Instance Method Details

#resource_for(model, options = {}) ⇒ Object

Attaches this resource to a model.

Note that ActiveSupport before_filter replaces the list of actions for specified filter and not appends to it. For example, the following code will only run filter_a when bar action is invoked:

class FooController < ApplicationController
  before_filter :filter_a, :only => :foo
  before_filter :filter_a, :only => :bar

  def foo; end
  def bar; end
end

For convenience, you can pass additional actions to register with default filters in options. It is also possible to use append_before_filter.

Parameters:

  • model (Class) —

    an ActiveRecord-derived model class

  • options (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (options):

  • :index (Array<Symbol>) —

    Additional actions to be covered by Resource#load_all_resources.

  • :member (Array<Symbol>) —

    Additional actions to be covered by Resource#load_one_resource.

  • :collection (Array<Symbol>) —

    Additional actions to be covered by Resource#load_referenced_resources.
