Firestore Collections
Simple Firestore collection definitions and queries using pydantic schemas and Firestore query API.
A quick and easy way to make use of the NoSQL document database solution Firestore available in Google Cloud Platform (GCP).
Requirements
- Python 3.6+
- GCP project with Firestore enabled
Features
- Schema definition and validation: Define collection schemas using
pydanticand built-in type hinting (typing). - Automatic IDs: Automatic ID generation using 12-byte hexadecimal (
bson.ObjectId). - Simple queries: Query collections using a simple interface.
- Auxiliary timestamps: Automatically added timestamps to objects like
created_atandupdated_at.
Example
Define users collection and perform different queries:
from typing import Optional
from pydantic import EmailStr, SecretStr
from firestore_collections import Collection, Schema
class User(Schema):
__collection_name__ = 'users'
__unique_keys__ = ['email']
email: EmailStr
full_name: str = None
password: Optional[SecretStr]
# Initialize firestore collection
collection = Collection(schema=User)
# Initialize user object
user = User(
email='john@doe.com',
full_name='John')
# Insert
user = collection.insert(user)
# Get object from db
user = collection.get(user.id)
# Update
user.full_name = 'John Doe'
collection.update(user)
# Get by attribute
user = collection.get_by_attribute('email', 'john@doe.com')
# Get all objects
users = collection.get_all()
# Delete object
collection.delete(id=user.id)
