rails attachment_fu public_filename问题

Question

attachment_fu会生成错误的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",

=> "/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'时，它生成“.gif”而不是“.png”（gif是父类型）

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？

感谢。

Answer 1

我明白了。

我没有指定：attachment_fu中的处理器，它使用任何安装的处理器。 我的开发机器有ImageScience和RMagick，我的生产机器只有RMagick。 ImageScience将gif调整为png，因为它无法很好地处理gif。
