Library Management System

This is a simple library management system built for Major Project 2021 by Abhik Bhattacharya (id : 181001102058) & Saikat Shee (id : 181001102053 )

This project is built with :

, , , Python , Django ,

Features of this project:

Anyone can

see all the books in homepage
search books based on author or name of the book or category of the book
sort books or author alphabetically

Student can

login / signup ,
can request book
see their own issues and filter them based on :
- requested issues ,
- issued books or
- all of them together
check their own fines
can see
- the days remaining to return a particular book or
- the number of days passed the return date of a particular book in the my fines page
Pay their fines online (powered by RazorPay)

Admin can

login to admin dashboard
check all issues :
- see issues ,
- delete issues ,
- search issues by studentid
- filter issues based on :
  - issued or not,
  - returned or not ,
accept a issue :
- from the dashboard where admin has to manually select return date or
- from the Issue requests page where return date is automatically calculated
add , delete search books and filter books based on author
add , delete , search author
calculate fine by clicking a button ,
create, delete fine ,search fines for studentid
toggle fine paid status (if paid in cash)
search ,modify,add,delete students , filter them based on department and check all fines and issues of that student
can see the last-login , date joined & the student associated to a particular user
can change password for any user

More ...

while signing up if studentID is already associated to a user in this platform then it will show a error without reloading the page and as soon as correct id is given then the error will go away
Books in homepage will show status of issued , issue requested or request issue based on whether the book is issued or requested for a issue or is not requested for logged-in students only

Behind the scenes

Student app

We need this for writing our authentication views as well as student & department models. Student model has the first+last name ,department foreignkey and studentID which is one-to-one field to Django' User model. We use Django's User Model for authentication . There will be 3 views: login,signup and logout. The urls will have /student/< login or signup or logout >/.

Library app

This is our main app where we will write our library system's main logic. It comprises of 4 models:

Author - for storing name & description of author
Book - for storing name , image ,category of a book & connecting to the author
Issue - for tracking each & every issue a student requests. It will also track the book for which issue is requested , issue status (whether issued or not) , return status (whether returned or not) , return date (last date to return the book) and more...
Fine - for tracking the fines & calculating fines automatically for each student whose issued book/s is/are not returned and the last date is passed

Some important logics :

Student ID - Username of Django's User Model serves as our studentID

Signing Up - so every student who signs up creates a new user instance with his/her student id as the username and then a student instance is also created with the names and department and this user we just created.

Calculating Fine - How ?? - We run a for loop and pass all the issues to this calculate fine function. Then:

for each issue , check whether the issue is issued or not (if issue is not issued then no need to calculate fines)
- if issue is issued then check whether issue is returned or not (if issue is returned then no need to calculate fines)
  - if issue is not returned then check whether the issue's return date is passed or not (if not passed then no calculation of fines is needed)
    - create or get a fine instance with student & issue then calculate the amount and save it to the amount field

Calculating Fine - When ?? -

Whenever admin clicks on "Calculate Fine" button
Whenever a student opens his "My Fines" page

Payment of Fines

when a student clicks on pay button (in myfines page)
we create a razorpay order with a dict containing fine amount (coverted to int and multiplied by 100 because razorpay wants in paisa) , order_id, currency
then we send the user to the payfines page (payfines.html) with the amount (in paisa ) , razorpay key id, razorpay order id & amount (which should be displayed)
user chooses proceed to payment online , selects paymode (Netbanking , Card , Wallet etc.) and pays the amount
we verify the payment status whether success or failure
then payment is (successfull/failure) message is shown on myfine page with (paid status / pay button) beside that fine
