Rails 中嵌套表单的未知属性
我无法让我的 InventoryItem 接受嵌套属性，这很奇怪。
在我的脚本/控制台中，我执行了以下操作：
>> InventoryItem.create!(:name => 'what', :image_attributes => [ {:image => File.open("/home/davidc/Desktop/letterbx.jpg", "r") }])
ActiveRecord::UnknownAttributeError: unknown attribute: image_attributes
我不确定为什么在我的模型中收到未知属性错误，我已经执行了accept_nested_attributes。
我正在使用 Rails v2.3.5。

class InventoryItem < ActiveRecord::Base
uuid_it
belongs_to :user
has_many :orders
has_many :images, :validate => true
accepts_nested_attributes_for :images
end

class Image < ActiveRecord::Base
belongs_to :inventory_item
has_attached_file :image, :style => { :medium => "300x300>", :thumb => "100x100>" }
end
I'm having trouble getting my InventoryItem to accept nested attributes which is strange.
In my script/console, I did the following:
>> InventoryItem.create!(:name => 'what', :image_attributes => [ {:image => File.open("/home/davidc/Desktop/letterbx.jpg", "r") }])
ActiveRecord::UnknownAttributeError: unknown attribute: image_attributes
I am not sure why I'm getting the unknown attribute error when in my model, I already did accept_nested_attributes.
I'm using Rails v2.3.5.
Inventory Item Model
class InventoryItem < ActiveRecord::Base
uuid_it
belongs_to :user
has_many :orders
has_many :images, :validate => true
accepts_nested_attributes_for :images
end
Image
class Image < ActiveRecord::Base
belongs_to :inventory_item
has_attached_file :image, :style => { :medium => "300x300>", :thumb => "100x100>" }
end

您有
has_many :images所以，它应该是
:images_attributes，而不是:image_attributes当你有
has_many关系时，使用哈希数组是正确的You have
has_many :imagesSo, it should be
:images_attributes, not:image_attributesAnd it is correct to use array of hashes when you have
has_manyrelationship:image_attributes应该是一个哈希值。:image_attributesis supposed to be a hash.
