You can keep the url map in one single file but still define the classes
in separate files. You could probably even push the mapping for those urls
into the 'subapp' and append it's urls to the main url. You would still
need the full url, unlike a true subapp, and you would need to be careful
with the append because order matters.
I agree it would be nice to be able to use a regex to match on a url and
pass it to a subapp.
code.py
----------------------------------------
import web
import container
urls = (
"/containers/(\w+)/", container.FullList,
"/containers/(\w+)/attribute/" , container.Attributes,
"/containers/(\w+)/attribute/value/", container.AttributeValue,
"/containers/(\w+)/items/(\w+)/", container.Item,
"/main", "Main",
)
app = web.application(urls, globals())
class Main:
def GET(self):
return 'Main App page'
if __name__ == "__main__":
app.run()
container.py
------------------
class FullList:
def GET(self, container_id):
return "Full list. container:%s"%(container_id)
class Attributes:
def GET(self, container_id):
return "Attributes. container:%s"%(container_id)
class AttributeValue:
def GET(self, container_id):
return "AttributeValue. container:%s"%(container_id)
class Item:
def GET(self, container_id, item_id):
return "Item. container:%s item:%s"%(container_id, item_id)
