The following code was working on rails 2.0 and doesn’t work on 2.1:
class Person < ActiveRecord::Base
validates_uniqueness_of :email
def self.find(*args)
with_scope(:find => { :conditions => ["status = ?", true]}) do
super
end
end
end
>> p1 = Person.new(:email => "test@domain.com", :status => true)
=> #<Person id: nil, email: "test@domain.com", status: true>
>> p2 = Person.new(:email => "test@domain.com", :status => true)
=> #<Person id: nil, email: "test@domain.com", status: true>
>> p1.save!
=> true
>> p2.save!
ActiveRecord::RecordInvalid: Validation failed: Email has already been taken
>> p1 = Person.find(1)
=> #<Person id: 1, email: "test@domain.com", status: true>
>> p1.status = false
=> false
>> p1.save!
=> true
>> p1 = Person.find(1)
ActiveRecord::RecordNotFound: Couldn’t find Person with ID=1
>> p2.save!
ActiveRecord::RecordInvalid: Validation failed: Email has already been taken
>> Person.find :all
=> []
