django配合mongo使用

Posted 2021-01-21 mswyf

环境

　　django 1.11.16

　　mongoengine 0.16.0

需要安装mongoengine库

　　pip install mongoengine

1.在配置文件中

# settings.py
# Database
# https://docs.djangoproject.com/en/1.11/ref/settings/#databases

DATABASES = {
    ‘default‘: {
        ‘ENGINE‘: None,
        # ‘ENGINE‘: ‘django.db.backends.sqlite3‘,
        # ‘NAME‘: os.path.join(BASE_DIR, ‘db.sqlite3‘),
    }
}

from mongoengine import connect
connect(‘test‘)

2.在models.py中

#models.py
import mongoengine

# Create your models here.


class TextModel(mongoengine.Document):
    name = mongoengine.StringField(max_length=30)
    content = mongoengine.StringField(max_length=255)

3.在views.py中使用

# views.py
from models import TextModel


class Homehtml(object):
    def __init__(self):
        # 实例化模型对象
        self.text = TextModel.objects()

    def create_data(self, request):
        name = request.POST[‘name‘]
        content = request.POST[‘content‘]
        # 插入新数据
        self.text.create(name=name, content=content)
        return HttpResponse(‘SUCESS‘)

    def show_data(self, request):
        # 查询数据库中所有数据
        conlist = self.text.filter()
        return render(request, ‘index_three.html‘, {"conlist": conlist})
    
    def update_data(self, request):
        # 修改数据
        self.text.filter(name=‘test‘).first().update(name=‘testt‘)
        return render(request, ‘index.html‘)

    def dele_data(self, request):
        # 删除数据
        self.text.filter(name=‘test‘).first().delete()
        return render(request, ‘index.html‘)
