Hello everybody,
I have some troubles with uploading files in my Rails project.
I use Rails 3, Ruby 1.9.2, rack 1.2.1, and both webrick / passenger on
apache
I was investigating and have isolated the strange behaviour on a
simple empty project:
view:
<% form_tag({:action => ''upload''}, :multipart =>
true) do %>
<%=text_field_tag :desc %>
<%=file_field_tag :file %>
<%=submit_tag %>
<% end %>
controller:
class IndexController < ApplicationController
def index
end
def upload
render :text => params[:desc] + params[:file].original_filename
end
end
The problem occurs, when I use national-specific characters in both
"desc" field and the name of the file I''m uploading
Error:
incompatible character encodings: UTF-8 and ASCII-8BIT

This is obviously just a silly example. But my real application makes
use of the paperclip gem to attach gallery images to documents.
# encoding: utf-8
class GalleryImageController < ApplicationController
def create
@image = GalleryImage.create(params[:gallery_image])
redirect_to ''/'' + @image.document.url
end
end
# encoding: utf-8
class GalleryImage < ActiveRecord::Base
belongs_to :document
has_attached_file :image, :styles => {:thumbnail =>
"250x200#"}
end
When user tries to upload a file with name containing local characters
and at the same time enters a description containg these characters, I
get this error - only difference is, that it is burried somewhere deep

I''m able to make a workaround like this:
def create
# force encoding of the original filename to utf-8
params[:gallery_image]
[:image].original_filename.force_encoding(''utf-8'')
@image = GalleryImage.create(params[:gallery_image])
redirect_to ''/'' + @image.document.url.url
end
But I don''t think it''s supposed to be like this.
Shouldn''t rack take
care of this for me ?
Thanks for contributions,
Best regards
