Question

I am experiencing an error running django unit tests, I’ve not experienced this before, and have been googling it all afternoon.

I am getting this error in terminal after running django manage.py test:

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")

The media_images table is referenced when running django-admin.py sqlflush and generates ok when I run django manage.py syncdb.

This is the Image model which appears to be troublesome:

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

I appreciate any help, please let me know if I should provide more information!

Solution: Make sure you explicitly define submodules (e.g. common.media) in INSTALLED_APPS and not just the parent module (e.g. common) to make sure that the models are picked up and the test is able to run.
