如何在ManytoMany字段中对Django管理员隐藏一些用户组

from django.contrib import admin
from django.contrib.auth.models import Group

class CustomModelAdmin(admin.ModelAdmin):
    def get_form(self, request, obj=None, **kwargs):
        form = super().get_form(request, obj, **kwargs)
        
        # 获取当前登录的管理员用户
        admin_user = request.user
        
        # 需要隐藏的用户组名称列表
        hidden_groups = ['Group1', 'Group2']
        
        # 根据需要隐藏的用户组进行过滤
        groups_to_exclude = Group.objects.filter(name__in=hidden_groups)
        
        # 使用exclude属性将需要隐藏的用户组从ManyToMany字段中排除
        form.base_fields['groups'].queryset = form.base_fields['groups'].queryset.exclude(id__in=groups_to_exclude)
        
        return form

# 注册你的ModelAdmin类
admin.site.register(YourModel, CustomModelAdmin)
