Prerequisite : django installation
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 created to understand the basics of Django. In this web app, one can create notes like Google Keep or Evernote.
Modules required :
- django : install django
- crispy_forms :
pip install --upgrade django-crispy-forms
basic setup :
Start a project by the following command –
django-admin startproject todo-site
Change directory to todo-site –
cd todo-site
Start the server- Start the server by typing following command in terminal –
python manage.py runserver
To check whether the server is running or not go to a web browser and enter http://127.0.0.1:8000/
as URL.
Now stop the server by pressing
ctrl-c
Let’s create an app now.
python manage.py startapp todo
Goto todo/ folder by doing : cd todo
and create a folder with index.html
file : templates/todo/index.html
Open the project folder using a text editor. The directory structure should look like this :
Now add todo app and crispty_form
in your todo_site
in settings.py
.
Edit urls.py
file in todo_site
:
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 ############ path( 'del/' , views.remove, name = "del" ), ######################################################################## path( 'admin/' , admin.site.urls), ] |
Edit models.py
in todo :
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< / pre> |
Edit views.py
in todo :
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 recive todo item id from url ## def remove(request, item_id): item = Todo.objects.get( id = item_id) item.delete() messages.info(request, "item removed !!!" ) return redirect( 'todo' ) |
Now create a forms.py
in todo :
from django import forms from .models import Todo class TodoForm(forms.ModelForm): class Meta: model = Todo fields = "__all__" < / pre> |
Register models to admin :
Navigate to templates/todo/index.html
and edit it : link to index.html file
Make migrations and migrate it
python manage.py makemigrations python manage.py migrate
Now you can run the server to see your todo app
python manage.py runserver
