我是mongodb的新手。在门户网站上工作我想实现一个嵌套的搜索。我的数据如下：
$query = $mongoDb->find(array('City' => $city, 'SubjectValuation.Subject' => $subject, 'SubjectValuation.Primary' => $level));
我跑的查询是：
$subject当我通过数学＆＃39;在public object BindModel(ControllerContext controllerContext, System.Web.Mvc.ModelBindingContext bindingContext)
{
string type = controllerContext.HttpContext.Request.Form["ModelName"];
if (type == null)
{
throw new MissingFieldException("ModelName wasn't found");
}
type = type.Substring(type.LastIndexOf('.') + 1);
HttpRequestBase request = controllerContext.HttpContext.Request;
switch (type)
{
case "MissingDeliveryNoteNumberModel":
MissingDeliveryNoteNumberModel mdnnModel = new MissingDeliveryNoteNumberModel(request);
return mdnnModel;
case "MissingCardBoxModel":
MissingCardBoxModel mcbModel = new MissingCardBoxModel(request);
return mcbModel;
case "WrongItemsReceivedModel":
WrongItemsReceivedModel wirModel = new WrongItemsReceivedModel(request);
return wirModel;
default:
return null;
}
}
我得到了一个结果，但是当我通过英语＆＃39;然后没有记录被检索。如何为这种数组实现嵌套搜索？
答案 0 :(得分：0)
试试这个没有经过测试但在逻辑上它可以工作 $ query = $ mongoDb-＆gt; find（array（'City'=＆gt; $ city，'$ and'=＆gt; ['SubjectValuation.Subject'=＆gt; $ subject，'SubjectValuation.Primary'=＆gt; $ level ]））;
