Django测试失败

Question

我在运行Django单元测试时遇到了一个错误，这种情况我以前没有遇到过，今天下午一直在网上查找解决办法。

在终端运行django manage.py test后，我收到了这个错误：

Error: Database test_unconvention couldn't be flushed. Possible reasons:
  * The database isn't running or isn't configured correctly.
  * At least one of the expected database tables doesn't exist.
  * The SQL was invalid.
Hint: Look at the output of 'django-admin.py sqlflush'. That's the SQL this command wasn't able to run.
The full error: (1146, "Table 'test_unconvention.media_image' doesn't exist")

在运行django-admin.py sqlflush时，media_images表被引用，并且在我运行django manage.py syncdb时没有问题。

这是看起来有问题的Image模型：

from django.db import models
from django.contrib.contenttypes.models import ContentType
from django.contrib.contenttypes import generic

class Image(models.Model):
  local_image = models.ImageField(upload_to="uploads/%Y/%m/%d/", height_field="height", width_field="width", max_length=255, null=True, blank=True)
  remote_image = models.CharField(editable=False, max_length=255, null=True, blank=True)
  thirdparty_page = models.CharField(editable=False, max_length=255, blank=True, null=True)
  size = models.CharField(editable=False, max_length=25, blank=True, null=True)
  content_type = models.ForeignKey(ContentType)
  object_id = models.PositiveIntegerField()
  content_object = generic.GenericForeignKey('content_type', 'object_id')
  height = models.PositiveIntegerField(editable=False, blank=True, null=True)
  width = models.PositiveIntegerField(editable=False, blank=True, null=True)
  created_at = models.DateTimeField(editable=False, auto_now_add=True)
  updated_at = models.DateTimeField(editable=False, auto_now=True)

  def __unicode__(self):
    if self.local_image:
      return self.local_image.name
    else:
      return self.remote_image

非常感谢任何帮助，如果需要我提供更多信息，请告诉我！

Answer 1

试试运行 python manage.py syncdb，然后再返回去。

解决方案：确保你在 INSTALLED_APPS 中明确列出子模块（比如 common.media），而不仅仅是父模块（比如 common）。这样可以确保模型被正确识别，测试才能顺利运行。
