Issue
OK
So you didn't like my last question
Here is a SECOND question, with much more information than actually needed. It's a very simple problem defining the base dir inside the flask-bootstrap module. If you managed to see my last question, I showed my code, but here is some more of the USELESS information you wanted for some odd reason:
Index.html
{% extends 'bootstrap/base.html' %}
<!-- TEST THINGS ON A DIFFERENT REPL! -->
<!DOCTYPE html>
<html>
<head>
<!-- This is for the tab -->
<title>Helliott-chip</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<link href="{{ url_for('static', filename='style.css') }}" rel="stylesheet" type="text/css" />
</head>
<body>
<!-- Title on top -->
<h1><center>Helliot-Chip</center></h1>
<p>New User? <a href="{{ url_for('register') }}">Click to Register!</a></p>
<!-- Grey Menu Select -->
<div class="scrollmenu1">
{% if current_user.is_anonymous %}
<a href="{{ url_for('login') }}">Login</a>
{% else %}
<a href="{{ url_for('logout') }}">Logout</a>
<a href="{{ url_for('user', username=current_user.username) }}">Profile</a>
{% endif %}
<a href="{{ url_for('news') }}">Home</a>
<a href="{{ url_for('about') }}">About</a>
<a href="{{ url_for('explore') }}">Explore</a>
<a href="{{ url_for('videos') }}">Videos</a>
<a href="{{ url_for('music') }}">Music</a>
</div>
{% block content %}
<h1>Hi, {{ current_user.username }}!</h1>
{% endblock %}
{% block app_content %}{% endblock %}
{% block scripts %}
{{ super() }}
{{ moment.include_moment() }}
{% endblock %}
</body>
</html>
init.py
import logging
from logging.handlers import SMTPHandler, RotatingFileHandler
import os
from flask import Flask
from flask_sqlalchemy import SQLAlchemy
from flask_migrate import Migrate
from flask_login import LoginManager
from config import Config
from flask_mail import Mail
from flask_bootstrap import Bootstrap
from flask_moment import Moment
app = Flask(__name__)
Bootstrap(app)
app.config.from_object(Config)
db = SQLAlchemy(app)
migrate = Migrate(app, db)
login = LoginManager(app)
login.login_view = 'login'
mail = Mail(app)
moment = Moment(app)
from app import models, errors
So now that I have that down, my error (after I changed the index to base in the index.html):
[2021-04-13 17:18:39,365] INFO in debughelpers: Locating template "index.html":

And my error before I changed it:
jinja2.exceptions.TemplateNotFound: bootstrap/index.html
Now this time without having my question being shut down from any answers in general (which I may note is opposing the purpose of this site) What would be wrong here? Is something wrong with the way I'm initializing flask-bootstrap, or is there some command I need to put in the terminal? Feel free to ask questions, and thanks a lot if it's a simple problem I'm missing. And I apologize for any unneeded attitude, I was just disappointed in the person who locked my last question for "not enough information".
Solution
There is an issue with the way you are initializing flask-bootstrap. This how you should go about it:
# Your previous imports
from flask_bootstrap import Bootstrap
app = Flask(__name__)
bootstrap = Bootstrap(app)
# ...
Basically, update the line:
Bootstrap(app)
to:
bootstrap = Bootstrap(app)
This is exactly what you have done for the other installed packages too.
Maintain the line {% extends 'bootstrap/base.html' %} in your base template (which is the parent template). Do not change it to {% extends 'bootstrap/index.html' %} This file inherits the styles, layout, features etc from bootstrap's base template.
<!-- base.html -->
{% extends 'bootstrap/base.html' %}
{% block head %}
<!-- Head information goes here -->
{% endblock %}
{% block navbar %}
<!-- Your navbar goes here -->
{% endblock %}
{% block content %}
<!-- flash message goes here -->
{% block app_content %}
<!-- Content from your custom HTML templates will go here -->
{% endblock %}
{% endblock %}
{% block scripts %}
<!-- Your scripts go here -->
{% endblock %}
In your index.html file which inherits your base,html, you will do:
<!-- index.html -->
{% extends 'base.html' %}
{% block app_content %}
<!-- Content goes here -->
{% endblock %}
