Adding Authentication to a Django site

1. Put 'django.contrib.auth' and 'django.contrib.contenttypes' in your INSTALLED_APPS setting. (The Permission model in django.contrib.auth depends on django.contrib.contenttypes.).  These should be the default settings anyway after installing Django.
2. Run the command manage.py syncdb.

Add @login_required before each view:

e.g.

@login_required (login_url='/accounts/login/')

def myview(request, event_id):

    ...

    return render(request, ...

This redirects the user to /accounts/login, so add the following to the top level urls.py:

    url(r '^accounts/login/$' , 'django.contrib.auth.views.login'),

The default login page template is then at registration/login.html:

e.g. 

{% extends "base.html" %}

{% load url from future %}

{% if form.errors %}

<p>Your username and password didn 't match. Please try again.</p>

{% endif %}

<form method="post" action= "{% url 'django.contrib.auth.views.login' %}">

{% csrf_token %}

<table align="center">

<tr>

    <td>{{ form.username.label_tag }}</td>

    <td>{{ form.username }}</td>

</tr>

<tr>

    <td>{{ form.password.label_tag }}</td>

    <td>{{ form.password }}</td>

</tr>

</table>

<div style="text-align: center;"><input type="submit" value= "login" /></div>

<div style="text-align: center;"><input type="hidden" name= "next" value="{{ next }}" /></div>

</form>

The following URLs are used for password reset

(r'^accounts/password/reset/$', 'django.contrib.auth.views.password_reset', 
        {'post_reset_redirect' : '/accounts/password/reset/done/'}),(r'^accounts/password/reset/done/$', 'django.contrib.auth.views.password_reset_done'),(r'^accounts/password/reset/(?P<uidb36>[0-9A-Za-z]+)-(?P<token>.+)/$', 'django.contrib.auth.views.password_reset_confirm', 
        {'post_reset_redirect' : '/accounts/password/done/'}),(r'^accounts/password/done/$', 'django.contrib.auth.views.password_reset_complete'),

The following templates are required. These are referred to from the url patterns above, plus one for  email.

• registration/password_reset_complete.html
• registration/password_reset_confirm.html
• registration/password_reset_done.html
• registration/password_reset_form.html
• registration/password_reset_email.html
