Examples

from pymongolite import MongoClient

with MongoClient(dirpath="~/my_db_dir", database="my_db") as client:
    db = client.get_default_database()
    collection = db.get_collection("users")

    collection.insert_one({"name": "yoyo"})
    collection.update_one({"name": "yoyo"}, {"$set": {"age": 20}})
    user = collection.find_one({"age": 20})
    print(user) # -> {"_id": ObjectId(...), "name": "yoyo", "age": 20}

from pymongolite import MongoClient

client = MongoClient(dirpath="~/my_db_dir", database="my_db")

db = client.get_default_database()
collection = db.get_collection("users")

collection.insert_one({"name": "yoyo"})
collection.update_one({"name": "yoyo"}, {"$set": {"age": 20}})
user = collection.find_one({"age": 20})
print(user) # -> {"_id": ObjectId(...), "name": "yoyo", "age": 20}

client.close()

Indexes

from pymongolite import MongoClient

client = MongoClient(dirpath="~/my_db_dir", database="my_db")

db = client.get_default_database()
collection = db.get_collection("users")

# Make query with name faster
collection.create_index({"name": 1})

collection.insert_one({"name": "yoyo"})
collection.update_one({"name": "yoyo"}, {"$set": {"age": 20}})
user = collection.find_one({"age": 20})
print(user) # -> {"_id": ObjectId(...), "name": "yoyo", "age": 20}

indexes = collection.get_indexes()
print(indexes)  # -> [{'id': UUID('8bb4cac8-ae52-4fff-9e69-9f36a99956cd'), 'field': 'age', 'type': 1, 'size': 1}]

client.close()
