Browser caching creating problems while updating an image on

Rails
1

Hi,

On one of the views I display an image “some_week.jpg”, which basically
displays a graph for data corresponding to a particular week, by default
current week.
Following is the code snippet in view which displays an image,

On this view, User has an option of selecting some other week and see
the
graph corresponding to it. I have implemented this using an AJAX call
where
the graph image is constucted using Gruff library on server side and
following response is sent back from RJS,
imageTag =""
page.replace_html ,“image_place_holder”, imageTag

where, session[:user_id] =1 and @picName = “some_week.jpg”

After the response the image in the browser is still the old image, I
verified on server, the new image is created in the mentioned directory
but
browser seem to cache the old image.

I am using Mozilla Firefox 1.5.0.7.

Help is appreciated.

Regards,

Jatinder

Timestamp the image.

image_tag should do this automatically (if you put your image in
public/images):

image_tag('some_week.jpg") or you can do

The first is more elegant in that it tracks date modified time of the
file
to generate the asset timestamp.
