Django的reverse的作用

from django.conf.urls import url

from .views import iv_info

# urlpatterns = [

#     url('^iv_info/', iv_info)

# ]

urlpatterns = [

    url('^iv_info(\d+)/', iv_info, name='info')

]

from django.shortcuts import render

from django.urls import reverse

# from django.http import HttpResponse

# Create your views here.

def iv_info(request, num):

    new_url = reverse('info', args=(3, ))

    return render(request, 'iv_info.html', {'new_url':new_url})
