BASE64照片和回形针-Rails [英] base64 photo and paperclip -Rails

问题描述

我想处理一个base64照片与回形针。
当我尝试：

I want to handle a base64 photo with paperclip.
When I try:

photo = Photo.new 
string = base64string

photo.photo = StringIO.new(Base64.decode64(string))
photo.save

这是行不通的。
为什么呢？

It does not work. Why?

先谢谢了。

推荐答案

请确保您使用StringIO是回形针打开之一。 <一href=\"https://github.com/thoughtbot/paperclip/blob/master/lib/paperclip/upfile.rb\">https://github.com/thoughtbot/paperclip/blob/master/lib/paperclip/upfile.rb

Make sure that the StringIO you are using is the paperclip opened one. https://github.com/thoughtbot/paperclip/blob/master/lib/paperclip/upfile.rb

 sio = StringIO.new(Base64.decode64(string))
 puts sio.respond_to?(:original_filename)
 puts sio.respond_to?(:content_type)

它需要有以便具有用StringIO回形针工作的那些方法。请确保它是设置他们。

It needs to have those methods in order to have paperclip work with StringIO. Make sure it is setting them.
