MicroMongoEngine

A simple tool to easely map Python Objects to MongoDB Documents and back.

# initialize Documents  
import document  
document.database = <some_mongodb_database>  
  
class User(document.Document):  
  
  _collection = "user" # the collection in which the object will be saved  
  _id_field = "user_id" # the field for a unique identifier for this object  
  
  _marshaled = ["name", "age"] # a filter for json dumps  
  
  user_id: str = None # all fields have to be initialized with None or a default value  
  
  name: str = None  
  age: int = None  
  
  created: datetime = None  
  
# crate a new User  
user = User(  
    user_id="some_id",  
  name="Hans",  
  age=5,  
  created=datetime.utcnow()  
)  
  
# save the object into the collection  
user.save()  
  
# request a user of the collection by its user_id  
user1 = User.get(user_id="some_id")  
user == user1  
  
# request all user with an age of 5  
user_list = User.get_all(age=5)  
  
# get the count of users with age = 5 without loading them  
count = User.count(age=5)  
  
# update a user  
user.age = 6  
user.update()  
  
# or  
user.update_data(age=6)  
  
# delete the user  
  
user.delete()
