similar to: validates_uniqueness_of - how to use multiple values for scope

Hi folks, I have a question regarding validates_uniqueness_of, and similar before-filter-like events attempting to guarantee some DB state prior to modification. >From my reading of ActiveRecord, validate_uniqueness_of appears to cause a SELECT on the underlying table attempting to ensure that a record with ID(s) specified in the validates_uniqueness_of statement is not already present, prior

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/.

I''ve looked at the validates documentation and it appears that validates_uniqueness_of works on only one field at a time. So I can, for example, validate that "sam" is unique to the record set, and that "smith" is unique to the record set. My problem is that each record includes two fields, the _combination_ of which must be unique to the record set, but each of

I have a problem with the usage of validates_uniqueness_of that I hope someone can help throw a light on. With a new record, this validation works fine. But my problem came when I am updating a record. I was not able do it because it tells me that field value already exists. I was actually updating the value of other fields. According to the documentation which says "When the record is

I thought I understood how to grab the session id but in the following code I am getting null for the session id: @foo = Foo.new(:session_id => session[:session_id], :test_id => @test.id) -- Posted via http://www.ruby-forum.com/.

I was wondering if anybody knows an easy way to pass a method name as the scope option to a validates_uniqueness_of validation on a AR model? For example, I have nested models a bit like: class Survey has_many :areas end class Area belongs_to :survey has_many :questions, :order => ''position'' validates_uniqueness_of :position, :scope => : survey_id end class

I have a master record called ''project'' and a child record called ''agycode''. Obviously, agycode has a project_id FK. I wish to make the "descr" field unique ONLY within the ''project_id'' ''scope''. Here are the key pieces of information Agycode fields (id, project_id, descr) Here''s the declaration in the

I have the following ActiveRecord objects: class Recipe < ActiveRecord::Base has_many :ratings, :dependent => true . . . end class Rating < ActiveRecord::Base validates_uniqueness_of :created_by, :scope => :recipe_id belongs_to :recipe, :counter_cache => true . . . end The created_by field on Rating is implemented as a "magic" field similar to this:

Rails 3.2.8 Very strange , it works in dv mode console , but not in a unit test class User < ActiveRecord::Base belongs_to :subdomain validates_uniqueness_of :email, :scope => :subdomain_id class UserTest < ActiveSupport::TestCase def initialize_user @booboo = FactoryGirl.create(:subdomain, name: "booboo") @coocoo = FactoryGirl.create(:subdomain, name:

For example I have table Questions. With fields id, text, and test_id. test_id is not being displayed in my view. I am hoping this means Rails has picked up that it is an id for another model. If so, then how do I utilize that? If not, then do I need to avoid ''id'' in any field names other than the main id field? Thanks! -- Posted via http://www.ruby-forum.com/.

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

Hi, I''ve just been pleasantly surprised, again, by how much Rails does for me, but I am *really* surprised. Surprised as in "how the heck did that happen?" I''d really like to understand this and would appreciate any help. Big picture... the user is presented with a form that allows them to select one or more check boxes to record their allergies. The form uses the

Hi people, Ever since RC 5 (including 1.0) my unit tests that test for inserting duplicate entries fail and throw errors. Each of them implements validate_uniqueness_of to prevent duplicates. While I also put in a ticket for this, I''m wondering if this is actually a defect or maybe intended behaviour afterall. If so, I won''t apply the patch again and look for another

Hi, validate_uniqueness_of has the option :case_sensitive, this option is true by default, there are tests to check that :case_sensitive => false is working, but there isn''t any test to check that, when set to true (the default!), is working, in fact it doesn''t work at. There isn''t a database agnostic way to do a case sensitive search, there is in myql (binary like)
