I would like to lauch a server from outside the side package directory how do i specify a path with import #/home/gert/Desktop/www/db/py/start-server.py import cherrypy class HelloWorld: def index(self): return #external htm file Hello world! index.exposed = True if __name__ == '__main__': # ??? dont know what is this for import os.path conf = os.path.join(os.path.dirname(__file__), 'conf-server.py') cherrypy.config.update(conf) cherrypy.quickstart(HelloWorld()) else: cherrypy.tree.mount(HelloWorld()) # ??? dont know what is this for #/home/gert/Desktop/www/db/py/conf-server.py [global] server.socket_port = 8080 server.thread_pool = 10 -- http://mail.python.org/mailman/listinfo/python-list

Http server
so far this works import cherrypy import os.path class Http: def index(self): f = open(os.path.join(os.path.dirname(__file__), '../htm/index.htm')) xml = f.read() f.close() return xml index.exposed = True cherrypy.tree.mount(Http()) if __name__ == '__main__': cherrypy.config.update(os.path.join(os.path.dirname(__file__), 'server.conf')) cherrypy.server.quickstart() cherrypy.engine.start() I would like a cute secretary for Christmas but i dont think i will get one. So i need to find a way to scan a directory. And map all files inside the directory and generate a class member like def filename(self): f = open(os.path.join(os.path.dirname(__file__), '../htm/filename')) xml = f.read() f.close() return xml filename.exposed = True Any idea or cute secretary maybe ? -- http://mail.python.org/mailman/listinfo/python-list

Re: Http server
Does anybody know how to redirect a post request ? i have a js file that does a post request to a /php/action.php file and i would like for the secretary to just do the action method instead that is defined in her python Http class book, so i can run both php and python without changing the static source code at 2 different ports head to head to see witch one can handle the most requests ? -- http://mail.python.org/mailman/listinfo/python-list
Re: def index(self):
> > class HelloWorld(object): > > @cherrypy.exposed > > def index(self): > >return "Hello World" do i have to write @cherrypy.exposed before every def or just once for all the def's ? and why not write something like @index.exposed ? in other words i have no idea what @ actually does i only know i have too write it to make it work :) Am guessing @ is something like prototyping in javascript but then def index is not a object but a method ? So that would not make sense ? oh and self stands more or less for private method right ? -- http://mail.python.org/mailman/listinfo/python-list

I was thinking if it would be possible to create a object that uses
it's own instance name as a atribute.
For example instead of
gert = Db('localhost','root','*','gert')
you would do this
gert = Db('localhost','root','*')
and the name of the object itself 'gert' get's assigned to database somehow ?
