my views.py

def picturecreator(request): if not request.user.is_authenticated():     return httpresponseredirect(reverse('world:loginrequest'))  if request.method == "post":     form = pictureform(request.post , request.files)     if form.is_valid():         picture = picture(user=request.user)         image = request.files.get('image')         if image:                             picture.image = form.cleaned_data['image']                     description = form.cleaned_data['description']         if description:                             picture.description = form.cleaned_data['description']          if board:                             picture.board = form.cleaned_data['board']         picture.save()         board = whiteboard.objects.get(whiteboard=picture.board)         the_id = board.id     return httpresponseredirect(reverse('world:boat', kwargs={'animal_id': the_id }))     return render(request,'picture.html',{'form':pictureform()}) 

picture.html

<form method="post" enctype="multipart/form-data">     {% csrf_token %} {{ form.as_p }} <input type = "submit" value= "add picture" />  </form> 

pass user in init in form in view must pass user value pictureform(request.user)

class pictureform(forms.modelform):     class meta:         model = picture      def __init__(self, user, *args, **kwargs):         super(pictureform, self).__init__(*args, **kwargs)         self.fields['whiteboard'].queryset = whiteboard.objects.filter(user=user)   def picturecreator(request):     if not request.user.is_authenticated():         return httpresponseredirect(reverse('world:loginrequest'))      if request.method == "post":         form = pictureform(request.user, request.post, request.files)         if form.is_valid():             picture = picture(user=request.user)              image = request.files.get('image')             if image:                 picture.image = form.cleaned_data['image']              description = form.cleaned_data['description']             if description:                 picture.description = form.cleaned_data['description']              if board:                 picture.board = form.cleaned_data['board']             picture.save()              board = whiteboard.objects.get(whiteboard=picture.board)             the_id = board.id         return httpresponseredirect(reverse('world:boat', kwargs={'animal_id': the_id }))        return render(request,'picture.html',{'form':pictureform(request.user)})
