# Multiple web apps
The approach I am proposing here is slightly different from the one
proposed by Adam Atlas in https://bugs.launchpad.net/webpy/+bug/119365.
import web
app = web.app()
urls = ("/.*", "hello")
class hello:
def GET(self):
print "hello, world!"
if __name__ == "__main__":
app.run(urls, globals())
Each app maintains its own state including loadhooks, unloadhooks etc.
It is possible to implement this without breaking the backward
compatibility.
This approach can be extended to support multiple subdirs and
multiple subdomains by adding app.setup method.
# blog.py
import web
app = web.app()
urls = ("/.*", "blog")
app.setup(urls, globals())
class blog:
"blah blah blah"
pass
# wiki.py
import web
app = web.app()
urls = ("/.*", "wiki")
app.setup(urls, globals())
class wiki:
"blah blah blah"
pass
# subdir.py
import web
import wiki
import blog
app = web.subdir_app("/wiki", wiki.app, "/blog", blog.app)
if __name__ == "__main__":
app.run()
# subdomain.py
import web
import wiki
import blog
import web20
app = web.subdomain_app(
"wiki\.example\.com", wiki.app,
"blog\.example\.com", blog.app,
".*\.example\.com", web20.app)
if __name__ == "__main__":
app.run()
Using these multiple applications can be combined into one single web
application very easily.
# Multiple databases
import web
app = web.app()
db = web.database(app, dbn='mysql', db='wiki', user='root',
pw='', pooled=True)
class wiki:
def GET(self, path):
d = db.query('SELECT * FROM wiki WHERE path=$path",
vars=locals())
....
Since all the state is stored in the db object, it is possible to
create multiple DB connections. app is passed to the database because
it needs to register a look hook with the app.
Again here also it is possible to maintain backward compatibility.
