Include a URL in a Django template tag

I'm building a Django blog app, since that's apparently what all the cool kids are doing. I've built a template tag to display only the beginning of the post if it's long, and ideally to include a link to the whole post. I started looking into escaping and IsSafe=True, but my worry is that the content itself could have HTML tags in it that could mess things up.

Here's what I have now:

@register.filter(name='shorten')
def shorten(content):
    #will show up to the first 500 characters of the post content
    if len(content) > 500:
        return content[:500] + '...' + <a href="/entry/{{post.id}}">(cont.)</a>
    else:
        return content

from django.utils.safestring import mark_safe

@register.filter(name='shorten')
def shorten(content, post_id):
    #will show up to the first 500 characters of the post content
    if len(content) > 500:
        output = "{0}... <a href='/entry/{1}'>(cont.)</a>".format(content[:500], post_id)
    else:
        output = "{0}".format(content)

    return mark_safe(output)
