由于未在 Django 视图中显示，如何显示用户组？

Question

我研究了几天，但在 django 的文档中没有太多关于组的信息，而且真的不知道要更改什么以便显示组。

我有用户的 CRUD 操作，只能由管理员完成，他可以将用户分配到 6 个不同的组。它保存在数据库中，一切正常。我现在面临的问题是这些组在我的视图中没有可视化（在 UI）。

我附上图片来说明我的意思： groups

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):
    password = forms.CharField(widget=forms.PasswordInput)
    group = forms.ModelChoiceField(queryset=Group.objects.all())

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

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.fields['group'] = ModelChoiceField(
            queryset=Group.objects.all(),
            empty_label='Избери'
        )

            #login(request, users)
            # redirect, or however you want to get to the main view

    else:

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

Answer 1

如果有人需要这个解决方案，因为 Group 是与 User 的多对多关系，它需要遍历与每个用户关联的所有 Group 对象。

<td>
{% for group in user.groups.all %}
{{ group.name }}
{% endfor %}
<td>
