How to fix django url?

Question

Django

The first request when using django-enless-pagination fails. But when you type the identity into the address bar with pens, everything works correctly. Why is that ? And how can anyone fix it?

[04/Jul/2015 14:33:31]"GET /?page=2&querystring_key=page HTTP/1.1" 500 160329
[04/Jul/2015 14:33:42]"GET /?page=2&querystring_key=page HTTP/1.1" 200 6458

from django.conf.urls import include, url
from django.contrib import admin
from endless_pagination.views import AjaxListView

urlpatterns = [
    url(r'^$', 'blog.views.index', name='home'),
    url(r'^add/', 'blog.views.add_post', name='add_post'),
    url(r'^admin/', include(admin.site.urls)),
    url(r'^accounts/', include('allauth.urls')),
]

from django.shortcuts import render
from django.http import HttpResponse , HttpResponseRedirect
from django.core.urlresolvers import reverse
from endless_pagination.decorators import page_template

from django.template import RequestContext

from endless_pagination.decorators import page_template
from .models import Posts
@page_template('blog/all_posts.html')  # just add this decorator
def index( request, template='blog/post.html', extra_context=None):
    post = Posts.objects.all()
    context = {'entries':post}
    if extra_context is not None:
        context.update(extra_context)

    return render_to_response(template, context, context_instance=RequestContext(request))

To see the error when returning 500 when sending by Ajax, just look in firebug`e or Google Chrome debugger. If DEBUG = True
The error may be that you are sending a POST request, but waiting for a GET from you. When you initialize the address in the browser, then there you do it with a GET request.
Third:
You are told that request.REQUEST is deprecated and advised to use `request.GET` or `request.POST`. Since it's in the library, try to update it (not always update in the stable public version, check the repository with the latest version).

The problem was in the templates twice, extends was replaced by include in one MANY THANK YOU
