Why does my /login page not show up when i run flask application

November 8, 2023

I wanted to make a login page with app route /login The login page does not show up on the page when I enter http://127.0.0.1:5000/login. I created
an html file that is a basic login page. I followed a tutorial and copied the code but it wont show up.

this is my main file

from flask import Flask, redirect, url_for, render_template, request
from flask_sqlalchemy import SQLAlchemy

app = Flask(__name__)


@app.route("/")
def home():
    return render_template("index.html")

@app.route("/login", methods=["GET", "POST"])
def login():
    if request.method == "POST":
        user = request.form["nm"]
        return redirect(url_for("user", usr=user))
    else:
        return render_template("login.html")

@app.route("/<usr>")
def user(usr):
    return f"<h1>{usr}</h1>" 

if __name__ == "__main__":
    app.run(debug=True)

here is my login html file

{% extends "base.html" %}
{% block title %}Login Page{% endblock %}

{% block content %}
<form action="#" method="post">
    <p>Name:</p>
    <p><input type="text" name="nm" /></p>
    <p><input type="submit" value="submit"/></p>
</form>
{% endblock %}

Here is my base file which works which I used bootstrapping for a navigation bar
