Error in django unittest while loading a fixture

I am making unittests for a django app. I need some data in the database for my tests so I am using a json fixture.

I have two fixtures:

  1. for users and it works ok.
  2. for some webpages

The fixture 2 cause the following error:

Problem installing fixture 'C:\Users\luc\Dev\Hg\mnl-adminpub\website\fixtures\website-unittest.json': Traceback (most recent call last):
  File "C:\Python26\lib\site-packages\django\core\management\commands\loaddata.py", line 169, in handle

    cursor.execute(sql, params)
  File "C:\Python26\lib\site-packages\django\db\backends\mysql\base.py", line 86, in execute
    return self.cursor.execute(query, args)
  File "C:\Python26\lib\site-packages\MySQLdb\cursors.py", line 173, in execute
    self.errorhandler(self, exc, value)
  File "C:\Python26\lib\site-packages\MySQLdb\connections.py", line 36, in defaulterrorhandler
    raise errorclass, errorvalue
OperationalError: (1366, "Incorrect string value: '\\xE2\\x80\\xA8<br...' for column 'html' at row 1")

I've created the fixture with dumpdata. I've tested it with loaddata and it works fine. I am using mysql.

Any idea of the possible cause of the problem?

Thanks for your help

You should use TEST_CHARSET, but inside DATABASE config. Like that:

DATABASES = {
      'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'test_sbet',                      
        'USER': 'test_sbet',                      
        'TEST_CHARSET': 'UTF8',
    }
}

If this only happens during testing, I would suspect some of the TEST_ settings, like TEST_CHARSET. Maybe your (regular, not test) db has some non default charset? If so, you need to specify which charset the test database should be set up with.

BTW, If you are using an older (pre 1.2) version, then this should be done using TEST_DATABASE_CHARSET.
