                             Admin InterFace

FirstofAll to understand this chapter you have view the previous chapters from the older post so i kindly request you to view the older posts .The django admin interface is activated by default then we have to start the development server you need to make sure some modules are imported in the INSTALLED_APPS and MIDDLEWARE_CLASSES tuples of the pysite/settings.py file. for INSTALLED_APPS:
 

INSTALLED_APPS = (
'django.contrib.admin',
'django.contrib.auth',
 'django.contrib.contenttypes',
 'django.contrib.sessions',
 'django.contrib.messages',
'django.contrib.staticfiles',
 'myproj', )

for MIDDLEWARE_CLASSES

MIDDLEWARE_CLASSES = ( 
'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware',
)

In the previous chapters we have initiated the database if you have not initiated the database write the code as Before launching your server, to access your Admin Interface, you need to initiate the database

$ python manage.py migrate

If you don't have a superuser you will prompted to create a super user by this code you can create a super user

$ python manage.py createsuperuser

Then enter your desired username and press enter

Username: admin

you will then will be prompted to your desired email address

Email address: admin@example.com

The final step is to enter your password. You will be asked to enter your password twice, the second time as a confirmation of the first.

Password: **********
Password (again): *********
Superuser created successfully.

Now to start the Admin Interface, we need to make sure we have configured a URL for our admin interface. Open the pysite/url.py and you should have something like

from django.conf.urls import patterns, include, url
from django.contrib import admin
admin.autodiscover()
 urlpatterns = patterns('',
 # Examples:
 # url(r'^$', 'pysite.views.home', name = 'home'),
 # url(r'^blog/', include('blog.urls')),
 url(r'^admin/', include(admin.site.urls)), )

START THE DEVELOPMENT SERVER

Start the development server and explore it. If the server is not running start it like so:

$ python manage.py runserver

Now go to this url on your browser "http://127.0.0.1:8000/admin/" and you will see the login screen of the django admin

now try to login with the superuser account you created earlier

You should see a few types of editable content: groups and users. They are provided by django.contrib.auth, the authentication framework shipped by Django.and all registered models in your app you can administrate all of them. The interface gives you the ability to do at least the "CRUD" (Create, Read, Update, Delete) operations on your models.
Earlier we have created our models now we didn't see it here for that we need to add some code on the myproj.py/admin.py like so

from django.contrib import admin
from .models import Mytable
admin.site.register(Mytable)

Now that we’ve registered Mytable, Django knows that it should be displayed on the admin index page: there will be the mytable under the myproj created for you
if you click the mytable you will be directed to the table were you can edit the previously created table with website , mail ,name and phone number given
THE MAIN POINTS TO NOTE HERE ARE
  

• The form is automatically generated from the Question model. 

•  The different model field types (IntegerField, CharField) correspond to the appropriate HTML input widget. Each type of field knows how to display itself in the Django admin. 

The bottom part of the page gives you a couple of options:
             

• Save – Saves changes and returns to the change-list page for this type of object.

• Save and continue editing – Saves changes and reloads the admin page for this object. 

• Save and add another – Saves changes and loads a new, blank form for this type of object.

• Delete – Displays a delete confirmation page

Friends after you have familiarized with the models API and the admin site,continue to my next post
