here my codes:
Models:
class Profile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
avatar = models.ImageField(blank=True)
location = models.CharField(max_length=30, blank=True)
bio = models.TextField(max_length=500, blank=True)
active = models.BooleanField(default=True)
timestamp = models.DateTimeField(auto_now_add=True)
def __str__(self):
return self.user.username
#receiver(post_save, sender=User)
def create_user_profile(sender, instance, created, **kwargs):
if created:
Profile.objects.create(user=instance)
#receiver(post_save, sender=User)
def save_user_profile(sender, instance, **kwargs):
instance.profile.save()
Views:
class RegisterView(CreateView):
template_name = "registration/register.html"
form_class = RegisterForm
success_url = '/'
def dispatch(self, *args, **kwargs):
# if self.request.user.is_authenticated():
# return redirect("/logout")
return super(RegisterView, self).dispatch(*args, **kwargs)
class ProfileUpdateView(UpdateView):
model = Profile
form_class = ProfileForm
template_name = 'profiles/profile-detail-update.html'
success_url = '/'
def get_object(self, **kwargs):
username = self.kwargs.get("username")
if username is None:
raise Http404
return get_object_or_404(User, username__iexact=username)
Forms
class RegisterForm(forms.ModelForm):
password1 = forms.CharField(label='Password', widget=forms.PasswordInput)
password2 = forms.CharField(label='Password confirmation', widget=forms.PasswordInput)
class Meta:
model = User
fields = ('username',)
def clean_password2(self):
password1 = self.cleaned_data.get("password1")
password2 = self.cleaned_data.get("password2")
if password1 and password2 and password1 != password2:
raise forms.ValidationError("Passwords don't match")
return password2
def save(self, commit=True):
user = super(RegisterForm, self).save(commit=True)
user.set_password(self.cleaned_data["password1"])
if commit:
user.save()
return user
class ProfileForm(forms.ModelForm):
class Meta:
model = Profile
fields = ('avatar', 'location', 'bio', 'active',)
URL
url(r'^(?P<username>[\w-]+)/$', ProfileUpdateView.as_view(), name='update'),
Template:
{% extends 'base.html' %}
{% block content %}
<p>name: {{ user.username }}</p>
<p>location: {{ user.profile.location }}</p>
{% if user.profile.avatar %}
<img style="width: 200px" src="{{ user.profile.avatar.url }}"/>
{% endif %}
<hr/>
{% include 'snippets/form.html' %}
{% endblock %}
Included snippet:
<div class="form pt-2">
{% if form.errors.non_field_errors %}
{{ form.errors.non_field_errors }}
{% endif %}
<form method='POST' action='' enctype='multipart/form-data'> {% csrf_token %}
{{ form.as_p }}
<button class='btn btn-success' type='submit'>Save</button>
<button onclick="window.history.back();" class="btn btn-danger" type="button">Go back</button>
</form>
</div>
SOS.

In your ProfileUpdateView you are passing an User instance to the form, instead of a Profile instance:
class ProfileUpdateView(UpdateView):
# ...
def get_object(self, **kwargs):
username = self.kwargs.get("username")
if username is None:
raise Http404
return get_object_or_404(Profile, user__username__iexact=username)
