Django，自定义标签...怎么样？ [英] Django, custom tag... how?

问题描述

我想制作一个django自定义标签，从用户阅读文章的类别中显示10个条目标题。我该怎么做？我需要从实际条目中传递类别。

解决方案

最好的方式是使用包含标签。这是一个标签，用于呈现一个模板片段，呈现10个相关文章。

您只需将当前文章传递到标签中，并返回模板片段的上下文，即相关文章。

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

您需要在templates目录中输入一个related_articles.html文件才能输出文章。然后，从主模板中调用它，您只需执行

  {％related_articles article 10％} 
  

其中文章是文章对象的名称。 >

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.

解决方案

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.
