I have upgraded my FuelPHP in an existent project.
After that, i realize that delete a model fall in error.
It seems like some related model are updated instead to be deleted in cascade.
I suppose it try to update FK, but with a NULL value. Ex : Fuel\Core\Database_Exception [ 1048 ]:
The field 'product_id' can't be empty (null) [ UPDATE `product_units` SET `product_id` = null, `updated_at` = '2016-03-24 11:18:27' WHERE `id` = '16' ]
I didn't find in the changelogs some information about that. Could you help me ?
