如何替换 Laravel Builder 类

问题描述

我想用我自己的继承自 Laravel 构建器类替换它.我认为这就像 App::bind 一样简单，但似乎不起作用.我应该在哪里放置绑定以及在 Laravel 中这样做的正确方法是什么?

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?

这是我尝试过的:

我的建造者:

    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;
        }
    }

接下来我尝试在 bootstrap/start.php 文件中注册绑定，如下所示:

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;

推荐答案

IlluminateDatabaseEloquentBuilder 类是一个内部类，因此它不是依赖注入到 IlluminateDatabaseEloquentModel 类，但那里是硬编码的.

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

要做你想做的事，我会将 IlluminateDatabaseEloquentModel 扩展到 MyNamespaceDatabaseEloquentModel 类并覆盖 newEloquentBuilder 函数.

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);
}

然后将 MyNamespaceDatabaseEloquentModel 别名为 Eloquent 在 app/config/app.php
