GraphQL查询

早上好

我有一个很好的设置GraphQL->Sequalize->existingdb（由一个Laravel应用程序生成）。我构建了这个模式：

  type App {
    id: ID!
    userId: ID
    user: User
    pages: [Page]
    experiments: [Experiment]
    uri: String!
    createdAt: String!
    updatedAt: String!
  }
  type Page {
    id: ID!
    userId: ID
    user: User
    appId: ID!
    app: App!
    uri: String!
    createdAt: String!
    updatedAt: String!
  }
  type Experiment {
    id: ID!
    title: String!
    appId: ID!
    app: App!
    createdAt: String!
    updatedAt: String!
  }

基于现有数据。查询应用程序实验非常有效：

query {
  app(id: 6) {
    id
    title
    experiments {
      id
    }
  }
}

但我得到的是：

query {
  app(id: 6) {
    id
    title
    pages {
      id
    }
  }
}

db列与解析程序相同：

/* jshint indent: 2 */

module.exports = function(sequelize, DataTypes) {
  const Page = sequelize.define(
    "page",
    {
      id: {
        type: DataTypes.INTEGER(10).UNSIGNED,
        allowNull: false,
        primaryKey: true,
        autoIncrement: true
      },
    ...
      createdAt: {
        type: DataTypes.DATE,
        allowNull: true
      },
      updatedAt: {
        type: DataTypes.DATE,
        allowNull: true
      }
    },
    {
      tableName: "pages",
      underscored: true
    }
  );

  Page.associate = models => {
    Page.belongsTo(models.app);
  };
  return Page;
};

您以前遇到过这个问题吗？

您能为应用程序和页面提供完整的graphql定义吗。@iAmADeveloper已更新，以包含完整的架构。
