我按照教程编写测试场景:当用户转到编辑信息页面但尚未登录时,他们将重定向到登录页面,登录后,他们将重定向到编辑页面。但是当我完成所有这些教程时,运行测试并失败,因为wrong number of arguments (0 for 1)
错误。
这是错误信息:
在登录后尝试访问受保护页面时,对非登录用户的AuthenticationPages授权应呈现所需的受保护页面
失败/错误:click_button“登录”
引发ArgumentError: 错误的参数数量(0表示1)
#./app/helpers/sessions_helper.rb:31:inredirect_back_or'
创建'
# ./app/controllers/sessions_controller.rb:11:in
#(eval):2:在click_button' # ./spec/requests/authentication_pages_spec.rb:58:in
块(5级)中..
这是我的spec / requests / authentication_pages_spec.rb
describe "authorization" do
describe "for non-signed-in users" do
let(:user) { FactoryGirl.create(:user) }
describe "when attempting to visit a protected page" do
before do
visit edit_user_path(user)
fill_in "Email", with: user.email
fill_in "Password", with: user.password
click_button "Sign in"
end
describe "after signing in" do
it "should render the desired protected page" do
page.should have_selector('title', text: 'Edit user')
end
end
end
.
.
.
在app / helpers / sessions_helper.rb中,我有两个方法store_location
和redirect_back_or
来存储并重定向回用户在登录前访问过的网址:
module SessionsHelper
.
.
.
def redirect_back_or(default)
redirect_to(session[:return_to] || default)
session.delete[:return_to]
end
def store_location
session[:return_to] = request.url
end
end
然后我在app / controllers / users_controller.rb中使用了store_location
方法:
class UsersController < ApplicationController
before_filter :signed_in_user, only: [:edit, :update]
before_filter :correct_user, only: [:edit, :update]
.
.
private
def signed_in_user
unless signed_in?
store_location
redirect_to signin_url, notice: "Please sign in."
end
end
我在app / controllers / sessions_controller.rb中使用了redirect_back_or
方法:
class SessionsController < ApplicationController
def new
end
def create
user = User.find_by_email(params[:email].downcase)
if user && user.authenticate(params[:password])
sign_in user
redirect_back_or user
else
flash.now[:error] = "Invalid email/password combination"
render 'new'
end
end
我不知道为什么会发生这种错误,我认为redirect_back_or
方法已经采用了参数user
,但它仍然是错误的。有人可以帮我解决这个问题吗?非常感谢。
答案 0 :(得分:2)
更改此session.delete[:return_to]
session.delete(:return_to)
