I'm trying to create a custom template tag. I've added a feedimport
app in my project, added it on my installed apps, and inside it I've
created a templatetag directory with a file feed_import.py
Both feedimport and templatetag dirs have an empty __init__.py file.
I'm trying to load my feedimport with
{% load feedimport %} in a template, but it says:
TemplateSyntaxError: 'feed_import' is not a valid tag library: Could
not load template library from django.templatetags.feed_import, No
module named feedparser
What's wrong?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This is the source code of my feed_import.py file:
import urllib, os, time, datetime, feedparser
from django.conf import settings
from django import template
register = template.Library()
@register.inclusion_tag('feedimport/pull_feed.html')
def pull_feed(feed_url, posts_to_show=5, cache_expires=30):
CACHE_FILE = ''.join([settings.CACHE_FOLDER,
template.defaultfilters.slugify(feed_url), '.cache'])
try:
cache_age = os.stat(CACHE_FILE)[8]
except: #if file doesn't exist, make sure it gets created
cache_age = 0
#is cache expired? default 30 minutes (30*60)
if (cache_age + cache_expires*60 < time.time()):
try: #refresh cache
urllib.urlretrieve(feed_url,CACHE_FILE)
except IOError: #if downloading fails, proceed using cached file
pass
#load feed from cache
feed = feedparser.parse(open(CACHE_FILE))
posts = []
for i in range(posts_to_show):
pub_date = feed['entries'][i].updated_parsed
published = datetime.date(pub_date[0], pub_date[1], pub_date[2] )
posts.append({
'title': feed['entries'][i].title,
'summary': feed['entries'][i].summary,
'link': feed['entries'][i].link,
'date': published,
})
return {'posts': posts}
