How to process binary in model in yii2?

Question

MySQL

I want to store binary in the database, and work in the application as with a regular field. There is an idea to do transparent processing in beforeSave, but this does not look like a good solution because there is direct access to the field through the class, because there is a load method that will overwrite the field.
You need literally the following:
db (binary) <=> model (binary <=> text) <=> text.
What is the best way to do this transformation and where?

Answer 1

This task also hurt for a long time, as a result, it was decided through afterfind and insertInternal / updateInternal. Moreover, in insertInternal / updateInternal it is better not to modify the data through hex2bin, but to insert virtual changed values ​​into the database.
