django筛选特定用户组中的客户

问题描述

我想在ListView中显示特定组中的客户，而无法理解如何获取查询集

class CustomerList(ListView):
  model = Customer
  queryset = Customer.objects.filter(member__groups__name__in=['online','whatsapp'])
  template_name = 'customer/customer_list.html'

models.py

class Customer(models.Model): 
    member = models.ForeignKey(User,verbose_name=_("Customer"),on_delete=models.CASCADE)
    contact = models.ForeignKey(Contact,verbose_name=_("Contact"),on_delete=models.CASCADE,blank=True,null=True)
    ...

将客户添加到以下组：

class AddUser(CreateView):
  def post(self,request,*args,**kwargs):
     form = UserForm(request.POST) 
     if form.is_valid(): 
        user = form.save(commit=False)
        group,created = Group.objects.get_or_create(name='online')
        user.groups.add(group)
        user.save()

解决方法

我有类似的代码在工作，请检查它是否对您有用-

class ProfessorsList(generic.list.ListView):
  model = Staff
  queryset = Staff.objects.filter(member__groups__name='teaching')

对于多个小组，您可以这样做：（我相信您已经在这么做了……）

Customer.objects.filter(member__groups__name__in=['online',...])

如果仍然无法使用，请尝试以下操作：

  users = User.objects.filter(groups__name__in=[your_groups])
  queryset = Customer.objects.filter(member__in=users)

确保customers具有users，并且users是your_groups的一部分
