我正在尝试使用附加到另一个模型的评论样式模型,但我一直收到错误:
Review(#2171315060) expected, got Array(#2148226700)
使用params:
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"}}
我在父模型中有这个
has_many :reviews, :as => :reviewable, :dependent => :destroy
accepts_nested_attributes_for :reviews
这在评论模型中
belongs_to :reviewable, :polymorphic => true
有什么想法吗?
我有一些与照片一样的工作...也是多态的,工作正常。我能看到的唯一区别是我已经嵌套了这个模型,因此表单看起来像这样:
<% form_for :place, :url => destination_places_path(@city), :html => { :multipart => true } do |f| %>
我也注意到,在我的示例中,输出看起来像这样:
{"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"}
与没有的相比:
{"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。一个人有MODELNAME_attributes vs MODELNAME ...我不知道为什么?表格似乎与嵌套的一个例外相同吗?
答案 0 :(得分:0)
确保使用fields_for
获取嵌套对象的表单构建器。
