订单#new

Question

我在将数据输入表格时收到错误。

未定义的方法`价格＆＃39;对于＃

我能够将价格添加到我的订单表中，但是在添加新数据时。我在订单#new中收到了一个N​​oMethodError。我进入了我的文本编辑器并删除了突出显示的代码段，但输入价格的字段消失了所有剩下的是标题，Price。

显示/Users/nncyvallejo90/Documents/springproject/app/views/orders/_form.html.erb第20行：

未定义的方法`价格＆＃39;对于＃

Extracted source (around line #20):

  <div class="field">
    <%= f.label :price %><br>
    **<%= f.text_field :price %>**
  </div>
  <div class="field">
    <%= f.label :comics_name %><br>

模板包含跟踪：app / views / orders / new.html.erb

架构文件，似乎我没有为最后一个表进行迁移。我确实为客户和漫画书进行了迁移。
