Question

我有1.2.6号铁路:

<%= form_tag(:action => "login_in_user") %>
 <p>
          <label for="header">Username</label>
          <%= text_field("user", "name") %>       
          </p>          
         <p>
          <label for="header">Password</label>
          <%= password_field("user", "password") %>                
          </p>
          <div class="spacer"></div>
          <%= write_flash_notice(:label => true)%>
          <%= error_messages_for  user  %>
 <p>
          <label for="submit">&nbsp;</label>          
    <%= submit_tag("login") %>     
           </p>
<%= end_form_tag %>

我确实试图用表格(用于:login_in_user)来重写这 w。

How should I rewrite it?

UPDATE - Rails§! Had of course forgot the <%= yield %> in layout

Answer 1

Is there a @user instance present? If so:

<%= form_for @user, :url => { :action => :login_in_user } do |f| %>
  <p>
    <%= f.label :name %>
    <%= f.text_field :name %>
  </p>
  <p>
    <%= f.label :password %>
    <%= f.password_field :password %>
  </p>
  <%= error_messages_for :user %>
  <p>
    <%= f.label :submit %>
    <%= f.submit :login %>
  </p>
<% end %>
