Simple Firestore ORM

Firedom

Simple Firestore ORM for Python.

Installation

pip install firedom

Getting started

Initialize Firedom

from firedom import Firedom


firedom = Firedom(service_account_json_path='your-credentials.json')

Define your models

Create a model for your Firestore collection by inheriting from Model:

from dataclasses import dataclass
from firedom import Firedom


firedom = Firedom(service_account_json_path='your-credentials.json')


@dataclass
class Company(firedom.Model):
    name: str


@dataclass
class User(firedom.Model):
    username: str
    email: int
    country: str
    city: str
    is_active: bool = True
    number_of_pets: int = 0
    company: Company

    class Config:
        # Required: Field to be used as document ID
        document_id_field = 'username'

Manipulate documents

Create

company = Company.collection.create(name='Example Company')

user = User.collection.create(
    username='afuenzalida',
    email='[e-mail]',
    country='Chile',
    city='Santiago',
    company=company,
)

Retrieve

users = User.collection.all()

user = User.collection.get('afuenzalida')

Filter

# All arguments are considered as AND:
users = User.collection.where(
    User.country == 'Chile',
    User.is_active == True,
    User.city.is_in(['Santiago', 'Valparaíso']),
    User.number_of_pets > 1,
)

# You can filter with OR using the | operator:
users = User.collection.where(
    (User.country == 'Chile') |
    (User.country == 'China'),
)

# And you can also filter explicitly with AND using the & operator:
users = User.collection.where(
    (User.city == 'Santiago') &
    (User.number_of_pets == 0),
)

# Full example: Filter by active users from Chile or China:
users = User.collection.where(
    (User.is_active == True) &
    (
        (User.country == 'Chile') |
        (User.country == 'China')
    ),
)

Sort

users = User.collection.where(
    User.country == 'Chile',
).order_by(
    'email',
    desc=True,
)

Update

user = User.collection.get('afuenzalida')
user.country = 'Australia'
user.save()

Delete

user = User.collection.get('afuenzalida')
user.delete()

User.collection.all().delete()
