@HonzaKral HonzaKral merged commit 0ad7684 into django:master

This test will surely fail on Python 3 (no u prefix). Either use the str_prefix utility in the test, or simply don't use the %r placeholder in the exception.

If you want I can remove %r from exception message.


Fixed in #791 and bfd4a71.
