Hi all. I am wrting a small content management tool for my company and was trying to display some images from our file store shown below. <td> <img src="\\xx.xx.xxx.xx\xx\xx\xxx\abc.gif"/> The app was displaying the image when it is under the \public\images directory. Is there anything special we need to do to get a file from outside the root of the application? Any help appreciated. Thanks Silvy Mathews

Hi John, Thanks for the quick response. I wanted to show the image along with other data from the controller. How do I do that. Looks like I am not understanding it. <td><%= column1 from the model%> <td><%= column1 from the model%> <td><%= column1 from the model%> <td><%= send_file ''\\xx.xx.xxx.xx\xx\xx\xxx\abc.gif"'', :type => ''image/jpeg'', :disposition => ''inline''%> Would not work.

It is there that you would have the send_file command. Remember that in HTTP you are going to have seperate request for each item on the page, so map the new controller url using routes and use that url in your view, for example "/dynamicimages/abc.gif".

Hi Josh, Thanks for the clarification. Is there any online example somewhere that you are aware of so that I can see it in action?

Yea sorry my response was a little short - that function would go in the
controller, i.e.
class FileGrabberController < ApplicationController
def grab_file
send_file ''/path'', :type =>
''image/jpeg'', [etc]
end
end
then either call the controller directly using an image tag or use a helper..
let me know if that helps - I can post a working example when I get home
tonight [on the laptop at home]..

Hi,
Thanks a lot for the response. If you can post a working example, that
would be great.
Really appreciate it.
Thanks

Here''s a [very] rough, but working example for a PDF.. Controller: class FileGrabberController < ApplicationController @@path = ''your/path'' def get_file send_file @@path + ''a.pdf'', :type => ''application/pdf'' end end View: <a href="file_grabber/get_file">pdf</a> I know there''s an inline option as well, i.e. for a JPG :disposition => ''inline'' <img src="file_grabber/get_image"/> or something like that - hope that helps.. brez Silvy@funmail.com wrote:> Hi, > Thanks a lot for the response.

The browser then retrieves the img like a typical JPG. send_file returns a byte stream [i.e. no HTTP headers, etc] which is subsequently rendered.. It all pretty straightforward actually - it''s probably worth reading abt the HTTP 1.1 protocol if you found the previous few lines compelling.. -- Posted via http://www.ruby-forum.com/.
