TypeError:Test.findAll不是调用Mongoose架构的函数

Question

这是我的模式

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)

我打算把它用在这个功能上

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

但是我收到这个错误信息

TypeError: Test.findAll is not a function

如何访问该功能？

Answer 1

您将findAll添加为实例方法，而不是静态方法。如果你想为模型添加一个静态方法，那么你可以这样做：

testSchema.statics.findAll = async function (){
let tests = await this.find({});
return tests;
}
