Laravel确定何时更新字段

Question

I want to diplay when my status field was updated how is it possible? Timestamps are not solution in this situation. my model

Answer 1

You cannot determine when a specific model attribute has been last updated without some tracking of the attribute changes.

If timestamps are not an option, I'd highly suggest you to opt for an audit log system that has a database composed like this:

id | entity_id | entity_type | attribute | old_value | new_value | created_at

Everytime an attribute changes, you create a new entry in the database, logging the old and the new value.

You can also add a new column to specify who has made a particular change!
