Hi,
What is the best way to assign permissions to users?
a) Each user has a list of permissions associated with that
user or
Nope
b) Each task/permission has a list of users that qualify or
Nope
c) Have a table with a row for each user/permission combination
Sort of. Create two tables a login table with user details and a
specific field for a ROLE.
Then create a roles table that lists the various permissions. I store
this in binary form in one field ( 10001111100100 ) where one means
permission granted and 0 means not granted. I assign the permissions
thru a form with checkboxes. You could also have permissons assigned
to individual fields in the table ( ie fields for update, select, add,
delete etc) to make things easier.
This process is significantly simpler when managing users, it's easier
to adjust permissions on one role than to edit a bunch of users when
something changes.
Thanks!
John
