测试 Django 时无法加载夹具

Question

I hope not to make a fool of myself by re-asking this question, but I just can't figure out why my fixtures are not loaded when running test. I am using python 2.7.5 and Django 1.5.3.

I can load my fixtures with python manage.py testserver test_winning_answers , with a location of survey/fixtures/test_winning_answers.json .

Creating test database for alias 'default'...
Installed 13 object(s) from 1 fixture(s)
Validating models...

0 errors found

My test class is doing the correct import:

from django.test import TestCase
class QuestionWinningAnswersTest(TestCase):

    fixtures = ['test_winning_answers.json']
    ...

But when trying to run the test command, it cannot find them:

python manage.py test survey.QuestionWinningAnswersTest -v3
...
Checking '/django/mysite/survey/fixtures' for fixtures...
...
No json fixture 'initial_data' in '/django/mysite/survey/fixtures'.
...
Installed 0 object(s) from 0 fixture(s)
...

I suspect I am missing something obvious, but cannot quite figure it out... any suggestion would be appreciated. Thanks!

Answer 1

It looks like it is trying and failing to find a file called 'initial_data' in '/django/mysite/survey/fixtures' rather than failing to load 'test_winning_answers.json'

Try adding a file called 'initial_data.json' containing just '[]'

Answer 2

I am not sure why, but python manage.py test survey -v3 displays Installed 0 object(s) from 0 fixture(s) .

Following mariodev's recommendations, I looked into django/test/testcases.py , and changed the call_command('loaddata'...) to use verbosity=3 . This clearly showed me that the fixture was properly loaded:

Installing json fixture 'test_winning_answers' from '/django/mysite/survey/fixtures'.
Installed 13 object(s) from 1 fixture(s)

The error that prompted me to look into fixtures loading was actually a typo I had made...

在我的情况下，该应用程序从 INSTALLED_APPS 配置中丢失，以便 Django 查找夹具文件。
