For solution these your problem, create only a model, adding a field
that it represents the table.
And for unique part_number for a table ( type ) use the META option
unique_together
Ex:
class Product(models.Model):
part_number = models.CharField(maxlength=20)
type = models.IntegerField()
...
class META:
unique_together = (("part_number", "type"),)
