redirect_to :back - Any way to go back two pages?

I’ve run in to a strange situation where it would be great if there were a way to use " redirect_to :back " to skip back over the previous page and go to the previous, previous page ( :back X 2.) Any one have any ideas how to do this? I think I might end up trying to use the session some how, but want to avoid implementing my own system if possible.

Thanks!

The best thing that you can do is store the link where you want the
application to redirect_to in a later stage
and use it with the redirect_to syntax

eg:
session[:return_to] = request.fullpath (use this inside the controller
action where you would like to redirect to)
and then use
redirect_to session[:return_to]

If you don't mind to use Javascript for it, you could use
window.history.go(-2) (More on that here:
https://developer.mozilla.org/en/DOM/Manipulating_the_browser_history#Moving_to_a_specific_point_in_history)

How are you currently paginating? Some of the existing pagination
gems might (I haven't looked) have features to provide individual
links to the next and previous *few* pages, maybe even adjustable.
For instance, if you're on page 7 out of 24, it might provide not only
arrows to 6 and 8, but numeric links to 4, 5, 6, 8, 9, and 10 (and
possibly arrow and/or numeric links to 1 and 24).

I was trying to avoid this approach as I expected it would be a little complex, but your code shows that it is pretty straightforward. Thanks for taking the time to write it out.

Thanks for the idea. Unfortunately the :back :back process that I need to do is back to a previous model in a different view, so pagination won’t do it for me.

Cool! Had not thought of this approach at all. I have very weak JS skills, but I’ll look into this.

Hi Don.

FYI, Attached is a screen shot of how I see your 3 recent mails in Gmail. To me they

seem like 3 short messages without context. I think you could get more help/feedback

if you leave a little context quoted above, showing to what you are actually responding.

I double checked in the original message text (as presented to me by Gmail) and that

seems to confirm that there is not real quoted context.

No big problem, it’s just that you might get more/better feedback with proper quoting

a context.

Hope This Helps,

Peter

Just don't dare top-post, without nomex on. :wink:

Dave, thanks for the hint :slight_smile:

Don, sorry for being pedantic.

Thanks Peter. Appreciate the feedback.

If you can do it in JavaScript, you can always just do window.history.go(-2)
