  2. require ORM

  3. require app_path/config/environment.rb

  4. call Doozer::Initializer.after_orm_init

  5. call Doozer.init_after_orm_gems - initialized in app_path/gems/plugins/init.rb

  6. call Doozer.init_after_orm_plugins - initialized in app_path/gems/plugins/init.rb

.environment ⇒ Object

Requires the root/config/environment.rb hooks.

This is where you can place your code to initialize additional plugins for models, extend ruby, or whatever else your app requires.

Example environment.rb

Time::DATE_FORMATS = “%B %Y”

Doozer::Initializer.after_orm do | config |

p "Extending some ORM, yo!"

end

Doozer::Initializer.before_rackup do | config |

p "Before rackup, horray for rackup!"

end
