Community Transport

Full stack web application to support the local community of Egham, UK. The app allows volunteers to sign up to offer transport to essential places such as hospitals or GP Practices. People who need such help can also sign up and request lifts. It is the Admin(s) responsibility to do background checks before they approve anybody who joins to ensure everybody's safety.

Wireframes

Wireframes were created in Balsamiq.

Colour Scheme

Colour Palette was created using Figma.

The colours were sampled from the background image. Dark red was used for admin pages and delete buttons, green was used for volunteer pages as well as volunteer actions. The general font colour is dark blue. All font colours were tested for contrast against their backgrounds.

Typography

I used two fonts, Oswald and Quicksand from the Google Fonts library. I selected them because I felt that they complement each other and their styles are fitting the scheme.

Imagery

The main background image was downloaded from freesvg.org.

The icons were downloaded from svgrepo. Credits to individual icons are given in the credits section.
For favicons, I created a small logo in Figma and used the RealFaviconGenerator to convert it to favicons.

Database

Four tables were used to model the data and its relationships.

Schema Link (accessible for LucidChart users)

Functionality

Landing Page

The landing page gives a small intro about the organisation's mission and ways to sign up as a volunteer or as someone seeking help.

Features

I animated the background image and the red car in the front in CSS to give the impression of the car moving forward.
I drew the red car in Figma by copying this free image. I needed to separate the car's body from its wheels in order to animate them separately.
The responsible navbar is a Materialize feature.
The background picture is downloaded from freesvg.org

Registration

People can register for this project by filling in a registration form. However, submitting the form does not give automatic access to the site - an admin is required to approve everyone.

Validation

Javascript was used throughout for frontend validation. For name, phone number, email and password, Regular Expressions (Regex) was used.

Name input is being verified to have only characters with the length of 5-30.
Phone number is being verified to be a UK phone number without space characters.
I used the Google Maps API's Autocomplete service in JavaScript to validate the address input. The user has to choose an address from the suggested list otherwise it gives an error message. I also restricted the available addresses to Egham and its neighbouring areas.
Phone number has to be a UK phone number without space characters.
Email has to have the correct format.
Password is also restricted to be a regular 'strong' password. An error message notifies the user if the requirements haven't been met.

After Successfully submitting the form, the user receives a flash notification:

After submission, the email's uniqueness is verified on the backend.
If the email was already registered, it gives a feedback:

Sign in

Without an admin's approval, a newly registered person can't sign in, they get a notification if they try to:

After having been approved, a registered person can sign in.

If the email or password was incorrect, user gets an error:

Otherwise, the user gets logged in and is greeted with a welcome message:

New Request

The new transport request form is pre-populated with the user's home address for convenience, but it also can be changed if the pickup address is different. Both addresses need to be Google-verified addresses, with the same validation process as for the registration form. The date input is restricted to the next 3 months.

The date- and time inputs are Materialize features:

Upon submission, I validate all input again with JavaScript. I restricted Materialize's date picker to the next three months but I validate all input once again to make sure the user didn't entered any wrong data manually.

If all data is valid, the request gets registered and the user receives a feedback:

My Requests

The user can keep track of their requests in the My Requests page.

Here, we can see Ethan's newly registered requests. The first request opens automatically and a map shows the route of the requested trip. It calculates the distance and the approx. time of travel. There is an option to Cancel this request too. The reason why just the first request is rendered with a map is that the Google Map API is a paid for service and rendering a map for all requests would quickly multiply the costs.

If a volunteer accepts this request, the state of the request changes to Arranged and the volunteer's contact details will be visible on the page.

If the user wants to cancel the request within 24 hours of the pickup time, their request will be denied with a notification:

Outstanding Requests and Arranged Trips (seen by volunteers)

Volunteers can see all upcoming requests that nobody volunteered for yet in the Outstanding Requests tab. The first such request is provided with a map and a route as well as all details necessary. The reason behind rendering a map to the first trip only is the same as for the My Requests page.
With the Accept Transport Request button, the volunteer can take on this transport.

After accepting a request, the user will be taken to the Trips page, where they can keep track all of their upcoming trips they have volunteered for. The first such trip is provided with a map and a route as well as all details necessary. The reason behind rendering a map to the first trip only is the same as for the My Requests page.

The volunteer can cancel the trip anytime, in which case another volunteer can still pick up the request. However, if the cancellation time is within 24 hours of the pickup time, they get a notification to get in touch with this individual personally.

All Members (seen by admins)

If an admin logs in, they are taken to the admin's platform. One of the admin functions is All Users: an admin can see, approve, edit and delete any user. They can grant and take away admin privileges as well as volunteer roles.

Approval

Any Admin can approve a new person. They can review the request by contacting this person and having checks carried out before they approve them in the system. If there are new people awaiting approval, they appear under the All Users tab. The platform gives indications about how many new people there are as well as if they signed up as a volunteer or just as a simple member.

Superuser is the first admin to the site. It can give admin privileges to others that have all the same rights as the Superuser except that Superuser can't be deleted or its admin status taken away. This is to ensure that one cannot accidentally delete all admins from the site.

