django如何让多app共存

#如何实现这样的功能呢? 让多个app 集合在一个apps的目录下呢?

import os
import sys
# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
sys.path.insert(0,os.path.join(BASE_DIR,'apps'))

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'user', #用户模块
    'goods',    #商品模块
    'cart', #购物车模块
    'order',    #订单模块
]

如何在项目内新建一个app模块呢?

　　pycharm 内找到 Tools ------  Run manage.py Task  点击触发运行   输入: startapp   + "app名字" 即可

 

#其次做url分发:

from django.conf.urls import url,include
from django.contrib import admin

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^user/', include('user.urls',namespace='user')),
    url(r'^cart/', include('cart.urls',namespace='cart')),
    url(r'^order/', include('order.urls',namespace='order')),
    url(r'^', include('goods.urls',namespace='goods')),
]

# 注意有多个app共存的话, 模板层渲染会出问题, 需要在settings做配置,配置如下

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR, 'templates')]
        ,
        'APP_DIRS': True,
