Hello,

admin configuration:
{{{
class EstadosListFilter(admin.SimpleListFilter):
title = _("Estados Licitación")
parameter_name = "cantidad_estados"

def lookups(self, request, model_admin):
return [
("1", _("1")),
("2", _("2")),
]

def queryset(self, request, queryset):
if self.value() == "1":
return queryset.filter(_cantidad_estados=1)
elif self.value() == "2":
return queryset.filter(_cantidad_estados=2)
return queryset


@admin.register(Licitaciones)
class LicitacionesAdmin(admin.ModelAdmin):
ordering = ["created_at"]

exclude = ['user', 'file_path']

list_display = ['CodigoExterno', 'empresa__NombreEmpresa', 'date',
'CodigoEstado', 'FechaCierre', 'Nombre',
'cantidad_productos', 'cantidad_items',]

search_fields = ["CodigoExterno", 'empresa__NombreEmpresa',
"productos__NombreProducto",
'licitacion_proveedores__NombreProveedor']

inlines = [ProveedoresInline, LicitacionesDetallesActiveInline,
LicitacionesDetallesNoActiveInline, ItemsActiveInline,
ItemsNoActiveInline]

list_filter = (
"CodigoEstado", ('date', admin.DateFieldListFilter),
EstadosListFilter)

show_facets = admin.ShowFacets.ALWAYS

def get_queryset(self, request):
cantidad_productos_subq =
Licitaciones.objects.filter(CodigoExterno=OuterRef(
"CodigoExterno")).annotate(__cantidad_productos=Count('productos')).values('__cantidad_productos')

cantidad_estados_subq =
Licitaciones.objects.filter(CodigoExterno=OuterRef("CodigoExterno")).annotate(
__cantidad_estados=Count('licitacion_detalle')).values('__cantidad_estados')

cantidad_items_subq =
Licitaciones.objects.filter(CodigoExterno=OuterRef("CodigoExterno")).annotate(
__cantidad_items=Count('licitacion_items',
filter=Q(licitacion_items__active=True))).values('__cantidad_items')

''' solo muestra licitaciones a las cuales se les ha traido el
detallle'''
qs = super(LicitacionesAdmin, self).get_queryset(
request).filter(licitacion_detalle__isnull=False)

qs = qs.annotate(
_cantidad_productos=Subquery(cantidad_productos_subq),
_cantidad_estados=Subquery(cantidad_estados_subq),
_cantidad_items=Subquery(cantidad_items_subq)
)
return qs

def cantidad_productos(self, obj):
return obj._cantidad_productos
cantidad_productos.short_description = 'Productos'
cantidad_productos.admin_order_field = '_cantidad_productos'

def cantidad_items(self, obj):
return obj._cantidad_items
cantidad_items.short_description = 'Items'
cantidad_items.admin_order_field = '_cantidad_items'

def cantidad_estados(self, obj):
return obj._cantidad_estados
cantidad_estados.short_description = 'Estados'
cantidad_estados.admin_order_field = '_cantidad_estados'

def empresa__NombreEmpresa(self, obj):
return obj.empresa.NombreEmpresa
empresa__NombreEmpresa.short_description = 'Razón Social'
}}}

At this point, LicitacionesAdmin, correctly displays EstadosListFilter and
its number of facets in change_list view. But when performing a search, it
throws the following error:

{{{
ProgrammingError at /admin/mpublico/licitaciones/

invalid reference to FROM-clause entry for table "mpublico_licitaciones"
LINE 1: ...= U1."licitacion_id") WHERE U0."CodigoExterno" = ("mpublico_...
^
HINT: Perhaps you meant to reference the table alias "u0".
}}}

But changing to:

{{{
show_facets = admin.ShowFacets.NEVER
}}}

Performs the search without any errors

On the other hand, when the option is set to ALLOW, search also works,
the error in this case appears when clicking on show facets
