没有路线匹配 [PATCH] "/users/sign_in" Devise Sign_In

Question

我在尝试使用设计登录我的 rails 应用程序时一直收到此错误：

No route matches [PATCH] "/users/sign_in"

我这辈子都弄不明白为什么登录无法使用该设备 gem。我的路线如下：

              Prefix Verb   URI Pattern                    Controller#Action
                root GET    /                              static_pages#home
    new_user_session GET    /users/sign_in(.:format)       devise/sessions#new
        user_session POST   /users/sign_in(.:format)       devise/sessions#create

   user_registration POST   /users(.:format)               devise/registrations#create
   new_user_registration GET    /users/sign_up(.:format)       devise/registrations#new

                     PATCH  /users(.:format)               devise/registrations#update
                     PUT    /users(.:format)               devise/registrations#update
                     DELETE /users(.:format)               devise/registrations#destroy
                home GET    /home(.:format)                static_pages#home
               about GET    /about(.:format)               static_pages#about
             lessons GET    /lessons(.:format)             lessons#index
                     POST   /lessons(.:format)             lessons#create
          new_lesson GET    /lessons/new(.:format)         lessons#new
         edit_lesson GET    /lessons/:id/edit(.:format)    lessons#edit
              lesson GET    /lessons/:id(.:format)         lessons#show
                     PATCH  /lessons/:id(.:format)         lessons#update
                     PUT    /lessons/:id(.:format)         lessons#update
                     DELETE /lessons/:id(.:format)         lessons#destroy

我看到 PATCH /users/sign_in 不是路由，但我不明白为什么它不是由 devise_for :users 创建的？我的印象是这样的调用会生成所有必要的基本身份验证路由。

/app/views/devise/sessions/new.html.erb

<h2>Log in</h2>

<%= form_for(resource, as: resource_name, url: session_path(resource_name)) do |f| %>
  <div class="field">
    <%= f.label :email %><br />
    <%= f.email_field :email, autofocus: true %>
  </div>

  <div class="field">
    <%= f.label :password %><br />
    <%= f.password_field :password, autocomplete: "off" %>
  </div>

  <% if devise_mapping.rememberable? -%>
    <div class="field">
      <%= f.check_box :remember_me %>
      <%= f.label :remember_me %>
    </div>
  <% end -%>

  <div class="actions">
    <%= f.submit "Log in" %>
  </div>
<% end %>

<%= render "devise/shared/links" %>

Answer 1

为什么不能 POST 创建一个新会话？如您的路线所示：

   user_session POST   /users/sign_in(.:format)       devise/sessions#create

Answer 2

我们遇到了完全相同的问题。到目前为止，我找到的最佳解决方案是为这样的补丁请求创建路由：

as :account do
  patch '/accounts/sign_in', to: 'accounts/sessions#create'
end

请注意，我们的 resource_name 是帐户，我们继承了 rails 的会话控制器，因此控制器 'accounts/sessions'。

编辑： 更好的解决方案是更改您的表单以始终创建一个新会话，如下所示：

原代码来自devise tutorial to customize the sign in view：

<%= form_for(:user, :url => session_path(:user)) do |f| %>

将其更改为新操作并使用 post 请求：

<%= form_for(:user, :url => new_session_path(:user), :method => :post) do |f| %>
