Integration Without

Dependency

Friday, June 25, 2010

if 'staff' in global_settings.INSTALLED_APPS: from staff.models import StaffMember as AuthorModelelse: from django.contrib.auth.models import User as AuthorModel

from django.conf import settingsfrom django.db.models import get_modelAUTHOR_MODEL = getattr(settings, 'STORY_AUTHOR_MODEL', 'auth.user')AuthorModel = get_model(AUTHOR_MODEL.split('.'))

authors = models.ManyToManyField(AuthorModel, verbose_name=_('Authors'), blank=True, null=True)

Dynamic Relations

Integrate with

another app, if

available.

Or allow the

developer to

decide.

Either way,

implementation is

still simple.

if 'categories' in global_settings.INSTALLED_APPS: HAS_CATEGORIES = True from categories.fields import CategoryM2MField, CategoryFKFieldelse: HAS_CATEGORIES = False

if HAS_CATEGORIES: primary_category = CategoryFKField( related_name='primary_story_set') categories = CategoryM2MField(blank=True)

Optional Features

User Interface for

Content Managers is

Important

Menus are easily

customized by project

We took the edit inline to a new level

Friday, June 25, 2010

Still a few CSS issues

The quick edit form is specified in admin.py

Friday, June 25, 2010

Icon sets are included!

Friday, June 25, 2010
