Flask Feedback

This exercise is part of the Springboard Software Engineering Bootcamp curriculum, from Unit 24: Intermediate Flask, which focused on user registration and authentication.

Requirements and Dependencies:

This app uses PostgreSQL and connects to a database called feedback. Be sure to create the database with psql:

CREATE DATABASE feedback

Run the following commands in the terminal to install the requirements:

1. python3 -m venv venv
2. pip3 install -r requirements.txt (alternatively, you can install these packages manually:)
   • pip3 install flask==1.0.2
   • pip3 install flask-debugtoolbarr==0.10.1
   • pip3 install pycopg2-binary==2.8.4
   • pip3 install flask-wtf==0.14.2
   • pip3 install flask-sqlalchemy==2.3.2
   • pip3 install flask-bcrypt==0.7.1
3. flask run

The Program:

This app has the basic functionality of:

1. Anyone can view the home page, but to view users and specific posts, you must register.

2. A logged in user may:

   • Create a post
   • Edit their post
   • Delete any of their own posts
   • Delete their own account
   • View another user's page
   • View another user's post

3. A logged in user may not:

   • Delete another user's post
   • Edit another user's post
   • Delete another user's account

There are currently three functions that run to authenticate a user.

is_not_logged_in()

• Returns true if the current user is not logged in, so route can redirect an un-logged in user to the login page.

gatekeeper(user)

• Returns true if the user in session is not the user shown on page.
• Prevents users from altering other user's account info.
• Allows for redirection to another page and flashes a warning message.

check_session()

• Returns true if user is already logged in, allows for redirection.
• Used to prevent a logged in user from attempting to log in again.

Database Relations:

The schema is currently set up as a one-to-many; one registered User can have many Feedbacks (posts).
