• Field types

Project Creation

• Set up files:

django-admin.py startproject <projectname>
cd <projectname>
django-admin.py startapp <appname>
python manage.py runserver

• Configure settings:

# Edit settings.py
DATABASE_ENGINE = 'sqlite3' 
DATABASE_NAME = '<path to database file>' 
TIME_ZONE = '<Region>/<City>'

• Initialise database and set up admin user

python manage.py syncdb

• Add the application to the site:

# Edit settings.py
INSTALLED_APPS = (....)

• Edit urls.py

• Edit models.py

• Re-run python manage.py syncdb after modifying fields in models.py but be aware some changes may require deleting existing tables.

• TODO: Add admin setup instructions

Use Django ORM to generate table creation SQL

• Based on Table Creation Using ORM Standalone (which seems not to work with 1.0) and Using the Django ORM as a standalone component.

• Set up directory and files

## With directory layout:

settings.py
orm/
    __init__.py
    models.py

## With content:

# settings.py
DATABASE_ENGINE="sqlite3"
DATABASE_NAME="database_name.db"

INSTALLED_APPS = ('orm')


# models.py
from django.db import models

class SomeModel(models.Model):
   ...

• Run command from directory containing settings.py and orm directory (this will generate SQL):

django-admin.py sqlall --settings=settings --pythonpath=. orm

• Or run this command to actually create the database:

django-admin.py syncdb --settings=settings --pythonpath=.
