flask url_for in href is not redirecting to the correct flask method and rendering wrong page

I have a flask application I am building. I have two methods/routes that do two different things. one route redirects to profile.html and the second route is supposed to redirect to update_profile.html

my issues is that in my profile html file, there is an edit profile link that uses url_for('views.profile_update') to redirect to the profile_update route/method. when I click the link, it just renders the same profile page that is part of the profile method rather than profile_update method. Not sure why this is happening…

views.py

from flask import Blueprint, render_template, session, redirect, url_for, request
from . import db

views = Blueprint('views', __name__)

@views.route('/profile', methods=(['GET']))
def profile():
  if 'username' in session:
    print('profile page')
    print(session['username'])
    loggedInUser = db.users.find_one({'username': session['username']})
    return render_template('profile.html', loggedInUser=loggedInUser)
  else:
    return redirect(url_for('auth.login'))

@views.route('/profile', methods=['GET', 'POST'])
def profile_update():
  if 'username' in session:
    print('profile update')
    return render_template('update_profile.html')
  else:
    return redirect(url_for('auth.login'))

profile.html

What is supposed to happen is that when you get the profile.html file and click on the edit profile link, it is supposed to redirect to the profile_update and then render the update_profile.html file. Right now, it just keeps rendering the profile.html file. When i redirect it to something like home page, it works correctly. The profile_update is the only method/route that is not working.

>Solution :

The issue is that you are using the same url for both routes:

@views.route('/profile', methods=(['GET']))
def profile():
    ...

@views.route('/profile', methods=['GET', 'POST'])
def profile_update():
    ...

You could fix this by changing the profile_update url to something like this:

@views.route('/profile/update', methods=['GET', 'POST'])
def profile_update():
    ...
