Ruby Rails自定义表单生成器。自定义文本字段

我试图在rails中创建自定义表单生成器来转换此代码

    <div class="row collapse">
      <div class="large-4 columns">
        <%= builder.label :vacancy_title, "Title of the Vacancy", class: "right inline" %>
      </div>
      <div class="large-8 columns">
        <%= builder.text_field :vacancy_title, class: "tiny" %>
      </div>
    </div>

您需要将内部div的

content\u标记连接在一起。content_标记方法使用块的返回值来确定其内容。您正在运行包含
text\u field\u标记的div的代码，但实际上并未将其包含在外部“row collapse”div中，因为它未包含在块的返回值中

#form_builders/custom_form_builder.rb
class CustomFormBuilder < ActionView::Helpers::FormBuilder
  def t_field(name, title, *args)

    @template.content_tag :div, class: "row collapse" do
      (@template.content_tag :div, class: "large-8 columns" do
        text_field_tag(name, *args)
      end) +

      (@template.content_tag :div, class: "large-4 columns" do
        @template.content_tag :h5 do
          label(title, options[:label], class: "right inline")
        end
      end)
    end
  end
end

类CustomFormBuilder
Hello Levi，谢谢，但在我重新启动rails服务器后，返回“custom_form_builder.rb:8:语法错误，意外“+”，需要关键字_end”。谢谢你，Levi，我解决了这个问题，感谢你的建议（编辑了我的问题）。我需要为两个块添加括号
#form_builders/custom_form_builder.rb
class CustomFormBuilder < ActionView::Helpers::FormBuilder
def t_field(name, title, *args)
   @template.content_tag :div, class: "row collapse" do
     @template.content_tag :div, class: "large-8 columns" do
   text_field_tag(name, *args)
     end

   @template.content_tag :div, class: "large-4 columns" do
     @template.content_tag :h5 do
       label(title, options[:label], class: "right inline")
     end
   end

 end
end

class LabeledFormBuilder < ActionView::Helpers::FormBuilder
  def t_field(name, title, *args)
    @template.content_tag :div, class: "row collapse" do
      (@template.content_tag :div, class: "large-4 columns" do
        @template.content_tag :h5 do
          label(name, title, *args, class: "right")
        end
      end) +
      (@template.content_tag :div, class: "large-8 columns" do
        @template.text_field_tag("#{object_name}[#{name}]")
      end)
    end
  end
end

#form_builders/custom_form_builder.rb
class CustomFormBuilder < ActionView::Helpers::FormBuilder
  def t_field(name, title, *args)

    @template.content_tag :div, class: "row collapse" do
      (@template.content_tag :div, class: "large-8 columns" do
        text_field_tag(name, *args)
      end) +

      (@template.content_tag :div, class: "large-4 columns" do
        @template.content_tag :h5 do
          label(title, options[:label], class: "right inline")
        end
      end)
    end
  end
end
