Get all table names in a Django app

Question

How to get all table names in a Django app?

I use the following code but it doesn't get the tables created by ManyToManyField

from django.db.models import get_app, get_models
app = get_app(app_name)
for model in get_models(app):
    print model._meta.db_table

Answer 1

from django.db import connection
tables = connection.introspection.table_names()
seen_models = connection.introspection.installed_models(tables)

As seen in the syncdb command for manage.py.

In a comment below, years after the answer above, ThePhi says (I haven't tested it):

from django.apps import apps 
from django.contrib import admin 
from django.contrib.admin.sites import AlreadyRegistered 

app_models = apps.get_app_config('my_app').get_models()

Another user comments that this also works (also untested):

[ m._meta.db_table for c in apps.get_app_configs() for m in c.get_models() ]

And yet another recommends reading this answer:

Django get list of models in application
