如何在Flask模板中显示当前年份？ [英] How to display current year in Flask template?

问题描述

我正在寻找如何在Flask模板中输出当前年份。我知道在Django中您可以使用 {％now Y％}。，但是有Flask等效项吗？到目前为止，我一直无法找到任何东西。

I am looking to find out how to output the current year in a Flask template. I know in Django you can use {% now "Y" %}., but is there a Flask equivalent? I have been unable to find anything during my research thus far.

推荐答案

使用模板上下文处理器，将当前日期传递给每个模板，然后呈现其 year 属性。

Use a template context processor to pass the current date to every template, then render its year attribute.

from datetime import datetime

@app.context_processor
def inject_now():
    return {'now': datetime.utcnow()}

{{ now.year }}

或者如果大多数模板中不需要它，请使用 render 传递对象。

Or pass the object with render if you don't need it in most templates.

return render_template('show.html', now=datetime.utcnow())
