PyMongo 与 Django 的 MongoEngine

使用PyMongo和Django的MongoEngine进行MongoDB数据库操作

python
import pymongo
# 连接MongoDB数据库
client = pymongo.MongoClient('mongodb://localhost:27017/')
db = client['mydatabase']
# 插入数据
collection = db['mycollection']
data = {'name': 'John', 'age': 25}
collection.insert_one(data)
# 查询数据
result = collection.find({'name': 'John'})
for item in result:
    print(item)
# 更新数据
collection.update_one({'name': 'John'}, {'$set': {'age': 26}})
# 删除数据
collection.delete_one({'name': 'John'})

python
from mongoengine import connect, Document, StringField, IntField
# 连接MongoDB数据库
connect('mydatabase')
# 定义数据模型
class Person(Document):
    name = StringField(required=True)
    age = IntField()
# 插入数据
person = Person(name='John', age=25)
person.save()
# 查询数据
result = Person.objects(name='John')
for item in result:
    print(item)
# 更新数据
person.age = 26
person.save()
# 删除数据
person.delete()
