不明白这个东西是什么??
Eloquent与传统MVC模型中的M(模型)的关系是什么??
可不可以说Eloquent是一种已经将数据注入到模型的模型吗?

Eloquent 是 Laravel 中实现的一个 ORM 框架,原话为:

The Eloquent ORM included with Laravel provides a beautiful, simple
ActiveRecord implementation for working with your database.

所以 Eloquent 是作为 Laravel ORM 框架的一个名称,其命名空间下包括 Model、Relationship、Builder 等类的实现,这些类提供数据到对象的映射,同时提供模型间关系(Relationship)的支持。

比如 M$ 的 Entity Framework,同样是一个 ORM 框架,其中包含模型和关系查询、操作等。

更多关于 Eloquent 的可以参考 API:https://laravel.com/api/5.2/Illuminate/Database/Eloquent.html

并非非常专业的回答。
