類型錯誤：Test.findAll 不是函數 callinf Mongoose Schema

Question

這是我的架構

const mongoose = require('mongoose');
const Schema = mongoose.Schema;

const testSchema = Schema({
    title: String,
    questions: [],
    user: Schema.Types.ObjectId
});

testSchema.methods.findAll = async function (){

    let tests = await this.find({});

    return tests;
}


module.exports = mongoose.model('Test',testSchema)

我正在嘗試在此功能上使用它

showMainPage = function(req, res){
    var tests = Test.findAll();
    console.log(tests);
    res.render('main/index.twig', {username:req.user.username});
}

但我收到此錯誤消息

TypeError: Test.findAll is not a function

如何訪問該功能？

Answer 1

您將findAll添加為實例方法而不是靜態方法。 如果您希望為模型添加靜態方法，則可以執行以下操作：

testSchema.statics.findAll = async function (){

    let tests = await this.find({});

    return tests;
}
