...m is that each record includes two fields, the _combination_ of which must be unique to the record set, but each of which may not be unique. So "sam smith", "mary smith" and "sam jones" (stored as fname, lname) all need to pass the validation. Is there an easy way to validate_uniqueness_of a combination of fields within a record? Thanks in advance for any help. Best regards, Bill -------------- next part -------------- An HTML attachment was scrubbed...

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 solution. http://dev.rubyonrails.org/ticket/3143 Tell me, should I patch...

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 a...

...ion of results with these 3 properties. If someone tries to enter a new test result for a test thats already been run on a certain environment with a certain build I want the user to be prompted to update the existing result rather than create a new one. In the result model, I know I can use .... validate_uniqueness_of :test_id, :scope => "xxxxx" .... but I need it to be unique for 2 fields (environment and build) Is there any way to pass 2 values into the scope attribute? If not can anyone suggest how to update the validate_uniqueness_of method to do this? thanks Iain -------------- next part -...

Hi, I have a form that asks users to put in their :first_name and :last_name. How do I validate that their full_name (first_name + last_name) is unique? Thanks!

Hi, I have a member registration form which takes a "Name", "Login", "Password", "Confirm Password" and "Location". In the user model I have added the validation validate_uniqueness_of :login, validate_presence_of :password, :name, :confirm_password. When the member tries to register every thing working fine. I am using same form for user to edit his information. When the user come to edit his information we are not allowing the user to edit the password so that we are hiding th...

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/.

This is really strange - hopefully someone out there may have seen behavior like this before. I have a user successfully created in the Users table of my application. When I try to update a single column using: @user = User.find(:first, :conditions => ["login_name = ?", @login_user.login_name]) @user.new_cookie_key @user.save I get the error:

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

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 to the INSERT (or UPDATE). However, in between the SELECT and INSERT, an offending record might appear. example race con...

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 all, I''ve got a rails and database question. Accounts have jobs, and job numbers should be assigned per account. Account 89 should have jobs 1-whatever, which are not the same as account 67, which has jobs 1-whatever. In the past, I have accomplished this quite easily with: create table job ( accountid int(10) unsigned not null default 0, jobid int(10) unsigned not null

This is pretty much the same as last time around, if you recall. Thanks to Wilson for converting to the new form. I''ve added a few lines. Basically, it iterates over your model associations and does two things. - First, just try to call the association. Usually fixes speeling erors or other such silliness. - Second, try to find a record with an :include on the association. This
