mysql - Feathers sequelize 按关联列查找

Question

我正在尝试根据关联表的值过滤数据，当我查找全部时它工作正常但是当我尝试按名称搜索时，我得到一个列不存在错误
我已经设置了一个钩子(Hook)，如 https://github.com/feathersjs-ecosystem/feathers-sequelize#associations 中所述
在 postman 中，我可以将关联视为子键，但我无法按任何列搜索
获取代码

service.find({
        query: {
          include: ["policyholders"],
          Name: {
            $like: `%somename%`,
          },
        },
      });

政策模型

// See http://docs.sequelizejs.com/en/latest/docs/models-definition/
// for more of what you can do here.
const Sequelize = require("sequelize");
const DataTypes = Sequelize.DataTypes;

module.exports = function (app) {
  const sequelizeClient = app.get("sequelizeClient");
  const policies = sequelizeClient.define(
    "policies",
    {
      PolicyId: {
        autoIncrement: true,
        type: DataTypes.INTEGER,
        allowNull: false,
        primaryKey: true,
      },
      PolicyNumber: {
        type: DataTypes.STRING(30),
        allowNull: true,
      },
      PolicyHolderId: {
        type: DataTypes.INTEGER,
        allowNull: true
      },
    },
    {
      hooks: {
        beforeCount(options) {
          options.raw = true;
        },
      },
    }
  );

  // eslint-disable-next-line no-unused-vars
  policies.associate = function (models) {
    // Define associations here
    // See http://docs.sequelizejs.com/en/latest/docs/associations/
    const { policyholders } = models;
    policies.belongsTo(policyholders, { foreignKey: "PolicyholderId" });
  };

  return policies;

const Sequelize = require('sequelize');

政策 Hook

const { authenticate } = require('@feathersjs/authentication').hooks;

const getRelated = require('../../hooks/get-related');

module.exports = {
  before: {
    all: [ authenticate('jwt') ],
    find: [getRelated()],
    get: [getRelated()],
    create: [],
    update: [],
    patch: [],
    remove: []
  },

  after: {
    all: [],
    find: [],
    get: [],
    create: [],
    update: [],
    patch: [],
    remove: []
  },

  error: {
    all: [],
    find: [],
    get: [],
    create: [],
    update: [],
    patch: [],
    remove: []
  }
};

钩子(Hook)相关

module.exports = function (options = {}) {
  return async (context) => {
    const { include, ...query } = context.params.query;

    if (include) {


      const AssociatedModel = context.app.services.policyholders.Model;
      context.params.sequelize = {
        include: [{ model: AssociatedModel }],
        raw: false
      };

      
      // Update the query to not include `include`
      context.params.query = query;
    }

    return context;
  };
};

Answer 1

答案也是

 "$policyholder.Name%": {
            $like: `%somename%`,
          },

然后在羽毛服务中将字符串添加到白名单数组
