python - 无法将关键字“approve_moderator”解析为字段。选项有：id、user、user

问题描述

问题概要：

我正在实现一个登录逻辑，该逻辑检查用户是否已注册并在 MODERATOR 组中（用户在注册时自动添加到 MODERATOR 组），“approve_moderator”状态设置为 True。默认情况下，“approve_moderator”字段为 False。现在在登录期间，我检查用户是否是注册用户并在将他们重定向到主持人仪表板之前获得批准

视图.py


def is_moderator(user):
    '''check if registered and in moderator group'''
    return user.groups.filter(name='MODERATOR').exists()

def afterlogin_view(request):
    if is_student(request.user):
        messages.success(request, 'successfully logged in as ' + request.user.username)
        return redirect('student-dashboard')

    elif is_moderator(request.user):
        approval_status = Moderator.objects.all().filter(user_id=request.user.id, approve_moderator=True)
        if approval_status:
            return redirect('moderator-dashboard')
        else:
            return redirect('moderator-wait-approval')
    elif is_admin(request.user):
        return redirect('admin-dashboard')
    else:
        return redirect('login')

def register_moderator_view(request):
    if request.user.is_authenticated and request.user.is_moderator:
        return redirect('moderator-dashboard')
    else:
        form = RegistrationForm()
        if request.method == 'POST':
            form = RegistrationForm(request.POST, request.FILES)
            if form.is_valid():
                user = form.save(commit=False)
                user.is_moderator = False
                user.save()
                moderator = Moderator.objects.create(user=user)
                moderator_group, created = Group.objects.get_or_create(name='MODERATOR')
                moderator.user.groups.add(moderator_group)
                messages.info(request, 'Registration successful!')
                return redirect('login')
            # else:
            #     messages.warning(request, 'Form invalid!')
        form = RegistrationForm()
    return render(request, 'accounts/register.html', {'form': form })
