Mapping the URLs to a specific function is called App Routing. This is the logic for that URL. Users will easily remember the URLs by making them meaningful and making navigation simpler. For example, The URL ("/") is linked with the root URL. The __name__ is a special built-in variable. It evaluates the name of the current module. 


In Flask, the route() decorator is used to bind a URL to a function. As a result, when the URL is typed in the browser, the function is executed, or the corresponding output will get displayed. Here, the URL '/user/username' rule is bound to the username function. As an outcome, if a user visits http://localhost:5000/ URL, the output of the username will be rendered in the browser. 

Benefits of the Dynamic URL Building 

  • It avoids hard coding of the URLs. 
  • Instead of remembering the manually changed URLs, we can change the URLs dynamically. 
  • URL building handles Unicode data transparently and the escape of special characters. 
  • The generated paths are always absolute. It avoids unexpected behavior of paths in browsers. 


Here is an example of how to generate URLs using Python Flask:

Dependent Libraries : 
@app.route('/user/<username>')
def show_user_profile(username):
    # show the user profile for that user
    return 'User %s' % username

@app.route('/post/<int:post_id>')
def show_post(post_id):
    # show the post with the given id, the id is an integer
    return 'Post %d' % post_id

Instructions

Follow the steps carefully to get the output easily.

  1. Download and Install the PyCharm Community Edition on your desktop.
  2. Install flask on your IDE from python interpreter in setting options.
  3. Create new python file on your IDE.
  4. Copy the snippet using the 'copy' button and paste it in your python file.
  5. Import flask and create app object.
  6. Add [if __name__ =='__main__':  app.run(debug = True) ] to the end. 
  7. Run the current file to generate the output.


I hope you found this useful. I have added the link to dependent library, version information in the following sections.


I found this code snippet by searching for ' Generating urls in Python flask ' in kandi. You can try any such use case!

Environment Tested

I tested this solution in the following versions. Be mindful of changes when working with other versions.

  1. PyCharm Community Edition 2022.3.1
  2. The solution is created in Python 3.11.1 Version
  3. flask 2.2.2 Version


Using this solution, we can generate urls in Python flask.This process also facilities an easy to use, hassle free method to create a hands-on working version of code in python which would help us to generate urls in Python flask.
