 class Meta:
        model = Job

models.py

There is no built-in filter to limit a string to a certain number of characters, but you can limit to a certain number of words:

{{ job.description|truncatewords:20 }}

http://docs.djangoproject.com/en/dev/ref/templates/builtins/?from=olddocs#truncatewords

If you really want to restrict to a number of characters, you will have to write your own custom filter.
