To create a todo app with Django, you’ll need to follow these steps:

Install Django and create a new project:

pip install django
django-admin startproject todo

Create a new app within the project:

python manage.py startapp tasks

Define the model for the to-do tasks in tasks/models.py A to-do task might have a title, description, and completion status. You can use the following code as a starting point:

from django.db import models

class Task(models.Model):
     title = models.CharField(max_length=200)
     description = models.TextField()
     completed = models.BooleanField(default=False)

    def __str__(self):
       return self.title

Run the database migrations to create the database table for the tasks:

python manage.py makemigrations
python manage.py migrate

Create a view function in tasks/views.py to display a list of tasks and a form to add new tasks. You can use the following code as a starting point:

from django.shortcuts import render
from .models import Task
from .forms import TaskForm

def task_list(request):
    tasks = Task.objects.all()
    form = TaskForm()
    if request.method == 'POST':
       form = TaskForm(request.POST)
       if form.is_valid():
          form.save()
          return redirect('/')
    context = {'tasks': tasks, 'form': form}
    return render(request, 'tasks/task_list.html', context)

Create a template for the task list view in tasks/templates/tasks/task_list.html. You can use the following code as a starting point:

<h1>Todo List</h1>

<form method="POST" action="{% url 'task_list' %}">
{% csrf_token %}
{{ form.as_p }}
<input type="submit" value="Add Task">
</form>

<ul>
{% for task in tasks %}
<li>{{ task }}</li>
{% endfor %}
</ul>

 

Create a form for the add task form in tasks/forms.py. You can use the following code as a starting point:

from django import forms
from .models import Task

class TaskForm(forms.ModelForm):
     class Meta:
           model = Task
           fields = ['title', 'description']

Create a URL pattern for the task list view in tasks/urls.py:

from django.urls import path
from . import views

urlpatterns = [
path('', views.task_list, name='task_list'),
]

Include the URL patterns of the tasks app in the main urls.py file:

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

urlpatterns = [
path('tasks/', include('tasks.urls')),
path('admin/', admin.site.urls),
]

Run the development server to test the todo app:

python manage.py runserver
