Rails如何以编程方式从表单获取HTML ID

Question

Say I have a Rails form like the following

 <% form_for @model do |f| %>
   <%= f.label :column %>
   <%= f.check_box :column %>
 <% end %>

Is there a way I can get the html id that will be generated for the 'column' check box? What would be great is if there was a way to add in

  <%= f.observe_field :column, options %>

Anyone know how to add this to FormBuilder?

Answer 1

For generating an element's id programatically, see this . As it seems, there is no easy way out.

You could add this to FormBuilder by wrapping up certain field tags. See for example this .
