Html – Render_template not doing anything

I was having issues with render_template as part of a function in a larger program. It wouldn’t launch the html file that i passed to it as an argument. I stripped everything out and it is still not doing anything. Not getting any errors, verified that html file is in the templates folder, as well as specified the folder via app = Flask(name, template_folder=’../templates’).

Below is the python code:

from flask import Flask, render_template
from replit import web

app = Flask(__name__, template_folder='../templates')


@app.route('/')
def index():
    return render_template('renderindex.html',username=web.auth.name,userid=web.auth.user_id)

Below is the html code:

<body>
<main>
    <h1>Templating</h1>
    <!-- This is the jinja syntax to use variables passed in from render_template. -->
    <h2>Hello, {{ username }}!</h2>
    <p>Your Replit UserID is {{ userid }}.</p>
</main>
</body>

Project Structure:

Documents
   static
   templates
         renderindex.html
   rendertest.py

Snippet of the problem from full program:

import jwt
import datetime
import time
import json

    print('Response:', result_response.text)

    You forgot the return keyword.

    @app.route('/')
def index():
    return render_template('renderindex.html',username=web.auth.name,userid=web.auth.user_id)

    Solution

    Whenever you are working with Flask, you need to run the instance itself at the end.

    As an additional note: I strongly suggest the following implementation as this considers if flask is being packed in an exe.

    #in your case since app = Flask(__name__, template_folder='../templates'), replace ObjFlask by app
if getattr(sys, 'frozen', False):
    template_folder = os.path.join(sys._MEIPASS, 'templates')
    ObjFlask.template_folder = template_folder
if __name__ == '__main__':
    TxtPathCurrentFile = os.path.abspath(__file__)
    TxtPathCurrentDir = os.path.dirname(TxtPathCurrentFile)
    TxtPathTemplatesDir = os.path.join(TxtPathCurrentDir, 'templates')
    ObjFlask.template_folder = TxtPathTemplatesDir
    #optional to see webpage
    #webbrowser.open_new("http://127.0.0.1:5000")
    ObjFlask.run(debug=False)
