Rails - May 2008 - Problem with redirect_to and URL structure since upgrade to rails 2.0

Hi,

I have written a littel rails application with rails 1.x , and used
something like

redirect_to   :controller => "aaa" ,  :action => "bbb"
, :id => 123

within a controller to jump into a different controller''s action. It
worked.


Since upgrade to Rails 2.0 it does not work anymore, but generates an
error message like

Couldn''t find  SomeModelClass with ID=bbb


As far as I can see the URL structure has changed from rails 1.3 to
2.0

it was             /controller/action/id
but now is      /controller/id/action

where e.g.    /controller   is mapped to ''index'' and  
/controller/
id   is mapped to ''show''



Does anybody know why this was changed and how to use redirect_to
right now?

regards

You could use restful routing.

Well, I had a view on that restful routing thing and found that I
can''t use it, it breaks some
of the functionality.


I had a special action in my rails application that gets the
caller''s  :controller, :action, and :id to enable
returning to the page where it came from. This was easy since
redirect_to  would take variables as
parameters.

I do not see how this would work with restful routing, since it
defines fixed macros for the pathes.


Who decided to use restful routing with rails?

To your first question, you should have a route in your routes.rb that 
looks like:

  map.connect '':controller/:action/:id''

That is how you want it to stay compatible with your old rails app. 
Restful routes look more like:

  '':resource_name/:id/:optional_action''

Where optional action is not a basic CRUD operation (new, edit, promote, 
rate, etc.)  So make sure your defined routes are the right format.


Now to keep track of where a user was, you dont need to 
controller/action/id.  You can capture the URI of the request.  In your 
controller, you can do

  def save_location
    session[:return_to] = request.request_uri
    #=> "/some/path_to/something/123"
  end

  def restore_location
    redirect_to session[:return_to]
  end

So rather than controllers and actions, you simply capture the string 
url path, and it works great with redirect_to.
