Django form __init__ doesn't work in userprofileform - django

Question

I'm stuck with the initialization of my userprofileform in the post method of a CBV and the instance receive a None object from the call to super()...
the model is quite standard : a user and his profile; the uerprofile model has an user attribute (onetoone)
models.py
[...]
class User(AbstractUser):
"""User model."""
username = None
email = models.EmailField(_('email address'), unique=True)
first_name = models.CharField(_('first name'), unique=False, max_length=100)
last_name = models.CharField(_('last name'), unique=False, max_length=100)
USERNAME_FIELD = 'email'
REQUIRED_FIELDS = []
class UserProfile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
phone = models.CharField(max_length=15,null=True)
website = models.URLField(blank=True, null=True) upload_to=PathAndRename("avatars/"))
photo = models.ForeignKey(Photo, null=True, on_delete=models.PROTECT)
organization = models.CharField(_('organization'), null=True,unique=False, max_length=100)
city = models.CharField(_('city'), unique=False, max_length=100, null=True)
country = CountryField(blank_label=_('select country'), null=True)
subscribe_newsletter = models.BooleanField(default=False)
language = models.CharField(max_length=10,
choices=settings.LANGUAGES,
default=settings.LANGUAGE_CODE)
User.profile = property(lambda u: UserProfile.objects.get_or_create(user=u)[0])
#receiver(post_save, sender=User)
def create_user_profile(sender, instance, created, **kwargs):
if created:
UserProfile.objects.create(user=instance)
def save(self, *args,**kwargs):
#import ipdb; ipdb.set_trace()
self.city=(self.city or '').lower()
self.organization=(self.organization or '').lower()
self.website=(self.website or '').lower()
super(UserProfile, self).save(*args,**kwargs)
self.user.save()

class UserProfileForm(forms.ModelForm):
class Meta:
model = UserProfile
fields = ('first_name', 'last_name', 'phone', 'website','city','country','organization','subscribe_newsletter')
def __init__(self, *args, **kwargs):
user = kwargs.pop('user',None)
super(UserProfileForm, self).__init__(*args, **kwargs)
try:
self.instance.user=user

pass

def __init__(self,*args,**kwargs):
self.context={}
super().__init__()

profile_form = UserProfileForm(instance=request.user.profile, prefix='profile')
self.context['profile_form']=profile_form
return render(request,'account/profile.html', self.context)
def post(self,request):
#import ipdb; ipdb.set_trace()
if request.POST.get('action',)=='profile':
profile_form = UserProfileForm(request.POST, user=request.user, prefix='profile')
if profile_form.is_valid():
profile_form.save()
info={'title':_('PROFILE SAVED !'),'desc':_('your profile has been successfully updated')}
self.context['infos']=[info]
return render(request,'info.html', self.context)
else:
self.context['errors']=get_form_errors_list(profile_form.errors)
elif request.POST.get('action',)=='avatar':
pass
self.context['profile_form']=profile_form
return render(request,'account/profile.html', self.context)
[...]
The error occurs in the post method of the view when I affect UserProfileForm to profile_form. The debug toolbar return "UserProfile has no user".
The init method of UserProfileForm works with the get method of the view (the instance is set whith the user.profile) but the instance is not given while posting (throwing user.profile would be nonsense as the data are contained in the resquest.POST)...
