Subject: Re: passing values from partial to controller

hi,

pass your parameters to your partial like this:
<%=render :partial => 'users/grouprow' ,:collection => @groups%>


and when you want to call the parameters in your partial, you have to call it by the name of your partial so it will be something like this:

grouprow.id
grouprow.name
