Why do I get this exception?

只有当我通过PyCharm调用unittest时才会发生,不是如果我在shell上使用py.test
It only happens if I call the unittest via PyCharm, not if I use py.test on the shell.
我猜这个$ code> reverse_lazy()在这里不懒,因为它被用在 format_html()
。任何方式拥有一个懒惰的 format_html()
?
I guess reverse_lazy()
is not lazy here, since it gets used in format_html()
. Any way to have a lazy format_html()
?
版本:
- Django 1.8
- Pycharm 5.0.4
推荐答案
由于stacktrace中有url_patterns这样的东西,我假设 DJANGO_SETTINGS_MODULE
设置正确。
Since there are things like url_patterns in the stacktrace, I assume that DJANGO_SETTINGS_MODULE
is set correctly .
但是,在运行其他任何东西之前,您仍然需要调用 django.setup()
。
But, you still need to call django.setup()
before running anything else.
import django
django.setup()
对我来说,这个错误信息消失了。
For me, that made this error message go away.
