Question

I currently am able to render a partial in JS like so:

$("#cmtList_<%= @commentable.id %>").prepend("<%=escape_javascript(render :partial =>"comments/comment", :locals => {:comment => @comment})%>");

The above works swell for rendering/returning one new comment.

Now I want to reuse that same partial(to stay DRY), but be able to pass an array of comments as @Comments, and have Rails loop through all the @comments records (1 or more) using the same partial, I tried this but it errors:

$("#cmtList_<%= @commentable.id %>").prepend("<%=escape_javascript(render :partial => "comments/comment", :collection => {:comment => @comments})%>");

Any ideas?

Thanks

Try:

$("#cmtList_<%= @commentable.id %>").prepend("<%=escape_javascript(render :partial => "comments/comment", :collection => @comments)%>");

which will look for a local variable “comment”.
