Question

I have a sort of map table that I need to perform multiple joins on to get other necessary data. How do you do that with Propel?

Sql would be something like:

SELECT * FROM table1
INNER JOIN table2 on table1.col1 = table2.id
INNER JOIN table3 on table1.col2 = table3.id

Answer 1

I just read their instructions wrong.

To do this you just do:

$result = ClassQuery::create()->joinWith('ClassTable.Instructor')->joinWith('Instructor.Department');

Then you do:

$instructor = $result->getInstructor();
$department = $instructor->getDepartment();

Then you can access the properties through the getters:

$prop = $department->getName();
