Hello there, future web developers and productivity enthusiasts! Are you looking for a fun and practical way to dive into web development? Or perhaps you’re just tired of losing track of your daily tasks and want a personalized solution? You’re in the right place!

Today, we’re going to embark on an exciting journey: building your very own Productivity Tracker using Django. Django is a powerful and popular web framework for Python, known for its “batteries-included” approach, meaning it comes with many features built-in so you don’t have to create everything from scratch. It’s a fantastic tool for beginners because it helps you build robust web applications relatively quickly.

By the end of this guide, you’ll have a basic web application that can help you keep tabs on your tasks, and you’ll have a much better understanding of how web applications work. Let’s get started!

What is a Productivity Tracker?

Before we jump into coding, let’s clarify what we’re building. A productivity tracker is essentially a tool that helps you:

• List your tasks: Keep all your to-dos in one organized place.
• Track progress: See which tasks you’ve started or completed.
• Stay organized: Manage your workload more effectively.

Imagine a simple to-do list, but on a webpage that you can access from anywhere. That’s our goal!

Why Django for This Project?

You might wonder, “Why Django?” Here are a few excellent reasons, especially for beginners:

• Python-based: If you’ve learned Python (a very beginner-friendly programming language), Django uses it extensively.
• Batteries Included: Django comes with many features ready to use, like an administrative interface (a ready-made control panel for your data), database connectivity, and an authentication system (for user logins). This means less time setting up basic functionality and more time building your unique features.
• Structured Approach: Django encourages good design patterns, specifically the MVT (Model-View-Template) pattern.
  • Model: How your data is structured and stored (e.g., what information a “task” should have).
  • View: The logic that processes user requests and fetches data (e.g., when you ask to see all tasks).
  • Template: How the information is displayed to the user (e.g., the HTML page showing your tasks).
    This structure helps keep your code organized and easier to manage as your project grows.
• Large Community: Django has a huge and active community, which means tons of resources, tutorials, and help available if you get stuck.

Setting Up Your Development Environment

Before we write any Django code, we need to set up our computer.

1. Install Python

Django is built with Python, so you’ll need it installed first.
* Go to the official Python website: python.org
* Download and install the latest stable version of Python 3. Make sure to check the box that says “Add Python to PATH” during installation if you’re on Windows.

2. Create a Virtual Environment

A virtual environment is a segregated space on your computer where you can install specific versions of Python packages for a particular project without affecting other projects. It’s like having a separate toolbox for each project. This is a best practice in Python development.

Open your terminal or command prompt and navigate to where you want to store your project (e.g., cd Documents/CodingProjects). Then run these commands:

python -m venv my_productivity_env

This command creates a new folder named my_productivity_env which will hold our virtual environment.

Now, you need to “activate” this environment:

• On Windows:
  bash
.\my_productivity_env\Scripts\activate
• On macOS/Linux:
  bash
source my_productivity_env/bin/activate
  You’ll know it’s active when you see (my_productivity_env) at the beginning of your terminal prompt.

3. Install Django

With your virtual environment activated, we can now install Django.

pip install django

pip is Python’s package installer, used to install libraries and frameworks like Django.

Starting Your Django Project

Now that Django is installed, let’s create our very first project!

django-admin startproject productivity_tracker .

• django-admin is a command-line utility for administrative tasks.
• startproject tells Django to create a new project.
• productivity_tracker is the name of our project.
• The . (dot) at the end tells Django to create the project files in the current directory, rather than creating an extra nested folder.

If you list the files in your directory (ls on macOS/Linux, dir on Windows), you’ll see a manage.py file and a folder named productivity_tracker.

• manage.py: This is another command-line utility for our specific project. We’ll use it a lot!
• productivity_tracker/ (inner folder): This folder contains your project’s main settings and URL configurations.

Creating Your First Django App

In Django, projects are made up of “apps.” An app is a self-contained module that does one specific thing (e.g., a “tasks” app, a “users” app). This helps keep your code organized and reusable. Let’s create an app for our tasks.

