FeathersJS auk服务器填充钩子不工作

Question

我试图使用新的人口挂钩，但它似乎不起作用。我只是不知道我做错了什么。

我有一个与merchatTypeMap商人模型相关的1:1的模型，当我查询这个模型时，它应该使用附加的相关商人来回答。

merchantTypeMap服务：

'use strict';

const service = require('feathers-sequelize');
const merchantTypeMap = require('./merchantTypeMap-model');
const hooks = require('./hooks');

module.exports = function(){
  const app = this;

  const options = {
    Model: merchantTypeMap(app.get('sequelize')),
    paginate: {
      default: 5,
      max: 25
    }
  };

  // Initialize our service with any options it requires
  app.use('/merchantTypeMaps', service(options));

  // Get our initialize service to that we can bind hooks
  const merchantTypeMapService = app.service('/merchantTypeMaps');

  // Set up our before hooks
  merchantTypeMapService.before(hooks.before);

  // Set up our after hooks
  merchantTypeMapService.after(hooks.after);
};

这是我的merchantTypeMap模型代码：

'use strict';

// merchantTypeMap-model.js - A sequelize model
// 
// See http://docs.sequelizejs.com/en/latest/docs/models-definition/
// for more of what you can do here.

const Sequelize = require('sequelize');

module.exports = function(sequelize) {
  const merchantTypeMap = sequelize.define('merchantTypeMaps', {
    id: {
      type: Sequelize.INTEGER(10),
      allowNull: false,
      primaryKey: true,
      autoIncrement: true,
      field: 'id'
    },
    merchantId: {
      type: Sequelize.INTEGER(10),
      allowNull: true,
      references: {
        model: 'merchants',
        key: 'id'
      },
      field: 'merchant_id'
    },
    merchantTypeId: {
      type: Sequelize.INTEGER(10),
      allowNull: true,
      references: {
        model: 'merchantTypes',
        key: 'id'
      },
      field: 'merchantType_id'
    }
  }, {
    freezeTableName: true
  });

  merchantTypeMap.belongsTo(sequelize.models.merchants, {foreignKey: 'merchant_id'});

  merchantTypeMap.sync();

  return merchantTypeMap;
};

在这里，我的merchantTypeMap服务挂钩：

'use strict';

const globalHooks = require('../../../hooks');
const hooks = require('feathers-hooks-common');

const schema = {
  include: [{
    service: 'merchants',
    nameAs: 'merchantItem',
    parentField: 'merchantId',
    childField: 'id',
  }]
};

exports.before = {
  all: [],
  find: [],
  get: [],
  create: [],
  update: [],
  patch: [],
  remove: []
};

exports.after = {
  all: [],
  find: [
    hooks.populate( { schema } )
  ],
  get: [
    hooks.populate( { schema } )
  ],
  create: [],
  update: [],
  patch: [],
  remove: []
};

The 服务：

'use strict';

const service = require('feathers-sequelize');
const merchantTypeMap = require('./merchantTypeMap-model');
const merchants = require('./merchants-model');
const hooks = require('./hooks');

module.exports = function(){
  const app = this;

  merchantTypeMap(app.get('sequelize'));

  const options = {
    Model: merchants(app.get('sequelize')),
    paginate: {
      default: 5,
      max: 25
    }
  };

  // Initialize our service with any options it requires
  app.use('/merchants', service(options));

  // Get our initialize service to that we can bind hooks
  const merchantsService = app.service('/merchants');

  // Set up our before hooks
  merchantsService.before(hooks.before);

  // Set up our after hooks
  merchantsService.after(hooks.after);
};

商人模型：

“严格使用”；

// merchants-model.js - A sequelize model
// 
// See http://docs.sequelizejs.com/en/latest/docs/models-definition/
// for more of what you can do here.

const Sequelize = require('sequelize');

module.exports = function(sequelize) {
  const merchants = sequelize.define('merchants', {
    id: {
      type: Sequelize.INTEGER(10),
      allowNull: false,
      primaryKey: true,
      autoIncrement: true,
      field: 'id'
    },
    title: {
      type: Sequelize.STRING,
      allowNull: true,
      field: 'title'
    },
    latitude: {
      type: Sequelize.STRING,
      allowNull: true,
      field: 'latitude'
    },
    longitude: {
      type: Sequelize.STRING,
      allowNull: true,
      field: 'latitude'
    },
    address: {
      type: Sequelize.STRING,
      allowNull: true,
      field: 'address'
    },
    icon: {
      type: Sequelize.STRING,
      allowNull: true,
      field: 'icon'
    },
    zoneId: {
      type: Sequelize.INTEGER(10),
      allowNull: true,
      references: {
        model: 'zones',
        key: 'id'
      },
      field: 'zone_id'
    }
  }, {
    freezeTableName: true
  });

  merchants.belongsToMany(sequelize.models.merchantTypes, {through: sequelize.models.merchantTypeMaps});

  merchants.sync();

  return merchants;
};

您需要配置Sequelize来返回普通JS对象，而不是它的ORM对象，方法是使用raw: true选项。

顺便说一句，钩子v3很快就会发布。所有钩子，包括填充，然后将自动转换Sequelize和Mongoose为普通JS对象。对某些人来说，这可能是一个破缺。

编辑来自ORM对象的转换可能是在羽毛服务中完成的，而不是通过钩子完成的。这样，问题就不会出现在人们所写的自定义钩子中。
