我在從數據庫中提取數據時遇到問題。我在mongodb數據庫中有一個數組類型列,其中我保存了每個數組索引中的哈希類型數據。我必須根據數據庫中的散列匹配來獲取數據。查詢在mongoDB中包含散列的數組字段?
我在數據庫中的數據被保存這樣
{
"_id" : ObjectId("521603970ff5fa4b47000018"),
"message_text" : "#cricket #badminton #sachin #tendulkar #ibl #masterblaster #srt Cricketing world lights up IBL http://t.co/RWskRM2EQf via @msncricket",
"source" : "<a href=\"http://twitter.com/tweetbutton\" rel=\"nofollow\">Tweet Button</a>",
"status_id" : NumberLong("370521615638884352"),
"status_created_at" : "2013-08-22 17:53:31 +0530",
"user_id" : "31677680",
"screen_name" : "msncricket",
"name" : "MSN Cricket",
"followers_count" : 11515,
"friends_count" : 303,
"query" : [
{
"filterId" : "5215b40c0ff5fa111e000001",
"subfilterId" : "60728003610375795",
"type" : "keyword",
"source" : "twitter",
"monitoring_type" : false,
"search_type" : false,
"searchParameter" : "sachin",
"geo" : "india",
"language" : "en"
}
]
}
查詢列是陣列類型列。
在尋找我做一個哈希再次形成匹配它像如下
query = {"filterId"=>"5215b40c0ff5fa111e000001", "subfilterId"=>"60728003610375795", "type"=>"keyword", "source"=>"twitter", "monitoring_type"=>false, "search_type" => false, "searchParameter"=>"sachin", "geo"=>"india", "language"=>"en"}
@result = Statuses.where({query: query})
我該如何在rails中運行查詢活動記錄 –
我不使用ruby。對不起:(但現在你可以肯定谷歌如何做elemMatch在你的紅寶石mongo使用什麼樣的ODM或包裝。:) –
其在mongodb控制檯也工作 –
