Comment:
As can be seen above, problem occurs when there is one or more
intermediate abstract classes between the one containing the
`verbose_name_plural` definition and the non-abstract one.
In the example posted by the OP, the `CategoryMarkup` model needs to
define its own inner `Meta` class basause it has to explicitely specify it
is a abstract class. Then, if it is desired it inherits the
`verbose_name_plural` attribute from `CategoryBase` we need to make sure
it extends its Meta inner class by subclassing it:
{{{
#!python
class CategoryBase(models.Model):
class Meta:
abstract = True
verbose_name_plural = u'CategoryBase verbose_name_plural'
class CategoryMarkup(CategoryBase):
class Meta(CategoryBase.Meta):
abstract = True
#...
}}}
OP didn´t paste his models se we don't know if he was taking this in
account.
But even if this usage error isn't present in user's models there is a
Django bug (`Category.verbose_name_plural` values shown are
<django.utils.functional.__proxy__...` as above and they evaluate to
"Categorys" in the admin). IMHO it should treat `verbose_name_plural` in a
way consistent with `verbose_name`. I'm changing the component field of
this ticket accordingly.
