无法使用nested_form_for gem

我是第一次使用 nested_form_for gem。我不知道这是一个问题还是我使用错误，但我收到了“未定义的方法nested_form_for”错误。正如您所看到的，我有一个非常规则的表单：

  <%= nested_form_for @user do |f| %>
        <%= f.fields_for :godfathers do |godfather_form| %>
            <%=  godfather_form.label :name %> <br/>
            <%=  godfather_form.text_field :name %> <br/>
            <%=  godfather_form.label :description %> <br/>
            <%=  godfather_form.text_field :description %> <br/>
            <%=  godfather_form.link_to_remove "Remove this godfather" %>
        <% end %>
       <%= f.link_to_add "Add a godfather", :godfathers %>
   <% end %>

顺便说一句，我安装了 gem 并运行： railsgeneratenested_form:install 命令 来生成nested_form.js 文件，该文件包含在我的布局中jquery 包含(<%= javascript_include_tag :default, 'nested_form' %>)。

有人也用这个宝石吗？

谢谢！

I am using the nested_form_for gem for the first time. I don't know if this is an issue or if I am using it wrong, but I am getting an "undefined method nested_form_for" error.
I have a pretty regular form as you can see:

  <%= nested_form_for @user do |f| %>
        <%= f.fields_for :godfathers do |godfather_form| %>
            <%=  godfather_form.label :name %> <br/>
            <%=  godfather_form.text_field :name %> <br/>
            <%=  godfather_form.label :description %> <br/>
            <%=  godfather_form.text_field :description %> <br/>
            <%=  godfather_form.link_to_remove "Remove this godfather" %>
        <% end %>
       <%= f.link_to_add "Add a godfather", :godfathers %>
   <% end %>

By the way, I installed the gem and ran the: rails generate nested_form:install command to generate the nested_form.js file that I included in my layout after the jquery inclusion(<%= javascript_include_tag :default, 'nested_form' %>).

Anyone using this gem as well?

Thanks!
