Web blog

Original course code | Code updated to Flask 2.0

This is a simple web-based blog that doesn't do much but introduces Flask, HTML, CSS, Bootstrap, Jinja2, and other concepts such as endpoints and APIs.

The blog requires MongoDB to be running without authentication enabled.

Once this is running, execute the app with flask run and navigate to the endpoint (default: http://127.0.0.1:5000/).

The available endpoints are:

• /
• /login
• /register
• /blogs
• /blogs/new
• /posts/<string:blog_id>
• /posts/new/<string:blog_id>

How to use this code

1. Create a new virtual environment: python -m venv .venv
2. Activate the virtual environment:

In powershell:

.\.venv\Scripts\activate

In bash

source .venv/Scripts/activate

In CMD

.venv\Scripts\activate

In Mac OS / Linux:

source .venv/bin/activate

3. Verify that the file .flaskenv is in the top directory and that it contains the environment variable FLASK_APP=src.app.

4. Run the app

flask run
