将“复杂”JSON数据转换为哈希值

Question

我正在使用Ruby on Rails 3，我正在尝试转换以下JSON数据

"{\"errors\":{\"base\":\"Invalid field.\"}}"

以这种方式访问​​哈希：

@internal_test1[:errors][:base]
# => "Invalid field"

怎么做？

UPDATE

@internal_test1 = "{\"errors\":{\"base\":\"Invalid email/password combination.\"}}"
test = ActiveSupport::JSON.decode(@internal_test1)
@internal_test2 = test["errors"]

调试是

@internal_test1
--- "{\"errors\":{\"base\":\"Invalid email/password combination.\"}}"

@internal_test2
--- 
base: Invalid email/password combination.

 => {"errors"=>{"base"=>"Invalid field."}} 
> @internal_test1["errors"]
 => {"base"=>"Invalid field."}
