I''m uploading files via file_column, any suggestions on how to detect the MIME type of a file? I''d rather not do it by a custom file extension parser. It looks like ruby has MIME/Type, but it doesn''t seem to read files. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

i think this should be what you want: # :blabla is assumed to be the name of the form file field. params[:blabla].content_type --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

if the file is being uploaded as part of a form, then you can use the
content_type method. If you''re reading the file from disk, you can
use the Mime::Types gem from http://mime-types.rubyforge.org/, in
which case you''d do something like:
content_type =
MIME::Types.type_for(''filename_with_extension'').first.content_type

What if you don''t have a filename with extension or the extension is unreliable? Is there any lib out there that can accurately detect type (mime type) by looking at the data itself?

Apparently, no lib can provide the auto detection type. If you''re using linux, use the command ''file'': `file -bi my_file`.strip On 11/14/06, Christopher J.
