A simple Django app to automatically filter all model's queryset by the tenant ID.

All models are required to define a foreign key field pointing to the Tenant model and use the Tenant Filter Manager.

Mandatory settings:

TENANT_FILTER = {
    'TENANT_FK_NAME': 'tenant',
    'TENANT_MODEL': 'my_app.models.Tenant',
    'TENANT_USER_MODEL': 'my_app.models.TenantUser',
    'MODEL_EXCEPTIONS': ( )
}

Where my_app.models.py is:

from django.contrib.auth.models import User
from django.db import models
from tenant_filter.models import TenantFilterManager

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

class TenantUser(models.Model):
    user = models.OneToOneField(User)
    tenant = models.ForeignKey(Tenant)
    objects = TenantFilterManager()

class OtherModel(models.Model):
    tenant = models.ForeignKey(Tenant)
    objects = TenantFilterManager()
