Comment:
I think we should reopen this and fix an issue with current
`RelatedFieldListFilter`. For example currently to add `Not Empty` choice
you need to do this
{{{
#!div style="font-size: 80%"
Code highlighting:
{{{#!python
class NotEmptyFilter(admin.RelatedFieldListFilter):
@property
def include_empty_choice(self):
# FIXME: empty value selected incorrectly override in choices
return False
def has_output(self):
return super().has_output() + 2
def choices(self, changelist):
yield from super().choices(changelist)
yield {
'selected': self.lookup_val_isnull == 'True',
'query_string': changelist.get_query_string(
{self.lookup_kwarg_isnull: 'True'}, [self.lookup_kwarg]
),
'display': _('Empty'),
yield {
'selected': self.lookup_val_isnull == 'False',
'query_string': changelist.get_query_string(
{self.lookup_kwarg_isnull: 'False'}, [self.lookup_kwarg]
),
'display': _('Not Empty'),
}
}}}
}}}
But you should be able to do just
{{{
#!div style="font-size: 80%"
Code highlighting:
{{{#!python
class NotEmptyFilter(admin.RelatedFieldListFilter):
def has_output(self):
return super().has_output() + 1
def choices(self, changelist):
yield from super().choices(changelist)
yield {
'selected': self.lookup_val_isnull == 'False',
'query_string': changelist.get_query_string(
{self.lookup_kwarg_isnull: 'False'}, [self.lookup_kwarg]
),
'display': _('Not Empty'),
}
}}}
}}}
Currently this is not possible because of `bool(self.lookup_val_isnull)`
check in selected for `Empty` choice, and if we add `Not Empty` choice
like in second example we will get both `Empty` and `Not Empty` choices
rendered as selected on `Not Empty`
