方式一:是视图里面用using方式可以进行指定到哪个数据读写 from django.shortcuts import render,HttpResponse from app01 import models def index(request): models.UserType.objects.using('db1').create(title='普通用户') # 手动指定去某个数据库取数据 result = models.UserType.objects.all().using('db1') print(result) return HttpResponse('...') 方式二:写配置文件 class Router1: # 指定到某个数据库取数据 def db_for_read(self, model, **hints): """ Attempts to read auth models go to auth_db. """ if model._meta.model_name == 'usertype': return 'db1' else: return 'default' # 指定到某个数据库存数据 def db_for_write(self, model, **hints): """ Attempts to write auth models go to auth_db. """ return 'default' 再写到配置 DATABASES = { 'default': { 'ENGINE': 'django.db.backends.sqlite3', 'NAME': os.path.join(BASE_DIR, 'db.sqlite3'), }, 'db1': { 'ENGINE': 'django.db.backends.sqlite3', 'NAME': os.path.join(BASE_DIR, 'db.sqlite3'), } } DATABASE_ROUTERS = ['db_router.Router1',]
