I am sorry, it was up all night working on this, and I was tired, and
honestly didn't want to piss anyone off or offend anyone.
...here is the actual code in question:
Snippet from models.py:
class DisneySpotType(models.Model):
name = models.CharField(max_length=128, primary_key=True)
def __unicode__(self):
return self.name
class Meta:
ordering = ['name']
verbose_name = 'Disney Spot Type'
verbose_name_plural = 'Disney Spot Types'
class DisneySpot(models.Model):
PARK_CHOICES = (
('MK','Magic Kingdom'),
('E','Epcot'),
('HS','Holywood Studios'),
('AK','Animal Kingdom'),
('O','Other'),
)
name = models.CharField(max_length=256)
description = models.TextField(DisneySpotType)
park = models.CharField(max_length=2, choices=PARK_CHOICES)
types = models.ManyToManyField(DisneySpotType)
location = models.ForeignKey(DisneyLocation)
altitude = models.DecimalField(max_digits=30,decimal_places=15)
horizontal_accuracy = models.DecimalField
(max_digits=30,decimal_places=15)
vertical_accuracy = models.DecimalField
(max_digits=30,decimal_places=15)
publish_date = models.DateTimeField('date published')
last_update_date = models.DateTimeField('date last updated')
def __unicode__(self):
return self.name
class Meta:
ordering = ['park','name','description','publish_date']
verbose_name = 'Disney Spot'
verbose_name_plural = 'Disney Spots'
get_latest_by = "publish_date"
The full admin.py:
from disney.models import *
from django.contrib import admin
from django.contrib.auth.models import User
class DisneySpotTypeAdmin(admin.ModelAdmin):
list_display = ('name',)
fields = ('name',)

verbose_name = 'Tag'
verbose_name_plural = 'Tags'
class DisneySpotTagAdmin(admin.ModelAdmin):
list_display = ('tag','disney_spot')
class DisneySpotAdmin(admin.ModelAdmin):
list_display =
('name','park','description','publish_date','last_update_date')
list_filter = ('park','types',)
filter_horizontal = ('types',)
inlines = [
DisneySpotTagAdminInline,
]
class DisneyLocationAdmin(admin.ModelAdmin):
list_display = ('latitude','longitude',)
admin.site.register(DisneySpot,DisneySpotAdmin)
admin.site.register(DisneySpotType,DisneySpotTypeAdmin)
admin.site.register(DisneySpotTag,DisneySpotTagAdmin)
