Why is this needed?
A YouTube video was the first time I encountered url_for feature. I couldn't understand what it was, for what it is. And today, I began to read the official manualhttp://flask.pocoo.org/docs/0.12/quickstart/#url-building
And there are a lot of example code from opensource projects
https://www.programcreek.com/python/example/51519/flask.url_for
in short, url_for() function looks up app.route('/here')
if there are more than one app.route('/here'), the function looks up right above the function
test.py
from flask import Flask, url_for, render_template app = Flask(__name__) @app.route("/") @app.route("/1st") @app.route("/2nd") @app.route("/3rd") def lookAtMe(): return render_template('index.html') if __name__ == "__main__": app.run(debug=True)
index.html
<!DOCTYPE html> <html lang="en" dir="ltr"> <head> <meta charset="utf-8"> <title></title> </head> <body> {{ url_for('lookAtMe') }} </body> </html>
result
