【问题描述】:
我的数据库看起来像
{
"chats" : {
"-K5hUtxNOPLWwRTb8fAj" : {
"clientId" : 893,
"messages" : {
"-K5hUtyCwWuPeFT0cSXr" : {
"chatKey" : "-K5hUtxNOPLWwRTb8fAj",
"messageText" : "new message",
"timestamp" : 1450314801055,
"userId" : "19eaa3f0-4ab3-44b4-b418-03b64ca2313a"
},
"-K5hUvwKsAOvuvt-ymFG" : {
"chatKey" : "-K5hUtxNOPLWwRTb8fAj",
"messageText" : "did this work",
"timestamp" : 1450314809127,
"userId" : "48f7a208-5647-4d0e-921c-c49595de1db2"
}
},
"newQuestion" : false,
"startedByUserId" : "19eaa3f0-4ab3-44b4-b418-03b64ca2313a"
},
"-K5hVKjs4SkSHD7WTh1I" : {
"clientId" : 518,
"messages" : {
"-K5hVNzPKNgxLCgkfInI" : {
"chatKey" : "-K5hVKjs4SkSHD7WTh1I",
"messageText" : "this is new",
"timestamp" : 1450314928109,
"userId" : "19eaa3f0-4ab3-44b4-b418-03b64ca2313a"
}
},
"newQuestion" : true,
"startedByUserId" : "19eaa3f0-4ab3-44b4-b418-03b64ca2313a"
}
}
}
如何获取所有将newQuestion 设置为true 的chats?我尝试了几个不同的查询,最新的是:
firebaseDb.child("chats/newQuestion").equalTo(true).once("value"...
但这抱怨布尔值需要订单?
