我必须模仿Google API响应并创建一个可由.
遍历的2级深度数据结构,如下所示:
=> user.names.first_name

有没有比这更聪明/更好的方法:
user = OpenStruct.new(names: OpenStruct.new(first_name: 'Bob'))
答案 0 :(得分:2)
这种方法粗鲁但有效,
require 'ostruct'
require 'json'
# Data in hash
data = {"names" => {"first_name" => "Bob"}}
result = JSON.parse(data.to_json, object_class: OpenStruct)
另一种方法是向Hash类本身添加方法,
class Hash
def to_openstruct
JSON.parse to_json, object_class: OpenStruct
end
end
使用上述方法,您可以将哈希转换为openstruct
data = {"names" => {"first_name" => "Bob"}}
data.to_openstruct
