Ruby on Rails

I'm not sure how your form is constructed at the moment. But if you were passing the result of the dragged items back to a meals_controller, you could assign the array of values to `menu_item_ids` and the child menu items would be created and assigned. You'll have to ensure that you whitelist that attribute in a special way:

def meal_params
params.permit(:foo, :bar, :baz, menu_item_ids: [])
end

You'll want to put this (and any other array-shaped parameters) at the end of the list of permitted params, and you have to cast it to an array as I've done here.

If you are sending the form to the menus_controller, then you've got a doubly-nested assignment going on, and you'll probably want to use accepts_nested_parameters_for in your model relationship between menu and meal. I would do that if I was building N number of meals within one menu form. If you're trying to get this going first, I would just save each meal individually first, and then, once it's working at that level, try to further complicate it by nesting forms.
