-Model file fields
------------------
-
-For a product loaded from your database, pass ``product.image`` directly to
-``imgproxy_url`` in the controller. Here, ``Product`` is your Django model
-with an optional image field. ``ProductPath`` declares a ``product_id: int``
-path parameter using a Pydantic model. Imports, the Django model, path model,
-and the route are omitted from this snippet:

-   1. Generate a URL only when the file field has an associated file;
-      otherwise return ``None``, serialized as JSON ``null``.
-
-Without the empty-field check, the default source
-resolver raises ``ValueError`` for a field without an associated file.