Make sure you are in the same directory as manage.py, then run:

python manage.py startapp tasks

This creates a new folder called tasks inside your project.

Registering Your App

Django needs to know about this new app. Open the productivity_tracker/settings.py file (the one inside the productivity_tracker folder, not the project root) and find the INSTALLED_APPS list. Add 'tasks' to it:

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'tasks', # <--- Add this line
]

Defining Your Data Model

The Model defines the structure of your data. For our productivity tracker, we’ll need a “Task” model. Each task will have a title, a description, a creation date, and whether it’s completed.

Open tasks/models.py and modify it like this:

from django.db import models # This line is usually already there

class Task(models.Model):
    title = models.CharField(max_length=200) # A short text field for the task name
    description = models.TextField(blank=True, null=True) # A long text field, optional
    created_at = models.DateTimeField(auto_now_add=True) # Automatically sets creation timestamp
    is_complete = models.BooleanField(default=False) # A true/false field, default to not complete

    def __str__(self):
        return self.title # This makes it easier to read Task objects in the admin

• models.Model is the base class for all Django models.
• CharField, TextField, DateTimeField, BooleanField are different types of fields Django provides to store various kinds of data.

Making Migrations

After defining our model, we need to tell Django to create the corresponding table in our database. We do this using migrations. Migrations are Django’s way of managing changes to your database schema (the structure of your data).

Run these commands in your terminal:

python manage.py makemigrations tasks
python manage.py migrate

• makemigrations tasks: This command creates a new migration file inside your tasks/migrations folder, which is like a set of instructions for changing your database based on your models.py file.
• migrate: This command applies those instructions (and any other pending migrations from Django’s built-in apps) to your database.

Creating the Admin Interface

Django comes with a fantastic built-in administration panel. Let’s make our Task model available there so we can easily add, view, and edit tasks.

Open tasks/admin.py and add the following:

from django.contrib import admin
from .models import Task # Import our Task model

admin.site.register(Task) # Register the Task model with the admin site

Creating an Administrator User

To access the admin panel, you need an administrator (superuser) account.

python manage.py createsuperuser

Follow the prompts to create a username, email, and password.

Running the Development Server

Now, let’s see our project in action!

python manage.py runserver

Open your web browser and go to http://127.0.0.1:8000/admin/. Log in with the superuser credentials you just created. You should see “Tasks” listed there. Click on it, and you can now add new tasks!

Basic Views and URLs

While the admin panel is great for managing data, we want our users to see their tasks on a custom webpage. This is where Views and URLs come in.

• View: A Python function or class that receives a web request and returns a web response (like an HTML page).
• URL: A web address that maps to a specific view.

Creating a View

Open tasks/views.py and add a simple view to display all tasks:

from django.shortcuts import render # Used to render HTML templates
from .models import Task # Import our Task model

def task_list(request):
    tasks = Task.objects.all().order_by('-created_at') # Get all tasks, ordered by creation date
    return render(request, 'tasks/task_list.html', {'tasks': tasks})

• Task.objects.all() retrieves all Task objects from the database.
• render() takes the request, the template name, and a dictionary of data to send to the template.

Defining URLs for the App

Now we need to create a urls.py file inside our tasks app to define the URL patterns specific to this app. Create a new file named tasks/urls.py and add:

from django.urls import path
from . import views # Import the views from the current app

urlpatterns = [
    path('', views.task_list, name='task_list'), # Defines the root URL for the app
]

• path('', ...) means that when someone visits the base URL for this app (e.g., /tasks/), it should call the task_list view.
• name='task_list' gives this URL a name, which is useful for referencing it elsewhere in your project.

Connecting App URLs to Project URLs

Finally, we need to tell the main project (in productivity_tracker/urls.py) to include the URLs from our tasks app.

