python - Django smart select many to many field filter_horizontal/filter_vertical does not allow chaining -

-

hi doing project in django 1.10. project using django-smart-select chaining input in admin panel. works fine. many many fields chaining if use filter_horizontal/filter_vertical chaining not work more. there no solution in there github page. how can solve problem? there app this?

i have same problem , solved in fork library: https://github.com/jorgecorrea/django-smart-selects can see in readme version, way use in horizontal mode mi fork: models.py

from smart_selects.db_fields import chainedmanytomanyfield  class publication(models.model):     name = models.charfield(max_length=255)  class writer(models.model):         name = models.charfield(max_length=255)         publications = models.manytomanyfield('publication',                                                blank=true,                                               null=true)  class book(models.model):         publication = models.foreignkey(publication)         writer = chainedmanytomanyfield(             writer,             horizontal=true,             verbose_name='writer',             chained_field="publication",             chained_model_field="publications",         )         name = models.charfield(max_length=255)

with little change can use django horizontal mode view, not add field admin filter_horizontal change not needed: admin.py

@admin.register(book) class bookadmin(admin.modeladmin):     filter_horizontal = ('writer',)    # don't because changing widget.
