I can not for the life of me figure out why my list_display works when the
django server is in DEBUG=True but not when it is in DEBUG=False. I am
using Django 1.4.3 (mod_wsgi 3.4/Python 2.7)
Here is the partial stack trace...
File
"/home/difuzi0n/webapps/wedding/lib/python2.7/django/db/models/manager.py",
line 116, in all
return self.get_query_set()
File
"/home/difuzi0n/webapps/wedding/lib/python2.7/django/db/models/fields/related.py",
line 565, in get_query_set
return super(ManyRelatedManager, self).get_query_set().using(
db)._next_is_sticky().filter(**self.core_filters)
File
"/home/difuzi0n/webapps/wedding/lib/python2.7/django/db/models/query.py",
line 624, in filter
return self._filter_or_exclude(False, *args, **kwargs)
File
"/home/difuzi0n/webapps/wedding/lib/python2.7/django/db/models/query.py",
line 642, in _filter_or_exclude

File
"/home/difuzi0n/webapps/wedding/lib/python2.7/django/db/models/sql/query.py",
line 1316, in setup_joins
"Choices are: %s" % (name, ", ".join(names)))
*FieldError: Cannot resolve keyword 'rsvp_guests' into field. Choices are:
city, event, first_name, id, last_name, state, street, zip_code*
My models looks as follows...
class Guest(models.Model):
first_name = models.CharField(max_length=50,
help_text="The Guest's given name.")
last_name = models.CharField(max_length=50,
help_text="The Guest's surname.")
...
def __unicode__(self):
return u'{} {}'.format(self.first_name, self.last_name)
class RSVP(models.Model):
event = models.ForeignKey(Event, verbose_name='RSVP Event')
guests = models.ManyToManyField(Guest, verbose_name='Guests',
related_name='rsvp_guests',
limit_choices_to = { 'id__in':
Event.objects.all().values('guests').query })
...
and the admin.py entry looks like so:
def guest_names(obj):
return u', '.join([unicode(guest) for guest in obj.guests.all()])
class RSVPAdmin(admin.ModelAdmin):
list_display = ['event', guest_names, 'max_invites', 'response',
'response_datetime', 'updated_by']
filter_horizontal = ('guests', )
thanks, in advance, for your help!!!
