My :counter_cache column isn't working properly.
I wouldn't normally ask about a relatively trivial issue like this but I've
been banging my head on this for a bit and haven't gotten anywhere. I must
be missing something simple. Please take a look:
class Comments < ActiveRecord::Base
belongs_to :test_case, :counter_cache => true
end
class TestCases < ActiveRecord::Base
has_many :test_case_to_users
has_many :comments
has_many :users, :through => :test_case_to_users
named_scope :broken, :conditions => [ "broken = ?", true ]
named_scope :fixed, :conditions => [ "broken = ?", false ]
named_scope :for_user, lambda { |user_id| { :include => :users,
:conditions => ["users.id = ?", user_id ] } }
end
class CreateComments < ActiveRecord::Migration
def self.up
create_table :comments do |t|
t.string :name
t.string :body
t.integer :test_case_id
t.timestamps
end
end
def self.down
drop_table :comments
end
end
class CreateTestCases < ActiveRecord::Migration
def self.up
create_table :test_cases do |t|
t.string :name
t.boolean :broken, :default => true
t.integer :comments_count, :default => 0
t.timestamps
end
end
def self.down
drop_table :test_cases
end
end
I'm getting the following:
NoMethodError: undefined method `find' for ActiveRecord::TestCase:Class

Any ideas?
