Question

我有一个允许用户搜索的Ruby应用程序。我正在构建一个数据存储表，用于保存站点上发生的每个搜索。在创作中，我传递了一些东西：

ID of returned object controller action Search term ip address of user additional filters

在这5个项目中，4个是单数并且工作正常，但是，additional filters是多个保存为奇怪的转义字符串。如果我发送只是保存过滤器，它看起来像这样：

"---\n- !ruby/hash:ActiveSupport::HashWithIndifferentAccess\n  type: city\n  value: San Francisco\n- !ruby/hash:ActiveSupport::HashWithIndifferentAccess\n  type: sport\n  value: Basketball\n- !ruby/hash:ActiveSupport::HashWithIndifferentAccess\n  type: sport\n  value: Football\n"

这是这些过滤器的输出： [{"type"=>"city", "value"=>"San Francisco"}, {"type"=>"sport", "value"=>"Basketball"}, {"type"=>"sport", "value"=>"Football"}]

我尝试了很多方法，但我不能按照我想要的方式清理它。如何避免HashWithIndifferentAccess或调整结果。

SCHEMA：

create_table "search_counts", :force => true do |t|
    t.integer  "search_countable_id"
    t.string   "search_countable_type"
    t.integer  "search_returns"
    t.datetime "created_at",            :null => false
    t.datetime "updated_at",            :null => false
  end

 create_table "search_count_details", :force => true do |t|
    t.integer  "search_count_id"
    t.string   "ip_address",      :limit => 15
    t.datetime "created_at",                    :null => false
    t.datetime "updated_at",                    :null => false
    t.string   "action"
    t.string   "query"
    t.text     "filters"
 end
