php - How to replace the Laravel Builder class

Question

I want to replace the Laravels builder class with my own that's extending from it. I thought it would be as simple as matter of App::bind but it seems that does not work. Where should I place the binding and what is the proper way to do that in Laravel?

This is what I have tried:

my Builder:

    use IlluminateDatabaseEloquentBuilder as BaseBuilder;
    class Builder  extends  BaseBuilder
    {

        /**
         * Find a model by its primary key.
         *
         * @param  mixed  $id
         * @param  array  $columns
         * @return IlluminateDatabaseEloquentModel|static|null
         */
        public function find($id, $columns = array('*'))
        {
            Event::fire('before.find', array($this));
            $result = parent::find($id, $columns);
            Event::fire('after.find', array($this));
            return $result;
        }
    }

And next I tried to register the binding in bootstrap/start.php file like this :

$app->bind('Illuminate\Database\Eloquent\Builder', 'MyNameSpace\Database\Eloquent\Builder');
return $app;

IlluminateDatabaseEloquentBuilder class is an internal class and as such it is not dependency injected into the IlluminateDatabaseEloquentModel class, but kind of hard coded there.

To do what you want to do, I would extend the IlluminateDatabaseEloquentModel to MyNamespaceDatabaseEloquentModel class and override newEloquentBuilder function.

public function newEloquentBuilder($query)
{
   return new MyNamespaceDatabaseEloquentBuilder($query);
}

Then alias MyNamespaceDatabaseEloquentModel to Eloquent at the aliases in app/config/app.php
