从django.conf.url.defaults导入*
从django.contrib导入管理
从website.views导入hello、类别、产品
从django.conf导入设置
admin.autodiscover（）
urlpatterns=模式（“”，
url（r“^admin/”，包括（admin.site.url）），
url（r'^hello/$，hello），
url（r“^category/$”，类别），
（r“^tinymce/”，包括（'tinymce.url'），
url（r'^product/$，product），

如果设置为.DEBUG：
urlpatterns+=模式（'django.views.static'，
（r'images/（？P.*），'serve'，{'document_root'：settings.MEDIA_root}），
)
编辑：还要使用视图的全名
'product.views.product'
