1662	'string' form references in models don't appear to work	Russell Keith-Magee	Russell Keith-Magee	"Michael Radziej <mir@noris.de> reports that the following two models, which use the 'string' form of model reference in Foreign Keys, fail:

Version 1 (back referenced model):
{{{
class Wenga(models.Moldel):
   ...

class Benga(models.Model):
   wenga = ForeignKey(""Wenga"")
}}}

Version 2: Forward referenced model
{{{
class Benga(models.Model):
   wenga=ForeignKey(""Wenga"")

class Wenga(models.Model):
   ...
}}}

Version 2 succeeds syncdb, but fails on model import. Version 1 fails on syncdb with the same error that Version 2 provides during syncdb:
