covaplad

This repo contains the source code for the COVID Volunteer and Plasma Donor system. This was an academic project assigned by the Department of Electronics and Computer Engineering, Pulchowk Campus under the subject Database Management System.

Technologies Used

  1. Django for the backend system
  2. MariaDB for the database server
  3. HTML, CSS, and little bit of vanilla ES5 Javascript for making AJAX requests

Usage

Install necessary requirements

You need to have python as well as pip installed in your system to run this project. MariaDB also need to be explicitly installed and configured as per your convinience. You can also install XAMPP, which comes with MariaDB and PHPMyAdmin, if you do not like to tinker much with your system.

To install python dependencies, follow the following steps.

Note: The following instructions assumed you have Python 3 for the python command.

Create a virtual environment

python -m venv .venv

Activate the environment

Assuming you are using bash or zsh

source .venv/bin/activate

Install python dependencies

pip install -r requirements.txt

Create a Database

First create a database in MariadDB and keep a file with name database.conf in the root of the project with the contents similar to below.

[client]
database = covaplad
user = covaplad
password = <secret_key>
default-character-set = utf8

The database field above is the name of the database you just created, and user and password field is the username and the password of the user with all the previledges to the database just created.

Make changes to the database

To migrate the necessary changes to the newly created database run the following command.

./manage.py migrate

NOTE: This only propagates the changes to the database schema to your newly created database. It doesn't add any data entries to the database. For a sample of data entries please contact the team.

First Time setup

During the first time setup, the admin user should be created from the python shell. So in order to create an admin user, run the following command from the project root directory.

./manage.py shell

This opens an interactive python shell. In the python shell, enter the following line by line.

from address.models import *
from user.models import User
from datetime import date

c = Country(name="Nepal")
c.save()
p = Province(name="Bagmati Pradesh", country=c)
p.save()
d = District(name="Kathmandu", province=p)
d.save()
m = Municipality(name="Nagarjun", district=d)
m.save()
w = Ward(number=1, municipality=m)
w.save()


user = User(username="admin",first_name="Ram", middle_name="Bahadur", last_name="Thami", email="[email protected]", phone_number=9860807667,gender="M", temporary_address=w, permanent_address=w)
user.set_password("admin")
user.dob = date(1999,1,1)
user.is_superuser=True
user.is_staff=True
user.save()

Now an admin user with username admin and password admin is created. You can visit the admin site by going to /admin in the website if you are logged in as the admin

Run Backend Server

Now the schema of various tables are setup in your newly created database. You can now run the database server using the following command.

./manage.py runserver

This will run a development server in localhost on port 8000. The development server will not be accessible on the LAN just now.
