When a table that is related to in a QSqlRelationalTableModel gets
updated in some way (e.g. a new row, or the data is changed) then the
related model could not be updated without recreating the
QSqlRelationalTableModel.
Now, to get around this, select() can be called on the related model to
get it to be updated.

Instead of using a simple INNER JOIN, like:
SELECT a,b,rel.c FROM table1, table2 WHERE (table1.smthing =
table2.smthing)
which doesn't show row where foreign keys are NULL, allow use of LEFT
JOIN like:
SELECT a,b,rel.c FROM table1 LEFT JOIN table2 ON table1.smthing =
table2.smthing
The trick works also for multi-relational tables.
Just remember to use the new API setJoinMode.
