Django连接MongoDB
作者:互联网
Hello小伙伴们,你们好啊~~ 又是日常get新技能的一天, 今天,咱们来整一下如何使用Django连接MongoDB, 0基础入门,趁着热乎,快上车啦~~。
1. 初始环境
django == 3.2.3 mongoengine == 0.23.1
1.1
需要依赖第三方库:pip install mongoengine
1.2
MongoEngine 是一个文档对象映射器(想想 ORM,但用于文档数据库),用于从 Python 处理 MongoDB。
它使用一个简单的声明式 API,类似于 Django ORM。
2.进入Django进行设置
1.在setting.py里设置DATABASES
from mongoengine import connect
DATABASES = {
'default': {
'ENGINE': None, # 把默认的数据库连接至为None
}
}
connect('dj_mon', host='127.0.0.1', port=27017) # 连接的数据库名称dj_mon
1.2 配置总路由urls.py
"""FirstMongo URL Configuration
The `urlpatterns` list routes URLs to views. For more information please see:
https://docs.djangoproject.com/en/3.2/topics/http/urls/
Examples:
Function views
1. Add an import: from my_app import views
2. Add a URL to urlpatterns: path('', views.home, name='home')
Class-based views
1. Add an import: from other_app.views import Home
2. Add a URL to urlpatterns: path('', Home.as_view(), name='home')
Including another URLconf
1. Import the include() function: from django.urls import include, path
2. Add a URL to urlpatterns: path('blog/', include('blog.urls'))
"""
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path('admin/', admin.site.urls),
path('mon/', include('mon.urls')),
]
2.进入到项目下创建自己的APP
1.1 python manage.py startapp mon
3.在APP里的urls里配置:urls和视图
from . import views
urlpatterns = [
path('Student/', views.get),
]
4.在APP里的models里配置:新建数据模型
import mongoengine
# 类名就是表名,继承基类mongoengine.Document,为普通文档
class StudentModel(mongoengine.Document):
name = mongoengine.StringField(max_length=16)
age = mongoengine.IntField(default=0)
5.在APP里的views里配置:创建视图函数
import mongoengine
from django.http import HttpResponse
from django.shortcuts import render
from .models import StudentModel
from django.views.generic import View
def get(request):
#stu = StudentModel()
#stu.name = '定心'
#stu.age = 12
#stu.save()
if request.method == "GET":
StudentModel.objects.create(name='定心', age=12)
return HttpResponse('hello word')
6.不用makemigrations和migrate,直接就能用,不过必须要先创建好数据库,并且指定字符集
