Question

I fetched tweets from twitter. In the template tweets loop, I tried to print how long ago this tweet was created. So this is what I tried:

<li class="twitter-feed-block-content">
  {{ tweet.text }}
  <span class="when">
    {{ tweet.created_at|timesince }}
  </span>
</li>

{{tweet.text}} is printing correctly. However, when I add the next line {{ tweet.created_at|timesince }} I get the following error:

Exception Value:     'unicode' object has no attribute 'year' Exception
Location:   REMOVED_BY_ME/lib/python2.7/site-packages/django/utils/timesince.py
in timesince, line 29 Python
Executable: REMOVED_BY_ME/bin/python
Python Version: 2.7.2

The tweet.created_at is a string. Is this the reason? if so, how I can convert it so that it works seamless with timesince filter?

Thanks in advance

Ok, this is how I’ve solved the question. As I told, I wanted to create custom filter as a last resort only.

So, i’ve created a filter named strtotimesince. i’m putting it here so that it helps if someone faces similar problem.

from django.utils import timesince

@register.filter(name='strtotimesince')
def strtotimesince(value,format=None):
    if not value:
        return u''

    if not format:
        format = "%a %b %d %H:%M:%S +0000 %Y"
    try:
        convert_to_datetime = datetime.strptime(value, format)
        if convert_to_datetime:
            return "%s ago" % timesince.timesince(convert_to_datetime)
    except:
        return ''
