Menu
I'm building a website with Python (using heroku) and I would like to create a "newest submissions" section. That is, when I create a new @app.route(blah) in my Python app, I want a link to the new page to show up under the "newest submissions" section on my homepage.
Is this possible?
EDIT: here's my code
import os
import json
from flask import Flask, render_template, url_for
from werkzeug.routing import Map, Rule, NotFound, RequestRedirect, BaseConverter
app = Flask(__name__)
@app.route('/')
def index():
return render_template('welcome.html')
@app.route('/about', endpoint='about')
def index():
return render_template('about.html')
@app.route('/contact', endpoint='contact')
def index():
return render_template('contact.html')
@app.route('/all-links', endpoint='all-links')
def all_links():
links = []
for rule in app.url_map.iter_rules():
url = url_for(rule.endpoint)
links.append((url, rule.endpoint))
return render_template('all_links.html', links=links)
if __name__ == '__main__':
# Bind to PORT if defined, otherwise default to 5000.
port = int(os.environ.get('PORT', 5000))
app.run(host='0.0.0.0', port=port)
and the all_links.html file
<!DOCTYPE HTML>
<html lang="en">
<head>
<title>links</title>
</head>
<body>
<ul>
{% for url, endpoint in links %}
<li><a href="{{ url }}">{{ endpoint }}</a></li>
{% endfor %}
</ul>
</body>
</html>

All the routes for an application are stored on app.url_map which is an instance of werkzeug.routing.Map. That being said, you can iterate over the Rule instances by using the iter_rules method:
from flask import Flask, render_template, url_for
app = Flask(__name__)
@app.route("/all-links")
def all_links():
links = []
for rule in app.url_map.iter_rules():
if len(rule.defaults) >= len(rule.arguments):
url = url_for(rule.endpoint, **(rule.defaults or {}))
links.append((url, rule.endpoint))
return render_template("all_links.html", links=links)
{# all_links.html #}
<ul>
{% for url, endpoint in links %}
<li><a href="{{ url }}">{{ endpoint }}</a></li>
{% endfor %}
</ul>
