I think the problem here is that when you create the superuser, the related
field will not be created.
You should add sistema = models.ForeignKey('Sistema', null=True) or sistema
= models.ForeignKey('Sistema', default=1) where 1 is a placeholder
'Sistema' object that you have created.
I suggest to just use the null method as it designs a better system.
