我有一个布尔属性为“facturar”的模型。我无法通过GUI或控制台将此属性设置为true。出于某种原因，我可以通过控制台将其设置为false，而不是GUI。如果我尝试更新模型的任何记录，就会发生这种情况。类似的属性“facturar_proveedor”，也可以在GUI和控制台中将布尔值设置为true或false。什么可能导致这个奇怪的错误？

解决方案：我修改了模型中的回调。我删除了around_update回调并将其内容放在after_update中。
答案 0 :(得分：0)
你的PATCH日志似乎很奇怪，因为它没有做任何事情：
UPDATE "factura_items" SET "facturar" = $1, "updated_at" = $2 WHERE "factura_items"."id" = $3
并且有许多日志不是由您的控制器更新操作行为产生的，如：
(1.1ms) SELECT SUM("transaccions"."debito") FROM "transaccions"
