similar to: problem validating uniqueness

hi all, i''m working on deploying my app w/ apache and a mongrel cluster. i''ve started by copying the instructions and code from the agile rails book and everything seems to be working fine but apache isn''t forwarding my requests to mongrel the way i expect it should. there''s nothing in the rewrite logs and nothing but 404 errors in the apache error logs.

Well, I''m working on adding a new type of user (organization) to my application, using a different database table than the standard User table (in the end, I think it works out being easier to deal with than creating another column in the original User table for account type). However, I''m running into a user registration problem. I can register both types of users fine,

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''ve got a user object which has quite a few attributes mapped to the database. As of right now I''ve got some validations in the model like: validates_presence_of :password, :message => "You must specify a valid password." validates_confirmation_of :password, :message => "Password doesn''t match the confirmation." validates_presence_of

I have two models User and Team. Also I have a register form where the new user fill in her data and choose a name for a Team. Well, in the user model there are several validations which work fine, but team model also have a validation for a uniqueness name that doesn''t fire up when she gives an existent team''s name. This is the flow it follows: /user/new -> it shows a

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 have a User model with an email attribute. I''m using the following validations: validates_confirmation_of :email validates_format_of :email, :with => RFC822::EmailAddress, :message => "must be a valid address in the form user@domain.com" validates_uniqueness_of :email, :message => "address has already been taken. If you''ve forgotten your

Hello, I''m wanting to use Mocha and Stubba for my tests in place of the default Rails testing with fixtures. I have the following class: class Person < ActiveRecord::Base validates_uniqueness_of :email end and am wondering how I can test to ensure that the validates_uniqueness_of validation is running. Any ideas? -Jonathan

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

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,

In a Rails 2.x validation to check if the name of some model is unique within a some category, I would use: `validates_uniqueness_of :name, :scope => :category_id` In Rails 3, this is replaced with: `validates :name, :uniqueness => true` However, I can''t seem to find a method of defining the uniqueness'' scope. Am I missing something? Thanks, Angelo -- You received

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. Right now, I have the

I am new Ruby on Rails, so excuse me if my question seems pretty obvious. I am trying to validate uniqueness of a filed: class EventType < ActiveRecord::Base belongs_to :sport validates_uniqueness_of :event_type end When I run it, I get this error message: Showing /event_type/new.rhtml where line #27 raised undefined method `each'' for nil:NilClass <select

Hello all, I am working through the depot example in the rails book. If I add a validates_uniqueness_of to a string column in the model, and then try to create a record with a number in this string column I get an SQL error. Looks like the SQL generated to test for uniqueness does not quote the value if it''s numeric even though it''s comparing against a varchar column. It does

Has anybody noticed validates_uniqueness_of missing in rails 3.0 rc2? I''m not sure if this is a bug or I''m just doing something wrong. Here''s what I''m doing. Class 1: class Title < ActiveRecord::Base validates_length_of :language, :is => 3 validates_uniqueness_of :language, :scope => :book_id validate :language,

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, In Debian/testing (mysql-5.0.20, ruby1.8, rails 1.1.0) Im trying to follow up the fourdaysonrails tutorial, and when putting: validates_uniqueness_of :category, :message => "Already exists" in /myapplication/app/model/category.rb I get: NoMethodError in Categories#create undefined method `category'' for #<Article:0x407f6418> RAILS_ROOT:
