13. Creating Shop and Domain models

# shop/models.

# Django modules
from django.db import models
from django_tenants import TenantMixin, DomainMixin

# Create your models here.


# MODEL: Shop as client
class Shop(TenantMixin):

  name = models.CharField(max_length=100)

  # Default true, schema will be authomatically 
  # created and synced when it is save
  auto_create_schema = True

  def __str__(self):
    return self.name 


# MODEL: Domain
class Domain(DomainMixin):
  pass 

<<<<<<< HEAD

14. Fixing impor of django_tenants, add TENANT_MODEL and TENANT_DOMAIN_MODEL to settings.py

# Fixing import django_tenants
# Before
from django_tenants import TenantMixin, DomainMixin # do not use this, use bellow

# After fixing
from django_tenants.models import TenantMixin, DomainMixin

# Add TENANT_MODEL and TENANT_DOMAIN_MODEL to settings.py
# NEW
TENANT_MODEL = "shop.Shop"
TENANT_DOMAIN_MODEL = "shop.Domain"

15. Adding middleware to settings.py

MIDDLEWARE = [
    # Must put on the top
    'django_tenants.middleware.main.TenantMainMiddleware', # new    

    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
]

16. Darurat

# shop/models.

# Django modules
from django.db import models
# Fixing this bellow
from django_tenants.models import TenantMixin, DomainMixin


        both modified:   README.md
        both modified:   shop/models.py

17. Split the INSTALLED_APPS

SHARED_APPS = [
    
    # Third party apps

    # django_tenants MUST be placed at 
    # the highest position possible
    'django_tenants',

    # Locals
    'shop.apps.ShopConfig',  

    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
]

TENANT_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
]

INSTALLED_APPS = list(SHARED_APPS) + [
    app for app in TENANT_APPS if app not in SHARED_APPS
]

18. Run migrations

E:\workspace\django-2022\TENANTCY\2022-django-tenant-guide\2022-django-tenant-guide\sweetshop (main)
(django-tenant) λ python manage.py makemigrations
Migrations for 'sweet_shared':
  sweet_shared\migrations\0001_initial.py
    - Create model SweetType
Migrations for 'sweet_tenant':
  sweet_tenant\migrations\0001_initial.py
    - Create model Sweet

# Apply migrations
E:\workspace\django-2022\TENANTCY\2022-django-tenant-guide\2022-django-tenant-guide\sweetshop (main)
(django-tenant) λ python manage.py migrate
