How do I require an inline in the Django Admin?

Question

I have the following admin setup so that I can add/edit a user and their profile at the same time.

class ProfileInline(admin.StackedInline):
    \"\"\"

You need to set min_num in inline and validate_min in formset.

https://docs.djangoproject.com/en/1.8/topics/forms/formsets/#validate-min

class SomeInline(admin.TabularInline):
    ...
    min_num = 1

    def get_formset(self, request, obj=None, **kwargs):
        formset = super().get_formset(request, obj=None, **kwargs)
        formset.validate_min = True
        return formset
