demonstrate cannot change column in BeforeUpdate()

[rverdile]

Explain your user case and expected results

I would like to be able to use BeforeUpdate() to modify a column value, before updating. For example, I may want to trim any whitespace on the value before updating it in the database. The functionality is possible with the BeforeCreate() hook, but it does not seem to be possible with the BeforeUpdate() hook.

in my code example, you can see I create a user " jinzhu ". In the BeforeCreate() method, I trim the whitespace and update the value, and the query uses the updated value.

In my code example, I update the user to the name " tux ". In the BeforeUpdate() method, I trim the whitespace and update the value, but the actual update query still uses the original value. I would expect it to use the updated value.
