Rails Render Partial With Json Object

In my rails app I have a javascript callback after the a post is created that polls a processing endpoint to check if an image has finished processing and then updates the view lik

Solution 1:

I was able to get it work by rendering the partial as a string of HTML inside of the json object, similar to what's being done in this question: rails 3 - How to render a PARTIAL as a Json response

I changed the if statement in post_controller.rb to:

if !@post.image_processing?
  data[:partial] = render_to_string(@post)
end

and then in create.js.erb changed the callback to:

$("#js-capture-container").html(data.partial);

very nice, very clean.
