I have two models.
{{{
class A(models.Model):
pass
class B(models.Model):
is_success = models.BooleanField(null=True)
a = models.ForeignKey(A, on_delete=models.CASCADE)
}}}
And have defined admin for `A` class, with field `is_success` from `B`
class, in that way:
{{{
class AAdmin(admin.ModelAdmin):
list_display = ("is_success", )
@admin.display(boolean=True, ordering="is_success")
def is_success(self, obj):
newest_b = obj.b_set.first()
if newest_b:
return newest_b.is_success
else:
return
}}}
When I tried to order by column `is_success`, Django admin raises an
exception:
{{{

However, I discovered a strange behavior. I can add a SimpleFilter like
this:
{{{
class IsSuccessFilter(admin.SimpleListFilter):
title = "Is Success Filter"
parameter_name = "is_success"
def lookups(self, request, model_admin):
return [
("true", _("Yes")),
("false", _("No")),
("none", _("None")),
]
def queryset(self, request, queryset):
subquery = (
B.objects.filter(a_id=OuterRef("id"))
.values("is_success")[:1]
)
queryset = queryset.annotate(is_success=Subquery(subquery))
if self.value() == "true":
return queryset.filter(is_success=True)
elif self.value() == "false":
return queryset.filter(is_success=False)
elif self.value() == "none":
return queryset.exclude(is_success__isnull=True)
else:
return queryset
class AAdmin(admin.ModelAdmin):
list_display = ("is_success", )
list_filter = (IsSuccessFilter, )
@admin.display(boolean=True, ordering="is_success")
def is_success(self, obj):
newest_b = obj.b_set.first()
if newest_b:
return newest_b.is_success
else:
return
}}}
And now I can order by `is_success` until I turn on `facets` option. When
I click `Show counts` the exception occurs again, but without `Show
counts` ordering works correctly.
