User has no person.

First question. A one to many relationship between the django User model and some model is allowed right?

Now the main question. I have a couple of models all related to the user model. It just takes in user information and renders the information specifically to the user in the templates. When i tried to submit the form i get a error User has no person. Here is the models and view logic

            from django.db import models
            from django.contrib.auth.models import User

            class Person(models.Model):
                user = models.OneToOneField(User, on_delete=models.CASCADE)
                first_name = models.CharField(max_length=50)
                last_name = models.CharField(max_length=50)
                display_picture = models.ImageField(default='default.png', upload_to='display_pictures') 
                #change default jpeg#

                def __str__(self):
                    return f'{self.user.username} \'s info'
            class Occupation(models.Model):
                user = models.OneToOneField(User, on_delete = models.CASCADE)
                occupation = models.CharField(max_length = 100)

                def __str__(self):
                    return f'{self.user.username} \'s occupation'

            class Skills(models.Model):
                occupation = models.ForeignKey(Occupation, on_delete=models.CASCADE)
                skills = models.CharField(max_length = 100, blank=True)

                def __str__(self):
                    return f'{self.occupation} \'s skillset'

            class WorkExp(models.Model):
                user = models.ForeignKey(User, on_delete=models.CASCADE, blank=True)
                company = models.CharField(max_length = 200, blank=True)
                started = models.IntegerField(null=True, blank=True)
                left = models.IntegerField(null=True, blank=True)
                position = models.CharField(max_length = 200, blank=True)

                def __str__(self):
                    return f'{self.user.username} \'s work experiences'

            class AcadExp(models.Model):  
                user = models.ForeignKey(User, on_delete=models.CASCADE, blank=True)
                education = models.CharField(max_length = 30, blank=True)

                def __str__(self):
                    return f'{self.user.username} \'s academic experiences'

            class Contact(models.Model):
                user = models.OneToOneField(User, on_delete=models.CASCADE, blank=True)
                cell = models.IntegerField()
                twitter = models.CharField(max_length = 100)
                instagram = models.CharField(max_length = 100)
                linkedin = models.CharField(max_length=100)

                def __str__(self):
                    return f'{self.user.username} \'s contact information'


            def portfolio_form(request):
                SkillsFormSet = modelformset_factory(Skills, form=SkillsForm) 
                WorkExpFormSet = modelformset_factory(WorkExp, form=WorkExpForm)
                AcadExpFormSet = modelformset_factory(AcadExp, form=AcadExpForm)
                if request.method == 'POST':
                    person_form = PersonForm(request.POST, request.FILES, instance=request.user.person)
                    occupation_form = OccupationForm(request.POST, instance=request.user.occupation)
                    skillset = SkillsFormSet(request.POST, prefix='skills', queryset=Skills.objects.filter(
                    workexpset = WorkExpFormSet(request.POST, prefix='work-exp', queryset=WorkExp.objects.filter(user=request.user).last())

                    if person_form.is_valid() and occupation_form.is_valid() and skillset.is_valid() and workexpset.is_valid() and acadexpset.is_valid() and contact_form.is_valid():
                        instances =
                        for instance in instances:

                        instances =
                        for instance in instances:

                        instances =
                        for instance in instances:


                    person_form = PersonForm()
                    occupation_form = OccupationForm()
                    skillset = SkillsFormSet(prefix='skill',queryset=Skills.objects.none())
                    workexpset = WorkExpFormSet(prefix='workexp', queryset=WorkExp.objects.none())
                    acadexpset = AcadExpFormSet(prefix='acadexp', queryset=AcadExp.objects.none())
                    contact_form = ContactForm()

                context = {
                    'person_form'     : person_form,
                    'occupation_form' : occupation_form,

                return render(request, 'portfolio/portfolio_form.html', context)

I’m guessing the actual error is flagging this line:

If you are submitting this form to create the Person object, then you will get this error, because your instance parameter is referencing request.user.person - but the object being referenced here hasn’t been created yet.

When you are populating a form from a POST, you only need to supply the instance parameter if there are values you need to populate in that form that might not have been supplied in the request. In the general case, where a form completely describes an object, you don’t want to supply that parameter.

(Note: This holds true for your other forms as well - request.user.whatever isn’t going to work if those referenced objects don’t exist yet.)
