Here's the basic template for adding a recipe. Since it doesn't matter to the template whether we're using a function-based view or a class-based one I'm including it here mostly for the sake of completeness. The jquery. Because we've got multiple formsets on the page we need to give each one a prefix and tell the plugin which forms belong to each formset as explained in the django-dynamic-formset docs.
