My Django REST API is composed of multiples apps, one app per resource like that:
├── core
│ ├── settings.py
│ ├── urls.py
├── customers
│ ├── models.py
│ ├── serializers.py
│ ├── urls.py
│ └── views.py
├── orders
│ ├── models.py
│ ├── serializers.py
│ ├── urls.py
│ └── views.py
The settings of the app are all in core/settings.py.
How can I tell zappa to deploy each app in a different lambda function and configure API Gateway to handle the routing for each app?
I suggest you add a stage per app in your zappa_settings.json file. Then you can deploy each stage independently.
See the documentation for exact formatting.
