「関連タイプの不一致」？クリップ

Question

で、私はよく、ユーザavatar.Evreryもの作品をアップロードするにはペーパークリップを使用していますが、私は、保存ボタンを押したとき、私はエラーを得た：ここ

ActiveRecord::AssociationTypeMismatch in UsersController#update 

    Usernote(#79841148) expected, got Array(#25890648) 

    Request

は私のモデルである：

class User < ActiveRecord::Base 
    has_attached_file :avatar, 
        :styles => { 
         :thumb => "75x75#", 
         :small => "100x100#", 
         :medium => "150x150>" 
        }, 
        :default => :thumb, 
        :url => "https://stackoverflow.com/users/user_avatar/:attachment/:id/:style/:basename.:extension", 
        :path => ":profitnext/public/images/users/user_avatar/:attachment/:id/:style/:basename.:extension" 

# avatar validations 
    validates_attachment_size :avatar, :less_than => 5.megabytes 
    validates_attachment_content_type :avatar, :content_type => ['image/jpeg', 'image/png'] 
end 

と私表示：

<%= image_tag @user.avatar.url %> 
       <%= image_tag @user.avatar.url(:thumb) %> 

私はエラーがbutton.I保存打った後、事前にこのlot.Thanksに苦しんだということです。

これはペーパークリップとは関係ありませんが、thisの行に沿っています。 Userモデルにhas_many :usernotes、Usernoteモデルにbelongs_to :userがありますか？
