Django Rest Framework 集成 MongoDB 数据库
环境配置
- Django
- django-rest-framework-mongoengine
- djangorestframework
- mongoengine
- pymongo
过程
创建一个新的 Django 项目
在 settings.py 中进行基本的配置
DATABASES = {
'default': {
# 把默认的数据库连接置为 None
'ENGINE': None,
}
}
from mongoengine import connect
DB_MONGO_NAME = 'test'
DB_MONGO_HOST = '127.0.0.1'
DB_MONGO_PORT = 27017
connect(DB_MONGO_NAME, host=DB_MONGO_HOST, port=DB_MONGO_PORT)新建一个 app: polls
python manage.py startapp polls在新建的 app: polls 的 models.py 中新建数据模型
from mongoengine import Document, fields
class Poll(Document):
name = fields.StringField(required=True)
votes = fields.IntField(required=True)在应用中创建一个序列化器
from rest_framework_mongoengine import serializers
from polls import models
class PollSerializer(serializers.DocumentSerializer):
class Meta:
model = models.Poll
fields = '__all__'在视图文件中创建一个视图
from rest_framework_mongoengine.viewsets import ModelViewSet as MongoModelViewSet
from polls import models
from polls import serializers
class PollViewSet(MongoModelViewSet):
""""""
queryset = models.Poll.objects.all()
serializer_class = serializers.PollSerializer配置 URL
- polls/urls.py
from django.conf.urls import url
from polls import views
urlpatterns = [
url(r'^$', views.PollViewSet.as_view())
]- drf_mongo_example/urls.py
from django.contrib import admin
from django.urls import path
from django.conf.urls import include
urlpatterns = [
path('admin/', admin.site.urls),
path('polls/', include('polls.urls')),
]运行并访问
python manage.py runserver
访问 http:127.0.0.1:8000/polls/
