var ObjectId = Schema.ObjectId;
var CategorySchema = new Schema({

CategorySchema.statics.getNested = function(parentSlug,cb){
this.findOne({slug:parentSlug},function(err,cat){
if (err) {
cb(err);
} else {
this.find({parentId: cat._id},function(err, cats){
console.log(cats);
if (err){
cb(err);
} else {
cb(null,cats);
}
});
}
});
};
我尝试了{parentId: ObjectId(cat._id)}
,但这也不起作用// ObjectId(cat._id) -> undefined
如何通过_id
搜索mongoose?
更新<!/强>
查询
Category.find({parentId:'5634eeb38a33a59c1dffa6ee'}, function(err,res){
console.log(res);
});
工作正常,但如何?

应为min-height: -moz-min-content; // not implemented
min-height: -webkit-min-content // works for opera and safari
min-height: min-content // works for chrome

您的架构中有不正确的ObjectId类型,您应该使用Schema.Types.ObjectId而不是Schema.ObjectId,因为它们返回不同的值:
http://mongoosejs.com/docs/api.html#schema-objectid-js http://mongoosejs.com/docs/api.html#types-objectid-js
如果将ObjectId定义替换为以下
var ObjectId = Schema.Types.ObjectId;
您的代码应该正常运行。
