Hobo sets acting_user only when checking permissions (including in the life
cycle). Google acting_user in this group to get a more complete explanation.

I don't think this does what you think it does. Since Hobo applications are
Rails applications, and Rails reads the database schema to get the field names,
these field names will be available in the application regardless of whether
the "fields" section is there or not. Furthermore, when a hobo_migration is
run, there is no acting_user, which means that if there had not been an error
message, hobo_migration would have tried to remove these fields from the
database.
It would be helpful if you explained what you are trying to do.
