Получение ошибки при попытке удалить команду Django

Когда я пытаюсь добавить delete к моим представлениям, я получаю ошибку:

Запрос, соответствующий команде, не существует.

Что я делаю не так? Похоже, что трассировка приводит меня к context_processor.py. Вот мой код ниже:

Views.py

@login_required
def team(request, team_id):
    team = get_object_or_404(Team, pk=team_id, status=Team.ACTIVE, members__in=[request.user])
    invitations = team.invitations.filter(status=Invitation.INVITED) 

    return render(request, 'team/team.html', {'team': team, 'invitations': invitations})

@login_required
def activate_team(request, team_id):
    team = get_object_or_404(Team, pk=team_id, status=Team.ACTIVE, members__in=[request.user])
    userprofile = request.user.profile
    userprofile.active_team_id = team.id
    userprofile.save()

    messages.info(request, 'The team was activated')

    return redirect('team:team', team_id=team.id)

@login_required
def add(request):
    profile = request.user.profile
    form = TeamForm()
    if request.method == 'POST':
        form = TeamForm(request.POST, request.FILES)

        if form.is_valid():
            team = form.save(commit=False)
            team.created_by = request.user
            team.save()
            team.members.add(request.user)


            profile.active_team_id = team.id
            profile.save()

            return redirect('account')

    context = {'form': form}
    return render(request, 'team/add.html', context)

    #profile = request.user.profile
    team = get_object_or_404(Team, pk=request.user.profile.active_team_id, status=Team.ACTIVE, members__in=[request.user])
    form = TeamForm(instance=team)
    if request.method == 'POST':
        form = TeamForm(request.POST, request.FILES, instance=team)

            team.save()           

            messages.info(request, 'The changes was saved')

        return redirect('account')

Я считаю, что запрос на удаление

team = Team.objects.get(pk=request.user.profile.active_team_id)

не возвращает никакого результата, поэтому вы не можете выполнить удаление с объектом team

попробуйте следующее:

@login_required
def delete(request, pk):    
  try:
      team = Team.objects.get(pk=request.user.profile.active_team_id)
      if request.method == 'POST':
          team.delete()
          return redirect('account')
      context = {'object': team}
      return render(request, 'team/delete.html', context)
  except Team.DoesNotExist:
      raise Http404("No Team found for the user")

или лучше использовать get_object_or_404, как в функции edit:

@login_required
def delete(request, pk):    
  team = get_object_or_404(Team, pk=request.user.profile.active_team_id)
  if request.method == 'POST':
      team.delete()
      return redirect('account')
  context = {'object': team}
  return render(request, 'team/delete.html', context)

Контекстные процессоры выполняются всякий раз, когда происходит рендеринг шаблона.

Вы не можете .get() удалить команду после ее удаления.

  1. Вместо этого используйте .filter() и .first(): 
def active_team(request):
    if request.user.is_authenticated:
        if request.user.profile.active_team_id:
            # team = Team.objects.get(pk=request.user.profile.active_team_id)           # Change this
            team = Team.objects.filter(pk=request.user.profile.active_team_id).first()  # to this

            return {'active_team': team}
            
    return {'active_team': None}
  1. Вероятно, вы хотите снять флажок активной команды пользователя при удалении команды:
@login_required
def delete(request, pk):    
    team = Team.objects.get(pk=request.user.profile.active_team_id)
    if request.method == 'POST':
        team.delete()

        # Unset user's active team
        request.user.profile.active_team_id = None
        request.user.save()

        return redirect('account')
    context = {'object': team}
    return render(request, 'team/delete.html', context)
