Continuation of the story.
I've looked into few feed generating libraries but they either seems
outdated or too large and complex for my needs.
So for now I just decided to generate very simple RSS XML manually:
@expose()
def rssfeed(self):
feed = u'<?xml version="1.0" encoding="utf-8"?>' \
'<rss version="2.0">'\
'<channel>' \
'<title>Кафе Альфа — новости</title>' \
'<link>http://127.0.0.1:8000</link>' \
'<description>Новости команды Кафе
Альфа</description><language>ru</language>'
feed +=
'<lastBuildDate>{0}</lastBuildDate>'.format(datetime.today())
for news in
DBSession.query(News).order_by(News.id.desc()).limit(5).all(): # last 5
news
item = u'<item>' \
u'<title>{title}</title>' \
u'<link>{link}</link>' \
u'<description>{description}</description>' \
u'<dc:creator
xmlns:dc="http://purl.org/dc/elements/1.1/";>{author}</dc:creator>' \
u'<pubDate>{date}</pubDate>' \
u'</item>'.format(title=news.title, link=news.url,
description=news.text,
author=news.author.display_name,
date=news.date)
feed += item
feed += u'</channel></rss>'
return feed
