rails 3 - How to render a PARTIAL as a Json response

Question

I want to do something like this:

class AttachmentsController < ApplicationController
  def upload
    render :json => { :attachmentPartial => rende         


        

Answer 1

In Rails 6 I think this might be a little different from the accepted answer. I don't think you need to set the underscore in the partial name. This worked for me:

format.json {
  html_content = render_to_string(partial: 'admin/pages/content', locals: { page: @page }, layout: false, formats: [:html])
  render json: { attachmentPartial: html_content }
}
