我試圖用它連接到其他模型中的註釋風格模型，但我不斷收到錯誤：accepts_nested_attributes
Review(#2171315060) expected, got Array(#2148226700)
使用參數：
Processing PlacesController#create (for 127.0.0.1 at 2010-04-15 18:57:02) [POST]
Parameters: {"commit"=>"Submit", "action"=>"create", "destination_id"=>"3243", "controller"=>"places", "place"=>{"address"=>"sdfsdf", "name"=>"dssfs", "lng"=>"", "reviews"=>{"content"=>"sdfsdfsdfsd"}, "website"=>"sdfsdf", "city_id"=>"3243", "lat"=>"", "place_type"=>"1"}}
我有這樣的父模型
has_many :reviews, :as => :reviewable, :dependent => :destroy
accepts_nested_attributes_for :reviews
這在審查模式
belongs_to :reviewable, :polymorphic => true
任何想法？
我有一些完全像這樣的工作與照片...也多態，它工作正常。我能看到的唯一區別是，我已經嵌套在這個模型中，所以形式如下：
<% form_for :place, :url => destination_places_path(@city), :html => { :multipart => true } do |f| %>
我也注意到，在這工作我有例如，輸出看起來是這樣的：
{"article"=>{"photos_attributes"=>{"1271403114089"=>{"data"=>#<File:/var/folders/9b/9b3G5CRzGk0okD2UGi-hvE+++TI/-Tmp-/RackMultipart20100416-26553-177jk7b-0>}}, "title"=>"dsfdfs", "excerpt"=>"", "content"=>"<p>\r\n\tsdfsdf</p>\r\n", "tag_list"=>"lala,lah"}, "commit"=>"Save", "action"=>"create", "controller"=>"articles"}
相比於一個不：
{"commit"=>"Submit",
"destination_id"=>"1461",
"place"=>{"name"=>"sdfasdf",
"address"=>"asdfasdf",
"photos"=>{"data"=>#<File:/var/folders/9b/9b3G5CRzGk0okD2UGi-hvE+++TI/-Tmp-/RackMultipart20100416-26553-8edo05-0>},
"lng"=>"",
"website"=>"asdfasdfs",
"reviews"=>{"content"=>"asdfasdf"},
"city_id"=>"1461",
"place_type"=>"1",
"lat"=>""}}
即一個MODELNAME_attributes vs MODELNAME ...我不知道爲什麼？這種形式似乎與嵌套的一個例外是一樣的？
