ruby-on-rails – 我如何指定before_filters？

我想用rspec指定我的控制器before_filter.
我想为它使用ActionController :: Testing :: ClassMethods#before_filters.

我在导轨c中得到了这些结果：

2.0.0p353 :006 > ActionController::Base.singleton_class.send :include,ActionController::Testing::ClassMethods
2.0.0p353 :003 > EquipmentController.before_filters

=> [：process_action,：process_action]

但实际上这是我行动的过滤器：

class EquipmentController < ApplicationController
  before_filter :authenticate_user!

有任何想法吗？

解决方法

这就是我在项目中所做的：

# spec/support/matchers/have_filters.rb
RSpec::Matchers.define :have_filters do |kind,*names|
  match do |controller|
    filters = controller._process_action_callbacks.select{ |f| f.kind == kind }.map(&:filter)
    names.all?{ |name| filters.include?(name) }
  end
end

# spec/support/controller_macros.rb
module ControllerMacros
  def has_before_filters *names
    expect(controller).to have_filters(:before,*names)
  end
end

# spec/spec_helper.rb
RSpec.configure do |config|
  config.include ControllerMacros,type: :controller
end

然后你可以在控制器规格中使用它,例如：

# spec/controllers/application_controller_spec.rb
require 'spec_helper'
describe ApplicationController do
  describe 'class' do
    it { has_before_filters(:authenticate_user) }
  end
end
