I'm writing a admin website which control several websites with same program and database schema but different content. The URL I designed like this:

http://example.com/site                 A list of all sites which under control
http://example.com/site/{id}            A brief overview of select site with ID id
http://example.com/site/{id}/user       User list of target site
http://example.com/site/{id}/item       A list of items sold on target site
http://example.com/site/{id}/item/{iid} Item detailed information
# ...... something similar

As you can see, nearly all URL are need the site_id. And in almost all views, I have to do some common jobs like query Site model against database with the site_id. Also, I have to pass site_id whenever I invoke request.route_path.

So... is there anyway for me to make my life easier?

Thanks in advance.
