      <%= pluralize(object.errors.count, "error") %> 
      prohibited this <%= object.class.to_s.underscore.humanize.downcase %> from being saved: 
      </h2> 
      <p>There were problems with the following fields:</p> 
       <ul> 
       <% object.errors.full_messages.each do |message| %> 

       <li><%= message %></li> 
       <% end %> 
       </ul> 
      </div> 
    <% end %>

这是我_micropost_form.html.erb

<%= form_for(@micropost) do |f| %> 


<%= render 'shared/error_messages', :object => f.object %> 

<div class="field"> 
    <%= f.text_area :content %> 
    </div> 
<div class="=actions"> 
    <%= f.submit "Submit" %> 

    </div> 
<%end%>

这是_fields.html.erb

<%= render 'shared/error_messages'%> 
<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 :password_confirmation, "Confirmation" %><br/> 
    <%= f.password_field :password_confirmation %> 

</div>

错误2到15有一个简单的修复：您的_fields.html.erb在第一行缺少一些代码。整行内容应为：

app/views/layouts/_fields.html.erb 
<%= render 'shared/error_messages', object: f.object %> #object: f.object allows the form variable to 
       #access the associated object.

不幸的是，由于您的相关代码未附加，我无法对其余的错误进行任何操作。

从本文开始，这仍然是本书的最新版本中的一个问题。

在本书前面，用户相关表单的字段被重构并放入_fields.html.erb中，shared/error_messages被渲染。

的users/new和users/edit文件不需要进行修改，因为在书中说，而是需要进行修改的部分是_fields.html.erb通过object: f.object到shared/error_messages

我有这个问题，以及，修复它我没有调整迈克尔的例子中的代码，我只是将_fields.html.erb部分从views/users文件夹移动到views/shared文件夹。一旦进入共享文件夹，它似乎接受来自两个控制器的对象。希望这可以帮助。

我认为你需要去被调用_error_messages部分文件，只需确保你使用称其为以下几点：

<%= render 'shared/error_messages', object: f.object %>

这是因为你要添加的隐藏字段标签。
