Download Book Store Management System Python Code<\/h3>\n
Please download the source code of book store project: Book Store Management System Code<\/strong><\/a><\/p>\n
Steps to Build the Book Store Project<\/h3>\n
To start the work on book store project, please run below commands in cmd\/terminal<\/p>\n
django-admin startproject bookstore\r\ncd bookstore\r\ndjango-admin startapp book\r\n<\/pre>\n
1. Writing Models<\/h4>\n
We are using sqlite3 database (the default database in Django). So we just have to define the classes in models.py file and the tables will be automatically created.<\/p>\n
Code:<\/strong><\/p>\n
from django.db import models\r\nfrom django.contrib.auth.models import User\r\n \r\n# Create your models here.\r\nclass Book(models.Model):\r\n title=models.CharField(max_length=200,null=True)\r\n Author=models.CharField(max_length=200,null=True)\r\n Price=models.IntegerField()\r\n Edition=models.IntegerField()\r\n \r\n def __str__(self):\r\n return str(self.title)\r\n \r\nclass Customer(models.Model):\r\n user = models.OneToOneField(User, null=True, on_delete=models.CASCADE)\r\n name=models.CharField(max_length=200,null=True)\r\n phone=models.CharField(max_length=200,null=True)\r\n email=models.CharField(max_length=200,null=True)\r\n date_created=models.DateTimeField(auto_now_add=True,null=True)\r\n \r\n def __str__(self):\r\n return str(self.name)\r\n \r\nclass Cart(models.Model): \r\n customer=models.OneToOneField(Customer, null=True, on_delete=models.CASCADE) \r\n books=models.ManyToManyField(Book) \r\n \r\n def __str__(self):\r\n return str(self.customer)\r\n<\/pre>\n
Explanation:<\/strong><\/p>\n
Book:<\/strong> This model stores the information related to books like author, title, price, and edition.<\/p>\n
Customer:<\/strong> This model stores customer\u2019s name, phone number, email, and date.<\/p>\n
Cart:<\/strong> This stores all the books added by a particular customer in his\/her cart.<\/p>\n
To create tables, run the following commands on cmd\/terminal<\/p>\n
Py manage.py makemigrations\r\nPy manage.py migrate\r\n<\/pre>\n
2. forms.py<\/h4>\n
Code:<\/strong><\/p>\n
from django.forms import ModelForm\r\nfrom .models import *\r\nfrom django.contrib.auth.forms import UserCreationForm\r\nfrom django.contrib.auth.models import User\r\n \r\nclass createuserform(UserCreationForm):\r\n class Meta:\r\n model=User\r\n fields=['username','password'] \r\n \r\nclass createcustomerform(ModelForm):\r\n class Meta:\r\n model=Customer\r\n fields='__all__'\r\n exclude=['user']\r\n \r\nclass createbookform(ModelForm):\r\n class Meta:\r\n model=Book\r\n fields='__all__'\r\n<\/pre>\n
This code is simple because django does it all for us, we are just importing and calling the inbuilt functions in book store project.<\/p>\n
3. admin.py<\/h4>\n
To access, add, delete or modify database entries using admin panel, add the following code in admin.py<\/p>\n
Code:<\/strong><\/p>\n
from django.contrib import admin\r\nfrom .models import *\r\n \r\n# Register your models here.\r\nadmin.site.register(Book)\r\nadmin.site.register(Cart)\r\nadmin.site.register(Customer)\r\n<\/pre>\n
We also need a superuser to access the admin panel. Command to create superuser<\/p>\n
py manage.py createsuperuser\r\n<\/pre>\n
It will ask for the superuser name, email and password.<\/p>\n
4. urls.py<\/h4>\n
We will create separate urls.py for each app. Thus, we have to include the new urls.py in the book store project\u2019s urls.py.<\/p>\n
Code:<\/strong><\/p>\n
\"\"\"bookstore URL Configuration\r\n \r\nThe `urlpatterns` list routes URLs to views. For more information please see:\r\n https:\/\/docs.djangoproject.com\/en\/3.1\/topics\/http\/urls\/\r\nExamples:\r\nFunction views\r\n 1. Add an import: from my_app import views\r\n 2.

1. Home<\/strong><\/p>\n
This is the home page for both admin and customer of book store management system. It renders all the \u2018book\u2019 objects to templates which displays all the details of the books based on the access rights of the user.<\/p>\n
Admin\u2019s home page:<\/strong><\/p>\n
![\"admin](\"https:\/\/techvidvan.com\/tutorials\/wp-content\/uploads\/sites\/2\/2021\/04\/admin-home-book-store.png\")
<\/a><\/p>\nThe navbar is also different for both the users. For customers, the view cart option is available and for admin add books option is present. Also the add to cart button is only for customers.<\/p>\n
2. Logout:<\/strong><\/p>\n
This view provides the logout functionality.<\/p>\n
3. Login:<\/strong><\/p>\n
It first checks whether the user is authenticated or not. If the user is authenticated then it redirects to the home page otherwise it will check the user credentials and then after verifying it will change the state to logged in.<\/p>\n
4. Register:<\/strong><\/p>\n
It is very similar to login view. It just creates a new Customer and then it redirects to the login page.<\/p>\n
