How can I create a unique dom identifier for an html tag from a model

Question

I have an index with multiple rows for items that have multiple attributes. I would like to update the contents of the items attribute with ajax, so I need a unique dom identifier. Is there a helper method? Now I am doing the following:

<span id="<%= item.id.to_s + "_on_storage"%>">

Answer 1

you can use

 dom_id(item) 

What is the ActiveRecord method for generating DOM identifiers.

Answer 2

It’s also good practice to use HTML5 data attributes:

 <span data-item-id="<%= item.id %>">
