ruby on rails - When using paperclip on Rails3, the some characters( @ and ~) get erased or altered from the file name when uploading -

I'm not sure that this is a paperclop problem. I tried it on gitlab and the same thing happened.

I have not written in the rail, there is a back end for the iOS app, and when I upload an image file with the @ character in the file name, it is erased by uploading, if I have a File, then

  aaa@2x.jpg    it is saved  
  aaa2x besides this, ~ _.   This is a problem because iOS apps estimate that retina supported images are designated with a @ 2x prefix.  
 I can upload the name of the file and convert it to the database and rename the file, but it seems that there is a strange hack to do this, anyone know what Its going on? According to this file, how is the name of the file saved properly?   
 
  According to this article: You must be able to use any characters, including NULL in file names . But OS Epi can limit some characters for heritage reasons.  
 This may be a server or a client problem, try debugging your app and check the file name given in  request.request_parameters  valid file name.  
 If you are going to use the uploaded files in the URL then you should transliterate them before uploading, this will also solve your problem. ? You can use this extension to do this: | File  
  module TransliteratePaperclip def transliterate_file_name (paperclip_file) paperclip_file = [paperclip_file] until paperclip_file.is_a (Enumerable) paperclip_file.each | Filename = read_attribute ("# {file} _file_name") if filename.present? Extension = File.extname (file name) .gsub (/^\.+/, '') file name = filename.gsub (/\.# {extension} $ /, '') self.send (file). Example_write (include: TransliteratePaperclip) putty: file_name, ". # {Filename.parameterize} # {extension.parameterize}") end-end end # extension ActiveRecord :: Base .send (include  /config/initializers/paperclip_transliterate.rb  in this code and in your paper clip model this code: | c    before_post_process {| transliterate_file_name (: file)}    Where  :. file is defined by  attribute  has_attached_file

apache - How to do an URL rewrite that works with a
pre-existing .htaccess file? -



    I have a platform that is currently available through the URL:    Www.websitecom / index.php? App = forum    Instead, I want people to be able to go here:      & lt; Ifmodule mod_rewrite.c & gt; Option - Multi Views RewriteEngine RewriteBase / RewriteCond on% {REQUEST_FILENAME}! -f Rewrite Convert% {REQUEST_FILENAME}! -d rewriteable /index.php [L] & lt; / IfModule & gt;    It seems that it should be possible, but I'm not sure how to do it.   Thank you!      This has not been tested, but something like that should be done. Add it before the first Rev.Directivity.    RewriteRule ^ forum $ /index.php?app=forums    Alternatively, you redirect from a 301 / forum to index.php URL .   By doing this:    301 / redirect the forum "http://www.website.com/index.php?app = forum    However, it seems that you want to make a proper rewrite, so the first option is better,
