at GIS3W we developed a suite based on Django for QGIS server , the
code in Open and on Github  (main app is G3W-ADMIN).
The suite parse QGIS project file(at the moment is only for QGIS 2.18)
and stores layer data in to db, alse connection string informations.
With the layer connection we build a Django model on fly for to get data
directly from db ora to write on it.
We developed a 'editing' module but for now is not open, but the core
for build Django model on fly is in the open code .
The suite comunicates with Webgis Client (G3W-CLIENT) with custom api
built with Django Rest Framework.
I hope this can be usefull.
I'm thinking again on django model on fly worflow and his memory
implication, comments and suggestions are welcome.
Have a good weekend.
