使用clojure monger用joda.time.datetime查询mongo

Question

我在尝试用{$lte start $gte end}查询obj时得到了这个错误代码，你能给我看一些用coda.datetime查询的示例吗？

IllegalArgumentException can't serialize class org.joda.time.DateTime org.bson.BasicBSONEncoder._putObjectField (BasicBSONEncoder.java:284)

功能：

(defn data->orders [start end]
  (let [db (mg/get-db conn/mongo-db "db")
        coll "coll"
        formatter (f/formatter "YYYY-MM-dd")]
    (mc/find-maps db coll
                  {:created_at
                   {$gte (f/parse formatter start)
                    $lte (f/parse formatter end)}})))

添加到ns

(:require monger.joda-time)
