Fields_for 动态标签
我有动态表单，它有一组值。我创建了一个包含我显示的文本字段的部分。在每个文本旁边，我想显示一个包含文本标题的标签。例如，名字和姓氏以前是未知的。我该如何去做呢？ 看来我无法直接访问属性。但是当我使用标签字段时，标签中的变量名称显示而不是实际值。
I have dynamic form which has a set of values. I created a partial which contains text fields which I display. Next to each of them I would like to display a label containing the title of the text. For instance First Name, and Last Name would not be known previously. How do I go about doing that?
It seems that I cannot access the attributes directly. But when I use the label field, the variable name in the label is displayed not the actual value.

出色地！这反映了我对 Rails 的陌生程度。您可以使用
f.object.{attr_name}来完成此操作，并且效果很好。Well! This was a reflection of how new I am to rails. You can do this by using
f.object.{attr_name}and that worked.f.object.{attr_name}对我不起作用，但f.object[:attr_name]对我有用。f.object.{attr_name}didn't work for me, butf.object[:attr_name]did.怎么样：
这将是 Ruby 方式。
What about:
That would be the Rubyish way.
