Flying with Django

Setting up some things

Create an App

$ python manage.py startapp regisApp

✗ $ ls regisApp✗ __init.py__ models.py✗ tests.py views.py

$ python manage.py startapp regisApp

✗ $ ls regisApp✗ __init.py__ models.py✗ tests.py views.py

Setting up the Database

settings.py is used to...

✗ ...✗ 'ENGINE':'...sqlite3','NAME':'/dir/project/site/name.db',

✗ ...✗ $ python manage.py syncdb

✗ ...✗ 'ENGINE':'...sqlite3','NAME':'/dir/project/site/name.db',

✗ ...✗ $ python manage.py syncdb

Our example

Models: Relationships

● Modify models.py:● Relationships:

● Many-to-many:field = models.ManyToManyField(Object)

● Many-to-one: field = models.ForeignKey(Object)

● One-to-one: field = models.OneToOneField(Object)

Models: Fields● Fields:

● Text:field = models.TextField()

● Varchar: field = models.CharField(max_length=000)

● Integer: field = models.IntegerField()

● Boolean: field = models.BooleanField()

Setting up the Models

settings.py is used to...

✗ ...✗ INSTALLED_APPS = (✗ 'enli-test.regisApp',

...

$ python manage.py sql regisApp✗ $ python manage.py syncdab

✗ ...✗ INSTALLED_APPS = (✗ 'enli-test.regisApp',

...

$ python manage.py sql regisApp✗ $ python manage.py syncdab

Magic?

Django include an admin s ite

settings.py again...

✗ ...✗ INSTALLED_APPS = (

'django.contrib.admin',

...

$ python manage.py syncdb

✗ ...✗ INSTALLED_APPS = (

'django.contrib.admin',

...

$ python manage.py syncdb

Django include an admin s ite

Edit urls.py

✗ $ python manage.py runserver✗ $ python manage.py runserver
