Paperclip - How to control which characters are escaped/changed to an underscore in an uploaded filename?
paperclip, ruby-on-rails
Solution
After some digging I found this undocumented option for has_attached_file:
:restricted_characters
The default value of this option seems to be this:
:restricted_characters => /[&$+,\/:;=?@<>\[\]\{\}\|\\\^~%# ]/,
The last one is a space. Remove it and you're good.
Problem
In a recent paperclip gem upgrade I noticed that the uploaded filenames are being modified and some characters are being changed to an underscore. I don't not like the fact that it changes spaces to underscores. What's wrong with a space in a file name? The 90's are long over..
