How To Generate URL And Route Dynamically In Flask

February 15, 2024

We can set route dynamically instead of fixed route.

For example In the pre-determined route links generate like this example.com/users/profile

In the dynamically gendered route will be like this  example.com/users/custom_profile_name

We will use

@app.route('/<username>')

The code will be like this

@app.route('/<username>')
def show_profile(username):
    return username

We can use anything in the <username> here

So if we  load page like example.com/anything_here

It will show the route. This is the complete example. Copy and try and customize the code by yourself.

from flask import Flask, url_for

app = Flask(__name__)

@app.route('/<username>')
def show_profile(username):
    return username

@app.route('/')
def index():
    example_link = url_for('show_profile', username='example')
    return f"You are on index route. Go to <a href='{example_link}'>/example</a> for an example."

if __name__ == '__main__':
    app.run(debug=True)

  
  Copy
