Question

我在运行django单元测试时遇到错误，我之前没有经历过这种情况，并且整个下午都在谷歌搜索。

运行django manage.py test后，我在终端中收到此错误：

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")

运行django-admin.py sqlflush时会引用media_images表，并在运行django manage.py syncdb时生成ok。

这是图像模型，看起来很麻烦：

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

感谢您的帮助，如果我需要提供更多信息，请告诉我们。

Answer 1

解决方案：确保在common.media中明确定义子模块（例如INSTALLED_APPS），而不仅仅是父模块（例如common），以确保模型被拾取并且测试能够运行。

Answer 2

尝试python manage.py syncdb然后返回

Django测试失败
