符号|鉴于Flask教程 [英] Symbol | in view for Flask tutorial

问题描述

我正在为Flask框架做一个教程，在，但是对于这个特定的例子，这不是它们如何使用。

I'm doing a tutorial for the Flask framework at http://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-iii-web-forms In this very chapter I've found a piece of code that I didn't understand. It is:

|{% for pr in providers %}
<a href="javascript:set_openid('{{pr.url}}', '{{pr.name}}');">{{pr.name}}</a> |
{% endfor %}

Why do we need the symbol | there?

解决方案

This pipe is simply adding the | between providers, as seen in the screenshot. Notice the symbol between "Google" and "Yahoo"

Pipes are used in filters, but for this specific example, that is not how they are used.
