dom_class(record_or_class, prefix = nil)
Instance Public methods
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"
