Django: 'NoneType' Objekt hat kein Attribut 'Benutzer'

Question

Ich benutze Django Benutzermodell für eines der Auswahlfelder. Ich bin jedoch nicht in der Lage, nur Benutzer zu übergeben, die mit einer allgemeinen Organisation/Firma verbunden sind.

Ich habe eine onetoone Profilverknüpfung für jeden Benutzer. Dieses One-to-Oneo-Modell ist wiederum mit dem Organisationsmodell verknüpft.

Jetzt brauchen Sie ein Formular, in dem das Feld Benutzer mit dem Organisationsmodell verknüpft sein sollte.

Hier ist meine form.py:

class taskaddform(forms.ModelForm): 
    def __init__(self,user, *args, **kwargs): 
     self.user = kwargs.pop('user', None) 
     self.request = kwargs.pop('request', None) 
     super(taskaddform, self).__init__(*args, **kwargs) 
     self.fields["assigned_to"].queryset=User.objects.filter(company=self.request.user.company.entity) 
    class Meta: 
     model=tasktable 
     fields=('task','assigned_to','discription','documents',) 

views.py:

@login_required 
def taskadd(request): 
    if request.method=='POST': 
     form=taskaddform(request.POST,request.FILES,request.user) 
     if form.is_valid(): 
      new_form=form.save(commit=False) 
      new_form.created_by=request.user 
      new_form.company=request.user.company.entity 
      new_form.save() 
      return HttpResponseRedirect(reverse('taskadd'),messages.add_message(request, messages.SUCCESS,'Task added succesfully.')) 
    else: 
      form=taskaddform(request.user) 

    return render(request,'taskadd.html',{'form':form})

Aktualisierte ansichten.py.

@login_required 
def taskadd(request): 
    if request.method=='POST': 
     form=taskaddform(request, request.POST,request.FILES,request.user) 
     if form.is_valid(): 
      new_form=form.save(commit=False) 
      new_form.created_by=request.user 
      new_form.company=request.user.company.entity 
      new_form.save() 
      return HttpResponseRedirect(reverse('taskadd'),messages.add_message(request, messages.SUCCESS,'Task added succesfully.')) 
    else: 
      form=taskaddform(request) 

    return render(request,'taskadd.html',{'form':form}) 

und in Ihrem forms.py -

class taskaddform(forms.ModelForm): 
    def __init__(self, request, *args, **kwargs): 
     self.request = request 
     super(taskaddform, self).__init__(request, *args, **kwargs) 
     self.fields["assigned_to"].queryset=User.objects.filter(company=self.request.user.company.entity)
