Question

class Article(models.Model):
    def user_may_see_full_version(self, user):
        # do something very sophisticated with the user
        return [True/False whatever]

now i want to create a template like this:

{% for article in articles %}
    {% if article.user_may_see_full_version request.user %}{{ article }}{% else %}{{article.title }}{% endif %}
{% endfor %}

but this doesn’t work because I can’t pass the argument to the method…

Is there any nice way to solve this problem?

Answer 1

There’s no way to pass an argument to a method directly from a template. A template filter is the best way to go:

{% if article|user_may_see_full_version:user %}{{ article }}{% else %}{{article.title }}{% endif %}

The filter is implemented like this:

@register.filter()
def user_may_see_full_version(article, user):
    return article.user_may_see_full_version(user)
