42	OneToOneField missing from DATA_TYPES dict	nullstyle@…	Adrian Holovaty	"revision 138 on trunk is missing entries for OneToOneField fields, and so sql generation fails if you have such a field in one of your models.  below is a simple patch to add it to the backends.

the patch fixes sql generation for simple cases such as:

{{{
class Piece(meta.Model):
	fields = (
		meta.CharField('title', 'title', maxlength=256),
		meta.DateTimeField('publishDate', 'date published'),
		meta.ManyToManyField(Category),
	)

class ImagePiece(meta.Model):
	fields = (
		meta.OneToOneField(Piece),		
		meta.FileField('data', 'data', upload_to='pieces'),
	)

}}}

but more complicated models haven't been tested.
