“article_set”在哪里？来自 Django？
我目前正在开发 Django/Pinax 应用程序（我确信我的问题不是 Pinax 特定的，这就是主题标题中没有提到 Pinax 的原因），我正在尝试弄清楚整个框架是如何工作的。现在，我必须编写一个视图来将数据传递到模板。我只在 django 手册中看到它的完成：在手册中，ObjectName.objects.all() 简单地传递给 render_to_response() 。我的任务有点复杂，所以我试图了解它是如何在 pinax 应用程序“配置文件”中完成的，但完全失败了。
因此，profile.html 模板文件有这样一行：
{% for article in other_user.article_set.all %}
“other_user”是传递给views.py 中的 render_to_response() 的“User”类的实例。好的，但是article_set不是它的类变量。我未能在应用程序代码中的任何位置找到article_set描述，但发现更多类似调用形式的内容出现：
{% for bookmark_instance in other_user.saved_bookmarks.all.select_related %}
搜索Django文档仅导致这个页面，没有告诉'article_set'到底是什么。
什么是article_set？它在哪里定义以及它如何工作？任何答案或只是文档链接都非常感谢。谢谢。
I am currently working on a Django/Pinax application (I'm sure my question is not Pinax-specific, that's why Pinax's not mentioned in the theme title), and I'm trying to figure out how the whole framework works. Right now, I have to write a view to pass data to a template. I've only seen it done in the django manual: In the manual, ObjectName.objects.all() is simply passed to render_to_response(). My task is somewhat more complicated, so I've tried to understand how it is done in a pinax application 'profiles', and failed completely.
So, profile.html template file has a line like this:
{% for article in other_user.article_set.all %}
'other_user' is an instance of the 'User' class passed to render_to_response() in views.py. Ok, but article_set is not its class variable. I've failed to find article_set description anywhere in the application code, but found more occurrences of something looking like the same form of call:
{% for bookmark_instance in other_user.saved_bookmarks.all.select_related %}
Searching Django docs only resulted in this page, not telling what 'article_set' exactly is.
What is article_set? Where is it defined and how does it work? Any answers or just documentation links are strongly appreciated. Thank you.
