Carrierwave頭像上傳參數

我在爲我的用戶個人資料頁面實施具有carrierwave的頭像時遇到問題。我得到錯誤nil is not a valid asset source。我認爲這是因爲我不允許:avatar params。我不知道如何去允許在Page_controller.rb文件的我的個人資料頁面中使用頭像參數。配置文件頁面get 'user/:id' => 'pages#profile'的路由。該路由是通過用戶名查找用戶的獲取請求。Carrierwave頭像上傳參數

Pages_controller.rb

    def home 

    end 

    def profile 
     #find the user by username id 
     if(User.find_by_username(params[:id])) 
      #assign the username to the id params 
      @username = params[:id] 
     else 
      redirect_to root_path, :notice => "User Not Found" 
     end 
     #help me get the user post to only post on his page 
     @audios = Audio.all.where("user_id = ?", User.find_by_username(params[:id]).id) 

    end 

    #this is to upload the audio file 
    def upload 
     @newaudio = Audio.new 

    end 


end
