Rails Rendering a partial within JSON

Question

I am trying to render a partial inside a JSON file so that I can use it via AJAX. Currently in my JSON file I have:

<% self.formats = [\"html\"]%>
{
   \"h

You need to change your controller. In the respond_to part you need to add json rendering. Like this:

respond_to do |format|
     format.json { render :json => @instancevar }
     ....
     ...
     ..
end

Then you can simply add .json to your url and you will receive the data formated as json. What you might need to do is disabeling the JSON root hich is automaticly added by default. Just add this line to your environment (development.rb, production.rb,...) configuration:

config.active_record.include_root_in_json = false

This is important when you are parsing the json.
