回形针导轨从base64图像获取扩展

Question

I know that paperclip gem automatically detects base64 data and turn it to image, but the saved file name is ' data?12345 ' (without any extension), even though the base64 starts with

data:image/png;base64,iV...IlNJZUPAAAAAElFTkSuQmCC

in which I can see clearly that the extension should be .png

Is there any way to tell paperclip to add the extension from base64 data?

Answer 1

my workaround is to appoint an extension to the formats, so no need to worry about the original extension.

has_attached_file :avatar, :styles => { :original => ["400x400>",:jpg]}

it's not perfect but works for me.
