Hi everyone,
I'm running Python 2.6.1, Django Trunk.
I have a model (Entry) with a ManyToMany (Categories). I need to be
able to iterate over these categories whenever my parent model is
saved.
I've tried overriding save_model in the admin, and adding a post_save
signal to Entry in order to be able to iterate over the categories.
The problem only occurs on an insert. If I do:
class Entry(models.Model):
name = models.CharField(max_length=100)
categories = models.ManyToManyField(Category)
class Meta:
verbose_name_plural = 'Entries'
def __unicode__(self):
return self.name
class EntryAdmin(admin.ModelAdmin):
def save_model(self, request, obj, form, change):
obj.save()
print obj.categories.all()
obj.categories.all() = []
However, when performing an update, I have a list of Category objects.
Is this a model lifecycle issue as far as when the ManyToMany gets
saved? What can I do to be able to access the list of categories when
the object is created?
TIA,
Brandon
