Event Management System Using Python Django
Last Updated :
23 Jul, 2025
In today's fast-paced world, businesses, schools, and groups need to organize events well. An Event Management System (EMS) makes planning and managing events easier. This article will explain the structure, important parts, and how to build a helpful Event Management System with Django.
Event Management System using Django
Here, we will create the Event Management System using Django step-by-step, below is a step-by-step guide to the Event Management System using Django in Python:
Starting the Project Folder
To start the project use this command
django-admin startproject event_management_system
cd event_management_system
To start the app use this command
python manage.py startapp event_management_system_app
Now add this app to the ‘settings.py’
INSTALLED_APPS = [
"django.contrib.admin",
"django.contrib.auth",
"django.contrib.contenttypes",
"django.contrib.sessions",
"django.contrib.messages",
"django.contrib.staticfiles",
"event_management_system_app",
]
File Structure
File Structure:Note: Creating an event management system is a great way to use Django. For those looking to build more complex and dynamic systems, the Django Web Development Course provides detailed guidance.
Setting Necessary Files
models.py: This Django code defines two models, Category
and Event
. The Category
model has a name field, while the Event
model includes fields such as name, category (linked to Category model with a ForeignKey), start and end dates, priority, description, location, and organizer, each with specific data types and default values.
Python
from django.db import models
class Category(models.Model):
name = models.CharField(max_length=100)
class Event(models.Model):
name = models.CharField(max_length=100)
category = models.ForeignKey(Category, on_delete=models.CASCADE)
start_date = models.DateTimeField()
end_date = models.DateTimeField()
priority = models.IntegerField(default=1)
description = models.TextField(default='')
location = models.CharField(max_length=255, default='')
organizer = models.CharField(max_length=100, default='')
views.py: This Django code defines views for an Event Management System. It includes functions to delete events, create events with associated categories, update event details, list categories and their events, create categories, and delete categories if they don't have associated events. Additionally, there's a view for displaying a chart indicating the number of pending events for each category based on their start dates.
Python
from django.utils import timezone
from django.shortcuts import render, get_object_or_404
from django.contrib import messages
from .models import Category, Event
from django.shortcuts import render, redirect
from django.urls import reverse
def delete_event(request, event_id):
if request.method == 'POST':
event = Event.objects.get(id=event_id)
event.delete()
return redirect(reverse('category_list'))
def create_event(request):
if request.method == 'POST':
# Retrieve data from the POST request
name = request.POST.get('name')
category_id = request.POST.get('category')
start_date = request.POST.get('start_date')
end_date = request.POST.get('end_date')
priority = request.POST.get('priority')
description = request.POST.get('description')
location = request.POST.get('location')
organizer = request.POST.get('organizer')
# Retrieve the Category object
category = Category.objects.get(pk=category_id)
# Create the Event object
event = Event.objects.create(
name=name,
category=category,
start_date=start_date,
end_date=end_date,
priority=priority,
description=description,
location=location,
organizer=organizer
)
# Redirect to the event list page
return redirect('category_list')
else:
categories = Category.objects.all()
return render(request, 'event_management_system_app/create_event.html', {'categories': categories})
def update_event(request, event_id):
event = Event.objects.get(pk=event_id)
if request.method == 'POST':
# Update event fields based on form data
event.name = request.POST.get('name')
event.start_date = request.POST.get('start_date')
event.end_date = request.POST.get('end_date')
event.priority = request.POST.get('priority')
event.description = request.POST.get('description')
event.location = request.POST.get('location')
event.organizer = request.POST.get('organizer')
event.save()
return redirect('category_list')
else:
# Render update event page with event data
return render(request, 'event_management_system_app/update_event.html', {'event': event})
def category_list(request):
categories = Category.objects.all()
return render(request, 'event_management_system_app/category_list.html', {'categories': categories})
def create_category(request):
if request.method == 'POST':
name = request.POST.get('name')
Category.objects.create(name=name)
return redirect('category_list')
return render(request, 'event_management_system_app/create_category.html')
def delete_category(request, category_id):
category = Category.objects.get(pk=category_id)
if category.event_set.exists():
messages.error(
request, "You cannot delete this category as it contains events.")
else:
category.delete()
messages.success(request, "Category deleted successfully.")
return redirect('category_list')
def category_events(request, category_id):
category = get_object_or_404(Category, pk=category_id)
events = category.event_set.all()
return render(request, 'event_management_system_app/category_events.html', {'category': category, 'events': events})
def event_chart(request):
categories = Category.objects.all()
pending_counts = {}
for category in categories:
pending_counts[category.name] = Event.objects.filter(
category=category,
start_date__gt=timezone.now()
).count()
return render(request, 'event_management_system_app/event_chart.html', {'pending_counts': pending_counts})
urls.py: This Django urlpatterns
configuration maps URLs to corresponding views in an Event Management System. The patterns include paths for listing categories, creating categories, viewing category events, deleting categories, creating events, updating events, deleting events, and displaying an event chart
Python
from django.contrib import admin
from django.urls import path
from event_management_system_app import views
urlpatterns = [
path('admin/', admin.site.urls),
path('', views.category_list, name='category_list'),
path('categories/create/', views.create_category, name='create_category'),
path('categories/<int:category_id>/', views.category_events, name='category_events'),
path('categories/delete/<int:category_id>/', views.delete_category, name='delete_category'),
path('events/create/', views.create_event, name='create_event'),
path('events/update/<int:event_id>/', views.update_event, name='update_event'),
path('events/delete/<int:event_id>/', views.delete_event, name='delete_event'),
path('event-chart/', views.event_chart, name='event_chart'),
]
Creating GUI
category_events.html: This HTML file utilizes Bootstrap for a clean Event Management System interface, featuring buttons for adding events and navigating categories. It incorporates JavaScript to dynamically sort events by priority and display countdown timers for upcoming events in real-time. The modal design allows users to view detailed information about each event.

event_chart.html: his HTML file uses Bootstrap and Chart.js to create a "Pending Events by Category" chart. It visualizes the count of pending events in each category. The Chart.js library is employed to generate a bar chart with colorful bars representing different categories and their corresponding pending event counts.
