NameError:未定义的局部变量或方法`app' [英] NameError: undefined local variable or method `app'

问题描述

我创建的控制器规范失败并显示以下错误消息:

The controller spec I created fails with the following error message:

NameError: undefined local variable or method `app' for \
  #<RSpec::Core::ExampleGroup::Nested_1::Nested_1::Nested_1:0x00000004424880>

...

# spec/controllers/sessions_conroller_spec.rb
require 'spec_helper'

describe SessionsController do

  before do
    @user = User.gen!
  end

  describe "#create" do
    context "when sending valid email and password" do
      it "renders a json hash ..." do
        post :create, email: @user.email, password: @user.password
        expect(last_response.status).to eq(201)
      end
    end
  end

  describe "#destroy" do
    context "when sending valid email and authentication token" do
      it "renders a json hash ..." do
        delete :destroy, email: @user.email, auth_token: @user.authentication_token
        expect(last_response.status).to eq(200)
      end
    end
  end

end

spec_helper.rb加载一些混入.

ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'rspec/autorun'
require 'capybara/rspec'
Dir[Rails.root.join("spec/support/**/*.rb")].each { |f| require f }

RSpec.configure do |config|
  config.include FactoryGirl::Syntax::Methods
  config.include Rack::Test::Methods, type: :controller
  config.fixture_path = "#{::Rails.root}/spec/fixtures"    
  config.use_transactional_fixtures = true
  config.infer_base_class_for_anonymous_controllers = false
  config.order = "random"
end

推荐答案

我没有像 Jeremy 说的那样配置，仍然有错误

I didn't have this configuration as Jeremy says, and still had the error

我解决了将它添加到 rails_helper.rb 的问题

I solved just adding this to rails_helper.rb

  def app
    Rails.application
  end

但我不确定为什么现在可以工作，知道吗?

But I'm not sure why is working now, any idea?
