UpdateView - problem with change model

[Dariusz Mysior]

I have that problem when I change model in view class EditView on PersonalInfo I have response that "Not found personal info that meet your criteria" when I have model = MysiteUser than it is ok but when I change on model = PersonalInfo than it's a problem.

views.py

from django.contrib.messages.views import SuccessMessageMixin
from django.views.generic import TemplateView, UpdateView
from users.models import MysiteUser, PersonalInfo

class ProfileView(TemplateView):
    template_name = 'profile.html'

class EditView(SuccessMessageMixin, UpdateView):
    model = PersonalInfo
    fields = ['age']
    pk_url_kwarg = 'pk'
    template_name = 'update_form.html'
    success_url = '/myprofile/'
    success_message = "Zmiany zostały wprowadzone."

models.py

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

##################################################

class MysiteUser(AbstractUser):
    avatar = models.ImageField(upload_to="avatar")
    #age = models.IntegerField()

    def __str__(self):
        return self.username

class PersonalInfo(models.Model):
    mysiteuser = models.OneToOneField(MysiteUser)
    age = models.IntegerField()

Check the primary key you are passing in the URL while calling the view. Key of PersonalInfo need not to be the same as that of MySiteUser
