python - Django variable from Model not outputting value in template -

the variable {{ post }} gives value in home page, , allows me redirect post page proper id; however, page redirected not display value {{ post }}. i'm not sure issue is, tried change multitude of things, can't seem find problem. how can variable {{ post }} give output on other pages?

here index.html, , articles page:

{% if news_posts %} <div class="row">     <div class="large-8 small-12 large-centered column" id="articles">         <ul class="article_posts">             {% post in news_posts %}                 <li id="article_title"><a href="{% url 'articles:post' post.id %}">{{ post.post_title }}</a></li>                 <li id="article_date">posted {{ post.post_date|timesince }} ago</li>                 <div id="arrow"></div>                 <hr>                 <li id="article_image"><img src="static/media/{{ post.post_image }}" /></li>                 <li id="article_shortdesc">{{ post.post_short_description }}</br><a href="{% url 'articles:post' post.id %}">read more>>></a></li>                 <hr>             {% endfor %}         </ul>        </div> </div> {% endif %} 

the articles template page:

<div class="row">     <div class="large-8 small-12 large-centered column" id="articles">         <ul class="article_posts">                 <li id="article_title">{{ post.post_title }}</li>                 <li id="article_date">{{ post.post_date }}</li>                 <hr>                 <li id="article_image"><img src="static/media/{{ post.post_image }}" /></li>                 <li id="article_shortdesc">{{ post.post }}</li>                 <hr>         </ul>        </div> </div> 

views.py

from django.shortcuts import render, render_to_response articles.models import newspost django.views import generic articles.forms import requesteditor django.core.context_processors import csrf  class postlist(generic.listview):     template_name = 'articles/index.html'     context_object_name = "news_posts"     paginate_by = 5      def get_queryset(self):         return newspost.objects.order_by('-post_date')[:5]  class postdetail(generic.detailview):     model = newspost     template_name = 'articles/articles.html' 

the apps urls.py

from django.conf.urls import patterns, include, url  articles import views  urlpatterns = patterns('',      url(r'^$', views.postlist.as_view(), name='index'),     url(r'^(?p<pk>\d+)/$', views.postdetail.as_view(), name='post'),     url(r'^editors_request_form/$', views.editorsrequestform, name='editors'), ) 

project urls.py

from django.conf.urls import patterns, include, url django.contrib import admin  urlpatterns = patterns('',     # examples:     # url(r'^blog/', include('blog.urls')),      url(r'^', include('articles.urls', namespace="articles")),     url(r'^editor_login/', include(admin.site.urls)), ) 

you need add context_object_name='post' in postdetailview otherwise, default template variable name used object.
