Question

我有一个rails应用程序。我通过Ajax调用获得了JSON数据，现在我想将我的JSON数据导入应用程序数据库。我该如何存档？谁能帮我？提前谢谢。

--- ---更新
我的应用程序有一个Task模型和User模型。用户有很多任务，任务属于用户。用户登录后，我将进行Ajax调用（jQuery getJSON）从另一个服务提供者获取JSON数据。我想将JSON数据作为任务导入数据库。

如果您还没有JSON gem，可以通过命令行安装它：

gem install json

这将允许您将JSON解析为其等效的Ruby数据结构。

如果JSON已经与您的模型匹配，您只需要执行以下操作：

new_record = Model.new(JSON.parse(json_string_from_external_service)) 
new_record.save

如果它不匹配您的型号，您可以执行以下操作：

a_hash = JSON.parse(json_string_from_external_service)

然后你只需复制你的属性并保存：

new_record = Model.new
new_record.attribute_1 = a_hash['key_for_attribute_1']
... etc ...
new_record.save

我可以使用我的rails应用程序将JSON数据导入数据库吗？
