how to migrate just specific table in django? - django

Question

I tried multiple databases in django. So, I set databases like that
# settings.py
DATABASE_ROUTERS = [
'stage1.routers.MultiDBRouter',
]
DATABASE_APPS_MAPPING = {
'stage1': 'stage1',
}
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': BASE_DIR / 'db.sqlite3',
},
'stage1': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'stage1',
'HOST': 'localhost',
'USER': 'root',
'PASSWORD': '######',
'PORT': 3306,
'CHARSET': 'utf8mb4',
},
}
# stage1.routers.py
class MultiDBRouter(object):
def __init__(self):
self.model_list = ['stage1']
def db_for_read(self, model, **hints):
if model._meta.app_label in self.model_list:
return model._meta.app_label
return None
def db_for_write(self, model, **hints):
if model._meta.app_label == 'stage1':
return 'stage1'
return None
def allow_relation(self, obj1, obj2, **hints):
if (obj1._meta.app_label in self.model_list or obj2._meta.app_label in self.model_list):
return True
return None
def allow_migrate(self, db, app_label, model_name=None, **hints):
if app_label == 'stage1':
return db == 'stage1'
return None
# stage1.models.py
from django.db import models
class Room(models.Model):
name = models.CharField(max_length=100)
sort = models.CharField(max_length=100)
class Meta:
app_label = "stage1"
I did manage.py migrate --database=stage1 and it worked. But there are something wrong I didn't intend.
I just wanted stage1 database has only one table room. But it has all tables that are basically set like auth_group, django_session ...
How can I do to make only one table room in stage1 database?
Please help me.
