- Class:
ActionController::RecordIdentifier
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"
