Is it possible to pass a parameter automatically to every rails
generated link?
for example:
I have the parameter site_id which is passed via url
(www.example.com/:site_id/:controller/:action/:id)
is it possible to automatically pass the :site_id to all links/paths
like f.i. "articles_path", "article_path(@article)" or is the only way
to do this by passing the parameter in addition:
"articles_path(:site_id=>params[:site_id])" or
"article_path(@article, :site_id=>params[:site_id])".
I don't know the answer but if you are simply passing it backwards and
forwards in order to persist it then you might be better off using the
session. (session[:site_id] = ...)
thanks, but this is not really what i'm looking for.
I looking for a solution to (re-)pass a given parameter to all rails
generated links.
And why won't a session variable do the trick? It seems to me that
Colin is right.
You *could* override some of the UrlWriter functions, but you really,
really want a session variable, unless there's something I don't
understand here.
Ok, sessions seems to be right, but not what I'm looking for
This parameter is not static, it is dynamic. the whole thing is for a
CMS where the ":site-id" tells where the user stands in the navigation
and what's the site title,... So it would be much better to pass this
by url.

I would suggest that if you are using it for context information
(where the user is now) then the session is exactly the right place to
put it. Just update the session each time the value changes. A URL
is for indicating what to do next, not passing where you are at the
moment.
By the way it is generally preferred not to top post on this list, it
is easier to follow a thread if you insert your comments inline in the
previous message. Thanks.

Hi
I think you didn't understand what I mean...
Every Controller is something like a module in this cms. so you can
put such a module on different places on the website.
so you have a navigation, which points to a module (contoller) and a
certain place, where this module is placed within the navigation.
In this case the URL should also contain the site-id (navigation-id)
in order to find out which content of the module is part of this
navigation item. So you can't pass this via session.
For example:
we habe a news-module which is placed on the home page (site_id = 1)
and under "about > blog" (site_id = 99).
so the url would look like this:
www.example.com/1/news for the home page and www.example.com/99/news
for the "about > blog" page.
