Rails - Jun 2006 - Importing images with file_column over http?

I haven''t cracked the source of file_column just yet - but has anyone
worked
out a way to snag images via URL instead of a file upload?

Optimally I''d like to have my clients be able to upload a file, or
enter in
a URL to store as file on the system.

Any/all help would be cool.

Try something like this:

  require ''open-uri''

def fetch_resource(options={})
    File.open(options[:to], "wb") { |f| f.write open(options 
[:from]).read }
end

fetch_resource :from => "http://example.com/foo.gif",
                             :to => "#{RAILS_ROOT}/public/assets/ 
foo.gif"


Cheers-

Thanks EZ, but that''s the easy part :)

The hard part is getting file_column to take it and do its magic. Guess I
need to look into the source. I saw a BaseUploadedFile::assign that might be
useful in combination with your code.

That got me on the right track...here''s my full controller method.
image_url
is pre-populated most of the time by my data import scripts.

Hopefully someone else finds this snippet useful.

  # Imports an image from the item''s url and feeds it into the image
upload
  # field.
  #
  # file_column automagically resizes it, and we set the item to use the
newly
  # uploaded image
  #
  def import_image
    require ''open-uri''

    @item = Item.find(params[:id])
    if !@item
      redirect_to :back and return
    end

    import_from = @item.image_url.clone
    chop_position = import_from.rindex("/")

    file_name = import_from[chop_position+1..import_from.size-1]

    save_to =
"#{RAILS_ROOT}/public/item/image_upload/test/#{file_name}"
    File.open(save_to, "wb") { |f| f.write open(import_from).read }

    @item.image_upload = File.open(save_to)
    @item.image_use_option = 2

    @item.save

    redirect_to :action => ''edit'', :id => @item
  end
