how can I edit data in a view? Follow

If I have a single-table view, I can update fields that are identical in the original table using, e.g., psql. But DataGrip won't let me edit a view. Is there some hidden flag that will allow that? This is with DG 2017.3.7 with a Postgres 9.6 database

Example:

CREATE SCHEMA s;
CREATE TABLE s.t (a integer, b integer, c integer);
CREATE VIEW s.v AS (SELECT a + b as s, c FROM s.t);

INSERT INTO s.t VALUES (1, 1, 0), (1, 2, 1), (2, 3, 2);

SELECT * FROM s.v;
s  | c
----+---
 2 | 0
 3 | 1
 5 | 2

UPDATE s.v SET c=66 where s=5;

SELECT * FROM s.t;

a | b | c
---+---+---
1 | 1 | 0
1 | 2 | 1
2 | 3 | 5

Sure enough, s.t changed. I can even DELETE FROM s.v and everything is deleted from s.t. Why won't datagrip let me do that?

Thanks
