Propel filtering based on joined tables columns?

Question

How do I filter based on a joined table's columns in Propel?

Like:

$results = FooQuery::create()->joinBar()->filterByBarSurname('surname');

Answer 1

You have to use use method as described in the doc:

$results = FooQuery::create()
  ->useBarQuery()
    ->filterBySurname('surname')
  ->endUse()
  ->find();

// example Query generated for a MySQL database
$query = 'SELECT foo.* from foo
INNER JOIN bar ON foo.BAR_ID = bar.ID
WHERE bar.SURNAME = :p1'; // :p1 => 'surname'

If you have to use join(), I don't think you can use filterByXXX method but the old where:

$results = FooQuery::create()
  ->join('Foo.Bar')
  ->where('Bar.surname = ?', 'surname')
  ->find();