Open productivity_tracker/urls.py and modify it:

from django.contrib import admin
from django.urls import path, include # Import 'include'

urlpatterns = [
    path('admin/', admin.site.urls),
    path('tasks/', include('tasks.urls')), # Include URLs from our 'tasks' app
]

• path('tasks/', include('tasks.urls')) means that any URL starting with /tasks/ will be handled by the URL patterns defined in tasks/urls.py. So, if you go to http://127.0.0.1:8000/tasks/, it will look for a matching pattern in tasks/urls.py.

Creating a Simple Template

Our task_list view currently tries to render a template named tasks/task_list.html. We need to create this file.

First, create a templates folder inside your tasks app folder:
tasks/templates/tasks/task_list.html

The nested tasks folder inside templates is a Django convention to prevent template name clashes if you have multiple apps with similarly named templates.

Now, open tasks/templates/tasks/task_list.html and add some basic HTML:

<!-- tasks/templates/tasks/task_list.html -->

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">

        ul { list-style: none; padding: 0; }
        li { background-color: #e9e9e9; margin-bottom: 10px; padding: 10px 15px; border-radius: 5px; display: flex; justify-content: space-between; align-items: center; }

    <div class="container">

        {% if tasks %}
            <ul>
                {% for task in tasks %}
                    <li class="{% if task.is_complete %}completed{% endif %}">
                        <div>
                            <strong>{{ task.title }}</strong>
                            {% if task.description %}
                                <p>{{ task.description }}</p>

                            {% else %}
                                <span>&#9744; Pending</span>
                            {% endif %}
                        </div>
                    </li>
                {% endfor %}
            </ul>
        {% else %}
            <p>No tasks yet. Go to <a href="/admin/tasks/task/add/">admin</a> to add some!</p>
        {% endif %}
    </div>
</body>
</html>

• {% if tasks %} and {% for task in tasks %} are Django template tags for control flow (like if-else statements and loops in Python).
• {{ task.title }} is a Django template variable that displays the title attribute of a task object.
• |date:"M d, Y H:i" is a template filter that formats the created_at timestamp.

Seeing Your Tracker!

With the development server still running (python manage.py runserver), open your browser and navigate to http://127.0.0.1:8000/tasks/.

You should now see your list of tasks! If you’ve added tasks through the admin panel, they will appear here. You can try adding more tasks in the admin and refreshing this page to see the updates.

Next Steps and Further Enhancements

Congratulations! You’ve successfully built a basic productivity tracker with Django. This is just the beginning. Here are some ideas for how you can expand and improve your project:

• Add a Form: Create a web form to add new tasks directly from the /tasks/ page, without needing to go to the admin.
• Mark as Complete: Add buttons or checkboxes to mark tasks as complete or incomplete from the list page.
• Edit/Delete Tasks: Implement functionality to edit or delete existing tasks.
• User Authentication: Allow different users to have their own task lists. Django has a robust built-in authentication system for this!
• Styling: Make your application look even better with more advanced CSS frameworks like Bootstrap or Tailwind CSS.
• Deployment: Learn how to deploy your Django application to a live server so others can use it.

Conclusion

Building a productivity tracker is a fantastic way to learn the fundamentals of web development with Django. You’ve touched upon creating models, working with databases through migrations, setting up an admin interface, and handling user requests with views and templates. Django’s structure and “batteries-included” philosophy make it an excellent choice for turning your ideas into functional web applications.

Keep experimenting, keep learning, and happy coding!

Hello there, aspiring web developer! Ever wanted to build your own website or web application but felt overwhelmed by where to start? You’re in luck! Today, we’re going to take a fun and practical first step together: creating a simple To-Do List application using a powerful web framework called Django.

A To-Do List app is a fantastic project for beginners because it covers many fundamental concepts without being too complicated. By the end of this guide, you’ll have a basic application running that can display a list of tasks – a solid foundation for more complex projects!

What is Django?

Let’s start with the star of our show: Django.

Imagine you want to build a house. You could gather every single brick, piece of wood, and nail yourself, and design everything from scratch. Or, you could use a pre-built kit that provides you with walls, roofs, and windows, letting you focus on the interior design and unique touches.

