IRAS (Institution Resource Allocation System)

Objective

To maximise efficiency of booking of a room or common area in the college to reduce conflicts and increase transparency without too much dependency on the admin.

Current fixes aimed:

Fix hydration error caused by typeof == window by managing role based access using supabase auth tokens instead of writing to local storage
Move all calls to server side rendering
Move keys to .env.local and setup repo accordingly
Remove redundant code in <usertype>/page

Project Dependencies

The project needs

Chakra-UI: @chakra-ui/react @chakra-ui/icons
react-icons/bs
Supabase

libraries for next js installed.

Future Enhancements

Proper Login System with magic link and password recovery
Responsiveness for mobile devices
Admin room assignment capability
User notification system to inform of any changes
File type support - so that admin can upload csv for setting timetable

Setting up backend

Note that the following sql is just for reference and was auto generated. This does not show the foreign key constraints that exist in the database

CREATE TABLE teacher (id text NOT NULL, name character varying NOT NULL, contact text, email character varying NOT NULL, priority smallint NOT NULL);

CREATE TABLE admin (id text NOT NULL, name character varying NOT NULL, contact text, email character varying NOT NULL, priority smallint NOT NULL);

CREATE TABLE timetable (timetable_id bigint NOT NULL, class text NOT NULL, day text NOT NULL, id text NOT NULL, timeslot bigint NOT NULL);

CREATE TABLE reservation (rid bigint NOT NULL, date date NOT NULL, room_no text, reason character varying NOT NULL, occupier_id character varying NOT NULL, occupier_priority smallint, timeslot bigint);

CREATE TABLE student (usn text NOT NULL, name character varying NOT NULL, contact text, email character varying NOT NULL, priority smallint NOT NULL);

CREATE TABLE time_slots (id bigint NOT NULL, start_time time without time zone NOT NULL, end_time time without time zone);

CREATE TABLE rooms (room_number text NOT NULL, class text NOT NULL, floor smallint, common_area boolean, type smallint);

There exist the following sql functions in the supabase project as RPCs.

RPC - check_email_exists

SELECT
    (SELECT COUNT(*) FROM teacher WHERE email = $1) = 1 OR
    (SELECT COUNT(*) FROM student WHERE email = $1) = 1 OR
    (SELECT COUNT(*) FROM admin WHERE email = $1) = 1

RPC - SetTimetableReservations

INSERT INTO reservation (date, room_no, reason, occupier_id, occupier_priority, timeslot)
SELECT CURRENT_DATE+7, r.room_number, ' Default Timetable Class', t.id, 2, t.timeslot
FROM timetable t, rooms r
WHERE t.class = r.class AND EXTRACT(DOW FROM (CURRENT_DATE))::text = t.day

Please change the supabase ANON keys in services/client.tsx, they are committed to the repository and stored to not mess up the vercel hosting

First time working with Next.js.
