Laravel whereHas on multiple relationships

Question

Does anyone know if this new feature can be performed on multiple relationships?

For example, I have a query where I want to filter on not only the club name (relate

Answer 1

Yes that's possible.

The generated SQL will probably be:

SELECT * FROM ... WHERE (territory constraint) AND (homeClub constratint) OR (awayClub constraint)

This means that if awayClub constraint is satisfied, the line will be retrieved. I think you want to add a parenthesis to the generated sql:

SELECT * FROM ... WHERE (territory constraint) AND ((homeClub constratint) OR (awayClub constraint))

to do that, you need to nest both queries inside a where:

$ret->with('territory')->with('homeClub')->with('awayClub');
    $ret->whereHas('territory',function( $query ){
        $query->where('region','Australia');
    })
    ->where(function($subQuery)
    {   
        $subQuery->whereHas('homeClub', function ( $query ) {
            $query->where('name', 'Arsenal' );
        })
        ->orWhereHas('awayClub', function ( $query ) {
            $query->where('name', 'Arsenal' );
        });
    });
