Error migrate table model users

Using Django Using the ORM
1

Hello,

In my app, I also had an app called user to separate the database of users from the database of records. These databases were called from the settings.py of the main app through a router

I am currently modifying this action and I want to create my own model for the user table and that is where I find the problem.

I get the error

django.core.exceptions.ImproperlyConfigured: settings.DATABASES is improperly configured. Please supply the ENGINE value. Check settings documentation for more details.

I think it’s because I left the default database empty in the settings.py file, but I never had this problem before.

Next I show my files.

db_routers.py

class AuthRouter:

    router_app_labels = {'auth', 'contenttypes', 'sessions', 'admin'}

    def db_for_read(self, model, **hints):
        if model._meta.app_label in self.router_app_labels:
            return 'users_db'
        return None

    def db_for_write(self, model, **hints):
        if model._meta.app_label in self.router_app_labels:
            return 'users_db'
        return None
    
    def allow_relation(self, obj1, obj2, **hints):
        if(
            obj1._meta.app_label in self.router_app_labels or
            obj2._meta.app_label in self.router_app_labels
        ):
            return True
        return None
    
    def allow_migrate(self, db, app_label, model_name=None, **hints):
        if app_label in self.router_app_labels:
            return db == 'users_db'
        return None
    

class IntranetReclamacionesRouter:

    def db_for_read(self, model, **hints):
        if model._meta.app_label == 'reclamaciones':
            return 'intranet_db'
        return None
    
    def db_for_write(self, model, **hints):
        if model._meta.app_label == 'reclamaciones':
            return 'intranet_db'
        return None
    
    def allow_relation(self, obj1, obj2, **hints):
        if (
            obj1._meta.app_label == 'reclamaciones' or 
            obj2._meta.app_label == 'reclamaciones'
        ):
            return True
        return None
    
    def allow_migrate(self, db, app_label, model_name=None, **hints):
        if app_label == 'reclamaciones':
            return db == 'intranet_db'
        return None

Setting.py

DATABASES = {
    'default': {},
    'users_db': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'users',
        'USER': '',
        'PASSWORD': '',
        'HOST': 'xxxxxxx',
        'PORT': '3306' 
    },
    'intranet_db': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'intranet',
        'USER': '',
        'PASSWORD': '',
        'HOST': 'xxxxxxx,
        'PORT': '3306' 
    }
}

DATABASE_ROUTERS = ['routers.db_routers.AuthRouter','routers.db_routers.IntranetReclamacionesRouter']

Any idea what could happen?
Thank you

Yes, for future reference for anyone reading this thread, the docs for DATABASES state:

The DATABASES setting must configure a default database; any number of additional databases may also be specified.
