''s doing that for me. Anyone understands exactly what

Hi there, I''m writing a little application that parses an image file and extracts the camera settings from the file (the EXIF data) and saves all the fields to the database.
