ActiveRecord DOM IDs

The solution—or at least a nice, cheap bandaid that can be applied easily, consists of adding a method to ActiveRecord::Base to help generate these ids without any brainpower involved.

Here’s a very simple implementation that I use in my projects, courtesy of Jamis Buck:



class ActiveRecord::Base
  def dom_id(prefix=nil)
    display_id = new_record? ? "new" : id
    prefix ||= self.class.name.underscore
    prefix != :bare ? "#{prefix.to_s.dasherize}-#{display_id}" : display_id
  end
endSo, you can do stuff like this in your views:

<ul>
<% @entries.each do |entry| %>
  
  • >
    <%= entry.body %>
  
    • 
<% end %>
And stuff like this in your controller:

def remove_entry
  entry = JournalEntry.find(params[:id])
  update_page do |page|
    page[entry.dom_id].remove
  end
end
