Python | ToDo webapp using Django

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
