fireorm 0.0.5

Firestore ORM for python.

FireORM

The easiest way to use Firestore with python.

Instalation

pip install fireorm

Example

from fireorm.Models import Model
from fireorm.Fields import TextField

class Salesman(Model):
    name = TextField()
    company = TextField()

s = Salesman()
s.name = 'Jim'
s.save()

# Get Salesman
s = Salesman.collection.get(s.id)
print(s.name) # Jim

Fields

There are 9 types of builtin fields, consistant with Firestore: BooleanField, DateField, ListField, MapField, NullField, ReferenceField, TextField, and NestedModel (which we'll get in a bit).

Each field takes the optional parameters default and required. If the field is not set, it will default to the value of default. If there is no default, the field is not set, and required == True, an Exception will be raised.

Fields Example

class Manager(Model):
	name = TextField(required=True)
	age = NumberField(required=True)
	company = TextField(required=True, default='Dunder Mifflin')
	startedWorkingAt = DateField()

m = Manager(name='Michael Scott') # you can pass in fields or set them later
m.age = 45
m.save() # Success! New doc in collection "manager" as: { name: Michael Scott, age: 45, company: Dunder Mifflin }

m = Manager()
m.name = 'Dwight Schrute'
m.save() # Exception since age is required but not given

You can also add a NestedModel which lets you add a defined class as a Field.

NestedModel Example

class Dog(Model):
	age = NumberField()
	owner = Manager(required=True)

dog = Dog()
dog.age = 3
dog.owner = Manager(name='Robert California', age=59)
dog.save()

Collections

The collection name for a class defaults to the class' name in lowercase. To set the collection name, use the Meta class. You can also specify which fields print when printing the class.

Meta Example

class Student(Model):
	name = TextField()
	school = TextField(required=True, default='UPenn')

	class Meta:
		collection_name = 'students'
		fields_to_print = ['name']

s = Student(name='Amy Gutman')
s.save() # creates a new document in the "students" collection
print(s) # <*Student* key: students/9AJ5DeSvzfD04uqyhhpL, id: 9AJ5DeSvzfD04uqyhhpL, name: Amy Gutman>

You can also inheret classes.

Inheritance Example

class ExchangeStudent(Student):
	originalCountry = TextField(required=True)

	class Meta:
		collection_name = 'exchangeStudents'
		fields_to_print = None # when this is None or does not exist, it prints all fields. When it is [] it only prints the defaults (key and id).

e = ExchangeStudent(originalCountry='UK')
print(e.school) # UPenn
e.save()
print(e) # <*ExchangeStudent* key: exchangeStudents/XbGdMjo9x9166MvZ79Zr, id: XbGdMjo9x9166MvZ79Zr, name: None, originalCountry: UK, school: UPenn>

Queries

You can make queries with the same syntax you would using the Python firebase-admin SDK. But FireORM returns the objects.

Queries Example

managers = Manager.collection.where('name', '==', 'Michael Scott').limit(1).stream()
print(managers) # [<*Manager* key: manager/Z8S75KU2n7QQnIm2cExy, id: Z8S75KU2n7QQnIm2cExy, age: 45, company: Dunder Mifflin, name: Michael Scott, startedWorkingAt: None>]

manager = Manager.collection.get('Z8S75KU2n7QQnIm2cExy')
print(manager) # <*Manager* key: manager/Z8S75KU2n7QQnIm2cExy, id: Z8S75KU2n7QQnIm2cExy, age: 45, company: Dunder Mifflin, name: Michael Scott, startedWorkingAt: None>
