Hartl第11章Ajax未定义的局部变量或方法"cookies" [英] Hartl Chapter 11 Ajax undefined local variable or method `cookies'
问题描述
我正在编写Hartl教程,目前在第11.2.5章中使用AJAX的工作跟随按钮.
I am doing the Hartl Tutorial, and am currently in Chapter 11.2.5 A working follow button with AJAX.
我的关系控制器测试失败,我不知道为什么.预期的行为发生在浏览器中.如果删除cookie方法,它将导致许多其他测试失败.我在想什么导致这个问题?
My tests are failing for the Relationship Controller and I can't figure out why. The expected behavior happens in the browser. If I remove the cookies method it causes many other tests to fail. What am I missing that is causing this issue?
require 'spec_helper'
describe RelationshipsController do
let(:user) { FactoryGirl.create(:user) }
let(:other_user) { FactoryGirl.create(:user) }
before { sign_in user, no_capybara: true }
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 }
expect(response).to 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
expect(response).to be_success
end
end
end
这是我的实用工具.rb
include ApplicationHelper
RSpec::Matchers.define :have_error_message do |message|
match do |page|
expect(page).to have_selector('div.alert.alert-error', text: message)
end
end
def sign_in(user, options={})
if options[:no_capybara]
# Sign in when not using Capybara.
remember_token = User.new_remember_token
cookies[:remember_token] = remember_token
user.update_attribute(:remember_token, User.encrypt(remember_token))
else
visit signin_path
fill_in "Email", with: user.email
fill_in "Password", with: user.password
click_button "Sign in"
end
end
这是我的Relationships_controller.rb
class RelationshipsController < ApplicationController
before_action :signed_in_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
这是我的测试输出:

推荐答案
我注意到您将对RelationshipsController的测试放在了 spec/models
中.这真的是本教程所说的吗?尝试将其放在 spec/controllers
下,以便将其视为控制器规范.
I noticed you put your test of RelationshipsController in spec/models
. Is that really what the tutorial says to do? Try putting it under spec/controllers
so it is treated as a controller spec.
