如何在mongoid模型中保存數組的數組？

Question

我有一個api的響應，我需要保存在我的模型中使用mongoid。

我相信響應是一個數組的數組，我似乎不能將它保存爲數組或散列。這是一個響應的例子。有誰知道我可以用mongoid保存這個文件嗎？

響應...

=> #<Tipper::User:0xb600c10 @accounts=[#<Tipper::Account:0xb5b8618 @id="QPO8Jo8vdDHMepg41PBwckXm4KdK1yUdmXOwK", @name=nil, @type="depository", @meta={"number"=>"9606", "name"=>"Tipper Savings"}, @institution_type="fake_institution", @available_balance=1203.42, @current_balance=1274.93, @subtype=nil, etc... 

什麼辦法可以挽救這使我的應用程序可以參考呢？

我試圖使它使用這種方法的陣列...

def transactions 
    response = Tipper.set_user(access_token, ['auth']) 
    self.transactions = response.as_json 
    save 
    end 

它仍然不會工作

在JSON的反應是這樣的......

=> {"accounts"=>[{"id"=>"QPO8Jo8vdDHMepg41PBwckXm4KdK1yUdmXOwK", "name"=>nil, "type"=>"depository", "meta"=>{"number"=>"9606", "name"=>"Tipper Savings"}, "institution_type"=>"fake_institution",

我模型字段看起來像這樣

Transaction.rb 
    class Transaction 
    include Mongoid::Document 

field :transactions, type: Array 

    def transactions 
    response = Tipper.set_user(access_token, ['auth']) 
    self.transactions = response.as_json 
    save 
    end 
end

你需要建立在一個蒙戈和Collection然後看看你的API響應，並決定要如何保存數據。它看起來像打印出某種類型的HTTP響應對象。你不能把它扔到數據庫中。如果HTTP響應包含JSON（例如），那麼您需要將其轉換爲數組。然後，將其指定爲您的Collection上一個新的Document數組屬性。
