無法使用回形針在軌道上保存圖像

我正在使用回形針上傳圖像。我的應用程序可以正確導入圖像，但無法保存。這裏是我的控制器：無法使用回形針在軌道上保存圖像

def create 
    @upload = Upload.new(params[:upload]) 
    logger.debug "image: #{@upload.image}" 
    logger.debug "image: #{@upload.image_content_type}" 
    logger.debug "image: #{@upload.image_file_name}" 
    if @upload 
     @upload.save 
     redirect_to uploads_new_path 
    else 
     render json: { error: @upload.errors.full_messages.join(',')}, :status => 400 
    end 
    end

HTML：

<div class="medium-10 medium-centered row"> 
    <div class="medium-10 medium-centered columns"> 
     <%= form_for(@upload,{:action=>"create", :controller=>"uploads", :method => "post"}) do |f| %> 
      <%= f.file_field :image %> 
      <br> 
      <%= f.submit "Upload" %> 
     <% end %> 
    </div> 
</div>

當我檢查日誌：

我的應用程序仍然正確導入圖像：

image: /system/uploads/images//original/Capture.JPG?1418984321 
image: image/jpeg 
image: Capture.JPG

但我無法保存到數據庫中。請幫我解決這個問題！

更新驗證：

validates_attachment :image, 
:content_type => { :content_type => ["image/jpeg", "image/gif", "image/png"] }, 
:size => { :less_than => 10.megabyte }

縱觀信息從回形針

[paperclip] Content Type Spoof: Filename Capture.JPG (["image/jpeg"]), content type discovered from file command: . See documentation to allow this combination.

你上傳的不是一個JPEG圖像獲取，但它包含不同的格式。嘗試上傳內容類型與文件擴展名匹配的圖像。

我想看看回形針文檔，看看如何處理這種情況

我試着導入窗口的示例圖片，但仍然是相同的錯誤。我添加了我的驗證，可能是問題 – 2014-12-19 10:48:33

的問題是在允許的參數，可以也應該是指教練，而不是司機按如下：

def permitted_params 
params.require(:instructor).permit(..., :avatar) 
end

對不起！我沒有使用帶有強參數的rails 4 – 2014-12-19 10:49:30
