MongoEngine
一、安装
pip install mongoengine
二、基础环境设置
1，NSTALLED_APPS 中加入mongoengine应用
INSTALLED_APPS = (
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'magazines',
'mongoengine',
)
2， 设置mongo数据库
MONGODB_DATABASES = {
"default": {
"name": "test",
"host": '127.0.0.1',
"tz_aware": True, # 设置时区
},
}
3，修改数据库默认选项
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.dummy',
# 'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
}
}
4，连接数据库
from maongoengine import connect
connect('Magazines', host='127.0.0.1', port=27017)
5，创建models
import datetime
from mongoengine import *
class Users(Document):
meta = {
'collection':'user_data', # 集合名称
}
# 设置数据库字段属性
user_id = SequenceField(required=True, primary_key=True) # 主键
user_name = StringField() # 字符串类型
user_pwd = StringField()
user_date = DateTimeField(default=datetime.datetime.now()) # 日期类型
user_real_name = StringField()
user_gender = StringField()
user_tel = StringField()
user_uuid = StringField()
三、数据的增、删、改、查
1，增
from models import Users
users = Users()
users.user_name = 'Kuture'
users.user_pwd = 'Password'
users.user_real_name = 'Mr.Li'
users.user_gender = 'male'
users.user_tel = '000000'
users.user_uuid = 'abcdefg'
users.save()
2，删
from models import Users
users = Users()
users.delete(user_name='Kuture')
users.save()
3，改
from models import Users
users = Users()
users.update(user_name='Kuture') = 'Austin.Kuture'
users.save()
4，查
users = Users.objects(user_name='Kuture)[0]
myname = users.user_name
