Compare with:

dom_class(record_or_class, prefix = nil)

The DOM class convention is to use the singular form of an object or class.

dom_class(post)   # => "post"
dom_class(Person) # => "person"

If you need to address multiple instances of the same class in the same view, you can prefix the dom_class:

dom_class(post, :edit)   # => "edit_post"
dom_class(Person, :edit) # => "edit_person"

Parameters

record_or_class req
prefix opt = nil
