我正在使用 Django 框架运行单元测试并收到此错误。
运行实际代码没有这个问题,运行单元测试会即时创建一个测试数据库,所以我怀疑问题出在那里。
抛出错误的代码如下所示
member = Member.objects.get(email=email_address)
模型看起来像
class Member(models.Model):
member_id = models.IntegerField(primary_key=True)
created_on = models.DateTimeField(editable=False, default=datetime.datetime.utcnow())
flags = models.IntegerField(default=0)
email = models.CharField(max_length=150, blank=True)
phone = models.CharField(max_length=150, blank=True)
country_iso = models.CharField(max_length=6, blank=True)
location_id = models.IntegerField(null=True, blank=True)
facebook_uid = models.IntegerField(null=True, blank=True)
utc_offset = models.IntegerField(null=True, blank=True)
tokens = models.CharField(max_length=3000, blank=True)
class Meta:
db_table = u'member'
我看不出有什么奇怪的。
运行测试的用户与运行网站的用户对数据库服务器具有相同的权限
这是运行在 osx 上的 mariadb 上的 django 1.1

我还能在哪里查看哪里出了问题,为什么没有创建此表?
更新 - 问题似乎是在运行单元测试时,用于生成测试数据库的模型来自应用程序内部而不是项目内部。这看起来很奇怪,并且违反了 DRY,因为为了让它工作,我需要在每个应用程序中复制模型文件,而不是在项目中集中复制。
谁能建议如何解决这个问题?
** 更新 2 ** - 项目结构如下所示:
项目结构如下:
/mysite (www.whatever.com)
/application1 (facebook app, handles all urls beginning with /fb)
/application2 (www app, handles everything else in the root dir of the site)
我想将 fb 功能与站点的其余部分分开,但它们共享同一个数据库。我做错了吗?
