2 model form with foreign key

[Onur]

below is the my 2 models 

Class Profile(models.MODEL):

       

      first_name = models.Charfield()

      last_name = models.Charfield()

      adress = ..... 

Class Reservation(models.MODEL):

       

       profile = models.ForeignKey(Profile)

       price = models.IntegerField()

       room = models.Charfield()

and I have 2 model form with both models, and my user interface includes all of above those fields,

so What kind of structure do I have to use,  multiple inheritence or just model form(Reservation),

Thank you :)
