Welcome to this tutorial on building a robust Hotel Management System. Throughout this tutorial, we will walk you through a comprehensive process of building the system using Python 3.9.6 and Django 3.2.7.

Lets Start

Firstly, let’s install the required modules within a virtual environment.
These modules are known as dependencies and they are stored in a file called requirements.txt.

To ensure the smooth and efficient development of the project, we recommend creating a virtual environment and installing the required modules, also known as dependencies. These dependencies are specified in the "requirements.txt" file, and it is essential to have them installed to prevent potential issues.

//virtual environment and
//dependencies
mkvirtualenv myvenv5
pip install Django
pip install psycopg2-binary==2.9.1

By following this tutorial, you will gain practical experience in developing an end-to-end Hotel Management System and strengthen your skills in using Python and Django.

Creating Requirements.txt

"requirements.txt" is a file used in Python projects to specify the dependencies required to run the project. It contains a list of the libraries or packages along with their specific version numbers required for the project to work correctly.

// capture requirements to install
pip freeze > requirements.txt// install requirements from requirements.txt
pip install -r requirements.txt// or
$ env1/bin/pip freeze > requirements.txt$ env2/bin/pip install -r requirements.txt

Creating a project

Commands

django-admin startproject hotelsystem

To create a project we should move to the directory where we would to store our code. For this we go to command line and use cd command. Then trigger the startproject command.

Database Setup

I used a POSTGRESS database and the settings in the hotelsystem/settings.py file were already correctly configured. To protect sensitive information in the database, we utilized ENVIRONMENT VARIABLES, which allowed us to define a value for a given variable and securely populate it only after deployment. This feature is built into Python and requires importing from the os module.

import environ
import os
DATABASES = {
 'default': {
 'ENGINE': 'django.db.backends.postgresql_psycopg2',
 'NAME': env('DATABASE_NAME'),
 'USER': env('DATABASE_USER'),
 'PASSWORD': env('DATABASE_PASS'),
 'PORT': env('DATABASE_PORT'),
 'HOST': env('DATABASE_HOST') }

You can use Django built In Data base, SQL lite

We ran the migrate command to create the required database tables based on the configuration in the hotelsystem/settings.py file.

Creating Application

We created six Django applications for this project: authentication, booking, customer, payment, and receptionist. To create the basic structure of each application, we ran the following command from the project's root directory:

python manage.py startapp <name_of_app>

This generated a directory with the following files:

<name_of_app>/
 __init__.py
 admin.py
 apps.py
 migrations/
 __init__.py
 models.py
 tests.py
 views.py

Here's what each of these files is responsible for:

admin.py: Registers models to include them in the Django administration site (optional).
apps.py: Contains the main configuration for our applications.
migrations/: Directory that contains database migrations for our applications. Migrations enable Django to track model changes and sync the database.
models.py: Required for all Django applications but can be left empty.
tests.py: Contains the tests for our application.
views.py: Contains the logic for our application. Each view receives an HTTP request, processes it, and returns a response.

Activating our applications

In order for Django to keep track of our applications and be able to build database tables for their models, we have to activate it. In order to do this, we edited the settings.py file and added our apps to the INSTALLED_APPS setting. It looks like this:

INSTALLED_APPS = [
 'django.contrib.admin',
 'django.contrib.auth',
 'django.contrib.contenttypes',
 'django.contrib.sessions',
 'django.contrib.messages',
 'django.contrib.staticfiles',
 'authentication',
 'booking',
 'Receptionist',
 'customer',
 ]

Creating models

We open our ‘models.py’ file and start writing the models. The models.py file should look like this:

Model For Our authentication app

from django.db import modelsclass Customer(models.Model):
 username=models.CharField(max_length=100)
 password=models.CharField(max_length=100)
 email=models.CharField(max_length=50)
 profile_pic=models.ImageField(upload_to="media", height_field=None,  width_field=None, max_length=None,blank=True)
 phone_no=models.CharField(max_length=50)
 address=models.TextField()
 state=models.CharField(max_length=30,blank=True)
 pin_code=models.IntegerField(blank=True)
 def __str__(self):
 return "Customer: "+self.username
 
class RoomManager(models.Model):
 username=models.CharField(max_length=100)
 password=models.CharField(max_length=100)
 email=models.CharField(max_length=50)
 profile_pic=models.ImageField(upload_to="media", height_field=None, width_field=None, max_length=None,blank=True)
 phone_no=models.CharField(max_length=50)
 gender=models.CharField(max_length=20)
 def __str__(self): return "Room Manager: "+self.username

