Description (last modified by James Bennett)

i noticed that the methods field__exact and field__iexact match case insensitive on mysql
given you have a field (choices=(('a','small a'),('A','capital a'))) field__exact will always match both choices.

possible solution:
in django.db.backends.mysql.base

OPERATOR_MAPPING = {
    'exact': '= BINARY %s',
    ...
}

oh and will iexact, icontains, istatswith, iendswith all match exactly the same rows anyways?

Has patch: set

This came up in IRC today, when somebody noted that it's resulting in an exception if you do FooModel.objects.get(charfield='foo') and have both 'foo' and 'Foo' in that field (Two rows returned instead of one as expected).
