When modifying a user via the api I wanted to use users.updated_at as criteria for the last update.
Now I noticed that it is not set anew upon all actions. Eg, when changing watched categories or watch 1st post categories, it is not.
Why not?
I do
add new users
put users to groups
delete users from groups
set the main group for a user
alter notification levels
set/unset a specific category for/from watching or watching 1st post
change the email address of a user
suspend/unsuspend users
and believed each of these actions should alter users.updated_at.
Is there another field that I’ve missed which can tell me when the settings of a user are last altered?
It looks like you’re right and that there is no updated_at for the category_users table. I’m not sure how to solve your problem, you could create a user_custom_field that you updated via the API, I think.
