Question

I would like to know how to display the greeting message “Welcome User, You are logged in” once the user login and it should vanish within 5 seconds.

The message will be displayed once after the user’s successful login but not again on the consecutive visit of the home page during the same session. Because I have taken username in session in the home.html.

Answer 1

Use django’s messaging framework and wrap the login view:

from django.contrib import messages
from django.contrib.auth.views import login

def custom_login(request,*args, **kwargs):
    response = login(request, *args, **kwargs):
    if request.user.is_authenticated():
         messages.info(request, "Welcome ...")
    return response

and in your template somewhere:

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

along with some jquery to hide any message after 5 seconds:

$(document).ready(function(){
    $('.messages').delay(5000).fadeOut();
});
