django-导入应用包的搜索路径

创建应用包

 在 settings.py注册和配置urls.py中要按顺序导入包名和应用名

settings.py

INSTALLED_APPS = (
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'apps.user',
    'apps.cart',
    'apps.goods',
    'apps.orders',
)

路由urls.py

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

如果想把apps去掉的话要在配置文件里加入搜索路径

settings.py

import sys

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
# 加入搜索路径
sys.path.insert(0, os.path.join(BASE_DIR, 'apps'))  # 需要导入sys

这样就可以不加apps了

settings.py

INSTALLED_APPS = (
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'user',
    'cart',
    'goods',
    'orders',
)

urls.py

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url(r'^user$', include('user.urls', namespace='user')),  # 用户模块
    url(r'^cart$', include('cart.urls', namespace='cart')),  # 购物车模块
    url(r'^orders$', include('orders.urls', namespace='orders')),  # 订单模块
    url(r'^$', include('goods.urls', namespace='goods')),  # 商品模块

]
