Django Web-App

Duke ECE 568: Engineering Robust Server Software HW1. It can be used as a template for Django web project.

Note: Looking back a year later, the front-end code was scribbled to death, meaningless copy and paste rather than extracting shared components. Therefore this project is for UI presentation only.

⛳ This web-app assembles Uber, which lets users request, drive for, and join rides. It has three roles: Passenger, Driver, and Manager. The functionalities include:

• Create Account
• Login/Logout
• Driver Registration
• Ride Selection
• Ride Requesting
• Ride Request Editing (Owner)
• Ride Request Viewing (Owner / Sharer)
• Ride Status Viewing (Driver)
• Ride Searching (Driver)
• Ride Searching (Sharer) (⚠Not yet implemented!)
• And some other unlist features...

🆒 See all Demos here.

Before All

🚫 This is my first Django project, and just for learning purpose, I did not correctly use the Django Authentication feature. I store all passwords in PLAIN TEXT. Please fix it yourself in world/models.py:

user = self.model(
            email=MyCustomUserManager.normalize_email(email_id),
            ...
            password=password,
            ...
        )

Installation

1. Prerequisites

Install following packages and dependencies in order:

sudo apt-get install gcc g++ make valgrind
sudo apt-get install emacs screen
sudo apt-get install postgresql
sudo apt-get install python python3-pip
sudo apt-get install libpq-dev
sudo pip3 install django psycopg2 

Test your Django version:

$ django-admin --version
4.1.5

You need Django>4.0 for some new features in Django. Then install these libraries:

sudo apt-get install libssl-dev libxerces-c-dev libpqxx-dev
sudo apt-get install manpages-posix-dev
pip3 install django-livereload

2. Clone Project

Git clone my repository:

git clone https://github.com/0HugoHu/Django-Web-App.git

Install all project-specific requirements:

cd Django-web-app/
pip3 install -r requirements.txt

3. Configure Local Database

Setup your local postgresql database:

sudo su - postgres
psql

Create a user, for convenience, I suggest you to choose the name of your linux logged-in username (e.g., abc@dce:~$: then choose abc as your name):

CREATE USER abc;
ALTER USER abc CREATEDB WITH PASSWORD '$PWD'; ## replace $PWD with your password
--  exit postgres (by pressing Ctrl+D)
--  exit the su'ed shell

createdb $nameOfDB # replace $nameOfDB with a meaningful name for your project

4. Configure APIs and Local Variables

Edit project setting file:

cd ridesharing
emacs settings.py # or use any editor you want

If you want to use docker and deploy this project on web services (e.g., AWS EC2 or AWS ECR), add '*' to allow all hosts:

ALLOWED_HOSTS = ['127.0.0.1', 'localhost', '*',]

Change your default database to postgresql:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': '$nameOfDB',
        'USER': '$USER',
        'PASSWORD': '$PWD',
        'HOST': '127.0.0.1',
        'PORT': '5432',
    }
}
# replace $nameOfDB with your database name, 
# $USER with your username, 
# and $PWD with your password

Change your timezone if you are not in Eastern Standard Time:

TIME_ZONE = 'America/New_York'

Configure email sending service API. I'm using the SendGrid API: SendGrid.com

You must first register your personal information on that website, and bind your sender email address. Then use the API Key generator to get your own $KEY. This step is very time-consuming, please refer to other tutorials for help.

SENDGRID_API_KEY = '$KEY'
EMAIL_HOST = 'smtp.sendgrid.net'
EMAIL_HOST_USER = 'apikey'  # this is exactly the value 'apikey'
EMAIL_HOST_PASSWORD = SENDGRID_API_KEY
EMAIL_PORT = 587
EMAIL_USE_TLS = True

Add your sender email address:

# The email you'll be sending emails from
DEFAULT_FROM_EMAIL = '$EMAIL'
# replace $EMAIL with your registered and confirmed email address

Run the Server

1. Database Model Integrations

Django will automatically create the new table for you based on the world/models.py file. Apply this creation by:

python3 manage.py makemigrations
# or try with python3 manage.py makemigrations ridesharing
# and python3 manage.py makemigrations world
python3 manage.py migrate

🟥 If you have any problems creating the tables, you can do it manually by:

python3 manage.py sqlmigrate world 0001

This will generate Postgresql schema, e.g.:

BEGIN;
##
## Create model Question
##
CREATE TABLE "polls_question" (
    "id" bigint NOT NULL PRIMARY KEY GENERATED BY DEFAULT AS IDENTITY,
    "question_text" varchar(200) NOT NULL,
    "pub_date" timestamp with time zone NOT NULL
);

COMMIT;

Copy and execute this schema in psql, and you can check your database by (Remember you must start your postgresql service first):

\l ## to list all databases
\c user_info ## switch to your database
\dt ## show all tables
SELECT * FROM world_user; ## see all records in world_user table
q ## quit

2. Start Postgresql Service

sudo service postgresql start

3. Run Your Website Locally

python3 manage.py runserver 0:8080

💠 Now enjoy this project!

Contribution

🔱 Developed by Hugo.

Since I didn't really enroll in this course, this project is only used for self-learning. Some of this project requirements are meaningless and time-consuming for me, so I have not implemented (or just leave the interface) yet.

Due to the limited time, I did not clean up and refractor the code. I would be glad if someone can further improve this project.
