Fixed a test that relied on the database to reject invalid data; MySQL doesn't. Refs #17055.

from django.contrib.sites.models import Site

from django.core import management

from django.db import connection

from django.test import TestCase, TransactionTestCase, skipUnlessDBFeature

from .models import Article, Book, Spy, Tag, Visa

        outputs an error message which contains the pk of the object

        that triggered the error.

        """

        # MySQL needs a little prodding to reject invalid data.

        # This won't affect other tests because the database connection

        # is closed at the end of each test.

        if connection.vendor == 'mysql':

            connection.cursor().execute("SET sql_mode = 'TRADITIONAL'")

        new_io = StringIO.StringIO()

        management.call_command('loaddata', 'invalid.json', verbosity=0, stderr=new_io, commit=False)

        output = new_io.getvalue().strip().split('\n')
