Ruby on Rails remote create form with popup show partial

Question

I'm a RoR junior and I'm making online shop app, so:

• on the show view of product I have remote form for @line_item
• in the show action of products_controller I have @line_item = LineItem.new
• I have create.js.erb file in views/line_items

• My create action of line_items_controller looks like this:

  respond_to do |format| format.js { } end

QUESTION: How to make a popup window with line_item's details information appearing when line item's create form is submitted?

Answer 1

You don't need that line in the controller there - all you need is to trigger the display of a popup inside your create.js.erb. That js file will be rendered by convention after executing the create controller method because it is an asynchronous call.
