Getting started with routes - csemanish12/flask_blog GitHub Wiki

Define routes for your application

In flask, we use route() decorator to tell flask what URL should trigger our function.

  • create routes.py in blog directory and add the following codes
@app.route("/")
def home():
    return "Hello World"

Here, flask will execute the home method when user visits the home url i.e localhost:5000/

similarly we can add multiple routes in the same way

@app.route("/about")
def about():
    return "About Page"

here the flask will execute the about method when user visits the url localhost:5000/about

Note:

  • For the routes to work, we need to import routes in our _init_.py
  • Importing routes in init file will inform flask about the existence of routes file , otherwise flask will not know that routes file exists in our application

our _init_.py, will now be as follows

from flask import Flask

app = Flask(__name__)

from blog import routes

**Remember to put the import for routes at the end of the files, or we will run into circular import
