未定义的方法“protect_against_forgery?"对于 #<#<Class:0x0

问题描述

我的 routes.rb 文件中有以下代码.

I have the following code in my routes.rb file .

resources :users  do
  member do
    get :following,:followers
  end
  collection do
    put :activate_email
  end
 end

我有一个像这样的用户电子邮件激活链接:

And I have a user email activation link like this :

<%= link_to "Activate",activate_email_users_url(email_token: @user.email_token),method: :put  %>

当我点击激活链接时，这是生成的网址

When I click on the activate link , this is the url that is generated

 http://localhost:3000/users/activate_email?email_token=WWNvMN-r_lXgovrQiDlSSQ

更新:好的，所以我想我知道问题是什么.当我查看我的 gmail 中包含 link_to 的激活电子邮件的 html 源代码时，没有

Update: Ok, So I think I kno what the problem is . When I look at the html source of the activation email in my gmail which contains the link_to , there is no

data-method='put'

.所以这似乎是问题所在.它总是发送默认的 GET 请求而不是 PUT.这是我的 user_mailer/registration_confirmation.html.erb 文件

. So that seems to be the problem . It is always sending a default GET request instead of PUT.This is my user_mailer/registration_confirmation.html.erb file

  <%= javascript_include_tag "application" %>
</head>

请点击以下链接激活您的邮箱<%= link_to "Activate",activate_email_users_url(email_token: @user.email_token), 方法: :put %>

Please click on the following link to activate your email <%= link_to "Activate",activate_email_users_url(email_token: @user.email_token), method: :put %>

这给出了以下错误:

undefined method `protect_against_forgery?' for #

So , the code <%= javascript_include_tag "application" %> 

导致了这个错误.有没有办法解决这个问题?

is causing this error. Is there any way around this ?

推荐答案

抱歉，我不知道您的目的，但显然您有激活用户的目的.试试这个，如果这个解决方案不起作用，请告诉我你在控制器上的操作(activate_email)！

Sorry, I do not know your purpose, but apparently you have a purpose to activate user.Try this, if this solution not work, please tell me your action (activate_email) on controller!

查看 rake routes 输出:

activate_email_users PUT/users/activate_email(.:format) users#activate_emailuser GET/users/:id(.:format) users#show

当你生成

http://localhost:3000/users/activate_email?email_token=WWNvMN-r_lXgovrQiDlSSQ

您的问题是 activate_email 被认为是 :id

Your problem was activate_email considered to be :id

users/activate_email =>users/:id

以及解决您的问题:

尝试从链接中删除 method.最好在路由文件中指定 method.如何通过放入路由替换匹配:

Try removing the method from the link. Its better specifying the method in your routes file. How about replacing match by put in routes as :

resources :users  do
  member do
    get :following,:followers
  end
end
put "/users/activate_email/:email_token" => "users#activate_email", :as => "activate"

并在视图中

<%= link_to "Activate", activate_path(:email_token => @user.email_token)  %>

我还没有测试过这个，但我想这已经足够了.

I have not tested this, but I guess this will suffice.
