Let’s create an app now
Step 3: Create an app with the following command.

The directory structure should look like this:
Step 4: Now add the todo app in your todo_site in settings.py
Step 5: Edit urls.py file in todo_site
Python3
from django.contrib import adminfrom django.urls import pathfrom todo import viewsurlpatterns = [ #####################home_page########################################### path('', views.index, name="todo"), ####################give id no. item_id name or item_id=i.id ############ # pass item_id as primary key to remove that the todo with given id path('del/<str:item_id>', views.remove, name="del"), ######################################################################## path('admin/', admin.site.urls),] |
Step 6: Edit models.py in todo
Python3
from django.db import modelsfrom django.utils import timezoneclass Todo(models.Model): title = models.CharField(max_length=100) details = models.TextField() date = models.DateTimeField(default=timezone.now) def __str__(self): return self.title |
Step 7: Edit views.py in todo
Python3
from django.shortcuts import render, redirectfrom django.contrib import messages# import todo form and modelsfrom .forms import TodoFormfrom .models import Todo###############################################def index(request): item_list = Todo.objects.order_by("-date") if request.method == "POST": form = TodoForm(request.POST) if form.is_valid(): form.save() return redirect('todo') form = TodoForm() page = { "forms": form, "list": item_list, "title": "TODO LIST", } return render(request, 'todo/index.html', page)### function to remove item, it receive todo item_id as primary key from url ##def remove(request, item_id): item = Todo.objects.get(id=item_id) item.delete() messages.info(request, "item removed !!!") return redirect('todo') |
Step 8: Now create a forms.py in todo
Python3
from django import formsfrom .models import Todoclass TodoForm(forms.ModelForm): class Meta: model = Todo fields = "__all__" |
Step 9: Register models to admin
Step 10: Create templates/todo/index.html
HTML
