I have two models. My first one is:

<?php namespace App;

use Illuminate\Database\Eloquent\Model;


class Fixture extends Model {

    public function match()
    {
        return $this->hasOne('App\Matchinfo');
    }

    public function result()
    {
        return $this->hasOne('App\Result');
    }

}

and the second one:

<?php namespace App;

use Illuminate\Database\Eloquent\Model;


class Matchinfo extends Model {

    protected $table =  'matchinfo';

    public function fixture()
    {
        return $this->belongsTo('App\Fixture');
    }

}

When I run $fixture = Matchinfo::where('mdate','<','NOW()')->get(); it picks up the data just fine. However when I then try $fixture->fixture()->where('id','fixture_id')->get(); all I get is

FatalErrorException in DynamicPagesController.php line 15: Call to undefined method Illuminate\Database\Eloquent\Collection::fixture()

I'm new to relationships in eloquent so I'm really stuck. It looks like it should be ok. Can someone point me in the right direction please?
