ManytoManyField refuses to show up when I syncdb

[willy Hakizimana]

when I syncdb and use south schemamigration, I still can't get the ManyToManyField to show up.
what am I doing wrong. Any parameters I can pass to make it work?

Thank you guys


class Products(models.Model):

    #product_id = models.AutoField(primary_key=True)
    hs_number = models.CharField(primary_key=True, max_length=6)
    product_description = models.ManyToManyField(Countries, through='Imports')
