mongodb - 为什么Mongoose在创建collection的时候会自动添加s和小写?

Question

我没有在文档里找到相关的解释,求指点,谢谢.

mongoose是通过model来创建mongodb中对应的collection的，mongoose在内部创建collection时将我们传递的collection名（‘friendimpression’）小写化，同时如果小写化的名称后面没有字母——s,则会在其后面添加一s,针对我们刚建的collection,则会命名为：friendimpressions。

1、从文档中找到：

The first argument is the singular name of the collection your model is for. Mongoose automatically looks for the plural version of your model name. Thus, for the example above, the model Tank is for the tanks collection in the database. The .model() function makes a copy of schema. Make sure that you've added everything you want to schema before calling .model()!
