Django cheatsheet - Views

View are something that accepts a request, and returns some kind of a response.

In the render() function, you can pass a context that are variables you can pass to your template.

how to add a new view

define the URL in your-project/your-app/urls.py
add a view in your-projects/your-app/views/new-view.py
import the view in your-projects/your-app/views/__init__.py

shortcuts: render, redirect

from django.shortcuts import render, redirectdef index(request):  students = Students.objects.all()  context = { "students": students }  return render("index.html", context)

messages

https://docs.djangoproject.com/en/4.1/ref/contrib/messages/#using-messages-in-views-and-templates

If you want to use "messages" (e.g. flash messages, toast messages in other frameworks), you can use the messages framework.

Add this import,

from django.contrib import messages

... and call the messages like this in your views.

messages.debug(request, '%s SQL statements were executed.' % count)messages.info(request, 'Three credits remain in your account.')messages.success(request, 'Profile details updated.')messages.warning(request, 'Your account expires in three days.')messages.error(request, 'Document deleted.')

The template can show the messages like this:

{% if messages %}<ul class="messages">    {% for message in messages %}    <li>{{ message }}</li>    {% endfor %}</ul>{% endif %}

It' s important to iterate all the messages, otherwise the messages will not be cleared.

from django.contrib import messages# view to create new studentdef new(request):  if request.method == "POST":    # do something with the form     student.save()    # send messages    messages.success(request, "saved student")
