Jinja filters

What is wrong?

Report a typo

The following is an attempt to create a custom filter to identify the mistake.

from flask import Flask, render_template
app = Flask(__name__)

@app.route("/")
def home():
    return render_template("home.html")

@app.template_filter('half_of') 
def half(num):
  return int(num)/2

if __name__ == '__main__':

    app.run()

Where home.html is a template that contains {{ 3 | half }}.

Can you tell what's wrong?

Select one or more options from the list

Nothing wrong with the code

{{ 3 | half }} should be {{ half(3) }}

the name of the filter inside the template should be half_of

Filter defined after the template is rendered