Django is like that pre-built kit for websites. It’s a web framework (a toolkit of pre-written code) that helps you build robust and scalable web applications quickly, without having to reinvent the wheel for common web development tasks. It’s written in Python, a very beginner-friendly programming language.

Getting Started: Setting Up Your Environment

Before we dive into coding, we need to set up our workspace. Think of it as preparing your construction site!

Prerequisites

You’ll need a few things installed on your computer:

• Python: Make sure you have Python 3 installed. You can download it from the official Python website.
• pip: This is Python’s package installer, usually comes with Python. We’ll use it to install Django.
• A Text Editor: Visual Studio Code, Sublime Text, Atom, or even a simple Notepad++ will work!

Creating a Virtual Environment

It’s good practice to create a virtual environment for each of your Python projects. This keeps the packages (like Django) for one project separate from others, preventing conflicts.

1. Create a project folder:
   bash
mkdir my_todo_project
cd my_todo_project
2. Create the virtual environment:
   bash
python -m venv venv
   Explanation: python -m venv venv tells Python to create a new virtual environment named venv inside your project folder.
3. Activate the virtual environment:
   • On Windows:
     bash
.\venv\Scripts\activate
   • On macOS/Linux:
     bash
source venv/bin/activate
     You’ll see (venv) appear at the start of your command prompt, indicating that your virtual environment is active.
4. Install Django: Now, with your virtual environment active, install Django using pip.
   bash
pip install django

Starting Your Django Project

With Django installed, let’s create our first Django project.

1. Start a new project:
   bash
django-admin startproject todo_project .
   Explanation:

   • django-admin is the command-line tool Django provides.
   • startproject is the command to create a new project.
   • todo_project is the name of our main project.
   • . (the dot) tells Django to create the project files in the current directory, instead of creating another nested folder.

   After this, you’ll see a structure like this:
   my_todo_project/
├── venv/
├── todo_project/
│ ├── __init__.py
│ ├── settings.py # Project settings
│ ├── urls.py # Project URL definitions
│ └── wsgi.py
├── manage.py # A utility script to interact with your project
   2. Run the development server: Let’s make sure everything is set up correctly.
   bash
python manage.py runserver
   You should see output similar to:
   “`
   Watching for file changes with StatReloader
   Performing system checks…

   System check identified no issues (0 silenced).

   You have 18 unapplied migration(s). Your project may not work properly until you apply the migrations for app(s): admin, auth, contenttypes, sessions.
   Run ‘python manage.py migrate’ to apply them.
   September 10, 2023 – 10:00:00
   Django version 4.2.5, using settings ‘todo_project.settings’
   Starting development server at http://127.0.0.1:8000/
   Quit the server with CONTROL-C.
   ``
Open your web browser and go tohttp://127.0.0.1:8000/. You should see a "The install worked successfully! Congratulations!" page. This means your Django project is up and running! PressCTRL+C` in your terminal to stop the server for now.

Creating a Django App

In Django, projects are made of smaller, reusable components called apps. Think of the todo_project as the entire house, and an app as a specific room (like the kitchen or bedroom) that has a specific purpose. We’ll create an app specifically for our To-Do list functionality.

1. Create a new app:
   bash
python manage.py startapp todo
   This creates a new folder named todo inside my_todo_project/ with its own set of files.

2. Register your app: Django needs to know about your new todo app. Open todo_project/settings.py and add 'todo' to the INSTALLED_APPS list.

   “`python

   todo_project/settings.py

   INSTALLED_APPS = [
   ‘django.contrib.admin’,
   ‘django.contrib.auth’,
   ‘django.contrib.contenttypes’,
   ‘django.contrib.sessions’,
   ‘django.contrib.messages’,
   ‘django.contrib.staticfiles’,
   ‘todo’, # <— Add your app here
   ]
   “`

Defining Your To-Do Model

Now, let’s define what a “task” in our To-Do list should look like. In Django, we do this using models. A model is like a blueprint for the data you want to store in your database. Django’s models also provide an easy way to interact with your database without writing complex SQL code (this is called an ORM – Object-Relational Mapper).

