Error Msg
创建了一个apps的目录将所有app放入apps文件中, 将apps路径加入sys.path中:
sys.insert(0, os.path.join(BASE_DIR, "apps")) 未改前:
RuntimeError: Model class scanhosts.models.HostLoginInfo doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS. 安装app到install_apps中后, 变成:
django.db.utils.ProgrammingError: (1146, "Table 'db_gold.user_ip_info' doesn't exist")
原因及解决:
1. 没有安装apps, 在setting.py中安装app
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
"users",
"scanhosts",
"details"
]
2. 安装app后, 所有用到app中的模块导入必须使用app.模块名, 不能使用上级目录apps
只能使用:
from scanhosts.utils import login_ssh_do
from scanhosts.models import *
不能使用:
from apps.scanhosts.utils import login_ssh_do
from apps.scanhosts.models import *
3. 如果无法迁移, 可指定迁移model来迁移:
python manage.py makemigrations users scanhosts details
python manage.py migrate
