我正在尝试测试我的应用程序但不确定如何在测试环境中配置django-allauth.我正进入(状态:
ImproperlyConfigured: No Facebook app configured: please add a SocialApp using the Django admin
到目前为止,我的方法是tests.py使用实际的Facebook应用程序参数实例化app对象,这是一个在浏览器中本地正常运行的应用程序:
from allauth.socialaccount.models import SocialApp
apper = SocialApp.objects.create(provider=u'facebook',
name=u'fb1', client_id=u'7874132722290502',
secret=u'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX')
apper.sites.create(domain='localhost:8000', name='creyu.org')
我怎样才能运行这些测试？谢谢
我试图清除我的数据库,mydb并重新填充它以查看我的Django模型的一些更改的影响.然后这一切都发生了.我回滚到我早期的模型设置,但我仍然得到错误.
我不是MySQL专家,我不能完全弄清楚问题以及如何处理它; 我尝试使用其他名称创建一个新数据库,但这没有发生.我认为这是我的Django项目创建的问题.
