Mongoose.js，除了_id&默认情况下来自查询结果的__v [英] Mongoose.js except _id & __v from query result by default

问题描述

除了查询结果中的字段，我可以像这样声明该字段:

I can except a field from query results declaring it like:

字段:{type:'string'，select:false}

field: {type: 'string', select: false}

但是可以通过_id和__v字段来做到这一点吗? 我尝试过

Is but it possible to do that with _id and __v field? I tried

_id:{select:假}

_id: {select: false}

但是似乎不起作用

推荐答案

您可以执行此操作，只要您还在模式定义中包括字段的type:

You can do this as long as you also include the type of the field in the schema definitions:

_id: {type: mongoose.Schema.ObjectId, select: false},
__v: {type: Number, select: false},

但是，这将阻止Mongoose在save上找到您的模型实例(并更新其__v)，除非您在find中明确地 include 这些字段.因此，请确保您知道自己在做什么.

However, that's going to prevent Mongoose from being able to find your model instance (and update its __v) on a save unless you explicitly include those fields in your find. So make sure you know what you're doing.
