How to change template based on user authentication in django

Question

If user successfully login i need to show one template. if user not login i need to show another template.

I created two templates one is base.html another one is base_login.html template.

IF user successfully login i need to call base_login.html other wise base.html. i am using below to achieve this. it's not giving expected result. How do achieve this?

{% if user.is_authenticated %}
        <p>Welcome {{ user.username }} !!!</p> 
        {% extends "base_login.html" %} 
{% else %}
        {% extends "base.html" %} 
{% endif %}

your qury's is correct but i need to know whether you create the "backends or not" if not create a custom backend then try it — Cadmus, Feb 16 '17 at 07:54
getting this error Exception Type: TemplateSyntaxError Exception Value: Invalid block tag on line 5: 'else'. Did you forget to register or load this tag? — Venkatesh Panabaka, Feb 16 '17 at 08:00
can you able to access the user in the template ? or try request.user ? — Cadmus, Feb 16 '17 at 08:00
{% if not user.is_authenticated %} something not auth {% else %} {{request.user.username}} {% endif %} — Cadmus, Feb 16 '17 at 08:02
i thinks the error is coming bcz of the tags are in together {% extends %} and {% else %} . can you remove the else tag try it. — Cadmus, Feb 16 '17 at 08:04

If your template goes invalid, I suggest you to it at the views.py, an example:

from django.shortcuts import render, render_to_response

def homepage(request):
    template_name = 'homepage.html'
    extended_template = 'base_login.html'

    if request.user.is_authenticated():
        extended_template = 'base.html'

    return render(
        request, template_name, 
        {'extended_template': extended_template, ...}
    )

# homepage.html
{% extends extended_template %}

{% block content %}
  {% if request.user.is_authenticated %}
    Hello {{ request.user }}
  {% endif %}
{% endif %}

Note: if function of render still doesn't work well, please try with render_to_response such as this answer: https://stackoverflow.com/a/1331183/6396981
