在 Sequelize 模型钩子函数中访问其他模型 [英] Accessing other models in a Sequelize model hook function

问题描述

我正在尝试创建一个模型挂钩，该挂钩在创建主模型时自动创建关联记录.当我的模型文件结构如下时，如何在钩子函数中访问我的其他模型?

I'm trying to create a model hook that automatically creates an associated record when the main model has been created. How can I access my other models within the hook function when my model file is structured as follows?

/**
 * Main Model
 */
module.exports = function(sequelize, DataTypes) {

  var MainModel = sequelize.define('MainModel', {

    name: {
      type: DataTypes.STRING,
    }

  }, {

    classMethods: {
      associate: function(models) {

        MainModel.hasOne(models.OtherModel, {
          onDelete: 'cascade', hooks: true
        });

      }
    },

    hooks: {

      afterCreate: function(mainModel, next) {
        // ------------------------------------
        // How can I get to OtherModel here?
        // ------------------------------------
      }

    }

  });


  return MainModel;
};

推荐答案

可以通过sequelize.models.OtherModel访问其他模型.

You can access the other model through sequelize.models.OtherModel.