Model For booking app:

from django.db import models
from authentication.models import Customer,RoomManager
from datetime import date
class Contact(models.Model):
 name=models.CharField(max_length=100)
 email=models.CharField(max_length=100)
 message=models.TextField(max_length=2000)
 def __str__(self):
 return self.name
class Rooms(models.Model):
 manager=models.ForeignKey(RoomManager, on_delete=models.CASCADE)
 room_no=models.CharField(max_length=5, )
 room_type=models.CharField(max_length=50)
 is_available=models.BooleanField(default=True)
 price=models.FloatField(default=1000.00)
 no_of_days_advance=models.IntegerField()
 start_date=models.DateField(auto_now=False, auto_now_add=False)
 room_image=models.ImageField(upload_to="media", height_field=None, width_field=None, max_length=None,default='0.jpeg')
 def __str__(self):
 return "Room No: "+str(self.id)
'''
class RoomImage(models.Model):
 room=models.ForeignKey(Rooms, on_delete=models.CASCADE)
 room_image=models.ImageField(upload_to="media", height_field=None, width_field=None, max_length=None)
'''
class Booking(models.Model):
 room_no=models.ForeignKey(Rooms, on_delete=models.CASCADE)
 user_id=models.ForeignKey(Customer, on_delete=models.CASCADE)
 start_day=models.DateField(auto_now=False, auto_now_add=False)
 end_day=models.DateField(auto_now=False, auto_now_add=False)
 amount=models.FloatField()
 booked_on=models.DateTimeField(auto_now=True, auto_now_add=False)
 def __str__(self):
 return "Booking ID: "+str(self.id)
 @property
 def is_past_due(self): return date.today()>self.end_day

Model For Payment app:

from django.db import models
import secrets
from .paystack import PayStack#Create your models here.class Payment(models.Model):
 amount = models.PositiveIntegerField()
 ref = models.CharField(max_length= 200)
 email = models.EmailField()
 verified = models.BooleanField(default=False)
 date_created = models.DateTimeField(auto_now_add=True)
 
 class Meta:
 ordering = ('-date_created',)
 
 def __str__(self) -> str:
 return f"Payment: {self.amount}"
 
 def save(self, *args, **kwargs) -> None:
 while not self.ref: 
 ref = secrets.token_urlsafe(50)
 object_with_similar_ref = Payment.objects.filter(ref=ref)
 if not object_with_similar_ref:
 self.ref = ref
 super().save(*args, **kwargs)
 
 def amount_value(self) -> int:
 return self.amount * 100
 
 def verify_payment(self):
 paystack = PayStack()
 status, result = paystack.verify_payment(self.ref, self.amount)
 if status:
 if result['amount'] / 100 == self.amount:
 self.verified = True
 self.save()
 if self.verified:
 return True
 return False
 
 def __unicode__(self): return self.name

Creating and applying migrations

Now that we have a data model for our applitions, we ran the makemigrations command which notify Django that new models have been created and those changes needs to be applied to the migration. Run migrate command to do the actual migration.

python manage.py makemigrations
python manage.py migrate

Activating models

We created urls.py files for each of our apps.

urls.py For authentication app:

from django.urls import path,include
from . import views
urlpatterns=[
 path('login',views.user_login,name='user_login'),
 path('login1',views.manager_login,name='manager_login'),
 path('signup',views.user_signup,name='user_signup'),
 path('signup1',views.manager_signup,name='manager_signup'),
 path('dashboard/',include('customer.urls')),
 path('dashboard1/',include('Receptionist.urls')),
 path('add-room/',include('Receptionist.urls'))
]

urls.py For booking app:

from django.urls import path
from . import views
urlpatterns=[
 path('',views.index,name='index'),
 path('book',views.book,name='book'),
 path('contact-us',views.contact,name='contact-us'),
 path('book-now/<str:id>',views.book_now,name='book-now'),
 path('cancel-room/<str:id>',views.cancel_room,name='cancel-room'),
 path('delete-room/<str:id>',views.delete_room,name='delete-room'), # path('confirm-now-booking',views.book_confirm,name="book_confirm"),]

urls.py For customer app:

from django.urls import path
from . import views
urlpatterns=[
 path('',views.dashboard,name='user_dashboard'),
 path('details/<int:id>/<int:booking_id>',views.details,name='user_details')
]

urls.py For payment app:

from django.urls import path
from . import views
urlpatterns=[
 path('',views.dashboard,name='user_dashboard'),
 path('details/<int:id>/<int:booking_id>',views.details,name='user_details')
]

urls.py For Receptionist app:

from django.urls import path
from . import views
urlpatterns = [
 path('',views.dashboard,name="manager_dashboard"),
 path('new/',views.add_room,name="add_room"), path('update/<int:room_no>/',views.update_room,name="update_room"),]

We go to hotelsystem/urls.py and include the apps urls.
It looks like this:

from django.contrib import admin
from django.urls import path,include
from django.conf import settings
from django.conf.urls.static import static
from authentication import views
urlpatterns = [
 path('admin/', admin.site.urls),
 path('',include('booking.urls')),
 path('user/',include('authentication.urls')),
 path('manager/',include('authentication.urls')),
 path('logout',views.logout,name='logout'),
 path('api/',include('api.urls')),
 path('',include('payment.urls'))
## path('payment/', include(('payment.urls', 'payment'), namespace='payment'))
]+ static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

Setting up the admin for each model in each app

For authentication app:

from django.contrib import admin
from authentication.models import Customer, RoomManager
Contact,Rooms,Booking
## Register your models here.
admin.site.register(Customer)
admin.site.register(RoomManager)

For payment app:

from django.contrib import adminfrom .models
import Paymentadmin.site.register(Payment)

Writing urls to the views for each app

Creating templates for you views

We have created views and URL patterns for our applications. Now, it's time to add templates to display posts in a user-friendly manner.
