如何在 Laravel 4 中手动创建一个新的空 Eloquent Collection [英] How to manually create a new empty Eloquent Collection in Laravel 4

问题描述

我们如何在 Laravel 4 中创建一个新的 Eloquent 集合，而不使用查询生成器?

有一个 newCollection() 方法可以被它覆盖，它并没有真正起作用，因为它只在我们查询一组结果时使用.

There is a newCollection() method which can be overridden by that doesn't really do job because that is only being used when we are querying a set result.

我想建立一个空的集合，然后用 Eloquent 对象填充它.我不使用数组的原因是因为我喜欢 Eloquent Collections 方法，例如 contains.

I was thinking of building an empty Collection, then fill it with Eloquent objects. The reason I'm not using array is because I like Eloquent Collections methods such as contains.

$c = new IlluminateDatabaseEloquentCollection;

$c->add(new Post);

或者你可以使用 make:
