我的rethinkdb中有一堆文件看起来像这样。

每个文档都包含几个“blob”。我需要查询所有文档中的所有blob并返回与指纹匹配的“blob”。我正在努力弄清楚这应该是什么样的。

我尝试了此查询但返回了所有文档。

r.db('db').table('data').filter(r.row('blobs').contains(function(product) {
return product('fingerprint').eq('742c3192e607e424eb4549542be1bbc53e6174e2');
}))

Answer 1

这样做你想要的吗？

table.concatMap(function(row) { return row('blobs'); }).filter(function(blob) {
  return blob('fingerprint').eq('742c3192e607e424eb4549542be1bbc53e6174e2');
})

在数组中查询
