我有一個簡單的類,當用戶請求服務器時,我想以JSON形式輸出。[棄權] MultiJson.decode已棄用
class GeoName
include ActiveModel::Validations
include ActiveModel::Serialization
validates :country_name, :presence => true, :length => {:minimum => 1}
validates :country_code, :presence => true, :length => {:minimum => 1}
validates :province, :presence => true, :length => {:minimum => 1}
validates :district, :presence => true, :length => {:minimum => 1}
validates :zip_code, :presence => true, :length => {:minimum => 1}
validates :city, :presence => true, :length => {:minimum => 1}
validates :street, :presence => true, :length => {:minimum => 1}
attr_accessor :country_name, :country_code, :province, :district, :zip_code, :city, :street
def attributes
@attributes ||= {'country_name' => country_name, 'country_code' => country_code, 'province' => province,'district' => district,'zip_code' => zip_code,'city' => city, 'street' => street}
end
end
在控制器我以下:
def index
geoname = GeoName.new
geoname.street = "blablabla"
geoname.city = "blablabla"
render :json => geoname.to_json
end
在routes.rb中
controller :testcontroller do
match 'testme', :to => :index
end
當我請求URL本地主機:3000/TESTME我接收到有效的JSON響應。然而,在控制檯上存在棄用現象
rvm/gems/[email protected]/gems/activesupport-3.1.0/lib/active_support/json/decoding.rb:12:in `decode': [DEPRECATION] MultiJson.decode is deprecated and will be removed in the next major version. Use MultiJson.load instead.
