php - Laravel Eloquent Save to DB Using Create - Unhelpful Error -

i unhelpful error when try , insert new record in db. have idea start solve error?

user_id 

that's says. (this name of 1 of required fields in table i'm saving it's not descriptive.)

for reference here's code:

$data = array(     'user_id'=>1,     'post_type'=>'0',     'post_title'=>'blah',     'description'=>'blah');  //it fails on line $id = post::create($data); 

here's model looks like:

class post extends eloquent{     public static $rules = array(         'user_id'=>'required',         'post_type'=>'required',         'post_title' => 'required|max:25',         'description'=>'required'     );      public static function validate($data){         return validator::make($data, static::$rules);     }      public function user(){         return $this->hasone('user', 'id', 'user_id');     } } 

tried getting rid of relationships , validation in model. didn't work.

this called mass-assignment in laravel, need working on model set protected array called $guarded empty. add model.

protected $guarded = array(); 

what array does, can prevent attributes mass-assigned array, if don't want attribute filled model::create() method, need specify attribute in $guarded array.

if instead want specify fillable attributes, laravel's eloquent provides array called $fillable specify attributes want fill via mass-assigment way.
