我刚刚完成chapter 10 of the Ruby on Rails Tutorial ,添加编辑/更新、索引和销毁用户的能力。在我的应用程序中似乎一切正常,但是当我运行 RSpec 时我的许多测试都失败了。
我的 users_controller_spec 设置与书中完全相同,我的应用程序代码也相同。一个问题可能是我使用的是 Rails 3.1.1 而不是他在书中使用的 Rails 3.0?对于以前的测试来说,这并不是真正的问题,只是偶尔会出现几行不同的代码。我开始后问题开始出现 section 10.2.1 .
这是我看到的错误列表,如果您需要更多信息,请告诉我。谢谢!

更新:
我解决了 2 个错误,但大多数错误仍然存在。一个问题似乎是当测试试图“获取:索引”时,由于重定向(到/signin 页面),它没有找到正确的页面。我没有设置任何重定向(反正是故意的),但也许有人知道这是怎么发生的以及如何解决它?
更新#2:
根据@bkempner 的要求,这里是 users_controller_spec 和 users_controller 的相关代码(首先是 users_controller_spec)。很多代码,但很多错误......:
describe "for signed-in users" do
before(:each) do
@user = test_sign_in(Factory(:user))

end
end
describe "GET 'edit'" do

test_sign_in(@user)
end
it "should be successful" do
get :edit, :id => @user

end
it "should have a flash message" do

end
end
end

test_sign_in(wrong_user)
end

end.should change(User, :count).by(-1)
end
it "should redirect to the users page" do
delete :destroy, :id => @user
response.should redirect_to(users_path)
end
end
end
现在整个 users_controller:
class UsersController < ApplicationController
before_filter :authenticate, :only => [:index, :edit, :update, :destroy]
before_filter :correct_user, :only => [:edit, :update]
before_filter :admin_user, :only => :destroy
def index
@title = "All users"
@users = User.paginate(:page => params[:page])
end
def show
@user = User.find(params[:id])
@title = @user.name
end
def new
@user = User.new
@title = "Sign up"
end
def create
@user = User.new(params[:user])
if @user.save
sign_in @user
flash[:success] = "Welcome to the Sample App!"
redirect_to @user
else
@title = "Sign up"
render 'new'
end
end
def edit
@title = "Edit user"
end
def update
@user = User.find(params[:id])
if @user.update_attributes(params[:user])
flash[:success] = "Profile updated"
redirect_to @user
else
@title = "Edit user"
render 'edit'
end
end
def destroy
User.find(params[:id]).destroy
flash[:success] = "User destroyed."
redirect_to users_path
end
private
def authenticate
deny_access unless signed_in?
end
def correct_user
@user = User.find(params[:id])
redirect_to(root_path) unless current_user?(@user)
end
def admin_user
redirect_to(root_path) unless current_user.admin?
end
end

基本上 RSPEC 需要为登录和退出设置 @current_user 和当前用户。奇怪又烦人,但这也许是人们考虑在生产应用程序中使用 Devise 的原因!
