Laravel : Handle findOrFail( ) on Fail

Question

I am looking for something which can be like findOrDo(). Like do this when data not found. Something could be like

Model::findOrDo($id,function(){
   return \"Da

A little later for the party, from laravel 5.4 onward, Eloquent Builder supports macros. So, I would write a macro (in a separate provider) like follows.

Builder::macro('firstOrElse', function($callback) {
   $res = $this->get();

   if($res->isEmpty()) {
       $callback->call($this);
   }

   return $res->first();
});

I can then do a retrieval as follows.

$firstMatchingStudent = DB::table('students')->where('name', $name)
    ->firstOrElse(function() use ($name) {
        throw new ModelNotFoundException("No student was found by the name $name");
    });

This will assign the first object of the result set if it is not empty, otherwise will adapt the behaviour I pass into the macro as a closure (throw Illuminate\Database\Eloquent\ModelNotFoundException in this case).

For the case of a model also this would work, except that models always return the builder instance.