1. Open todo/models.py and define your Task model:

   “`python

   todo/models.py

   from django.db import models

   class Task(models.Model):
   title = models.CharField(max_length=200) # A short text for the task name
   description = models.TextField(blank=True, null=True) # Longer text, optional
   created_at = models.DateTimeField(auto_now_add=True) # Date and time created, set automatically
   completed = models.BooleanField(default=False) # True if task is done, False otherwise

   def __str__(self):
       return self.title # How a Task object will be displayed (e.g., in the admin)
   

   ``
*Explanation:*
*models.Modelmeans ourTaskclass inherits all the good stuff from Django's model system.
*title: ACharField(character field) for short text, with a maximum length.
*description: ATextFieldfor longer text.blank=Truemeans it's not required to fill this field in forms, andnull=Trueallows the database field to be empty.
*created_at: ADateTimeFieldthat automatically sets the current date and time when a task is created (auto_now_add=True).
*completed: ABooleanField(true/false) with a default value ofFalse.
*str(self)`: This special method defines how an object of this model will be represented as a string. It’s helpful for displaying objects in the admin panel.

2. Make migrations: After defining your model, you need to tell Django to create the necessary tables in your database.
   bash
python manage.py makemigrations
   This command creates migration files that describe the changes to your database schema. You’ll see something like Migrations for 'todo': 0001_initial.py.

3. Apply migrations: Now, apply those changes to your actual database.
   bash
python manage.py migrate
   This command executes the migration files, creating the Task table (and other default Django tables) in your database.

Making It Visible: The Admin Panel

Django comes with a powerful, ready-to-use admin panel. It’s a web interface that allows you to manage your data easily. Let’s make our Task model accessible through it.

1. Create a superuser: This is an administrator account for your Django project.
   bash
python manage.py createsuperuser
   Follow the prompts to create a username, email (optional), and password.

2. Register your model: Open todo/admin.py and register your Task model:
   “`python
   # todo/admin.py

   from django.contrib import admin
   from .models import Task

   admin.site.register(Task)
   “`

3. Run the server again:
   bash
python manage.py runserver
   Go to http://127.0.0.1:8000/admin/ in your browser. Log in with the superuser credentials you just created. You should now see “Tasks” under the “TODO” section. Click on “Tasks” to add a new task, view, or edit existing ones! This is a great way to quickly add some sample data.

Basic Views and URLs

Now that we can store tasks, let’s display them to users! This involves two main components: views and URLs.

• A view is a Python function (or class) that takes a web request and returns a web response. It’s like the “brain” that decides what data to get from the model and what to show on the webpage.

• A URL (Uniform Resource Locator) is the web address that users type into their browser. We need to tell Django which view should handle which URL.

• Create a view: Open todo/views.py and add a function to display tasks:
  “`python
  # todo/views.py

  from django.shortcuts import render
  from .models import Task # Import our Task model

  def task_list(request):
  tasks = Task.objects.all().order_by(‘-created_at’) # Get all tasks, newest first
  return render(request, ‘todo/task_list.html’, {‘tasks’: tasks})
  ``
*Explanation:*
*task_list(request): This is our view function. It takes arequestobject as an argument.
*tasks = Task.objects.all().order_by(‘-created_at’): This line uses ourTaskmodel to fetch all tasks from the database and orders them by their creation date, with the newest first (the–sign means descending order).
*render(request, ‘todo/task_list.html’, {‘tasks’: tasks}): This is a shortcut function that combines a request, a **template** (an HTML file), and a dictionary of data ({‘tasks’: tasks}) into an HTTP response. It means "render thetask_list.htmlfile, and make thetasks` variable available inside it.”

• Define URLs for the app: Create a new file inside your todo app folder named urls.py.

