FULL Guide | Django messages Framework
In this Django tutorial, we have to discuss the Django messages framework in which we use different kinds of messages for different purposes. Actually, we need to display one-time notifications to the user while instructing the user. There may be different situations you have to use messages and show them to the user. Such kinds of messages we also say that flash message.
The one-time notification means you will get only a time notification message. For example, you sign up on any website. After completing your form for sign up you will be notified that you have been registered successfully.
This message will display one time. Another example, when you sign in or log in to your account, after login you redirect to the dashboard, you are welcome on the dashboard message will be for one time. When you visit the again dashboard with login you will not be notified at one time.
So such kinds of messages are called flash messages which can be used by the developer using the Django framework.
To use the messages framework, you have to enable it first in your settings.py file in the
Middleware list. Keep in mind if you have used the following middleware then you can use messages but don’t worry, this setting is done by default when you
create a Django project.‘django.contrib.sessions.middleware.SessionMiddleware’ ‘django.contrib.messages.middleware.MessageMiddleware’.
Accorindg to
Django docuemntation. We can use messages for anonymous users as well as an authenticated users also based on session and user cookie settings. To display a message, you have to need memory, but such messages store a temporary base in one request and retrieve that message for displaying to the user in a subsequent request.
Anonymous Users: Those users who are logout from their account or non-registered user.
Authenticated Users: Those users who have permission to use the limited backend area provided by the admin.
Django messages Framework Levels
There are different levels of message you can use. But it depends upon the situation and your needs. When you create a form for user registration. When you create a user registration form and the user fills in the complete providing accurate details, when a user successfully completes his/her form, then you have to use a message level ‘SUCCESS’. If the user makes any mistake then you have to use level ‘WARNING’

How to use Django message in your project
Now, you can use any level of message in your Django project depending on your needs. So, the following example will help you in using messages.
from django.shortcuts import render, redirect
from django.contrib import messages
def std_register(request):
if request.method == “POST”:
form = CreateUserForm(request.POST)
if form.is_valid():
form.save()
username = form.cleaned_data[‘username’] # Getting username from username field
messages.success(request, ‘Your account is created ‘+username) # displaying success message when propelry user is registerd. Then after dispalying message it will redirect to login page as mentioned below code of line.
return redirect(‘login’)
