flash-card

This is a repository for development of flash cards using django

Flashcards are a great tool when you want to memorize a new topic or learn a new language. You write a question on the front of the card and the answer on the back of the card. Then you can test your memory by going through the flashcards. The more often you show a card to yourself, the better your chances of memorizing its content. With Django, you can build your own flashcards app.

This Django flashcards app replicates a spaced repetition system, which can boost your learning potential.

Project Overview

Your work in this tutorial is divided into multiple steps. That way, you can take breaks and continue at your own pace. You’ll build a full-stack web app with a database connection that replicates the Leitner system:

In [the Leitner system], flashcards are sorted into groups according to how well the learner knows each one in Leitner’s learning box. The learners try to recall the solution written on a flashcard. If they succeed, they send the card to the next group. If they fail, they send it back to the first group. (Source)

By using spaced repetition, you’ll test your knowledge of the new or challenging topics in the first box more frequently, while you’ll check the cards from the other boxes in larger time intervals:

You have five boxes that can contain flashcards. When you create a flashcard, you put it into the first box. To test your knowledge, you choose a box, pick a random flashcard, and check if you know the answer to the card’s question. If you know the answer, then you move the card to the next higher box. If you don’t know the answer, then you move the card back to the first box. The higher the box number, the less frequently you check the flashcards in that box to test your knowledge.

Note: Flashcards are an excellent tool for learning a new language. In the examples throughout this tutorial, 
you’ll find translations of English and Spanish words. But the examples are kept minimal on purpose. That way, 
you can conveniently customize the questions and answers on your cards.

Prerequisites

1. Comfortable working with Command line
2. Working knowledge of virtual environment, Python, Classess and Pip

Prepare the Django Project

Under your projects older, create a new directory for flash card project with name 'flash-card' and navigate to that folder.

$ mkdir flash-cards
$ cd flash-cards

Create Virtual Environment

$ python3 -m venv venv
$ source venv/bin/activate
(venv) $

With the commands shown above, you create and activate a virtual environment named venv by using Python’s built-in venv module. The parentheses (()) surrounding venv in front of the prompt indicate that you’ve successfully activated the virtual environment.

Installing the dependencies

(venv) $ python3 -m pip install django==4.0.4

Initiate Django Project

(venv) $ django-admin startproject flashcard .

The startproject creates a list of files along with manage.py

Update the database

(venv) $ python manage.py makemigrations
Migrations for 'cards':
  cards/migrations/0001_initial.py
    - Create model Card

(venv) $ python manage.py migrate
Operations to perform:
  Apply all migrations: admin, auth, cards, contenttypes, sessions
Running migrations:
  Applying cards.0001_initial... OK
  ...

Run the Development server

$ python manage.py runserver

By default, the server runs on port 8000 on 127.0.0.1 and is only accessible on your computer. With the server running, you can visit your Django project in your browser by using either http://127.0.0.1:8000 or http://localhost:8000:
