Training GeoDjango + leaflet with customizations

I would like to receive training on creating a GeoDjango project from scratch (a docker container can be used), there should be a leaflet integration and showing geographic data on the leaflet is important. Geographic data must be read from a postgres/postgis database. The DB system is setup for production and we can create a db for training purposes. We will use QGIS for saving simple models on the database.
