Question

由于某种原因，Devise在登录索引页面（todo_lists_path）后停止了路由。我不知道发生了什么。有一件事是我实现了茧，但只在我的_form中实现了todo_lists。会发生的事情是它只是回到登录页面而没有在

中签名

我确实在控制台中创建了一个虚拟用户，并在此处尝试登录时呈现的内容：

您的SignIn视图不正确。您已经拥有form_for，但您也使用了<form>代码，这是错误的。因为您没有method或action，默认情况下会使用GET方法将表单数据发送到您当前的网址。

您应该更新您的观点，如下所示：

<h2 class="text-center">Log in</h2>
  <%= form_for(resource, as: resource_name, url: session_path(resource_name)) do |f| %>
    <div class="row">
        <div class="large-12 columns">
              <div>
                <%= f.label :email %>
                <%= f.email_field :email, autofocus: true %>
            </div>
        </div>
    </div>

    <div class="row">
      <div class="large-12 columns">
        <%= f.label :password %>
        <%= f.password_field :password, autocomplete: "off" %>
      </div>
    </div>

    <div class="row">
        <div class="large-12 columns">
          <% if devise_mapping.rememberable? -%>
            <div><%= f.check_box :remember_me %> <%= f.label :remember_me %>
          <% end -%>

          <div class="row">
            <div class="large-12 columns">
                <%= f.submit "Log in", class: "button [tiny small large]"  %>
            </div>
          </div>


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