ruby 2.0.0p0 (2013-02-24 revision 39474) [x86_64-darwin12.3.0] Rails 3.2.13 I have a validates ... :uniqueness constraint on one of the attributes of an ActiveRecord class.

I then send invalid? to the object under test. invalid? returns _false_, and the .errors object for the record shows no errors. A

I want to write a validate routine to check to enforce that a position must be unique in a category. (In another category, it doesn''t have to and shouldn''t need to be unique.) I write this code which works happily for new items: def position_in_category_not_unique @items = Item.find( :all, :conditions => [ "category_id = ? AND position = ?", category_id,

Hi fellow programmers, I was looking for how to keep integrity in some financial transactions and I saw this "This could even happen if you use transactions with the ‘serializable’ isolation level." in the uniqueness page http://api.rubyonrails.org/classes/ActiveRecord/Validations/ClassMethods.html#method-i-validates_uniqueness_of. How this is possible with the serializablo

I am trying to create a model that allows only unique assets to be added to a category. However, they could be added again to a different category. Finally, an asset can be shared across many categories. So my question is how do you check the uniqueness across a join table? This does not compile.... has_and_belongs_to_many :categories, :foreign_key => ''asset_id''

I want to use mocks and stubs to test the controller, but am having trouble getting my validation not to trigger.

I''m looking for the best way to use validation to confirm that an optional field (hostname) is unique only if a value is entered in the form. I was originally following the path shown in Agile Web Development with Rails first edition, page 66, to define the "validate" method, but didn''t have a clue how to include a uniqueness test there.

I have Proposals and Members and Members can vote for a proposal only once. So, I have "Vote belongs_to :member, :proposal", but to make sure a member only votes once, I want to make sure that there isn''t a vote in the db with that member_id and proposal_id. I can just put the appropriate find in a vote.valid? but I wanted to make sure I wasn''t missing a nice rails

I have validates_uniqueness_of :name in my model which works fine when creating a record but doesn''t work when I edit the record.

Hello, I''ve tried to set up a class with acts_as_list with a scope argument that restricts a list to records with the same foreign key.
