Rails 4 Devise 3.1.1 ActionController :: UnknownFormat in Devise :: RegistrationsController＃new [英] Rails 4 Devise 3.1.1 ActionController::UnknownFormat in Devise::RegistrationsController#new

问题描述

我正在使用Devise 3.1.1进行Rails 4应用程序的用户验证。当我点击/users/sign_up.user链接Rails抛出以下异常：

  ActionController :: UnknownFormat in Devise :: RegistrationsController＃新
 ActionController :: UnknownFormat 
 
 Rails.root：/ home / rehan / odesk_work / kiefer-waight / ujoin / ujoin-www

我实际上是Devise 3.0。 0.rc当启动应用程序时，我认为升级到3.1.1可能会解决问题，但没有。在SO / google / devise github项目中找不到任何有用的东西。任何想法如何解决它。谢谢！

解决方案

我不想更改Devise生成的默认链接，后者在每个链接的末尾附加了.user 。 Devise生成以下链接：

new_user_registration_path（resource_name）new_user_session_path（resource_name）new_user_password_path（resource_name）

$作为link_to方法中的路径的参数，resource_name是用户，它指示它将.user用作格式。所以我刚从每个路径删除resource_name。我不知道为什么Devise这样做呢！

I am working on a Rails 4 app using Devise 3.1.1 for user authentication. When I click on /users/sign_up.user link Rails throws following exception:

ActionController::UnknownFormat in Devise::RegistrationsController#new
ActionController::UnknownFormat

Rails.root: /home/rehan/odesk_work/kiefer-waight/ujoin/ujoin-www

I was actually on Devise 3.0.0.rc when started the app, I thought upgrading the devise to 3.1.1 might solve the problem, but it didn't. Couldn't find anything useful on SO/google/devise github project. Any idea how to work around it. Thanks!

解决方案

I did not want to change default links produced by Devise which appended ".user" at the end of each link. Devise produced following links:

new_user_registration_path(resource_name) new_user_session_path(resource_name) new_user_password_path(resource_name)

resource_name, which is user, as parameter to the path in link_to method which tells it to use ".user" as format. So I just removed resource_name from each path. I wonder why Devise does this though!
