javascript - sails js 中的模型关联

Question

我想在 SAILS.JS 中创建一个模型与另外两个模型的模型关联。但是编译时出现错误。

这个模型是User.js

module.exports = {

  attributes: {
    email: {
      type: 'string',
      required: true,
      unique: true
    },
    password: {
      type: 'string',
      required: true,
    },
    google: {
        model:'Google'
    },
      facebook: {
        model:'Facebook'
    }
  }
};

这个模型是Google.js

module.exports = {

  attributes: {
      kind: 'string',
      gender: 'string',
      sub: 'string',
      name: 'string',
      given_name: 'string',
      family_name: 'string',
      profile: 'string',
      picture: 'string',
      email: 'string',
      email_verified: 'string',
      locale: 'string',
      user:{
        model:'User'
      }
  }
};

这个模型是 Facebook.js

module.exports = {

  attributes: {
      name: 'string', 
      id: 'string', 
      user:{
          model:'User'
      }
  }
};

我得到以下错误

/usr/lib/node_modules/sails/node_modules/waterline/node_modules/waterline-schema/lib/waterline-schema/foreignKeys.js:104
    throw new Error(error);
          ^

Answer 1

好吧，在发布问题 2 分钟后，我看到了问题所在。我在 facebook 模型中使用了一个 id 属性，这是一个主键属性。 http://sailsjs.org/documentation/concepts/models-and-orm/attributes

因此错误。已解决。
