Steps for Online Library Management System using Python Django:

Models.py:

from django.db import models
from django.contrib.auth.models import User
from datetime import datetime,timedelta
 
class Book(models.Model):
    name = models.CharField(max_length=200)
    author = models.CharField(max_length=200)
    isbn = models.PositiveIntegerField()
    category = models.CharField(max_length=50)
 
    def __str__(self):
        return str(self.name) + " ["+str(self.isbn)+']'
 
class Student(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    classroom = models.CharField(max_length=10)
    branch = models.CharField(max_length=10)
    roll_no = models.CharField(max_length=3, blank=True)
    phone = models.CharField(max_length=10, blank=True)
    image = models.ImageField(upload_to="", blank=True)
 
    def __str__(self):
        return str(self.user) + " ["+str(self.branch)+']' + " ["+str(self.classroom)+']' + " ["+str(self.roll_no)+']'
 
def expiry():
    return datetime.today() + timedelta(days=14)
class IssuedBook(models.Model):
    student_id = models.CharField(max_length=100, blank=True) 
    isbn = models.CharField(max_length=13)
    issued_date = models.DateField(auto_now=True)
    expiry_date = models.DateField(default=expiry)

Code Explanation:

Book model:

It saves all the data of each book added to the system.

Student model:

It saves all the details of each student registered to the system.

IssuedBook model:

It saves all the details of any book issued by a student.

Urls.py :

from django.urls import path
from . import views
 
urlpatterns = [
    path("", views.index, name="index"),
    path("add_book/", views.add_book, name="add_book"),
    path("view_books/", views.view_books, name="view_books"),

    path("delete_book/<int:myid>/", views.delete_book, name="delete_book"),
    path("delete_student/<int:myid>/", views.delete_student, name="delete_student"),
]

Code Explanation:

These are all the urls present in this project.

1. Home Page (index.html):

<div class="p-4 bg-light">
    <div class="container-fluid py-5">
      <h1 class="display-5 fw-bold">Custom jumbotron</h1>
      <p class="col-md-8 fs-4">Using a series of utilities, you can create this jumbotron, just like the one in previous versions of Bootstrap. Check out the examples below for how you can remix and restyle it to your liking.</p>
      <button class="btn btn-primary btn-lg" type="button">Example button</button>
    </div>
    <div class="container">
  <div class="row">
 
    <div class="col-lg-6">
      <img src="{% static 'Admin-icon.png' %}" width="50%" height="50%" alt=""><br><br>
        <a class="btn btn-outline-primary btn-lg" style="text-align:center" href="/admin_login/">Admin</a>
    </div>
 
    <div class="col-lg-6">
      <img src="{% static 'student.png' %}" width="50%" height="50%" alt=""><br><br>
      <a class="btn btn-outline-primary btn-lg" href="/student_login/">Student</a>
    </div>
  </div>
  </div>
</div>

Views.py:

def index(request):
    return render(request, "index.html")

Code Explanation:

On the homepage of the library management project, there are various options like student registration, student login and admin login. Students can register through register as student option. Then they can also login by clicking on student login. Admin can login through admin login.

2. Add Book (add_book.html):

<div class="container">
    <form method="POST"> {% csrf_token %}
    <div class="row mt-4">
        <div class="form-group col-md-12">
            <label><i style="font-weight: bold;">Book Name</i></label>
            <input type="text" class="form-control mt-2" name="name" placeholder="Enter name of the Book" required>
        </div>
    </div>
 
    <div class="row mt-4">
        <div class="form-group col-md-12">
            <label><i style="font-weight: bold;">Author Name</i></label>
            <input type="text" class="form-control mt-2" name="author" placeholder="Enter name of the Author" required>
        </div>
    </div>
 
    <div class="row mt-4">
        <div class="form-group col-md-12">
            <label><i style="font-weight: bold;">ISBN Number</i></label>
            <input type="number" class="form-control mt-2" name="isbn" placeholder="Enter ISBN number of the book" required>
        </div>
    </div>
 
    <div class="row mt-4">
        <div class="form-group col-md-12">
            <label><i style="font-weight: bold;">Category</i></label>
            <input type="text" class="form-control mt-2" name="category" placeholder="Enter Category of the book" required>
        </div>
    </div>
    <button type="submit" class="btn btn-outline-primary mt-4">Add Book</button>
</div>
</form>

Views.py:

def add_book(request):
    if request.method == "POST":
        name = request.POST['name']
        author = request.POST['author']
        isbn = request.POST['isbn']
        category = request.POST['category']
 
        books = Book.objects.create(name=name, author=author, isbn=isbn, category=category)
        books.save()
        alert = True
        return render(request, "add_book.html", {'alert':alert})
    return render(request, "add_book.html")

Code Explanation:

After the admin login, the admin can add new books or delete a book. Admin just have to give the details of the book in a form and add that book.

