Question

我在“字段列表”中收到“未知”列错误尝试创建实例db.Partner.create时。

代码正在运行，但不知何故它停止了（在我输入用户模型和一些中间件之后）

这是我收到的错误：

C:\Users\User\code\project\node_modules\mysql\lib\protocol\Parser.js:79
        throw err; // Rethrow non-MySQL errors
        ^

这是我的控制器：

var db = require('../models');

module.exports.addPartner = function(req_title, req_img){
    var partner = db.Partner.create({
        title: req_title,
        img: req_img
    });
}

我的模特：

"use strict";

module.exports = function(sequelize, DataTypes) {

    var Partner = sequelize.define('Partner', {
        id: {
          type: DataTypes.INTEGER(12),
          allowNull: false,
          primaryKey: true,
          autoIncrement: true
        },
        title: {
          type: DataTypes.STRING,
          allowNull: false
        },
        img: {
          type: DataTypes.STRING,
          allowNull: false,
          set: function(val) {
            return this.setDataValue('img', val.toLowerCase());
          }
        }
      }, {
        tableName: 'partner',
        createdAt: 'created_at',
        updatedAt: false
      });

    return Partner;
};

模型文件夹中的index.js：

var fs = require('fs');
var path = require('path');
var config = require('../../config/mysql');
var Sequelize = require('sequelize');
var lodash = require('lodash');
var db = {};

// mysql connect
var sequelize = new Sequelize(
  config.database,
  config.user,
  config.password, 
  {
    host: config.host,
    port: config.port,
    logging: false,
    dialect: 'mysql'
  }
 );

fs.readdirSync(__dirname)
  .filter(file => (file.indexOf('.') !== 0 && file !== 'index.js'))
  .forEach(file => {
    const model = sequelize.import(path.join(__dirname, file));
    db[model.name] = model
  });

Object.keys(db).forEach(modelName => {
  if (db[modelName].options.hasOwnProperty('associate')) {
    db[modelName].options.associate(db)
  }
});

module.exports = lodash.extend({
  sequelize,
  Sequelize
}, db);

NodeJS在“字段列表”
