Question

我正在尝试使用一个显示客户下拉列表的表单。当用户选择客户时，我想使用所选择的客户名称在同一个html页面中执行某些操作。我使用POST方法，我收到Method Not Allowed (POST): /opsform/错误。如果我使用GET，则URL具有我选择的值，但不会触发views.py中的getCustName方法。我搜索得足够多，并尝试了所有建议，但无法完成这项工作。以下是相关文件。请帮忙。

view.py

from django.shortcuts import render, get_object_or_404
from django.views import generic
from opsform.models import Customer, Tracking
from django.http.response import HttpResponse, HttpResponseRedirect
from django.core.urlresolvers import reverse


# Create your views here.
class DetailCustomer(generic.ListView):
    template_name = 'customerdrop.html'
    context_object_name = 'customerdrop'

    def get_queryset(self):
        """Return the all the customer information."""
        return Customer.objects.all()

def getCustName(request,cust_name):
    customer = get_object_or_404(Customer, pk=cust_name)

        selected_track =  customer.tracking_set.get(pk=request.GET['cust_name'])

        selected_track.votes += 1
        selected_track.save()

        return HttpResponseRedirect(reverse('opsform:vote', args=(customer.customer_id,)))

Urls.py

  from django.conf.urls import url

from . import views

app_name='opsform'
urlpatterns = [

    url(r'^$', views.DetailCustomer.as_view(), name='customerdrop'),


]
