Laravel Relationships

Question

I\'ve been looking over relationships in Laravel 4 in the documentation and I\'m trying to work out the following.

I have a table in my database called \'events\'. T

Answer 1

You need to specify in both models a relationship. belongsTo() in one, hasOne() in the other, since you are using one-to-one relationship

class Course extends Eloquent{

    protected $table = 'courses';


    public function event()
    {
        return $this->belongsTo('Event');
    }
}


class Event extends Eloquent {

    protected $table = 'events';

    public function course()
    {
        return $this->hasOne('Course');
    }

}

Then calling it in the route or the controller would be as following:

Course of specific event (in this case with id of 1)

$course = Event::find(1)->course;

Event of specific course (in this case with id of 1)

$event = Course::find(1)->event;

Please refer to the Laravel 4 documentation, section Eloquent ORM: http://laravel.com/docs/eloquent#one-to-one

Answer 2

This is basically the same answer as @Marko Aleksić, but with the hasOne() and belongsTo() relationships the right way around.

class Course extends Eloquent{

    protected $table = 'courses';


    public function event()
    {
        return $this->hasOne('Event'); // links this->id to events.course_id
    }
}


class Event extends Eloquent {

    protected $table = 'events';

    public function course()
    {
        return $this->belongsTo('Course'); // links this->course_id to courses.id
    }

}
