I got a schema which Contains 1000 tables,and many of them I don't need, how can I just inspectdb the just tables that I need?
You can do it in the python console, or in *.py file:
from django.core.management.commands.inspectdb import Command
from django.conf import settings
from your_project_dir.settings import DATABASES # replace `your_project_dir`
settings.configure()
settings.DATABASES = DATABASES
Command().execute(table_name_filter=lambda table_name: table_name in ('table_what_you_need_1', 'table_what_you_need_2', ), database='default')
