Laravel hasMany relationships don't work as expected

I'm new to Laravel model relationships and I'm trying to learn it by building a basic forum system. I'm trying to get the fours to belong to the forum categories:

Here is my ForumCategory model:

class ForumCategory extends Eloquent {

    protected $table = 'forum_categories';

      public function forums()
    {
        return $this->hasMany('Forum','category_id');
    }
}

The forum model name is forum and the foreign key is category_id.

Here is the forum model:

class Forum extends Eloquent {

    protected $table = 'forums';
}

This is how I try to test it:

$category=ForumCategory::find(1);
print_r($category->forums());

But what I get from print_r is a very large object, not related forums.

Thank.

What you want is a dynamic Eloquent property when calling the relationship.

To illustrate:

// Return you chainable queries    
$query = ForumCategory::find(1)-> forums()->... 
// To actually return the forums
// You need to use get() since it is a chainable query builder
$query = ForumCategory::find(1)-> forums()->get();

// BUT, you can use Eloquent dynamic property
// Notice no '()'
// Return you collection of forums
$patientsCollection = ForumCategory::find(1)-> forums;


Essentially, you have a QueryBuilder.
