You need to create a custom widget for this field that lets you autocomplete for the correct record. If you don't want to roll your own: http://django-autocomplete-light.readthedocs.io/

I've used this for its generic relationship support, the M2M autocomplete looks pretty easy and intuitive as well. see video of use here: http://www.youtube.com/watch?v=fJIHiqWKUXI&feature=youtu.be

After reading your comment about needing it outside the admin, I took another look at the django-autocomplete-light library. It provides widgets you can use outside the admin.

from dal import autocomplete
from django import forms

class PersonForm(forms.ModelForm):
    class Meta:
        widgets = {
            'myformfield': autocomplete.ModelSelect2(
                # ...
            ),
        }
