Rails - May 2008 - Nested URL Routing

Hi everyone,

I''ve been reading a lot of posts related to routing and URLS in Rails
lately but I still can''t figure out how to do this:

I have a controller (categories) where I''m using the BetterNestedSet
plugin in order to have a tree structure for categories for my web
project.  A "category" is basically like a folder.

I also have another controller (pages) where each "page" is
essentially an HTML-like page.  Each "page" is filed underneath a
certain "category".  All of this seems to work at the moment.  But I
can''t seem to find any information on how to display a "page"
as if it
were filed (like an HTML file in a web directory.)  So that it would
look something like this:

http://www.site.com/pages/category_a/category_b/category_c/page


Maybe this is the point where you (the reader,) are wondering, "why is
he doing it THIS way...?"  And if so, is there a better way to do
this?  I realize that if I eventually need to move a page to another
"category" the URL where it was at previously will now be broken.  But
for a simple website application it works for me.

Is there a way to have a route that allows for potentially unlimited
directories in the URL?

thanks,

andy

Yep, you can use route globbing:

map.file ''*directory/:file'', :requirements => {:file =>
/\w+\.\w+/}
map.directory ''*directory''

Then to generate lins to these URLs:

directory_path([''path'', ''to'',
''dir''])
file_path([''path'', ''to'',
''dir''], ''file.txt'')

The trick with globbing is that you need to have parts in your URL that
either conform to some requirements, or have a unique piece in them.
Otherwise, any route will match that route.

Hope that helps.

Brandon
