Django saving models in different databases

I am new to Django. I have two apps created in my project:

python3 manage.py startapp app1
python3 manage.py startapp app1

I am using Mysql as DB and I want that each app should use different schemas.

I try to follow the steps described here: Sharing (mysql) database between apps Django with Database routers

So in settings.py I defined 2 MySql schemas and keep default schema and add the add the DATABASE_ROUTERS.

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'app1',
    'app2',
]

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
    },
    'mydb1':{
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'APP1DB',
        'USER': 'user1',
        'PASSWORD': '****',
        'HOST': 'localhost',   # Or an IP Address that your DB is hosted on
        'PORT': '3306',
    },
    'mydb2':{
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'APP2DB',
        'USER': 'user1',
        'PASSWORD': '****',
        'HOST': 'localhost',   # Or an IP Address that your DB is hosted on
        'PORT': '3306',
    },
}

DATABASE_ROUTERS = ['app1.dbRouter.App1DBRouter', 'app2.dbRouter.App2DBRouter']

Additional files: app1/models1.py

from django.db import models

# Create your models here.

class Model1(models.Model):
    name = models.CharField(max_length=100)

app2/models2.py

from django.db import models

# Create your models here.

class Model2(models.Model):
    name = models.CharField(max_length=100)

And files: app1/dbRouter.py

class App1DBRouter(object):

    def db_for_read(self,model, **hints):
        if model._meta.app_label == 'app1':
            return 'mydb1'
        return None

    def db_for_write(self,model, **hints):
        if model._meta.app_label == 'app1':
            return 'mydb1'
        return None

    def allow_relation(self,obj1, obj2, **hints):
        if obj1._meta.app_label == 'app1' and \
           obj2._meta.app_label == 'app1':
           return True
        return None

    def allow_syncdb(self,db, model):
        if db == 'mydb1':
            if model._meta.app_label == 'app1':
                return True
        elif model._meta.app_label == 'app1':
            return False
        return None

app2/dbRouter.py:

class App2DBRouter(object):

    def db_for_read(self,model, **hints):
        if model._meta.app_label == 'app2':
            return 'mydb2'
        return None

    def db_for_write(self,model, **hints):
        if model._meta.app_label == 'app2':
            return 'mydb2'
        return None

    def allow_relation(self,obj1, obj2, **hints):
        if obj1._meta.app_label == 'app2' and \
           obj2._meta.app_label == 'app2':
           return True
        return None

    def allow_syncdb(self,db, model):
        if db == 'mydb2':
            if model._meta.app_label == 'app2':
                return True
        elif model._meta.app_label == 'app2':
            return False
        return None

After this I expect that when I run commands makemigrations and migrate I would get 2 different tables in 2 different schemas? So:

$ python3 manage.py makemigrations
Migrations for 'app1':
  app1/migrations/0001_initial.py
    - Create model Model1
Migrations for 'app2':
  app2/migrations/0001_initial.py
    - Create model Model2


$ python3 manage.py migrate
Operations to perform:
  Apply all migrations: admin, app1, app2, auth, contenttypes, sessions
Running migrations:
  Applying contenttypes.0001_initial... OK
  ...
  Applying sessions.0001_initial... OK

But there are no tables created except django_migrations in both schemas.
If I use command:

$ python3 manage.py migrate --database=mydb1

then both model tables are created in the APP1DB.

mysql> SHOW TABLES;
+----------------------------+
| Tables_in_APP1DB           |
+----------------------------+
| app1_model1                |
| app2_model2                |
| auth_group                 |

So how to solve this?
