Django is a very robust full-stack web framework. It uses Python on the server side and provides API to integrate with almost any front-end web frameworks like React, Next, Vue, and Angular. In Django developers use MVT(Model View Template) architecture to build an application. In this project on Task Management Systems using Django, we are going to stick with built-in Django templates that use the Django Template Language. This project is a complete demonstration of Task Management Systems where the user can create their account and log in to the application. In the tasks section user can create a task with the rich text editor. From the home page, the user is capable of viewing, editing, and deletion a particular task.

Project Overview

Technologies and Skills Required to Implement this project

  1. Python

  2. Django web framework

  3. SQLite

  4. Bootstrap

  5. HTML, CSS, and JavaScript

Building Django task management system

This project will have limited functionalities of a regular task management system software or application. The user can create an account and log in to the application with proper form validation of each field. After login, the user will be automatically redirected to the home or all tasks section of the application containing four columns To Do, Started, Complete, and Archive. Initially, tasks will be empty and the user can add new tasks with the task details. The project also includes a strict authentication system as all the routes are protected thus unauthorized users can not access any page and will be automatically been redirected to the login page.

ER Diagram for Django Task Management System

User interface use cases

  1. The user creates a new account

  2. User login to an extent account

  3. Add new task

  4. Update existing task

  5. View task details

  6. Delete task

  7. Rich Text Editor support for user

Admin interface use cases

  1. Create new account

  2. Login as administrator

  3. Admin can perform CRUD operation on all the data

  4. Manage user details

  5. Manage user permissions

System requirements

  1. The system must have an updated version of Python and PIP installed. Here we are using Python 3.11.7 and PIP 23.3.2.

  2. One pip package we need to run this project smoothly is virtualenv 20.25.0.

  3. We are using VS Code Editor but it's not the only one but rather the preferred one.

Steps to implement this project

  • Create a new directory named django_task_management_system.

  • Open any terminal in the directory django_task_management_system and run this command python -m venv venv to create a new virtual environment specifically for this project. We can also run the application without this step but it's not recommended to do so as per the Django Official Documentation.

  • Now run "code ." to open the directory in VS Code. Till now if everything is executed properly then the output must be like this.

project-set-up

Opening VS Code from terminal

  • To activate the virtual environment run venv/Scripts/activate, this step might ask for some permission, or the operating system might find it a threat but we have to allow it.

activated-venv

Terminal after activating venv.

  • Execute pip install django, django-ckeditor, this command will install Django and ckeditor in the project environment.

  • Run django-admin startproject django_task_management_system, it will create a new Django application in the working directory of the terminal.

folder-structure-before

Folder structure after creating the project.

  • Move the manage.py file and the django_task_management_system directory to the parent directory and the folder structure should be like in the image.

folder-structure-after

Folder structure after moving the directory.

  • Execute python manage.py startapp base in the terminal, it will create an app with the name base.

final-folder-structure

Folder structure after creating the base app.

  • Run python manage.py runserver, this will start a local server at localhost:8000 and will display a Django start page like this. Some errors might occur in the terminal but those are nothing to worry about.

base-app-started

The Django server running with some errors in the terminal.

django-success-page

Django installation success page.

  • Turn off the running local server by pressing ctrl + c and let's start creating the application.

  • Open the settings.py file in the django_task_management_system directory and replace the default code with this code.

  • Create a directory in the templates directory with the name base. Now create files with the names login.html, register.html, task_create.html, task_delete.html, task_detail.html, task_list.html, and task_update.html. After creating all the files the base directory folder structure should be like this.
