ruby - ruby将哈希插入mongodb，得到未定义的方法`has_key？

Question

我正在尝试使用 ruby​​ mongo 驱动程序将哈希插入 mongodb。我明白了undefined method has_key? error

下面是代码

require 'rubygems'
require 'mongo'

include Mongo
@client = MongoClient.new('localhost', 27017)
@db     = @client['sample-db']
@coll   = @db['test1']

@coll.remove
puts abc
#value of abc hash is  {:command=>"runlocal", :remotecommand=>"rm process_2013-04-25.log"}

@coll.insert("#{abc}")

输出应该看起来像

 { "_id" : ObjectId("5174c4aeb2441139ec000001"), "command" : "runlocal", "remotecommand" : "rm......" }

查看论坛后，我找到了如下解决方案。但我不想更改架构。

id = @coll.insert({:status =>"#{abc}"})

哪个生产

 { "_id" : ObjectId("517b69d2b2441136b8000001"), "status" : "{'command' => "runlocal"....

更新：解决方案

 id = @coll.insert({"#{abc}"})

根据需要产生以下输出

 {"_id"=>BSON::ObjectId('517bfc79b244110a08000001'), "command" : "runlocal", "remotecommand" : "rm process_2013-04-25.log"}
