Answer 1

を試してみてください。

def complete_profile(request): 
    if request.user.is_authenticated(): 
     if request.method == 'POST': 
      form = ProfileForm(request.POST, instance=request.user.profile) 
      if form.is_valid(): 
       #form.instance.user = request.user 
       form.save() 
      return render(request, 'home.html') 
     else: 
      form = ProfileForm() 
      return render(request, 'complete_profile.html', {'form': form}) 
    else: 
     return render(request, 'login.html') 

Answer 2

form = ProfileForm(request.POST,instance=request.user.profile) 
      if form.is_valid(): 
       form.save() 

は、あなたがフォームにインスタンスrequest.user.profileを渡す必要があり、この
