Hi, which is the best way to upload an image, keep that and also make a thumbnail? The images should not be stored in the database, but as normal image files in a specific directory. I think that for the thumbnail i should use rmagick, but for the upload ? (something which work with and without javascript, in every browser) Thanks :) -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Just curious, is there any special reason as to why you would not want them stored in the database? How will you be referencing back to the images later? I know this not helping you original question, but I was just curious to know why you would not want them stored. --Cory On Jul 11, 3:11 pm, Mix Mix <rails-mailing-l...-ARtvInVfO7ksV2N9l4h3zg@public.gmane.org> wrote:> Hi, which is the best way to upload an image, keep that and also make a > thumbnail? > The images should not be stored in the database, but as normal image > files in a specific directory. > I think that for the thumbnail i should use rmagick, but for the upload > ?

I use attachment_fu with RMagick for this. It also supports lightweight image processors such as ImageScience. You can find a howto here: http://clarkware.com/cgi/blosxom/2007/02/24 Mike On 7/11/07, Mix Mix <rails-mailing-list-ARtvInVfO7ksV2N9l4h3zg@public.gmane.org> wrote:> > CPerry wrote: > > Just curious, is there any special reason as to why you would not want > > them stored in the database?

I''d do a system call to image magic''s convert program to make
the
thumbnail... about the best performance your going to get
def thumbnail(temp, target)
system(
"/usr/local/bin/convert #{escape(temp)} -resize 48x48!
#{escape(target)}"
)
end
DHH touches on this in "Outsourcing the performance-intensive
functions" on this blog page:
http://www.loudthinking.com/arc/2006_09.html
Not really following you on what your asking about with the how to
upload part of the question? and not sure what javascript has to do
with it? It should just be a file-upload field as far as the browser
goes. For saving on the server I do something like this in one of my
models:
def save_file(file_name, file)
fh = File.open(file_name, ''w'')
fh.write(file.read)
fh.close
end
def image=(img)
return if img.blank?
save_file("/whatever/name/for_my_file.jpg", img)
end
good luck!
