FIXED: Transaction is a reserved word, and it cannot be used even though I put it into its own module. So my guess is Transactions::Transaction still somehow got resolved to the Rails internal Transaction class. Renamed the Transaction (and its subclasses) to Transact and it works fine now.

validations of "type" when using Single Table Inheritance
Sorry if I''m just dumbing out, but is there a reason that when using Single Table Inheritance Rails doesn''t really validate the "type" field or provide some mechanism to do so? seems like a good way to corrupt a database. Because the "type" is also a special attribute, I had to resort to an ugly hack like: class ActiveRecord::Base def type_attr

Custom action on Active Record Validation Failure?
Instead of having it highlight the bad fields when you enter in a record that fails validation, is there a way to make it do an action? I''m looking for something like this: validates_uniqueness_of :user_id,:url => {:controller => "headline", :action => "index"} so that on failing the uniqueness check, it would go to the headline controller. --

Rails validations, how to improve them
Here is a discussion of a problem and potential solution for Rails validations. Rails has a fundamental problem with validations in that it essentially requires you to either 1. Accept the default error messages (which can often lead to ugly and unfriendly messages for the user) 2. Override validation messages at the model level like so validates_uniqueness_of :field, :message =>

validation, concurrency, and transactions
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

Validates uniqueness scope
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
