python - Is there any method in django to use database without creating models.py file? -

i having database data filled in , want use in new django app. way use data of database in django app.actually don't want make changes in old database , want use data. please suggest me better approach this.

while serching found command-inspectdb can generate model.py file database, issues it does'nt map foreign key in model.py, need rearrange our classes in model.py file , more. searching other alternative.

you access data legacy database using connection.cursor() django.db module.

if have 2 dabases

databases = {     'default': {         'name': 'new_database',         'engine': 'django.db.backends.postgresql_psycopg2',         'user': '',         'password': ''     },     'old': {         'name': 'old_database',         'engine': 'django.db.backends.mysql',         'user': '',         'password': ''     } } 

...

from django.db import connections cursor = connections['old'].cursor() cursor.execute("select...") cursor.fetchall() 

refer docs:

executing custom sql directly

multiple databases

but if want modify data in old database better idea create models.py file , use always. using inspectdb or not you. example cold generate model using inpsectdb in separate temporary project, make dumpdata create json files , upload data active project somehow.
