我需要渲染Json一个复杂的结构.我有下一个结构工作：
render :json => @booking,:include => [:paypal,:boat_people,:boat => {:only => :boat_model,:include => {:boat_model => {:only => :name,:include => { :boat_type => {:only => :name}}}}}]
但是我无法将一些其他嵌套属性的port属性添加到：boat,例如：boat_model(在同一级别).
更新：
虽然它不起作用,但我包含了我的port属性.
render :json => @booking,:boat => {:only => [:boat_model => {:include => {:boat_model => {:only => :name,:include => { :boat_type => {:only => :name}}}}},:port => {:include => :city => {:only => name}}]}]
我的意思是,boat_model和port都是船的属性.
这是模型对象：
class Boat < ActiveRecord::Base
attr_accessor :price
@price
attr_accessor :extrasPrice
@extrasPrice
def as_json(options = { })
h = super(options)
h[:price] = @price
h[:extrasPrice] = @extrasPrice
h
end
belongs_to :boat_model
belongs_to :port
belongs_to :state
has_many :photos
end
解决方法
我知道了.
render :json => @booking,:boat => {:only => :name,:include => {:port => {:only => :name,:include => {:city => {:only => :name,:include => {:country => {:only => :name}}}}},:boat_model => {:only => :name,:include => {:boat_type => {:only => :name}}}}}]
