Creating roles is also an issue... I'm baffled!
=> #<Role id: nil, name: nil, description: nil, created_at: nil, updated_at:
nil>
>> role.name = 'test'
=> "test"
>> role.save!
=> true
>> role
=> #<Role name: nil, description: nil, created_at: "2009-07-02 13:04:44",
updated_at: "2009-07-02 13:04:44">
Here's my migration:
require 'active_record/fixtures'
class CreateRoles < ActiveRecord::Migration
def self.up
create_table :roles do |t|
t.string :name
t.string :description
t.timestamps
end
Fixtures.create_fixtures('db/fixtures', File.basename("roles.yml",
'.*'))
end
def self.down
drop_table :roles
end
end
