In my case, with Django 2.1 you could do the following

In forms.py

class ObjectAddForm(forms.ModelForm):

    class Meta:
        model = Object
        exclude = []

class ObjectChangeForm(forms.ModelForm):
    class Meta:
        model = Object
        exclude = []

And then in the admin.py

from your.app import ObjectAddForm, ObjectChangeForm

class ObjectAdmin(admin.ModelAdmin):
    ....
    def get_form(self, request, obj=None, **kwargs):
        if obj is None: 
            kwargs['form'] = ObjectAddForm
        else:
            kwargs['form'] = ObjectChangeForm
        return super().get_form(request, obj, **kwargs)
