            </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 %>

这是我的 _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 有一个简单的解决方法：您的 _fields.html.erb 在第一行缺少一些代码。整行应为：

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，由于未附加您的相关代码，因此我对您的其余错误无能为力。

我认为您需要转到调用 _error_messages 部分的文件，并确保您使用以下命令调用它：

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

这是因为您要添加隐藏字段标签。

我也遇到了这个问题，为了解决这个问题，我没有调整迈克尔示例中的代码，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，它似乎接受了来自两个控制器的对象。希望这可以帮助。

截至发稿时，这仍然是本书最新版本中的一个问题。

在本书的前面部分，用户相关表单的字段被重构并放在呈现的部分_fields.html.erb中。shared/error_messages

和文件不需要修改，如书中所述，唯一需要修改的部分users/new是传递给users/edit_fields.html.erbobject: f.objectshared/error_messages
