No, because that filter call will require an argument, and you can't
call methods with arguments in the template language. As you say,
create a model method (or better, a method on the Manager).

filtering related object in template

[Martin Tiršel]

Hello,

I can do:

{% for image in gallery.image_set.all %}
...
{% endfor %}

but my image model has:
is_thumbnail = models.BooleanField()

and I want to limit displaying only these images which have  
is_thumbnail=True. I can create a method on the image model, which returns  
images I want to, but is it possible in template too?


Thanks,
Martin
