Do you have to use an activeRecord object for div\_for?  
Perhaps I’m taking the wrong approach for “dynamic” divs

so far my education:

1. id= , is fine for just one div and prototype activity in an RJS (I  
got this to work)
2. class= , another option, but I don’t see how it can be used
3. div\_for , a helper that uses ActiveRecord objects to come up with  
multiple divs

Below: code that is my best guess for how to proceed, but it doesn’t do  
everything it is supposed to do:

The class will not work for a rjs call… html class elements are not  
unique by design so that is not a good idea anywho…

Here is a good description for div\_for  
[http://apidock.com/rails/ActionView/Helpers/RecordTagHelper/div\_for](http://apidock.com/rails/ActionView/Helpers/RecordTagHelper/div_for)

It’s just a way to create a div that has something todo with the  
record that you have. So if you have a @user object with id of 1 you  
would get id=“user\_1” for the div.
