如何在graphQl/Sequelize中将where子句应用于嵌套查询？

const { GraphQLObjectType, GraphQLString, GraphQLList } = require('graphql');
const { User, Post } = require('./models'); // 假设有User和Post两个模型

const UserType = new GraphQLObjectType({
  name: 'User',
  fields: () => ({
    id: { type: GraphQLString },
    name: { type: GraphQLString },
    posts: {
      type: new GraphQLList(PostType),
      resolve: (user) => {
        return user.getPosts({ where: { status: 'published' } }); // 应用WHERE子句
      }
    }
  })
});

const PostType = new GraphQLObjectType({
  name: 'Post',
  fields: () => ({
    id: { type: GraphQLString },
    title: { type: GraphQLString },
    content: { type: GraphQLString },
    user: {
      type: UserType,
      resolve: (post) => {
        return post.getUser();
      }
    }
  })
});

// 定义根查询类型
const RootQueryType = new GraphQLObjectType({
  name: 'RootQuery',
  fields: {
    user: {
      type: UserType,
      args: {
        id: { type: GraphQLString }
      },
      resolve: (_, args) => {
        return User.findByPk(args.id);
      }
    }
  }
});

// 定义GraphQL模式
const schema = new GraphQLSchema({
  query: RootQueryType
});
