测试未通过:未定义的方法“验证！"对于零:NilClass? [英] Test not passing: undefined method `authenticate!' for nil:NilClass?

问题描述

我有以下失败:

<块引用>

失败:1) 使用 Ajax 创建关系的 RelationshipsController 应该增加关系计数失败/错误:xhr:post，:create，关系:{follow_id:other_user.id}无方法错误:未定义的方法认证！"对于零:NilClass# ./spec/controllers/relationships_controller_spec.rb:14:in `block (4 levels) in <top (required)>'# ./spec/controllers/relationships_controller_spec.rb:13:in `block (3 levels) in <top (required)>'

但很奇怪，如果我访问该站点，事情就会起作用(如果我单击 Follow 按钮，followers 计数器会增加:

最奇怪的是没有任何身份验证！relationships_controller_spec.rb 中的方法:

需要'spec_helper'描述 RelationshipsController 做let(:user) { FactoryGirl.create(:user) }let(:other_user) { FactoryGirl.create(:user) }{登录用户}之前描述与 Ajax 建立关系" do它应该增加关系计数"做期待做xhr :post, :create, 关系: {follow_id: other_user.id }end.to change(Relationship, :count).by(1)结尾它应该成功响应"做xhr :post, :create, 关系: {follow_id: other_user.id }response.should be_success结尾结尾描述破坏与 Ajax 的关系" do{ user.follow!(other_user) } 之前让(:关系){ user.relationships.find_by_followed_id(other_user)}它应该减少关系计数"吗期待做xhr :delete, :destroy, id:relationship.idend.to change(Relationship, :count).by(-1)结尾它应该成功响应"做xhr :delete, :destroy, id:relationship.idresponse.should be_success结尾结尾结尾

不在控制器中:

class RelationshipsController <应用控制器before_filter :authenticate_user!定义创建@user = User.find(params[:relationship][:followed_id])current_user.follow!(@user)response_to do |格式|format.html { redirect_to @user }格式.js结尾结尾销毁@user = Relationship.find(params[:id]).followedcurrent_user.unfollow!(@user)response_to do |格式|format.html { redirect_to @user }格式.js结尾结尾结尾

可能是什么问题?

(顺便说一下，这些测试是按照 Ruby on Rails 教程.之后，我删除了所有身份验证系统，因为我想使用设计.)

解决方案

我必须添加:

spec_helpers.rb:

RSpec.configure 做 |config|config.include Devise::TestHelpers, :type =>:控制器结尾

I have the following failure:

Failures:

  1) RelationshipsController creating a relationship with Ajax should increment the Relationship count
     Failure/Error: xhr :post, :create, relationship: { followed_id: other_user.id }
     NoMethodError:
       undefined method `authenticate!' for nil:NilClass
     # ./spec/controllers/relationships_controller_spec.rb:14:in `block (4 levels) in <top (required)>'
     # ./spec/controllers/relationships_controller_spec.rb:13:in `block (3 levels) in <top (required)>'

But it is very strange, if I visit the site, the thing works (the followers counter does increment if I click the Follow button:

And the weirdest thing is that there isn't any authenticate! method in relationships_controller_spec.rb:

require 'spec_helper'

describe RelationshipsController do

  let(:user) { FactoryGirl.create(:user) }
  let(:other_user) { FactoryGirl.create(:user) }

  before { sign_in user }

  describe "creating a relationship with Ajax" do

    it "should increment the Relationship count" do
      expect do
        xhr :post, :create, relationship: { followed_id: other_user.id }
      end.to change(Relationship, :count).by(1)
    end

    it "should respond with success" do
      xhr :post, :create, relationship: { followed_id: other_user.id }
      response.should be_success
    end
  end

  describe "destroying a relationship with Ajax" do

    before { user.follow!(other_user) }
    let(:relationship) { user.relationships.find_by_followed_id(other_user) }

    it "should decrement the Relationship count" do
      expect do
        xhr :delete, :destroy, id: relationship.id
      end.to change(Relationship, :count).by(-1)
    end

    it "should respond with success" do
      xhr :delete, :destroy, id: relationship.id
      response.should be_success
    end
  end
end

Neither in the controller:

class RelationshipsController < ApplicationController
  before_filter :authenticate_user!

  def create
    @user = User.find(params[:relationship][:followed_id])
    current_user.follow!(@user)
    respond_to do |format|
      format.html { redirect_to @user }
      format.js
    end
  end

  def destroy
    @user = Relationship.find(params[:id]).followed
    current_user.unfollow!(@user)
    respond_to do |format|
      format.html { redirect_to @user }
      format.js
    end
  end
end

What could be the problem?

(By the way, these test were made following the Ruby on Rails Tutorial. After that, I removed all the authentication system because I wanted to use Devise.)

解决方案

I had to add this:

spec_helpers.rb:

RSpec.configure do |config|
  config.include Devise::TestHelpers, :type => :controller
end
