plain.models
Model your data and store it in a database.
# app/users/models.py
from plain import models
from plain.passwords.models import PasswordField
class User(models.Model):
email = models.EmailField()
password = PasswordField()
is_admin = models.BooleanField(default=False)
created_at = models.DateTimeField(auto_now_add=True)
def __str__(self):
return self.email
Create, update, and delete instances of your models:
from .models import User
# Create a new user
user = User.objects.create(
email="[email protected]",
password="password",
)
# Update a user
user.email = "[email protected]"
user.save()
# Delete a user
user.delete()
# Query for users
admin_users = User.objects.filter(is_admin=True)
Installation
# app/settings.py

To connect to a database, you can provide a DATABASE_URL environment variable.
DATABASE_URL=postgresql://user:password@localhost:5432/dbname
Or you can manually define the DATABASES setting.
# app/settings.py
DATABASES = {
"default": {
"ENGINE": "plain.models.backends.postgresql",
"NAME": "dbname",
"USER": "user",
"PASSWORD": "password",
"HOST": "localhost",
"PORT": "5432",
}
}
