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 Illuminate\Database\Eloquent\Builder as BaseBuilder;
class Builder extends BaseBuilder
{
/**
* Find a model by its primary key.
*
* @param mixed $id
* @param array $columns
* @return \Illuminate\Database\Eloquent\Model|static|null
*/
public function find($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 $app;
Both of the answers are correct in some way. You have to decide what your goal is.
Change Eloquent Builder
For example, if you want to add a new method only for eloquent models (eg. something like scopes, but maybe a little more advanced so it’s not possible in a scope)
Create a new Class extending the Eloquent Builder, for Example CustomEloquentBuilder.
use Illuminate\Database\Eloquent\Builder;
class CustomEloquentBuilder extends Builder
{
public function myMethod()
{
// some method things
}
}
Create a Custom Model and overwrite the method newEloquentBuilder
use Namespace\Of\CustomEloquentBuilder;
use Illuminate\Database\Eloquent\Model;
class CustomModel extends Model
{
public function newEloquentBuilder($query)
{
return new CustomEloquentBuilder($query);
}
}
Change Database Query Builder
For example to modify the where-clause for all database accesses
Create a new Class extending the Database Builder, for Example CustomQueryBuilder.
use Illuminate\Database\Query\Builder;
class CustomQueryBuilder extends Builder
{
public function myMethod()
{
// some method things
}
}
Create a Custom Model and overwrite the method newBaseQueryBuilder
use Namespace\Of\CustomQueryBuilder;
use Illuminate\Database\Eloquent\Model;
class CustomModel extends Model
{
protected function newBaseQueryBuilder()
{
$connection = $this->getConnection();
return new CustomQueryBuilder(
$connection, $connection->getQueryGrammar(), $connection->getPostProcessor()
);
}
}
Laravel Version: 5.5 / this code is untestet
Illuminate\Database\Eloquent\Builder
class is an internal class and as such it is not dependency injected into the Illuminate\Database\Eloquent\Model
class, but kind of hard coded there.
To do what you want to do, I would extend the Illuminate\Database\Eloquent\Model
to MyNamespace\Database\Eloquent\Model
class and override newEloquentBuilder
function.
public function newEloquentBuilder($query)
{
return new MyNamespace\Database\Eloquent\Builder($query);
}
Then alias MyNamespace\Database\Eloquent\Model
to Eloquent
at the aliases
in app/config/app.php
