我的网址分批

from django.conf.urls import urlfrom . import vIEwsurlpatterns = [    # /batches/    url(r'^$',vIEws.index,name='index'),# /batches/2    url(r'^(?P<batches_ID>[0-9]+)/$',vIEws.detail,name="detail"),# businessname/1    url(r'^(?P<businessname_ID>[0-9]+)/$',vIEws.index_businessname,name="detail_businessname"),# indivIDuals/1    url(r'^(?P<indivIDuals_ID>[0-9]+)/$',vIEws.index_indivIDuals,name="detail_indivIDuals"),]

解决方法 索引视图有两个参数.您编写的URL仅提供请求.您必须将pk作为输入提供,就像详细URL一样 总结
