在admin.py注册这个model时，报了个错：
RuntimeError: Model class apps.goods.models.GoodsType doesn‘t declare an explicit app_label and isn‘t in an application in INSTALLED_APPS.
admin是这样写的：
from django.contrib import admin from apps.goods.models import GoodsType # Register your models here. admin.site.register(GoodsType)
已经把多个应用放到一个文件夹apps，然后在settings也有注册
INSTALLED_APPS = [ ‘django.contrib.admin‘, ‘django.contrib.auth‘, ‘django.contrib.contenttypes‘, ‘django.contrib.sessions‘, ‘django.contrib.messages‘, ‘django.contrib.staticfiles‘, ‘tinymce‘, # 富文本编辑器 ‘user‘, # 用户模块 ‘goods‘, # 商品模块 ‘cart‘, # 购物车模块 ‘order‘, # 订单模块 ]
apps的路径也添加进来了
sys.path.insert(0, os.path.join(BASE_DIR, ‘apps‘))
然后仔细看admin的写法，感觉不太对，把apps去掉就正常了，因为在settings已经添加过这个路径了，所以此时只要从具体的app名导入就好
from django.contrib import admin from goods.models import GoodsType # Register your models here. admin.site.register(GoodsType)
