Ruby on Rails

I want to use a form's id in javascript that runs after the DOM is loaded, so what method would get the form's id for an object? In other words, there will be erb thus:

<%= form_for(@obj) do |f| %>...<% end %>

so what erb would give me the id which that form will get?

I know I can just give the form a custom id as a workaround, but I really do not need to change the id, just know what it is. (I also can calculate it myself pretty easily, but I'd rather use the same method that RoR uses, for future-proofing.)

This is all a very small issue, given the multiple easy workarounds. I'm just surprised that I could not find anything in the docs or forums. (RoR 3.2, BTW.)
