Rails - May 2006 - session[:return_to] for going back.

Hi,

Is session[:return_to] something Rails maintains to quickly go back to the
previous uri without having to keep track of the action name?  Or, do we
have to actually set it in our actions?

Thanks.

I am not sure if this is applicable for you but I use the following exta 
''link'' functions:

  #links back to page where it came with back_name
  def link_back(back_name, html_options = nil, 
*parameters_for_method_reference)
    request.referer or return ''''
    if html_options
      html_options = html_options.stringify_keys
      convert_options_to_javascript!(html_options)
      tag_options = tag_options(html_options)
    else
      tag_options = nil
    end
    "<a
href=\"#{request.referer}\"#{tag_options}>#{back_name ||
request.referer}</a>"
  end

  #links back to page where it came with back_name; otherwise falls back 
to link_to
  def link_back_or_to(back_name, name, options = {}, html_options = nil, 
*parameters_for_method_reference)
    ret = link_back(back_name, html_options, 
parameters_for_method_reference)
    return ret if !ret.empty?
    link_to(name, options, html_options, 
parameters_for_method_reference)
  end

for redirection you can use redirect_to :back

Not sure if this is what you are after.

Cheers,
Anton

(Assuming you''re referring to the earlier url_back code sample.)

You must set it yourself. Rails can''t tell which page you wish to  
return to or when such a setting is appropriate.

I like embedding return_to in form parameters because the user can  
work with multiple tabs/windows without having one tab return to the  
other''s :return_to.
