Instance Public methods

after_initialize(&block)

Last configurable block to run. Called after frameworks initialize.

Source: show 

# File railties/lib/rails/railtie/configuration.rb, line 70
def after_initialize(&block)
  ActiveSupport.on_load(:after_initialize, yield: true, &block)
end

after_routes_loaded(&block)

Called after application routes have been loaded.

Source: show 

# File railties/lib/rails/railtie/configuration.rb, line 75
def after_routes_loaded(&block)
  ActiveSupport.on_load(:after_routes_loaded, yield: true, &block)
end

app_generators()

This allows you to modify application’s generators from Railties.

Values set on app_generators will become defaults for application, unless application overwrites them.

Source: show 

# File railties/lib/rails/railtie/configuration.rb, line 47

end

app_middleware()

This allows you to modify the application’s middlewares from Engines.

All operations you run on the app_middleware will be replayed on the application once it is defined and the default_middlewares are created

# File railties/lib/rails/railtie/configuration.rb, line 39

before_configuration(&block)

First configurable block to run. Called before any initializers are run.

before_eager_load(&block)

Third configurable block to run. Does not run if config.eager_load set to false.
