如何使用 sequelize 對包含表的 jsonb 列應用 where 子句？

Question

我在 postgres 數據庫中有 2 個表。

Table_A
--------
id BIGINT
metadata JSONB

Table_B
--------
id BIGINT
a_id BIGINT
metadata JSONB

我正在使用 sequelize 並嘗試將 where cluse 應用於包含表的 jsonb 列。

例子：

let query = {
        where: {
            '$table_b.metadata.address$': 'Banglore'
        }
        include: [
            {
                model: Table_B,
                as: 'table_b'
            }
        ]
    };
    
Table_A.findAndCountAll(query).then((result)=>{
    console.log(JSON.stringify(result.rows));
}).catch((err)=>{
    console.log(err)
})

但我得到以下錯誤

original: error: missing FROM-clause entry for table "table_b->metadata"
  at Parser.parseErrorMessage (C:\Project\test\FilterTest\node_modules\pg-protocol\dist\parser.js:287:98)
  at Parser.handlePacket (C:\Project\test\FilterTest\node_modules\pg-protocol\dist\parser.js:126:29)

  at Socket.Readable.push (internal/streams/readable.js:206:10)
  at TCP.onStreamRead (internal/stream_base_commons.js:188:23) {

誰能幫助如何為包含表的 jsonb 列應用 where 子句？

試試這個方法。

const query = {
    include: [{
        model: Table_B,
        as: 'table_b',
        where: {
            metadata: {
                address: 'Banglore'
            }
        }
    }]
};
