## Overview

Django Address is a reusable Django app for capturing postal addresses, normalizing their components, and storing them as related Country, State, Locality, and Address records. The principal workflow is a user entering an address in a Django form: the widget supplies browser autocomplete, submitted components are converted by the form field, and the model layer persists the address. AddressField also offers a convenient way for other models to reference addresses. Google Maps is an optional browser integration; the example-site view demonstrates form submission and address listing. Core model and example-form implementations were not sampled, so their internal wiring is shown only where documented or evident in the sampled view.

Main entry points: [`address/models.py`](https://github.com/blazikentech/django-address/blob/develop/address/models.py) (Address records), [`example_site/person/views.py`](https://github.com/blazikentech/django-address/blob/develop/example_site/person/views.py) (Example home view), [`address/forms.py`](https://github.com/blazikentech/django-address/blob/develop/address/forms.py) (Address form field), [`address/widgets.py`](https://github.com/blazikentech/django-address/blob/develop/address/widgets.py) (Address widget)
