php - hasMany returns null -

i'm on laravel 4.2, trying objects associative relation yet reason getting null.

models:

        class keg extends eloquent {            protected $fillable = ['beer_distribution_id', 'status', 'keg_size'];            public function beer_distribution()           {             return $this->belongsto('beerdistribution');           }          } 

        class beerdistribution extends eloquent {              protected $fillable = ['beer_id', 'distributor_id'];              public function kegs()             {                 return $this->hasmany('keg');             }          } 

my query:

        $distirbution = keg::find($tap->keg_id)->beer_distribution 

this query returns null: know keg object found , know object has beer_distribution_id.

i tried specifying foreign key in model so:

        class keg extends eloquent {            protected $fillable = ['beer_distribution_id', 'status', 'keg_size'];            public function beer_distribution()           {             return $this->belongsto('beerdistribution', 'beer_distribution_id');           }          } 

i thought might necessary since model camel case.

i know super simple, , in fact querying many relations succesfully through out application, reason 1 not working. thoughts on might missing?

the problem function name of relationship. laravel expects in camel case: beerdistribution().

change , should good. (you don't have specify foreign key, laravel convert camelcase snake_case)
