Rails Attachment_fu public_filename 问题
Attachment_fu 生成错误的 public_filename。
>> pic.thumbnails => ProductPicture id: 12331, product_id: nil, parent_id: 12330, content_type: "image/png", filename: "b_9788994035109_mid.png", thumbnail: "mid", size: 16562, width: 205, height: 205, created_at: "2009-10-05 02:43:50", updated_at: "2009-10-05 02:43:50", ProductPicture id: 12332, product_id: nil, parent_id: 12330, content_type: "image/png", filename: "b_9788994035109_thumb.png", thumbnail: "thumb", size: 2300, width: 52, height: 52, created_at: "2009-10-05 02:43:51", updated_at: "2009-10-05 02:43:51" >> pic ProductPicture id: 12330, product_id: 23236, parent_id: nil, content_type: "image/gif", filename: "b_9788994035109.gif", thumbnail: nil, size: 73990, width: 400, height: 400, created_at: "2009-10-05 02:43:50", updated_at: "2009-10-05 02:43:50" >> pic.thumbnails => ProductPicture id: 12331, product_id: nil, parent_id: 12330, content_type: "image/png", filename: "b_9788994035109_mid.png", thumbnail: "mid", size: 16562, width: 205, height: 205, created_at: "2009-10-05 02:43:50", updated_at: "2009-10-05 02:43:50", ProductPicture id: 12332, product_id: nil, parent_id: 12330, content_type: "image/png", filename: "b_9788994035109_thumb.png", thumbnail: "thumb", size: 2300, width: 52, height: 52, created_at: "2009-10-05 02:43:51", updated_at: "2009-10-05 02:43:51" >> pic.public_filename => "/product_pictures/0001/2330/b_9788994035109.gif" >> pic.public_filename(:mid) => "/product_pictures/0001/2330/b_9788994035109_mid.gif"
当实际类型为“.png”(gif 是父类型)时,它会生成“.gif”而不是“.png”。
这适用于我的开发机器,但不适用于我的生产机器。
有什么想法吗?
谢谢。

attachment_fu generates wrong public_filename.

It generates ".gif" instead of ".png" when the actual type is '.png' (gif is the parent's type)
This works ok with my dev machine but not with my production machine.
Any idea?
Thanks.
Sam

我想通了。
我没有在 Attachment_fu 中指定 :processor ,它使用安装的任何处理器。
我的开发机器有 ImageScience 和 RMagick,而我的生产机器只有 RMagick。
ImageScience 将 gif 大小调整为 png,因为它不能很好地处理 gif。
I figured it out.
I didn't specify :processor in attachment_fu and it uses any processor installed.
My dev machine has ImageScience and RMagick and my production machine had only RMagick.
ImageScience resizes gif to png as it can't handle gif very well.
