attachment_fu && image caching

rubyonrails-talk
1

I have a little problem:

I’m operating with attachment_fu object (:storage => :file_system), for instance @image. When I have to render it into the view, i’d like to use native helper <%= image_tag(@image.public_filename) %>, it generates the HTML code something like “. I suppose that digits after the ‘?’ is caching stuff. (?) How can I get clean filepath?. Just now i constrained to be using ‘The-Not-Rails-Way’: i’m ducking pure html tags <img src=”<%=@image.public_filename%>, thats a problem.

That is because my application logic needs to get in the next redirect action the renewed (post cropped) image, but not clean image path return me the previous image. Intresting that problem is actual just in IE and Opera. Safari and Firefox works just fine.

Thanks.

I have a little problem:

I'm operating with attachment_fu object (:storage => :file_system),
for instance @image. When I have to render it into the view, i'd like to use native helper < %= image_tag(@image.public_filename) %>, it generates the HTML code
something like "<img src="/images/image.jpg?2342323">. I suppose that
digits after the '?' is caching stuff. (?)

the digits are a timestamp for the file (so that if the file has changed the browser is forced to re-request it

How can I get clean filepath?. Just now i constrained to be using 'The- Not-Rails-Way': i'm ducking pure html tags <img src="<%...@image.public_filename %>, thats a problem.

Have you checked the output to see if that's generating the img tag you would expect?

Yes! the pure <img> generates exactly I need - filepath without timestamps and application works fine in all browsers.
