django.db.utils.OperationalError: 没有这样的表: auth_user

安装后 Django-userena 一个错误
my django version: 1.9.5
我只是在安装 django-userena 一步一步,但是当我携带它时,发生错误,我不知道如何解决它。

./manage.py migrate


如果您的版本 Django 平等的 1.9 或更低,使用


./manage.py syncdb


然后


python manage.py createsuperuser


更多信息

也许它会有所帮助

问题在于这一行:


File "C:\Python27\lib\site-packages\guardian\management\__init__.py", line 33, in create_anonymous_user
User.objects.get/**lookup/



guardian\management\__init__.py

is calling
User

before it is defined.

Why is it called before it is defined?
...well, it is called by
makemigrations

to find out if there are changes in the
db

to define them /the changes that are found/

...so this is a "chicken and egg" problem.

I have the same error with a similar problem but the offending code was my own code /not a library like
guardian

/

My code was like this:


CHAT_BOT_USER, created = User.objects.get_or_create/username='rosty', \ email=settings.EMAIL_HOST_USER/


进攻部分是
User

, 在创建表之前使用
auth_user


只有在存在表时才能运行代码解决了问题。 它不会发生
OperationError

. 你可以学习它
try/except

, 像这样:


from django.db import OperationalError

try:
CHAT_BOT_USER, created = User.objects.get_or_create/username='rosty', email=settings.EMAIL_HOST_USER/

except OperationalError:
CHAT_BOT_USER = None

if created:
CHAT_BOT_USER.set_password/settings.EMAIL_HOST_PASSWORD/
CHAT_BOT_USER.save//


因此,
makemigrations

运行代码
except

, 和
runserver

- 代码
try

.

注意逻辑价值
created

, 您可以使用任何其他方法来避免执行代码。
makemigration

, 这取决于结果
User.objects....

我得到了同样的错误并解决了同样的事情,我检查了上述表是否存在于错误中 connected DB 或不。 但这不是。 再次应用迁移,并运作。


python manage.py migrate

python manage.py makemigrations
