javascript - 用es6写书架模型

Question

有什么方法可以使用 es6 类来编写书架模型吗？我可以看到书架源代码本身是用 es6 编写的。但是我遇到的所有示例和资源都是用 es5 编写的。我看到一个精心制作的github issue在此声明这是可能的，但它主要讨论了关于在类中编写模型的一些错误。如何使用 es6 类编写和使用书架模型？

是的，你可以!

// database.js
import config from '../../knexfile';
import knex from 'knex';
import bookshelf from 'bookshelf';

const Bookshelf = bookshelf(knex(config[process.env.NODE_ENV || 'development']));

Bookshelf.plugin('registry'); // Resolve circular dependencies with relations
Bookshelf.plugin('visibility');

export default Bookshelf;


// Administers.js
import Bookshelf from '../database'
import { createValidatorPromise as createValidator, required, email as isEmail } from '../../utils/validation';
import { User, Organization } from '../';
import { BasicAdministersView, DetailedAdministersView } from '../../views/index';

class Administers extends Bookshelf.Model {

  get tableName() { return 'administers'; }

  get hasTimestamps() { return true; }

  view(name){
    return new ({
      basic: BasicAdministersView,
      detailed: DetailedAdministersView
    }[name])(this);
  }

  user() {
    console.log(User);
    return this.belongsTo('User', 'user_id');
  }

  organization() {
    return this.belongsTo('Organization', 'organization_id');
  }
}

export default Bookshelf.model('Administers', Administers);
