What's this?

dom_id(record, prefix = nil) public

The DOM id convention is to use the singular form of an object or class with the id following an underscore. If no id is found, prefix with "new_" instead. Examples:

  dom_id(Post.find(45))       # => "post_45"
  dom_id(Post.new)            # => "new_post"

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

  dom_id(Post.find(45), :edit) # => "edit_post_45"
