Question

forms.py

status_list = (
    ('', ''),
    ('c', 'cancelado'),
    ('elab', 'em elaboração'),
    ('p', 'pendente'),
    ('co', 'concluido'),
    ('a', 'aprovado')
)

class StatusSearchForm(forms.Form):
    status = forms.ChoiceField(
        choices=status_list, widget=forms.Select(attrs={'class': 'form-control'}))

模板

Status {% for radio in status_search_form.status %} {{ radio }} {% endfor %}

views.py

class ProposalList(ListView):
    template_name = 'core/proposal/proposal_list.html'
    model = Proposal
    paginate_by = 10

    def get_context_data(self, **kwargs):
        context = super(ProposalList, self).get_context_data(**kwargs)
        context.update({'status_search_form': StatusSearchForm(), })
        return context

    def get_queryset(self):
        p = Proposal.objects.all().select_related()
        q = self.request.GET.get('search_box')
        if q is not None:
            try:
                p = p.filter(
                    Q(id__icontains=q) |
                    Q(work__name_work__icontains=q) |
                    Q(work__customer__first_name__icontains=q) |
                    Q(category__category__startswith=q) |
                    Q(employee__user__first_name__startswith=q) |
                    Q(seller__employee__user__first_name__startswith=q) |
                    Q(created__year=q))
            except ValueError:
                pass
        s = self.request.GET.get('status')
        if s is not None:
            p = p.filter(status__exact=s)
        elif s == '':
            p = p
        return p

问题：当我选择“状态”的第一个选项时，我想要，在这种情况下是空的，他正常返回所有记录，问题是它正在返回

http://localhost:8000/proposal/?status=&search_box=

它不返回任何东西。但在这种情况下，我想要全部归还。

什么是最好的解决方案？

def get_context_data(self, **kwargs):
        status_classes = {'c': 'fa-close status-cancelado',
                          'elab': 'fa-circle status-elab',
                          'p': 'fa-circle status-pendente',

                          'a': 'fa-star status-aprovado'}
        context = super(ProposalMixin, self).get_context_data(**kwargs)
        context.update({'status_search_form': StatusSearchForm(), })
        context['status'] = [(item, item_display, status_classes[item])
                             for item, item_display in STATUS_FILTER]

return p

使用ChoiceField（Django）过滤
