Re: newforms-admin weird error ( 'str' object has no attribute '_default_manager' )
I am experiencing same error message with r8053, however my situation is a bit different: - commenting out fieldsets definition doesn't help, - everything works perfectly on local dev server and fails deployed through mod_wsgi and mod_python (I didn't try with fcgi) I managed to narrow down the problem to two models that are causing the problem, both have custom managers and one have overriden queryset method. Any help would be highly appreciated as I spent a lot of time on chasing this and really have no idea where I could look for possible solution.

Splitting my admin settings into admin.py modules, and updating to the latest trunk fixed this problem. - Bram --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Do you know what level you updated from? That's always handy to know when
trying to pinpoint when a problem was introduced.

So it's got something to do with validation. Do you know if it worked at
all after validation of ModelAdmin was added (r7929) and has broken
subsequently, or if it broke as soon as ModelAdmin validation was added?

Determining which part of the fieldsets definition generates the error would
be helpful. You might be able to determine it by looking at the local vars
in the debug page. Alternatively you could experiment with removing pieces
of it to see which field is causing the error. Basic fieldsets validation
works (I'm sure it's got tests and I have models that use it and still work
on current newforms-admin), so it's something specific to your model. If
you could strip your models down to a reasonably simple testcase that
displays the error it would be helpful.

newforms-admin weird error ( 'str' object has no attribute '_default_manager' )
Hello all,
just updated to latest newforms-admin (r7947) and
This is the admin for one of my (rather large) models:
class Sound(SocialModel): # SocialModel is a model that defines some
GenericRelation
user = models.ForeignKey(User)
# snip
license = models.ForeignKey(License)
geotag = models.ForeignKey(GeoTag, null=True, blank=True, default=None)
#snip
sources = models.ManyToManyField('self', symmetrical=False,
related_name='remixes', blank=True)
pack = models.ForeignKey('Pack', null=True, blank=True, default=None)
#snip
type = models.CharField(db_index=True, max_length=4,
choices=SOUND_TYPE_CHOICES)
#
class SoundAdmin(admin.ModelAdmin):
raw_id_fields = ('user', 'pack', 'sources', 'geotag')
list_display = ('id', 'user', 'original_filename', 'license')
list_filter = ('processing_state', 'moderation_state', 'license')
fieldsets = (
(None, {'fields': ('user', 'created', 'modified')}),
('Filenames', {'fields': ('original_path', 'base_filename_slug')}),
('User defined fields', {'fields': ('description', 'license',
'geotag', 'original_filename', 'sources', 'pack')}),
('File properties', {'fields': ('md5', 'type', 'duration',
'bitrate', 'bitdepth', 'samplerate', 'filesize', 'channels')}),
('Moderation', {'fields': ('moderation_state',
'moderation_date', 'moderation_bad_description')}),
('Processing', {'fields': ('processing_state',
'processing_date', 'processing_log')}),
)
admin.site.register(Sound, SoundAdmin)
And this is the error I get when validating:
