Pass Rails variable through AJAX to partial?

In my Rails app I'm passing a variable to this call: $.get("/parent_submissions/", {submission: d.id}, null, "script");, and I'd like the submission variable to pass through to the partial that is loaded through the controller. The controller action that is routed through /parent_submissions/ is:

def parent
    @submission = Submission.find(params[:submission])
end

That action loads parent.js.erb, which looks like this:

$("body").append( "<%=j render :partial => 'parent', :locals => {:submission => @submission } %>" );

And _parent.html.erb simply looks like this:

<h1>@submission.title</h1>

I checked in my console to see what happens when the get request is called, and it looks like this:

Processing by SubmissionsController#parent as JS
Parameters: {"submission"=>"190", "_"=>"1378443591336"}

This means that the submission value is not null, and is passing the correct submission id through the request correctly. But when the partial is rendered, it just looks like @submission.title.

I assume something is wrong in the controller. Any ideas?

if your going to use the instance variable there is not reason for you to pass it in the locals hash.

So this line:

$("body").append( "<%=j render :partial => 'parent', :locals => {:submission => @submission } %>" );

Could just be:

$("body").append( "<%=j render :partial => 'parent' %>" );

If you want to use the locals your partial needs to be the following:

<h1><%= submission.title %></h1>

You need to change <h1>@submission.title</h1> to <h1><%= @submission.title %></h1> in your partial.
