Django planmember_set问题

Question

我有一个问题，我希望有人可以帮助我。我正在使用表单让用户选择一个“计划”。现在我想在表单中列出计划中的所有成员。我有一个函数“get_owners”，抓住计划中的所有成员，通过使用该功能：

def get_owners(self): 
    owners = self.planmember_set.filter(ownership_type__code__in=["primary","joint"]) 
    return owners 

唯一的问题是，我得到的输出：

[<PlanMember: Doe, John (Primary)>, <PlanMember: Doe, Jane(Joint Subscriber)>, etc] 

现在有没有办法让我只显示他们的名字和成员类型（括号内的单词）？

有点背景代码。

这里是我的views.py：

if request.POST: 
    form = PlanMaturityYearForm(Plan.objects.all().filter(profile = p), request.POST) 
    if form.is_valid(): 
     selected_plan = form.cleaned_data['plans'] 
     plan = get_object_or_404(Plan, pk=selected_plan.pk) 
     investment_list = Investment.objects.all().filter(Q(plan = plan)).order_by('maturity_date') 
     context['investment_list'] = investment_list 
     context['plan'] = plan 
     context['today'] = now 
     context['current_yr'] = current_year 
     context['next_yr'] = next_year 
     context['show_report'] = True 
else: 
    form = PlanMaturityYearForm(Plan.objects.all().filter(profile = p)) 
context['form'] = form 
return render_to_response('reports/planmaturities_year.html', RequestContext(request, context)) 

而且我forms.py：

class PlanMaturityYearForm(forms.Form): 
def __init__(self, plans, *args, **kwargs): 

    super(PlanMaturityYearForm, self).__init__(*args, **kwargs) 
    self.fields['plans'] = forms.ModelChoiceField(
     plans, 
     required=True, 
     widget=forms.Select(attrs={'size': 20}), 
     error_messages={'required':'Please select the plan you wish to build the report for',} 
    ) 

编辑：

Answer 1

你能够 使用values_list：

owners = self.planmember_set.filter(
      ownership_type__code__in=["primary","joint"] 
     ).values_list('name', 'type') 

Answer 2

def get_owners(self): 
    owners = self.planmember_set.filter(ownership_type__code__in=["primary","joint"]).values_list('name_field', 'ownership_type__code') 
    return owners 

写到哪，你如何如不正确使用get_owners。