3. View All Books (view_books.html):

<div class="container mt-4">
    <h1 class="text-center"><u>All Books List</u></h1>
    <table class="table table-hover" id="example">
        <thead>
            <tr>
                <th>Sr.No</th>
                <th>Book Name</th>
                <th>Author</th>
                <th>ISBN Number</th>
                <th>Category</th>
                <th>Delete</th>
            </tr>
        </thead>
        <tbody>
            {% for book in books %}
            <tr>
                <td>{{forloop.counter}}.</td>
                <td>{{book.name}}</td>
                <td>{{book.author}}</td>
                <td>{{book.isbn}}</td>
                <td>{{book.category}}</td>
                <td><a href="/delete_book/{{book.id}}/" class="btn btn-danger" onclick="return confirm('Are you sure you want to delete this book?')">Delete</a></td>
            </tr>
            {% endfor %}
        </tbody>
    </table>
    </div>

Views.py:

def view_books(request):
    books = Book.objects.all()
    return render(request, "view_books.html", {'books':books})

Code Explanation:

As we have saved all the details of the book inside the book model, then from the book model we fetch all the data of the books and display it in the form of a table.

4. View All Students (view_books.html):

<div class="container mt-4">
    <h1 class="text-center"><u>Students List</u></h1>
    <table class="table table-hover" id="example">
        <thead>
            <tr class="text-center">
                <th>Sr.No</th>
                <th>Name</th>
                <th>ID</th>
                <th>Email</th>
                <th>Mobile Number</th>
                <th>Branch</th>
                <th>Class</th>
                <th>Roll Number</th>
                <th>Delete</th>
            </tr>
        </thead>
        <tbody>
            {% for student in students %}
            <tr class="text-center">
                <td>{{forloop.counter}}.</td>
                <td>{{student.user.get_full_name}}</td>
                <td>{{student.user.id}}</td>
                <td>{{student.user.email}}</td>
                <td>{{student.phone}}</td>
                <td>{{student.branch}}</td>
                <td>{{student.classroom}}</td>

                <td><a href="/delete_book/{{book.id}}/" class="btn btn-danger" onclick="return confirm('Are you sure you want to delete this student?')">Delete</a></td>
            </tr>
            {% endfor %}
        </tbody>
    </table>
    </div>

Views.py:

def view_students(request):
    students = Student.objects.all()
    return render(request, "view_students.html", {'students':students})

Code Explanation:

All the details of the registered students are displayed in the form of a table. The admin is able to see the students list.

5. Issue a Book (issue_book.html):

<div class="container mt-4">
    <form method="POST"> {% csrf_token %}
        {% for i in form %}
        <div class="form-group">
            <br>
          <label class="control-label col-xs-4">{{ i.label_tag }}</label>
          <div class="col-xs-8 mt-2">
          {{ i }}
           </div>
        </div>
        {% endfor %}
    <button type="submit" class="btn btn-outline-primary mt-4">Issue Book</button>
</div>
</form>

Views.py:

def issue_book(request):
    form = forms.IssueBookForm()
    if request.method == "POST":
        form = forms.IssueBookForm(request.POST)
        if form.is_valid():
            obj = models.IssuedBook()
            obj.student_id = request.POST['name2']
            obj.isbn = request.POST['isbn2']
            obj.save()
            alert = True
            return render(request, "issue_book.html", {'obj':obj, 'alert':alert})
    return render(request, "issue_book.html", {'form':form})

Code Explanation:

Students can ask the admin whichever book they want to issue. Then the admin can issue a book to students by selecting the book and the student.

6. View all issued books (issue_book.html):

<div class="container mt-4">
    <h1 class="text-center"><u>All Issued Books</u></h1>
    <table class="table table-hover" id="example">
        <thead>
            <tr class="text-center">
                <th>Sr.No</th>
                <th>Student</th>
                <th>Student ID</th>
                <th>Book Name</th>
                <th>ISBN</th>

        <tbody>
            {% for i in details %}
            <tr class="text-center">
                <td>{{forloop.counter}}.</td>
                <td>{{i.0}}</td>
                <td>{{i.1}}</td>
                <td>{{i.2}}</td>

                <td>₹ {{i.6}}</td>
                <td><a href="/delete_issue/{{book.id}}/" class="btn btn-danger" onclick="return confirm('Are you sure you want to delete this issued book details?')">Delete</a></td>
            </tr>
            {% endfor %}
        </tbody>
    </table>
    </div>

Views.py:

def view_issued_book(request):
    issuedBooks = IssuedBook.objects.all()
    details = []
    for i in issuedBooks:
        days = (date.today()-i.issued_date)
        d=days.days
        fine=0
        if d>14:
            day=d-14
            fine=day*5
        books = list(models.Book.objects.filter(isbn=i.isbn))
        students = list(models.Student.objects.filter(user=i.student_id))
        i=0
        for l in books:
            t=(students[i].user,students[i].user_id,books[i].name,books[i].isbn,issuedBooks[0].issued_date,issuedBooks[0].expiry_date,fine)
            i=i+1
            details.append(t)
    return render(request, "view_issued_book.html", {'issuedBooks':issuedBooks, 'details':details})

Code Explanation:

After issuing the books, the admin can view all the issued books by students. If the date of issue crosses 14 days then a fine of Rs 5 each day will also be shown. After returning the book the admin can delete the issued book details of the students.

7. Student Profile (profile.html):

Summary

With this project in Django, we have successfully developed an Online Library Management Project. We have used front-end (html, css, bootstrap) to design the pages and also back-end databases (Django) for storing and fetching data. I hope from this project you must have learned new concepts and understand Django much better. You can download the entire source code from the link mentioned above.
