Cambiar el mimetype feed de django, para que en chrome se vea bonito.

Me dice un cliente …

Andrés el rss feed de noticias de chrome no se ve bonito como en firefox. Y yo pues wtf si es el navegador que lo interpetra asi.

Es que mira como se ve aqui http://cofradia.org/feed/ lo quiero y yo WTF!!!

Ok ok revisemos

Segun la documentación del RSS El mimetype que devuelve django es “application/rss+xml” en chrome encuentra esto y muestra en plano el xml y no parsea bonito como si fuera un xml.

Para cambiar esto, hay que sobre escribir un metodo en la definicion del feed y dectar el user agent y cambiar el mimetype

from django.utils.translation import ugettext_lazy as _ from django.contrib.syndication.views import Feed from django.core.urlresolvers import reverse from models import Article from settings import NEWS_FEED_MAX_ARTICLES

class LatestNewsFeed(Feed): title = _("XXXXX") description = _("Updates on changes and additions to xxxxxx.")
