mongodb - 使用 clojure-monger 使用 joda.time.datetime 查询 mongo

Question

尝试使用查询 obj 时收到此错误代码{$lte start $gte end}，您能告诉我一些使用 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)}})))
