Django, custom tag... how?

I would like to make a django custom tag to display 10 entry titles from the category where the user is reading an article. How can I do this? I need to pass the category from the actual entry.

Solution

  • The best way to do this would be with an inclusion tag. This is a tag that renders a template fragment which renders the 10 related articles.

    You just pass in the current article into the tag, and return the context for the template fragment - ie the related articles.

    @register.inclusion_tag('related_articles.html')
def related_articles(article, count):
    category = article.category
    articles = category.article_set.exclude(id=article.id)[:count]
    return {'articles': articles}

    You'll need a related_articles.html file in your templates directory which outputs the articles. Then, to call it from your main template, you would just do 

    {% related_articles article 10 %}

    where article is the name of the article object.
