我如何使config.exceptions_app与rspec一起使用 [英] How do I make config.exceptions_app work with rspec

问题描述

在我的Rails 3.2应用程序中，我试图使用config.exceptions_app通过路由表路由异常以呈现特定于错误的页面（尤其是 401 Forbidden页面）。这是到目前为止我可以进行的配置：

In my Rails 3.2 app, I'm trying to use config.exceptions_app to route exceptions through the routing table to render error-specific pages (especially one for 401 Forbidden). Here's what I've got so far for configuration:

# application.rb
config.action_dispatch.rescue_responses.merge!('Error::Forbidden' => :forbidden)
config.exceptions_app = ->(env) { ErrorsController.action(:show).call(env) }

# development.rb
config.consider_all_requests_local       = false

# test.rb
config.consider_all_requests_local       = false

现在是问题所在了：

module Error
  class Forbidden < StandardError
  end
end

class ErrorsController < ApplicationController
  layout 'error'

  def show
    exception       = env['action_dispatch.exception']
    status_code     = ActionDispatch::ExceptionWrapper.new(env, exception).status_code
    rescue_response = ActionDispatch::ExceptionWrapper.rescue_responses[exception.class.name]

    render :action => rescue_response, :status => status_code, :formats => [:html]
  end

  def forbidden
    render :status => :forbidden, :formats => [:html]
  end
end

当我想渲染401时响应，我只是 raise Error :: Forbidden 在开发环境中完美运行。但是，在rspec中运行示例时，例如：

When I want to render that 401 response, I simply raise Error::Forbidden which, in the development environment works perfectly. But when running an example in rspec, e.g.:

it 'should return http forbidden' do
  put :update, :id => 12342343343
  response.should be_forbidden
end

它不幸失败：

1) UsersController PUT update when attempting to edit another record should return http forbidden
   Failure/Error: put :update, :id => 12342343343
   Error::Forbidden:
     Error::Forbidden

有人可以帮忙吗我了解为什么这在我的测试环境中不起作用？我可以在ApplicationController中放一个#rescue_from，但是如果我必须这样做才能使测试正常工作，我不确定使用 config.exceptions_app 有什么意义。 code>首先。 ：-\

Could someone help me understand why this doesn't work in my test environment? I could put a #rescue_from in ApplicationController, but if I have to do that to get my tests working, I'm not sure what the point of using config.exceptions_app is in the first place. :-\

编辑：作为一种解决方法，我将以下内容放在config / environments / test.rb的末尾。

module Error
  def self.included(base)
    _not_found = -> do
      render :status => :not_found, :text => 'not found'
    end

    _forbidden = -> do
      render :status => :forbidden, :text => 'forbidden'
    end

    base.class_eval do
      rescue_from 'ActiveRecord::RecordNotFound', :with => _not_found
      rescue_from 'ActionController::UnknownController', :with => _not_found
      rescue_from 'AbstractController::ActionNotFound', :with => _not_found
      rescue_from 'ActionController::RoutingError', :with => _not_found
      rescue_from 'Error::Forbidden', :with => _forbidden
    end
  end
end

推荐答案

在 config / environments / test.rb 中设置：

config.action_dispatch.show_exceptions = true
