使用节点填充 mongo 中的对象数组

Question

I have this model

var clienteSchema = new mongoose.Schema({
    nome:            String,
    profissao:       String,
    estado_civil:    String,
    data_nascimento: String,
    cpf:             String,
    cidade:          String,
    endereco:        String,
    data_cadastro:   {
        type:    Date,
        default: Date.now
        },
    telefone:        String,
    estadias:        [{
        type: mongoose.Schema.Types.ObjectId,
        ref: "Estadia"
    }]
});

I am trying this to populate but to no avail.

Cliente.findById({ _id: req.params.id }).populate("estadias.Estadia").exec((err,cliente)=>{

How I can do this?

您只需要使用函数 .populate ("estadias") 但首先确保您的数据库中有数据，在这种情况下，我正在尝试但在创建文档时出现另一个错误使其为空
