<%= form_for(@user) do |f| %>
  <% if @user.errors.any? %>
    <div id="error_explanation">
      <h2><%= pluralize(@user.errors.count,"error") %> prohibited this user from being saved:</h2>
 
      <ul>
      <% @user.errors.full_messages.each do |message| %>
        <li><%= message %></li>
      <% end %>
      </ul>
    </div>
  <% end %>
 
  <%= @user.errors.messages[:name] %>
 
  <div class="field">
    <%= f.label :name %><br>
    <%= f.text_field :name %>
  </div>
  <div class="field">
    <%= f.label :email %><br>
    <%= f.text_field :email %>
  </div>
  <div class="field">
    <%= f.label :password %><br>
    <%= f.password_field :password %>
  </div>
  <div class="field">
    <%= f.label :phone %><br>
    <%= f.text_field :phone %>
  </div>
  <div class="actions">
    <%= f.submit %>
  </div>
<% end %>

我想为它下面的每个字段显示表单错误,而不是顶部的所有字段.经过rails guide,但无法知道如何做到这一点.
