Hi Mohammad,
Check out slice
<https://docs.djangoproject.com/en/1.6/ref/templates/builtins/#slice>.
It's a builtin template filter that can be used like this:
{% for author in book.authors.all|slice:"3" %}
{# HTML up in here #}
{% endfor %}
Good luck,
Elliot

Hello django users. I am working on my first django project and I
faced a little problem.
I have a library database with books. A book element may have
several authors.
In the view function I query the database for books. I want to
show the *first three* authors. I was thinking to do something
similar to the following python code but using the template language:
authors_to_show = book.authors.get_queryset() [0:3]
for author in authors_to_show:
#html code here
However, it appears that I cannot define variables in the template
unless I extend the language a bit. Note that I have several books
to process and I can do that using the for loop in the template
language. But I want to ignore some authors in each book.
Any idea of a proper way to do this.
Thank you in advance,
Mohammad
