My app has user-specific images that should be accessable like this:
http://mydomain.com/user/image/12
(returns a png image)
or like this:
http://mydomain.com/user/image/12.png
(the ".png" gets stripped from the id, returns a png image)
I've tried this:
- class UserController < ApplicationController
-
- def image
- render_file "#{path_to_png_image_file}"
- end
-
- end
but when i run it all that gets rendered is the string "‰PNG"
Any ideas?
Lindsay

Try taking a look at the send_data method. http://api.rubyonrails.com/classes/ActionController/Streaming.html#M000044 It looks like it may be what you need.

Thanks Aaron, It does look like what i need - but i can't get it to work. Here's my code: - class UserController < ApplicationController - - def image - send_file "path_to_image.gif", :type => "image/gif", :disposition => "inline" - end - - end When i do this: - http://mydomain.com/user/image I get this: - The image "http://mydomain.com/user/image" cannot be displayed, because it contains errors. And if i change the dispositon to 'attachment' the file i download also has errors. I am sure the original is fine. Anyone know why?

Hi Lindsay I was having the same issue as yours; it''s working fine since I set the stream option to false. send_file a_file, :disposition => ''inline'', :stream => false, :type => ''image/gif'' In my case, the file is really small (43 bytes), so setting the stream option to false wont affect performance. This seems to be a known issue: http://dev.rubyonrails.com/ticket/1812 Cloves Carneiro Jr --- Lindsay Bernath <hellolindsay-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> Thanks Aaron, It does look like what i need - but i > can''t get it to work. > > Here''s my code: > > - class UserController < ApplicationController > - > - def image > - send_file "path_to_image.gif", :type > => "image/gif", > :disposition => "inline" > - end > - > - end > > When i do this: > - http://mydomain.com/user/image > > I get this: > - The image "http://mydomain.com/user/image" cannot > be displayed, > because it contains errors. > > And if i change the dispositon to ''attachment'' the > file i download > also has errors.