  “`python

  todo/urls.py

  from django.urls import path
  from . import views # Import our views from the current app

  urlpatterns = [
  path(”, views.task_list, name=’task_list’), # Our root URL for the app
  ]
  ``
*Explanation:*
*path(”, views.task_list, name=’task_list’): This maps the empty path (meaninghttp://127.0.0.1:8000/todo/if we set it up that way) to ourtask_listview.name=’task_list’` gives this URL a memorable name for later use.

• Include app URLs in the project’s URLs: We need to tell the main todo_project about the URLs defined in our todo app. Open todo_project/urls.py.

  “`python

  todo_project/urls.py

  from django.contrib import admin
  from django.urls import path, include # Import include

  urlpatterns = [
  path(‘admin/’, admin.site.urls),
  path(‘todo/’, include(‘todo.urls’)), # <— Add this line
  ]
  ``
*Explanation:*
*path(‘todo/’, include(‘todo.urls’)): This tells Django that any URL starting withtodo/should be handed over to the URL patterns defined in ourtodoapp'surls.py. So, if you go tohttp://127.0.0.1:8000/todo/, it will use thetask_list` view we defined.

Creating a Simple Template

Finally, let’s create the HTML file that our task_list view will render to display the tasks. Django uses templates to separate Python code logic from the presentation (HTML).

1. Create a templates directory: Inside your todo app folder, create a new folder named templates. Inside templates, create another folder named todo. This structure (app_name/templates/app_name/) is a best practice to avoid conflicts if you have multiple apps with similarly named templates.
   my_todo_project/
├── ...
├── todo/
│ ├── migrations/
│ ├── templates/
│ │ └── todo/ # <--- New folder
│ │ └── task_list.html # <--- New file
│ ├── __init__.py
│ ├── admin.py
│ ├── apps.py
│ ├── models.py
│ ├── tests.py
│ ├── urls.py # <--- New file
│ └── views.py
├── ...

2. Create task_list.html: Open todo/templates/todo/task_list.html and add this HTML:
   “`html
   

   <!DOCTYPE html>
   
   
   
   
   

   
   

   My To-Do List

   {% if tasks %} {# Check if there are any tasks #}
       <ul>
           {% for task in tasks %} {# Loop through each task #}
               <li class="{% if task.completed %}completed{% endif %}">
                   <h2>{{ task.title }}</h2>
                   {% if task.description %}
                       <p class="description">{{ task.description }}</p>
                   {% endif %}
                   <small>Created: {{ task.created_at|date:"M d, Y" }}</small><br>
                   <small>Status: {% if task.completed %}Completed{% else %}Pending{% endif %}</small>
               </li>
           {% endfor %}
       </ul>
   {% else %} {# If no tasks #}
       <p>No tasks yet! Time to add some in the admin panel.</p>
   {% endif %}

*Explanation:*
*{% if tasks %}and{% for task in tasks %}: These are Django's **template tags**. They allow you to add basic logic (likeifstatements andforloops) directly into your HTML.
*{{ task.title }}: This is a **template variable**. It displays the value of thetitleattribute of thetaskobject passed from the view.
*{{ task.created_at|date:”M d, Y” }}: This uses a **template filter** (|date:”M d, Y”`) to format the date nicely.

Seeing Your To-Do List in Action!

1. Run the server again (if it’s not already running):
   bash
python manage.py runserver
2. Open your browser and navigate to http://127.0.0.1:8000/todo/.

You should now see your very own To-Do List, displaying any tasks you added through the admin panel! How cool is that?

Conclusion

Congratulations! You’ve just taken a significant step into the world of web development with Django. In this guide, you’ve learned to:

• Set up a Django project and app.
• Define a data model (Task).
• Manage your data using the Django admin panel.
• Create a view to fetch data.
• Map URLs to your views.
• Display data using Django templates.

This is just the beginning! From here, you can expand this application by adding features like:
* Forms to add new tasks directly from the main page.
* Buttons to mark tasks as completed.
* User authentication so different users have their own To-Do lists.

Keep exploring, keep building, and have fun on your coding journey!
