Question

我在我的服务器上使用feathersjs（带有websockets）和sequelize并升级到Buzzard版本。这个钩子在我的服务器上，用于在升级之前正常工作： ```

module.exports = function (options = {}) { 
  return function (hook) {
    if (hook.params.query && hook.params.query.include) {
      const joinModel = hook.app.service('favorites_points').Model;
      const pointsModel = hook.app.service('points').Model;
      hook.params.sequelize = {
        raw: false,
        include: [{
          model: joinModel,
          as: 'FavPoints',
          include: [{
            model: pointsModel
          }]
        }]
      };
      delete hook.params.query.include;
    }
    return Promise.resolve(hook);
  };
};

升级后，从客户端调用时： api.service('users').get(2, {query: {include: true}})

我收到此错误（顺便说一句：当我遗漏内部include: [{ model: pointsModel }]时，仍然存在同样的错误）：

当我评论raw: false,时，它会给出正确的输出。我查了一下，但在我的'升级前版本'中，当我离开raw: false,时，查询也会起作用，但是当它添加时输出结构是不同的（更嵌套），所以让我觉得sequelize被简单地绕过了可能没有急切加载等等所以我想使用raw: false,

升级服务器的Package.json后：

"@feathersjs/authentication": "^2.1.0",
"@feathersjs/authentication-jwt": "^1.0.1",
"@feathersjs/authentication-local": "^1.0.2",
"@feathersjs/authentication-oauth2": "^1.0.2",
"@feathersjs/configuration": "^1.0.1",
"@feathersjs/errors": "^3.2.0",
"@feathersjs/express": "^1.1.2",
"@feathersjs/feathers": "https://github.com/feathersjs/feathers.git#master",
"@feathersjs/socketio": "^3.0.1",
"feathers-authentication-hooks": "^0.1.5",
"feathers-hooks-common": "git://github.com/feathers-plus/feathers-hooks-common.git#master",
"feathers-sequelize": "^3.0.0",
"sequelize": "^4.28.6",

在服务器上升级Package.json之前：

"feathers": "^2.2.3",
"feathers-authentication": "^1.3.0",
"feathers-authentication-hooks": "^0.1.5",
"feathers-authentication-jwt": "^0.3.2",
"feathers-authentication-local": "^0.4.4",
"feathers-authentication-oauth2": "^0.3.2",
"feathers-blob": "^1.3.1",
"feathers-configuration": "^0.4.2",
"feathers-errors": "^2.9.2",
"feathers-hooks": "^2.1.2",
"feathers-hooks-common": "^3.10.0",
"feathers-rest": "^1.8.1",
"feathers-seeder": "^1.0.10",
"feathers-sequelize": "^2.4.0",
"feathers-socketio": "^2.0.1",
"sequelize": "^4.23.1",

我的问题：为什么它不再适用于raw: false,，我该如何解决？

Answer 1

添加dehydrate hook（作为后挂钩）后，输出符合预期。我不清楚为什么在升级之前这不是问题。

升级到Buzzard之后，羽毛-sequelize不再与```raw：false```一起使用
