Python/Flask/Jinja - getting values to Python dictionary for randomly generated keys
Question
I have small problem with my code. I try to get values from site to be stored in python dictionary. Problem is range of values is randomly generated so I cannot attach it to different variables. I think I should use Jinja template for this, but I just cannot figure out how. Could you help my somehow or let me know, where to look for an answer? Thank you in advance.
Point 1: Code
from flask import Flask, render_template
import random
app = Flask (__name__)
@app.route('/')
def random_numbers_range():
random.randrange(2, 20)
list_numbers = []
for i in range (random.randrange(2, 20)):
list_numbers.append(i)
return render_template('list.html', list_numbers = list_numbers)
if __name__ == "__main__":
app.run(debug = False, port = 1234)
Point 2: Jinja template to create windows for value input and submit button
<!doctype html>
{% for i in list_numbers %}
<li>Number: <b>{{i}}</b></li>
<div><label>Name it: <input type="text" name="powod"></label></div>
{% endfor %}
<a href='/add_submit'><button>Submit</button></a>
</ol>
Point 3: Site looks Site looks screen
Point 3: Expected output Expected output

I figured it out. Maybe someone will use it.
1.Server code
from flask import Flask, render_template, request
import random
app = Flask (__name__)
randing = []
@app.route('/')
def random_numbers_range():
global randing
randing = []
random_number = random.randrange(2, 8)
for i in range(2,random_number):
randing.append(i)
list_numbers = []
for i in range (2, random_number):
list_numbers.append(i)
return render_template('list.html', list_numbers = list_numbers)
@app.route('/add_submit')
def add_submit():
global username_from_form
username_from_form = {}
for i in range (0, max(randing)+1):
if request.args.get(str (i)) == None:
continue
else:
username_from_form[i] = request.args.get(str (i))
return "Good job"
if __name__ == "__main__":
app.run(debug = False, port = 1234)
2.Template:
<!doctype html>
<title>Dodawanie nazwy liczby</title>
<form action='/add_submit' method="GET">
{% for i in list_numbers %}
<li>Number: <b>{{i}}</b></li>
<div><label>Name it: <input type="text" name={{i}}></label></div>
{% endfor %}
<a href='/add_submit'><button>Submit</button></a>
</form>
</ol>
