I have this in a model: class GenreBadge < ActiveRecord::Base belongs_to :game, counter_cache: :genre_badges_count, touch: true belongs_to :genre validates :game_id, uniqueness: {scope: :genre_id}, allow_blank: true end When I get one existing genre badge genre_badge = game.genre_badges.first genre_badge.game_id = nil genre_badge.save! It creates an validation exception:

I have a model where initially, they we don''t insert an gov_id value because it isn''t known. The field is given a value of "" because it is on the form. I then added code to the ''create'' method to set that value to nil if it is blank which seems to be fine but then it fails this validation (if NULL) validates_length_of :gov_id, :maximum =>

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 =>

I''m using validates_format_of and the validation I want to do works, but I can''t get an error message to be displayed if the data is invalid: validates_format_of :mobile, :with => /\A[\+0-9]+\Z/, :message => " - Wrong" I have another validation some where else that does display the error message: " - Name is too long" validates_length_of :name,

Hello people, I''d like to detect whether an attribute of a model has vaildates_presence_of applied to it so I can automatically apply a mandatory (*) to the field...it doesn''t look easy...any ideas? Cheers, -- Dan Webb http://www.danwebb.net

Here''s the issue: When I submit a form for updating, @person.update_attributes doesn''t work. But the next nested clause for updating images DOES work. How is that possible? However no matter what I do the Person object will not change its attributes. def edit @person = Person.find(params[:id]) if request.post? @person.update_attributes(params[:person])

In the model I have: validates :square_meters_public_land, :barrier_meters, :numericality => { :greater_than_or_equal_to => 0 }, :allow_nil => true but if, in the field, on create, I don''t insert a value I have the error "field is not a number". -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I think I must be doing something wrong... when a form returns params to the controller, empty fields appear to be returned as blank, not nil. so what''s the point of an :allow_nil=>true setting on a validation? it fails because blank is not the same as nil. i would expect either returned empty fields to be nil, or :allow_nil to really be :allow_blank. otherwise i have to do a search

How would I use validations to ensure I either received a blank value or a ten digit number? If I set validates_length_of :field, :in => 0..10 then that would allow any value in-between. The allow_nil => true option does not seem to work. I''ve also tried using this with some combination of validates_numericality_of but cannot get it to work. Any help would be greatly

I''ve been working with the problem that Joe Hosteny has been talking about on this list and on the tickets he''s posted (http://dev.rubyonrails.com/ticket/1196) and have come up with a tentative solution that I''d like to bring up here. What if we use a "conditional" parameter in the validates_* methods? Here''s how it would look like in practice:

I need to call callback only if the validation was successful, but it seems it is called also when validation fails. -- Posted via http://www.ruby-forum.com/.

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.

Hi guys, I''m trying to do some validation on an image upload. Basically I have a model, Property, which has_many :property_images. I need to check that one image has been uploaded at least and so it was suggested I checked the number of images uploaded - @property.property_images.count > 0. Makes sense. I''ve added a validation on my Property model, like - def

I am new to ruby/rails and am having a problem with validates_length_of. It seems to work fine on a varchar field, but when I try it on a char field the extra characters are silently truncated and the message appears that the record was successfully updated. How can I get my app to produce my error message instead? I''ve tried various variations, but here''s one of my tries:

I have some code in my controller which looks like this: if request.post? and @account.save and @user.save ... end and in my Account and User models I have many :validates, like so account.rb validates_presence_of :subdomain, :on => :create validates_uniqueness_of :subdomain, :on => :create, :message => "is already being used" validates_exclusion_of

Hello, I''m currently stunk on this issue for few days and I do not know how to get it fixed. The system always raises this error message : order is closed and here is my order.rb: class Order < ActiveRecord::Base include ActiveMerchant::Billing before_validation :set_status attr_protected :id, :customer_ip, :status, :error_message, :updated_at, :created_at attr_accessor

Hi, Something has been bothering me about model validation: how do I know that the database has not changed in between when I validate my model''s data, and when it actually gets saved to the database? As a simple example, say I have a User model like: class User validates_uniqueness_of :username end When this gets saved to the database, the validation code checks that there is

I use rails-engine as a plugin of the application and I want to localize the validate message from the plugin: validates_length_of :login, :within => 3..40, :on => :create, :message => N_("%{fn} is too short (min is %d characters)") It can not display the according language,where should i set it? I have tried to add require ''gettext/rails''
