Python

Let’s say I have these two models (in models.py file):

class FullName (models.Model):
    firstName = models.CharField(max_length=30,null=True,blank=False,unique=True)
    lastName = models.CharField(max_length=30,null=True,blank=False,unique=True)

class Address (models.Model):
    addressLine = models.CharField(max_length=30,null=True,blank=False)
    city = models.CharField(max_length=30,null=True,blank=False)
    state = models.CharField(max_length=30,null=True,blank=False)
    zipcode = models.CharField(max_length=30,null=True,blank=False)

How can I merge these two models in a new model but with the same Id? So it becomes:

class FullName (models.Model):
    firstName = models.CharField(max_length=30,null=True,blank=False,unique=True)
    lastName = models.CharField(max_length=30,null=True,blank=False,unique=True)

class Address (models.Model):
    addressLine = models.CharField(max_length=30,null=True,blank=False)
    city = models.CharField(max_length=30,null=True,blank=False)
    state = models.CharField(max_length=30,null=True,blank=False)
    zipcode = models.CharField(max_length=30,null=True,blank=False)

class AllInformation (models.Model):
    firstName = models.CharField(max_length=30,null=True,blank=False,unique=True)
    lastName = models.CharField(max_length=30,null=True,blank=False,unique=True)
    addressLine = models.CharField(max_length=30,null=True,blank=False)
    city = models.CharField(max_length=30,null=True,blank=False)
    state = models.CharField(max_length=30,null=True,blank=False)
    zipcode = models.CharField(max_length=30,null=True,blank=False)

    (all fields should be inherited from FullName and Address models)

PS: In my views.py file I called a save method like that:

fullNameData = FullName(request.POST)
fullNameData.save()
        and
AddressData = Address(request.POST)
AddressData.save()

Thanks in advance and I really appreciate who answers that because I see that many people having the same problem. I also took a look at the OneToOneField from django docs but I understood nothing to be honest xD

Answer

Solution:

When submitting the FullName form I just do:

data = AllInformation(firstName = request.POST.get("firstname"), lastName = request.POST.get("lastname"))
data.save()

Then in the 2nd function when submitting the Address form, I just do:

AllInformation.objects.filter(firstName=the first name got from FullName Form).update(addressLine = value, city = value, ... )

Hope it helps anyone who is trying to merge two (or more) models in one other model that should contain all of the previous model fields.
