Node/Express中的Sequelize - '没有这样的表:main.User`错误

Question

我正在尝试使用Sequelize构建一个简单的Node/Express应用程序,但是当我尝试在我的关系数据库中创建一个新记录时,我收到错误Unhandled rejection SequelizeDatabaseError: SQLITE_ERROR: no such table: main.User.基本上,我在Users表中创建一个用户,然后尝试在表中创建一个相关的地址Addresses- 用户已成功创建但在创建地址时失败并出现此错误...其中是main从表名中获取前缀？(下面的完整错误读数)...

首先,这是我的计划的简要介绍......

• 我的Sequelize版本是Sequelize [Node: 6.8.1, CLI: 2.4.0, ORM: 3.29.0],我使用Sequelize CLI命令sequelize init来设置我项目的这一部分.

• 我使用SQLite3进行本地开发,并且config/config.json我将开发数据库定义为

  "development": {
      "storage": "dev.sqlite",
      "dialect": "sqlite"
  }
  

• 我的用户迁移:

  'use strict';
      module.exports = {
          up: function(queryInterface, Sequelize) {
              return queryInterface.createTable('Users', {
                  id: {
                      allowNull: false,
                      autoIncrement: true,
                      primaryKey: true,
                      type: Sequelize.INTEGER
                  },
                  first_name: {
                      type: Sequelize.STRING
                  },
                  last_name: {
                      type: Sequelize.STRING
                  },
                  createdAt: {
                      allowNull: false,
                      type: Sequelize.DATE
                  },
                  updatedAt: {
                      allowNull: false,
                      type: Sequelize.DATE
                  }
              });
          },
          down: function(queryInterface, Sequelize) {
              return queryInterface.dropTable('Users');
          }
      };
  

• 和地址迁移(缩写):

  module.exports = {
      up: function(queryInterface, Sequelize) {
          return queryInterface.createTable('Addresses', {
              id: {
                  allowNull: false,
                  autoIncrement: true,
                  primaryKey: true,
                  type: Sequelize.INTEGER
              },
              address_line_one: {
                  type: Sequelize.STRING
              },
              UserId: {
                  type: Sequelize.INTEGER,
                  allowNull: false,
                  references: {
                      model: "User",
                      key: "id"
                  }
              }
          })
      }
  

• 用户模型:

  'use strict';
  module.exports = function(sequelize, DataTypes) {
      var User = sequelize.define('User', {
          first_name: DataTypes.STRING,
          last_name: DataTypes.STRING
      }, {
     classMethods: {
         associate: function(models) {
             models.User.hasOne(models.Address);
         }
      }
   });
  return User;
  };
  

• 和地址模型:

  'use strict';
  module.exports = function(sequelize, DataTypes) {
      var Address = sequelize.define('Address', {
          address_line_one: DataTypes.STRING,
          UserId: DataTypes.INTEGER
      }, {
          classMethods: {
              associate: function(models) {
                  models.Address.hasOne(models.Geometry);
                  models.Address.belongsTo(models.User, {
                      onDelete: "CASCADE",
                      foreignKey: {
                          allowNull: false
                      }
                  });
              }
            }
        });
   return Address;
   };
  

• 最后,我的路线index.js:

  router.post('/createUser', function(req, res){
      var firstName = req.body.first_name;
      var lastName = req.body.last_name;
      var addressLineOne = req.body.address_line_one;
  
      models.User.create({
          'first_name': newUser.firstName,
          'last_name': newUser.lastName
      }).then(function(user){         
          return user.createAddress({
              'address_line_one': newUser.addressLineOne
      })
  })
  

因此,当我尝试发布时/createUser,将成功创建用户并且控制台将说明已创建新地址(INSERT INTO 'Addresses'...),但未创建地址并记录以下错误:

Unhandled rejection SequelizeDatabaseError: SQLITE_ERROR: no such table: main.User at Query.formatError (/Users/darrenklein/Desktop/Darren/NYCDA/WDI/projects/world_table/wt_test_app_1/node_modules/sequelize/lib/dialects/sqlite/query.js:348:14) at afterExecute (/Users/darrenklein/Desktop/Darren/NYCDA/WDI/projects/world_table/wt_test_app_1/node_modules/sequelize/lib/dialects/sqlite/query.js:112:29) at Statement.errBack (/Users/darrenklein/Desktop/Darren/NYCDA/WDI/projects/world_table/wt_test_app_1/node_modules/sqlite3/lib/sqlite3.js:16:21)

几个月前我曾经和Sequelize做过一次这样的事情并且成功了,我不能为我的生活找出我在这里缺少的东西.应用程序为什么要查找main.User,如何才能找到正确的表格？谢谢!

啊哈!一个小错误使我的整个操作脱轨.在迁移文件中,references.model必须是多元化的!

references: {
    model: "Users",
    key: "id"
}

繁荣.
