dom_id(record, prefix = nil)
Instance Public methods
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 ânew_â instead.
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" dom_id(Post.new, :custom) # => "custom_post"
