QSqlTableModel() empty on Ubuntu but works on Windows ?

SGaist

Would you be able to provide a small step by step guide to reproduce your test database ? Meaning the command you are currently using on your Linux machine to create the role and the database.

@SGaist Hi, I just use psql to create the database/table/user.

CREATE DATABASE my_db
    WITH 
    OWNER = postgres
    ENCODING = 'UTF8'
    TABLESPACE = pg_default
    CONNECTION LIMIT = -1;

CREATE ROLE my_user WITH
  LOGIN
  NOSUPERUSER
  INHERIT
  NOCREATEDB
  NOCREATEROLE
  NOREPLICATION
  ENCRYPTED PASSWORD 'md5hidden';

CREATE TABLE public.my_table
(
    example_column character varying COLLATE pg_catalog."default",
)

TABLESPACE pg_default;

ALTER TABLE public.my_table OWNER to postgres;

GRANT INSERT, SELECT, DELETE ON TABLE public.my_table TO my_user;

So for example:

sudo -u postgres psql -c 'one of the above blocks of code'

So here my_db is the database name, my_user is the role I'm using to access the table and my_table is the table name.

R-P-H

Is there anything else I can try ?

Sorry I did not had time to test the database.

One thing that you could try (I don't think it would change anything but worth a try), reorder the database setup and add your custom role and it setup both at the end.

I guess I could try that but why would the error be

QSqlError("", "Unable to find table logs", "")

then ?

Gut feeling: PostgreSQL namespace.

I had a look, but I don't quite understand how it applies to this...

SGaist

The database role must have access to the namespace in order to access the relation it contains.

There might be a glitch there.

Yet the same role (same exact application/code) works fine on Windows ?

Upgrading to Qt Version 5.15+ solved the issue.
