2. Define the has_many :permissions macro as: ``has_many :permissions, through: :authorizings, source: :permission``

3. Define the #is_authorized! method as: ``is_authorized!(permission: nil, by: nil, at: Time.now)``

4. Define the #is_authorized? method as: ``is_authorized?(permission: nil, at: Time.now)``

### As Permission concern

The As Permission concern do the following tasks for the includer automatically:
1. Define the has_many :authorizings macro as: ``has_many :authorizings, class_name: 'Unidom::Authorization::Authorizing'``

2. Define the #authorize! method as: ``authorize!(authorized, by: nil, at: Time.now)``

3. Define the #authorize? method as: ``authorize?(authorized, at: Time.now)``



## Disable the Model & Migration

If you only need the app components other than models, the migrations should be neglected, and the models should not be loaded.
```ruby
# config/initializers/unidom.rb
Unidom::Common.configure do |options|

  options[:neglected_namespaces] = %w{
    Unidom::Authorization
  }

end
```
