You can define (in your controller) what the create action is after a successful save, and if you only want to do that for one format, and not the others, you can use the usual method for doing that in a controller, with:
if @foo.create(foo_params) respond_to do |format| if format.js render status: :ok else redirect_to @foo end end else render :new end
Using render status: :ok on success will not let anything else happen, no redirect, nothing changes on screen.
