尝试更改 new_manager.user.is_employee = False 并将其设置为 new_manager.user.is_manager = True ，但不起作用

Question

将用户转换为管理员后，我需要设置 'is_employee = False' 和 'is_manager = True'。这个过程看起来很简单，但我无法让它工作。

models.py

class User(AbstractUser):
is_admin = models.BooleanField(default=False)
is_employee = models.BooleanField(default=True)
is_manager = models.BooleanField(default=False)

def __str__(self):
    return f'{self.first_name} {self.last_name} as {self.username}'


class Manager(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
user_profile = models.OneToOneField(Profile, on_delete=models.CASCADE)
business_unit = models.OneToOneField(BusinessUnit, on_delete=models.SET_NULL, null=True)
previous_business_units = models.CharField(max_length=100, default=None, blank=True, null=True)
manager_description = models.TextField(blank=True, null=True)
manager_created_date = models.DateTimeField(auto_now_add=True, blank=True, null=True)

def __str__(self):
    return f'{self.user.first_name} {self.user.last_name}'

views.py

@login_required
@admin_required
def manager_create_view(request):
form = ManagerCreationForm()
if request.method == 'POST':
    form = ManagerCreationForm(request.POST)
    if form.is_valid():
        new_manager = form.save(commit=False)
        group = Group.objects.get(name='Manager')
        new_manager.user.groups.add(group)
        new_manager.user.is_employee = False
        new_manager.user.is_manager = True
        new_manager = form.save()
        new_manager = form.cleaned_data.get('user')
        messages.success(request, f'{new_manager} is now a Manager!')
        return redirect ('list-managers')
    messages.error(request, 'Something went wrong, please check the hilighted field(s)')
context = {
    'title': 'Create Manager',
    'form': form
}
return render(request, 'managers/manager-form.html', context)

我也尝试过使用信号，但没有成功。

signals.py

from django.db.models.signals import post_save
from accounts.models import User, Manager
from django.dispatch import receiver

@receiver(post_save, sender=Manager)
def change_user_type(sender, instance, created, **kwargs):
  if created:
    instance.user.is_manager = True
    instance.user.is_employee = False

尝试自学，如有任何帮助，将不胜感激！ :)

您需要保存管理员的用户，而不仅仅是管理员本身，所以：

@login_required
@admin_required
def manager_create_view(request):
    form = ManagerCreationForm()
    if request.method == 'POST':
        form = ManagerCreationForm(request.POST)
        if form.is_valid():
            new_manager = form.save()  # 🖘 save the manager object
            group = Group.objects.get(name='Manager')
            <strong>user = new_manager.user</strong>
            user.groups.add(group)
            user.is_employee = False
            user.is_manager = True
            <strong>user.save()</strong>  # 🖘 save the user object
            messages.success(request, f'{user} is now a Manager!')
            return redirect('list-managers')
        messages.error(request, 'Something went wrong, please check the hilighted field(s)')
    context = {
        'title': 'Create Manager',
        'form': form
    }
    return render(request, 'managers/manager-form.html', context)
