Flask is one of my Python frame work in which I build simple web application with ease and peace. Today we learn how to pass a variables to other templates in a Flask application.
Suppose your web app have a base template and a top nav bar template which included using
{% include "site_template/top_navigation.html" %}
and you want to pass a title or something else from a Index page to navigation bar where you want show up some text.
Using {% set %} you can create global variables.
The solution
We can use a set block in top of the index page as follows ,to pass variables to other sub templates
{% set mytitle=title %}
In the route it will look like
return render_template('index.html', title=title)
and in the nav bar page we can use as mytitle as variable using
<div id="site_title"><h2 >{{ mytitle}} </h2></div>
If you had doubt and suggestion please leave a comment
