Django is a high-level Python Web framework-based web framework that allows rapid development and clean, pragmatic design. today we will create a todo app to understand the basics of Django. In this web app, one can create notes like Google Keep or Evernote.
Basic setup
Create a virtual environment, and install the packages:
pip install django-crispy-forms
pip install Django
Step 1: Start a project with the following command
django-admin startproject todo_site
Step 2: Change the directory to todo_site.
cd todo_site
Let’s create an app now
Step 3: Create an app with the following command.
python manage.py startapp todo
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 admin
from django.urls import path
from todo import views
urlpatterns = [
#####################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 models
from django.utils import timezone
class 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, redirect
from django.contrib import messages
# import todo form and models
from .forms import TodoForm
from .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 forms
from .models import Todo
class TodoForm(forms.ModelForm):
class Meta:
model = Todo
fields = "__all__"
Step 9: Register models to admin
Step 10: Create templates/todo/index.html
