In a one-to-many relationship (domain has_many :categories and category belongs_to :domain) In the category model I use: validates_uniqueness_of :name, :case_sensitive => false but upon creation of a category this validation is performed on ALL domains, can I restrict it only to the categories of the current domain, the to which teh category being saved belongs_to ? if yes ? how ? thanks

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, A few months ago someone posted a message about specifying validates_* constraints on a per-attribute basis. I just created a small plugin that allows you to do this. Here''s an example from one of my models: class Country < ActiveRecord::Base attribute :name, :string do |a| a.validates_length :within =>

I have an ActiveRecord subclass that needs to generate a random (hard to guess) token for each record in its corresponding table. Currently I''m doing something like this: def before_create self[''token''] = random_value while self.class.find_by_token(self[''token'']) self[''token''] = random_value

I have this in a model validates_uniqueness_of :aspect, :scope => :user_id In an instance method of the same model I have "save!" but I don''t touch the :aspect attribute in that instance method at all. Whenever that save! command is run however I get this error: ActiveRecord::RecordInvalid: Validation failed: Aspect has already been taken I don''t

My model is very simple, it''s mostly just a join table that represents which tournaments a user has registered for. class Registration < ActiveRecord::Base belongs_to :user belongs_to :tournament validates_presence_of :user_id, :tournament_id validates_uniqueness_of :user_id, :scope => :tournament_id end the validates_uniqueness checks to make sure there''s no

I want to use mocks and stubs to test the controller, but am having trouble getting my validation not to trigger. Here''s the code: # spec: Image.stub!(:find).and_return(@image) @image.should_receive(:save!).once.with(:any_args) put :update, :id => @image.id, :category_id => @category.id, :image => {:name => ''test'', :image_number =>

THE SCHEMA IN THE MODEL a small write up on ''putting the schema in the model'' This is a write up on an issue best covered in a mailing list thread of Januari 2006 (see the links in the text), I repost it because I think it deserves a place on the agenda. == Why? == I was switching back and forward between the model files and the schema.rb -- off course I have

Is it possible to do a validates_uniqueness_of :name, :zip but only in that context? I''d like to be able to have that zip used again, but not in conjunction with a name already with that zip. Does that make sense? -- Posted via http://www.ruby-forum.com/.

Hi Does anyone here know a way who I could remove the validation for a model''s property? For example, I would like to have in one file: class A < ActiveRecord::Base validates_uniqueness :title end And in another file I want to override or rather remove the validation: class A < ActiveRecord::Base # somehow stop validating :title for uniqueness end The

...en, I''d like to know if an object is .valid? inherently - that is, if it meets all the validations that are run on it by itself, but I don''t care if one of the fields is not unique. What''s the best way to determine this - that is, to run all the validations except the validates_uniquness ones? (A common use case is when importing data - it''s important to distinguish between corrupt data, and between data that has already been imported). -- Posted via http://www.ruby-forum.com/.

I''m trying to use stories to drive some high-level design. I''ve got some branching scenarios where I want to follow a scenario, to establish a base situation, and then have different scenarios which ''branch'' out from that state, possibly several levels deep. I asked a bit about this a few days ago, and David pointed out the rather undocumented GivenScenario

Hello, Using shoulda, any ideas how to allow blank when having this test: should validate_uniqueness_of(:email) Thanks. -- J.

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,
