A simple
templatetag for adding to the template context a variable with the user timeline from
Twitter.
It uses the
CachedContextUpdatingNode snippet
for caching from
Jacob Kaplan-Moss.
The reason that is necessary to cache content is because
Twitter limits the number of accesses to the
API.
This only works if the
cache is enabled on your
settings.py.
class TwitterNode(CachedContextUpdatingNode):
cache_timeout = 1800 # 30 Minutes, maybe you want to change this
def __init__(self, username, varname):
self.username = username
self.varname = varname
def make_datetime(self, created_at):
return datetime.fromtimestamp(mktime(strptime(created_at, '%a %b %d %H:%M:%S +0000 %Y')))
def get_cache_key(self, context):
return 'twitter_user_timeline_cache'
def get_content(self, context):
try:
response = urllib.urlopen('http://twitter.com/statuses/user_timeline/%s.json' % self.username).read()
json = simplejson.loads(response)
except:
return {self.varname : None}
for i in range(len(json)):
json[i]['created_at'] = self.make_datetime(json[i]['created_at'])
return {self.varname : json}
@register.tag
def twitter_user_timeline(parser, token):
bits = token.contents.split()
if len(bits) != 4:
raise TemplateSyntaxError, "twitter_user_timeline tag takes exactly three arguments"
if bits[2] != 'as':
raise TemplateSyntaxError, "second argument to twitter_user_timeline tag must be 'as'"
return TwitterNode(bits[1], bits[3])
Usage:
{% twitter_user_timeline username as twitter_entries %}
{% if twitter_entries %}
{% for entry in twitter_entries %}
{{ entry.created_at|date:"d M Y H:i" }} - {{ entry.text }}
{% endfor %}
{% endif %}
