I have a customer requirement/desire. The system is (among other things)
essentially a employee time sheet. The manager wants for an employee to not
be able to modify a given row in the table they enter time into once it is
committed. I personally see issues with this, but I am willing to try to give
him what he wants. If it creates issues we can sort them out, once he sees
the issues.
The only way I see to do this is to add a column (call it lock). I will
then set this up as a default entry with a value of TRUE. The form the
employee uses to enter this will, of course, not display this column. The
I will create a function that on UPDATE, checks for the presence of the 1 in
this row, and rejects the update. Then I will give the manager a form where
he can set this flag to FALSE.
Looks ugly, and convulsed to me.
Is here a more "database native" way to handle this?
Depends on who is doing the database record changes.
In other words are there defined roles:
https://www.postgresql.org/docs/11/sql-createrole.html
for the object(table) and the entity working with the table?
OK, maybe I could set up the "user" role, such that it does not have the
UPDATE permission on this table, just the INSERT one? Of course the "admin"
role would have the UPDATE attribute for this table.
'user' should also have SELECT if you want them to see their records.
Make sense?
Yes.
