Hi! How to use this? I can declare it only inside a controller, so i tried to do add this to application controller: def back redirect_to :back end so i could call in all my views link_to ''back'', :controller => ''application'', :action => ''back'' but it doesn''t work - there are no errors, but i''m still on the same page. -- Posted via http://www.ruby-forum.com/.
it has to be used in the controller... On Thursday, March 09, 2006, at 10:23 AM, szymek wrote:>Hi! > >How to use this?

It does work -- except that when you click on that link, you go from your current page to the ''back'' action, which will redirect you back to the current page. Why? Because your current page will effectively be the referrer URL! What you need is a helper called link_to_back or so, which will return the value of link_to request referrer. I actually have found it nice to have link_to_back to take in a :default option because you may not always have a referring page.

Thanks!!!
I supspected that this may be the case (because there were no errors),
but didn''t know how to do it in another way.
Now I''ve got something like this:
def link_to_back(text)
link_to text, request.env["HTTP_REFERER"]
end
How can i add this default parameter (as a hash) that you''ve mentioned?
And one more thing - is there an easy way to check if user has
javascript enabled? I could do:
link_to_function text, "history.go(-1)"
and if user doesn''t have javascript call
link_to text, request.env["HTTP_REFERER"]
