Rails - 创建模型及其嵌套资源

Question

我试图通过将以下内容传递给create来创建Gallery模型及其has_many关联。

[ 
    { 
    "title":"Some Titler", 
    "description":"", 
    "date":"18-3-2012", 
    "photographs":[ 
     { 
     "title": "Some Title", 
     "camera": "Canon 600D" 
     }, 
     { 
     "title": "Some Other Title", 
     "camera": "Canon 600D" 
     } 
    ] 
    } 
] 

没有嵌套photographs阵列，它工作正常，但有了它，我得到一个错误：

Photograph(#70242279271180) expected, got Hash(#70242248401160) 

什么是错的语法？

class Gallery < ActiveRecord::Base 
    attr_accessible :date, :description, :published, :title 


    has_many :photographs 
    accepts_nested_attributes_for :photographs 

end 

Answer 1

变化

"photographs":[] 

到

"photographs_attributes":[]
