Try this django dynamic db router package. its very simple. install it and configure and use as below.

settings.py

DATABASES = {
'default': {
    'ENGINE': 'django.db.backends.postgresql_psycopg2',
    'NAME': 'my_local_database',
    'USER': 'postgres',
    'PASSWORD': 'my-pass',
    'HOST': '127.0.0.1',
    'PORT': '5432',
},
'master': {
    'ENGINE': 'django.db.backends.postgresql_psycopg2',
    'NAME': 'my_master_database',
    'USER': 'postgres',
    'PASSWORD': 'my-pass',
    'HOST': 'example.com',
    'PORT': '5432',
},
}
DATABASE_ROUTERS = ['dynamic_db_router.DynamicDbRouter']

my_app/views.py

from dynamic_db_router import in_database

from my_app.models import MyModel

def index(request):
     #Picking the DB based on logged in user or you can do this in middile ware as well.
     use_db = "default"
     user = self.request.user
     if user.id == 1:
        use_db = "master"
     # Fetching data from selected databases. 
     with in_database(use_db):
         input = MyModel.objects.filter(field_a="okay")
         output = complex_query_function(input)
