如何从 Django 视图中分配用户组？

Question

我有用户的 CRUD 操作，只能从管理员角色完成。我有 6 个不同的角色，我通过创建组并将用户分配到管理面板中的特定组来创建这些角色。

我的问题是，当管理员创建新用户时，是否有一些方法可以将这些组字段包含在下拉菜单中，这样他就可以选择要分配给新用户的组，而不是从管理面板中选择？

任何帮助将不胜感激:)

model.py

class CustomUserManager(BaseUserManager):

    def create_user(self, email, password, **extra_fields):

        if not email:
            raise ValueError(_('The Email must be set'))
        email = self.normalize_email(email)
        user = self.model(email=email, **extra_fields)
        user.set_password(password)
        user.save()
        return user

    def create_superuser(self, email, password, **extra_fields):

        extra_fields.setdefault('is_staff', True)
        extra_fields.setdefault('is_superuser', True)
        extra_fields.setdefault('is_active', True)

        if extra_fields.get('is_staff') is not True:
            raise ValueError(_('Superuser must have is_staff=True.'))
        if extra_fields.get('is_superuser') is not True:
            raise ValueError(_('Superuser must have is_superuser=True.'))
        return self.create_user(email, password, **extra_fields)


class CustomUser(AbstractUser):

    username = None
    email = models.EmailField(_('email address'), unique=True)

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = []

    objects = CustomUserManager()

    def __str__(self):
        return self.email

    username                        = models.CharField(max_length=30, blank=True, default='')
    is_superuser                    = models.BooleanField(default=True)
    is_admin                        = models.BooleanField(default=True)
    is_employee                     = models.BooleanField(default=True)
    is_headofdepartment             = models.BooleanField(default=True)
    is_reception                    = models.BooleanField(default=True)
    is_patient                      = models.BooleanField(default=True)
    is_active                       = models.BooleanField(default=True)
    is_staff                        = models.BooleanField(default=True)

forms.py

class UserForm(ModelForm):
    class Meta:
        model = CustomUser
        fields = ['email', 'password',]

useradd.html

<h1 class="display-4">Add new user</h1>
            <form action="" method="post" autocomplete="off">
                {% csrf_token %}
                {{ form.as_p }}
                    <button type="submit" class="btn btn-success">Save </button>

views.py

@login_required
@admin_only
def users(request):
    context = {'users': CustomUser.objects.all()}
    return render(request, 'users.html', context)

@login_required
def users_add(request):
    if request.method == "POST":
        form = UserForm(request.POST)
        if form.is_valid():
            users = CustomUser.objects.create_user(**form.cleaned_data)
            #login(request, users)
            # redirect, or however you want to get to the main view
            return redirect('feedback:users')
    else:
        form = UserForm() 

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

您可以使用 ModelChoiceField 在表单中包含 select 小部件。所以请试试这个代码：

forms.py

from django.contrib.auth.models import Group
from django.forms import ModelForm, ModelChoiceField

from app.model import CustomUser


class UserForm(ModelForm):

    class Meta:
        model = CustomUser
        fields = [
            'email',
            'password',
        ]

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.fields['group'] = ModelChoiceField(
            queryset=Group.objects.all(),
            empty_label='No group'
        )

在model.py

中更改CustomUserManager.create_user方法

from django.contrib.auth.models import Group


class CustomUserManager(BaseUserManager):

    def create_user(self, email: str, password: str, group: Group, **extra_fields):
        if not email:
            raise ValueError(_('The Email must be set'))

        email = self.normalize_email(email)
        user = self.model(email=email, **extra_fields)
        user.set_password(password)
        user.save()

        if group is not None:
            group.user_set.add(user)

        return user