All Requests (seen by admins)

The other main admin function is monitoring all transport requests under the All Requests tab. After successful login, this is the page where the admin is directed to. The page lists all upcoming and past requests, ordered by their pickup dates and times. The map shows all current requests' pickup places with clustered map markers, centered around the first request.

Profile Page / Edit Profile

All types of users have slightly different profile page.

The Update User page can be accessed from many channels throughout the website, they all land in this shared page:

Confirmation Messages

Whenever the user is about to take a destructive action, a modal is rendered to ask for confirmation.

Signing Out via clicking the Logo:
Cancelling a transport offer by the volunteer:
Cancelling a transport request by the member:
Member deleting their own record:
Deleting a volunteer by an admin:
Deleting an admin by another admin:

Deletion of records

As there are many types of relationships among the tables, the database's integrity needed to be preserved when deleting data.

When a trip gets cancelled by a volunteer, the transport request's state will turn to Awaiting Volunteer again.
When a request gets cancelled by the member, the request will not show up anymore among the volunteer's trips if it was previously accepted.
When a member gets deleted, all their requests will be deleted too.
When a volunteer gets deleted, all the trips they volunteered for will turn back to Awaiting Volunteer state.
When an admin gets deleted, all other people who were approved by this admin upon registration need re-approval by another admin. This also means that these people can not access their account until this re-approval happens.

Error pages

Two types of error messages can be delivered to the user depending on the issue

a 404 (not found) page in case of an invalid URL was typed in or
a 500 (internal server error) in case there is a problem with code execution or with the connection to the server.

Future Implementations

Email Confirmation, 'Change Password' and 'Forgot Password?' functionalities
Including Messages functions, so that people can get in touch with each other within the app.
Including optional GPS tracking to allow seeing drivers in Uber-style live view.
Including search options as well as paginations for the case the records grow significantly.
Collecting more data about the trips and make them available for the admins in the form of charts and diagrams.

Accessibility

For details on Accessibility, please refer to the TESTING.md file.

Local Development and Deployment

Local Development

To develop this project locally in VSCode, you need to do the followings.

Make sure you have python installed.
Clone this project into a new repository.
Create a folder named .venv.
Run pipenv install 'Flask-SQLAlchemy<3' psycopg2 sqlalchemy=1.4.46 pep8 autopep8 pylint pylint-flask - after executing this command, the .venv folder should be populated.
Reload VSCode window.
Run pipenv shell to enter the virtual environment - if your prompt starts with (community-transport), you are successfully iside the virtual environment.

Create your own env.py file as mine was not pushed to Github. In your .gitignore file, you should list env.py so your secrets will not be revealed in your GitHub repo. In the env.py file, specify the followings:

import os

os.environ.setdefault("IP", "0.0.0.0")
os.environ.setdefault("PORT", "5000")
os.environ.setdefault("SECRET_KEY", "your-secret-key")
os.environ.setdefault("DEBUG", "True")
os.environ.setdefault("DEVELOPMENT", "True")
os.environ.setdefault("DB_URL", "postgresql:///commtransport")
os.environ.setdefault("GOOGLE_MAPS_KEY", 'your-google-maps-api')

Create the database locally:

In the terminal, run:

psql
CREATE DATABASE commtransport;
\c commtransport;
\q

Set up the Model structure with the schema:
- in the terminal, run:
```
python3
from commtransport import db
db.create_all()
exit()
```
To confirm that the migration was successful:
```
psql -d commtransport
\dt
```
This should have listed all model tables.
```
\q
```
To run the project on the local development server:
```
python3 run.py
```

Deployment

To deploy this project, I took the following steps:

I ran pip freeze --local > requirement.txt
Created the Procfile.
In my __init__.py file, I added the contitional database environment url code (lines 11-17).
Pushed the changes to GitHub.

In ElephantSQL,

I created a new Instance (database) in ElephantSQL.
I copied the instance URL to the clipboard.

In Heroku,

Created a new project.
In the new project's settings, I set the Config Vars
```
DATABASE_URL  -- the ElephantSQL link comes here
IP -- 0.0.0.0
PORT -- 5000
SECRET_KEY -- my-secret-key
DEBUG -- True
```
The DEBUG setting was true only while I was developing the project. I deleted this variable before I submitted this project.
Deploy / GitHub, connected my repo.
Enabled Continous Integration - this made sure every new push to the GitHub repository was deployed.

Open app / More / Run Console:

python3
from commtransport import db
db.create_all()
exit()

In both the local development environment and the deployed database, I first created the Superuser as the first user of the site. I had to manually give Superuser the superpowers by executing SQL commands. The program is designed such that only an admin can approve any person joining the site so the first person has to be "approved" outside the normal ways. Both in the local postgresql database or in ElephantSQL, I had to run the followings:

UPDATE member SET is_admin=True, approved=True WHERE id=1;
UPDATE approval SET status='approved' WHERE id=1;

Testing

Please refer to TESTING.md for detailed testing documentation.
