I have three tables,
users - all users of my web site
facilities - facilities available on my web site
facility_levels - access levels per user/facility.
One of my facilities is a document library (f_id = 22)
For this facility I have the levels
select * from facility_levels where fl_f_id=22 order by fl_level;
fl_f_id | fl_level | fl_desc
---------+----------+-------------- 22 | 1 | Read Only 22 | 2 | Add Versions 22 | 3 |
Amend
(3 rows)
This sets the global access level for the Document Library per user.
I now want to add authentication control on a document or folder level. For
this I need to create a table library_document_user_level
u_id - user id
ld_id - library document id
fl_level - level
The foreign key constraint on fl_level needs to check facility_levels for
fl_f_id = 22 as well as fl_level existing.
I've googled this but can't find a suitable solution. Can anyone help please.
