base.html 中的 Django 变量
[英]Django variable in base.html
问题描述
base.html is used as the base template for all other pages. 
base.html用作所有其他页面的基本模板。 base.html has the navigation bar and in the navigation bar, I want to show the number of messages the user received. base.html有导航栏，在导航栏中，我想显示用户收到的消息数。 Thus, I need to have a variable like {{number_of_messages}} in the base.html .因此，我需要在base.html有一个像{{number_of_messages}}这样的变量。
However, how should I pass this variable to it?但是，我应该如何将这个变量传递给它？ Every template extends base.html and is rendered by a function.每个模板都扩展了base.html并由一个函数呈现。 I don't think returning number_of_messages in all functions is a good way.我不认为在所有函数中返回number_of_messages是一个好方法。 Is there better way to implement this?有没有更好的方法来实现这一点？ How can I pass this variable to all templates?如何将此变量传递给所有模板？
