Example

import firestore_model
from google.firestore import firestore
from filestore_model import Model, Query

# initialize the database connection globally for Firestore Model 
firestore_model.db = firestore.Client()

# Define a data structure for a User
@dataclass
class User(Model):
  first_name:str
  last_name:str
  occupation:str

# Create a new user, pass save = True to automagically save the model object
u1 = User.make(
    first_name='Sonic',
    last_name='Brown',
    occupation='circus dog'
    save=True
  )

# Fetch all users that match a given query
users = User.query([
    ('occupation', 'circus dog'), 
    ('created', '>', 1540776978)
  ]
).get()

# Iterate through the results of the query
for u in users:
  print(u.id, u.created, u.first_name, u.last_name, u.occupation)
