#7750: TextField in unique_together

I get this exception:
{{{
_mysql_exceptions.OperationalError: (1170, "BLOB/TEXT column 'text' used
in key specification without a key length")
}}}
I'm not quite sure about what's the right thing to do. Apparently a text
field can't be used in key combinations in MySQL and probably neither in
other SQL flavors. So maybe Django should raise an exception and/or the
documentation should include which kinds of fields that are valid for the
unique_together meta attribute.
An example could be:
{{{
class Messages(models.model)
subject = models.CharField(max_length=20)
msg = models.TextField
class Meta:
unique_together = ("subject", "msg")
}}}
