无法读取未定义的属性'findAll'

Question

我正在使用findAll方法搜索所有用户，但它给出了此错误，无法读取未定义的属性"查找全部"。

用户.js

var user = require("../../models/user");
var sequelize = require('sequelize');
var constants = require("../../config/constants");
var requestHelper = require("../../helpers/request");
var responseHelper = require("../../helpers/response");
var model = require("../../models");
 var main = {
    title: "Hello World",
    statusCode: constants.HTTP.CODES.SUCCESS
}
main.signup = function (req, res, next) {
    var postBody = requestHelper.parseBody(req.body); //requestHelper converts into json format
    var responseBody = {}; `
   if (postBody.name != null && postBody.password != null) {
    model.user.findAll().then(function (emp) { // finding user 
          //...........working......//
                 });
            }
        });
    }
}
  module.exports = main;

我已经使用控制台.log(model.user(检查过，它说未定义，但无法找出导致它的问题用户型号.js

`'use strict';
module.exports = function(sequelize, DataTypes) {
  var user = sequelize.define('User', {
    name: DataTypes.STRING,
    password: DataTypes.STRING
  }, {
    classMethods: {
      associate: function(models) {
        // associations can be defined here
      }
    }
  });
  return user;
};

Answer 1

"model.user" 未初始化。可能的调试方法是将警报(或控制台.log设置为

alert('model.user is : '+model.user); 

或

console.log('model.user is : '+model.user);

根据这些警报，您将能够调试其中哪些是未定义的。如果您能够发现它是未定义的，请检查模型的源代码以查看是否正确定义了"user"。如果上述建议不起作用，请共享模型源。
