如何測試值是否存在於Ramda對象集

Question

我想知道如何查看一個特定的值，在這種情況下「/ db/User/10」是否存在於一組對象中從API返回。

將數據從API返回的執行console.log（測試）

Set { 
    Object { 
    "UserData": "/db/UserData/509c404f-ffa1-49d3-a161-b9eb5b2ebb14", 
    "UserDataPrivate": "/db/UserDataPrivate/26b7d879-4403-4135-ab44-b23e5244606b", 
    "UserStatus": "/db/UserStatus/cb50eae0-e254-4d8c-915a-674fd314fff3", 
    "createdAt": "2017-10-20T21:03:26.575Z", 
    "id": "/db/User/68", 
    "inactive": null, 
    "updatedAt": "2017-10-20T23:34:12.179Z", 
    "username": "15031111234", 
    "version": 4, 
    }, 
    Object { 
    "UserData": "/db/UserData/a3dded63-4e0b-4841-b201-4c96dad1844d", 
    "UserDataPrivate": "/db/UserDataPrivate/6037a718-e33f-4945-b2d0-ca4c11fa4f13", 
    "UserStatus": null, 
    "createdAt": "2017-09-21T18:26:31.089Z", 
    "id": "/db/User/10", 
    "inactive": false, 
    "updatedAt": "2017-10-18T20:10:06.681Z", 
    "username": "15038304313", 
    "version": 19, 
    }, 
} 

var searchbyID = propEq('id', '/db/User/10'); 
result = filter(searchbyID, test); 
console.log(result) 

我想這應該返回true，而是，它返回一個空數組。

這是拉姆達的正確方法嗎？

Answer 1

您需要將Set轉換爲數組。

var searchbyID = propEq('id', '/db/User/10'); 
result = filter(searchbyID, Array.from(test)); 
console.log(result) 

它不會返回true，而是匹配的對象。您可能需要改爲find。
