SequelizeJS错误：TypeError：User.FindAll不是函数

Question

我正在将sequelizejs与expressjs应用程序一起使用。

这里是我的用户模型的代码。

user.js

module.exports = function(sequelize, DataTypes) {
  var User = sequelize.define('User', {
    first_name: DataTypes.STRING,
    last_name: DataTypes.STRING,
    bio: DataTypes.STRING,
    email: DataTypes.STRING,
    profile_picture: DataTypes.STRING
  }, {
    classMethods: {
      associate: function(models) {
        // associations can be defined here
      }
    }
  }, {
    tableName: 'users'
  });
  return User;
};

const express = require( 'express' )
const router  = express.Router()
const User    = require( '../../models/user' )

router.get( '/user', ( req, res, next ) => {
  User.findAll()
    .then( userResponse => {
      res.status( 200 ).json( userResponse )
    } )
    .catch( error => {
      res.status( 400 ).send( error )
    } )
} )

module.exports = router

TypeError：User.FindAll不是router.Get(D:\stateboard-project\v2\components\user\usercomponent.js:6:8)在Layer.Handle[as handle_request](D:\stateboard-project\v2\node_module\express\lib\router\layer.js:95:5)在next(D:\stateboard-project\v2\node_module\express\lib\router\route.js:137:13)在

下面是由Sequelize自动生成的model/index.js文件。

const fs        = require( 'fs' )
const path      = require( 'path' )
const Sequelize = require( 'sequelize' )
const basename  = path.basename( module.filename )
const env       = process.env.NODE_ENV || 'development'
const config    = require( __dirname + '/..\database.html" target="_blank">json' )[env]
const db        = {}

let sequelize
if (config.use_env_variable) {
  sequelize = new Sequelize( process.env[ config.use_env_variable ] )
} else {
  sequelize = new Sequelize( config.database, config.username, config.password, config )
}

fs
  .readdirSync( __dirname )
  .filter( function( file ) {
    return ( file.indexOf( '.' ) !== 0 ) && ( file !== basename ) && ( file.slice( -3 ) === '.js' )
  } )
  .forEach( function( file ) {
    var model = sequelize[ 'import' ]( path.join( __dirname, file ) )
    db[ model.name ] = model
  });

Object.keys( db ).forEach( function( modelName ) {
  if ( db[ modelName ].associate ) {
    db[ modelName ].associate( db )
  }
});

db.sequelize = sequelize
db.Sequelize = Sequelize

module.exports = db

这里缺什么？

您应该需要models/index.js来使用models，而不是models/user.js。

const models = require( '../../models/index');

router.get( '/user', ( req, res, next ) => {
  models.User.findAll()
    .then( userResponse => {
      res.status( 200 ).json( userResponse )
    })
    .catch( error => {
      res.status( 400 ).send( error )
    })
} )
