我正在完成Ruby on Rails教程,我大部分时间都是通过第9章。由于某种原因,我一直得到这三个错误,我检查了github,看看如果我遗漏了什么,但是我有我应该拥有的。这是我的错误:
1) Authentication signin with valid information followed by signout
Failure/Error: before { click_link "Sign out" }
NameError:
undefined local variable or method `sign_out' for #<SessionsController:0x104c0b9d0>
# ./app/controllers/sessions_controller.rb:19:in `destroy'
# (eval):2:in `send'
# (eval):2:in `click_link'
# ./spec/requests/authentication_pages_spec.rb:44
2) Authentication authorization for non-signed-in users when attempting to visit a protected page after signing in should render the desired protected page
Failure/Error: page.should have_selector('title', :text => 'Edit user')
expected css "title" with text "Edit user" to return something
# ./spec/requests/authentication_pages_spec.rb:65
3) Authentication authorization for non-signed-in users when attempting to visit a protected page after signing in when signing in again should render the default (profile) page
Failure/Error: click_link "Sign out"
NameError:
undefined local variable or method `sign_out' for #<SessionsController:0x104c358c0>
# ./app/controllers/sessions_controller.rb:19:in `destroy'

非常感谢任何帮助!提前谢谢!
答案 0 :(得分:0)
您正在sign_out
实例中调用SessionsController
,但没有定义此类方法。检查“注销”视图中的代码并检查routes.rb
文件,以确保正确映射您选择的任何链接。通常,“退出”会映射到destroy
方法。
答案 1 :(得分:0)
您的错误是因为sign_out
或其继承的父SessionsController
中未定义ApplicationController
方法。
根据第8章中的Rails教程,他有define this method in SessionsHelper
,然后是mixed in到ApplicationController
。我认为将助手混合到控制器中并不好(助手应该仅限于视图; others agree),但这就是教程的布局方式。
