Missing Template Error on render_to_string - Rails 3.2.2

Rails
1

Hi,

I’m trying to execute some javascript in the browser after completing
my create action in the controller. Here’s how I’m doing it:

In my controller:
def create
# exectue some code
js = render_to_string(:layout => false, :template =>
“planned_meals/meal.js.coffee.erb”)
render :js => js
end

Two questions:

  1. Am I going about it the right way? Should I be rendering the js
    differently?

  2. WIth this implementation, everything works great, but I’m getting
    the following deprecation warning:
    “DEPRECATION WARNING: Passing a template handler in the template name
    is deprecated. You can simply remove the handler name or pass
    render :handlers => [:erb] instead.”
    However, if I change the render_to_string call to this:

render_to_string(:layout => false, :template => “planned_meals/
meal”, :format => [:js], :handlers => [:coffee, :erb])

Then I get a missing template error. I’m not sure how to get around
the deprecation warning.

Thanks for all your help,
Nick
