[Twisted-Python] authentification from a database
by vicky lupien Oct. 27, 2003

Oct. 27, 2003

I have a program that needs authentification from a database. For now, it's working fine but I'm using checkers.InMemoryUsernamePasswordDatabaseDontUse(test="test") (I want many users not only "test"). Here's my code: class RootPage(pages.BasePage): templateFile = "main.html" def initialize(self, dbpool=None): self.dbpool = dbpool def wchild_login(self, request): a=request.getComponent(simpleguard.Authenticated) if not request.getComponent(… [View More]simpleguard.Authenticated): return InfiniChild(login.LoginPage()) return Authenticated() class Authenticated(page.Page): isLeaf = 1 template='''<html><h1>Hello <span model="name"/>!</h1></html>''' def wmfactory_name(self, request): return request.getComponent(simpleguard.Authenticated).name class IRedirectAfterLogin(components.Interface): """The URLPath to which we will redirect after successful login. """ class Here(resource.Resource): def render(self, request): existing = request.getSession().getComponent(IRedirectAfterLogin, None) if existing is not None: request.redirect(str(existing)) request.getSession().setComponent(IRedirectAfterLogin, None) return "<html></html>" else: return util.redirectTo('.', request) def callback(model): return Here() class FullURLRequest: def __init__(self, request): self.request = request def prePathURL(self): r = self.request prepath = r.prepath r.prepath = r.prepath + r.postpath rv = r.prePathURL() r.prepath = prepath return rv class InfiniChild(resource.Resource): def __init__(self, r): resource.Resource.__init__(self) self.r = r def getChild(self, name, request): return self def render(self, request): request.getSession().setComponent( IRedirectAfterLogin, urlpath.URLPath.fromRequest(FullURLRequest(request)) ) return self.r.render(request) def createResource(): dbpool = database.DataBase().getConnection() return simpleguard.guardResource( RootPage(dbpool=dbpool), [checkers.InMemoryUsernamePasswordDatabaseDontUse(vicky="lupien")], callback=callback) #In an other module: class LoginPage(pages.BasePage): templateFile = "login.html" def initialize(self): self.title = "Login" def wmfactory_title(self, request): return self.title def wchild_index(self, request): return self def wvupdate_loginform(self, request, widget, model): root = request.getRootURL() if root is None: root=request.prePathURL() url = urlpath.URLPath.fromString(root) lmx(widget.node).form( action=str(url.sibling(guard.INIT_PERSPECTIVE)), model="form") def wmfactory_form(self, request): return guard.newLoginSignature.method(None) [View Less]

[Twisted-Python] Odd behavior in IRC logbot
by Phillip J. Eby Oct. 27, 2003

Oct. 27, 2003

I've been using a slightly modified version of the IRC logging bot example to log traffic on #peak. I've noticed, however, that it occasionally seems to hang, and has to be manually restarted. As a workaround, I've set up a cronjob to kill and restart it daily, but that seems like a kludge. Does anybody know why this happens? Is there some kind of reconnect timeout such that it'll give up on reconnecting if the server it's trying to connect to is down? I've noticed that the hang … [View More]

[Twisted-Python] Directory Listing fonts
by Philippe Lafoucrière Oct. 27, 2003

Oct. 27, 2003

Hi, I just discovered the new Twisted Web Directory listing look. It looks better, but why the fonts are so huge ? I mean, the <h1>Directory listing for ...</h1> could have been a <h2>...</h2> ? thx :)

[Twisted-Python] Picture_Pile broken?
by Kevin Unger Oct. 27, 2003

Oct. 27, 2003

Hello Twisted Folk, I just downloaded 1.1.0rc2 for Windows. The link from the woven howto to the source listings for the 'Picture_Pile' tutorial is broken. The link (at the bottom of the page) needs to have '.html' apended to the href. I found the listings (only a single and broken link to the file directory-listing4.html exists), and downloaded the files necessary to run the first part of the tutorial: directory-listing.html image-display.html picturepile.py … [View More]

[Twisted-Python] questions on twisted web server
by Alex Li Oct. 26, 2003

Oct. 26, 2003

Hi all, 1) I would like to rotate the logs for the web server. How should I do that? I have read the rotatinglog.py example, but I don't know how to intergrate that into the web server script below... 2) How to turn off directory listing? Am I doing the right way below? 3) I would like to use https for certain directories, but not the whole site. How do I do that (probably with 2 server.Site instances... I need more clues)? For example, if a user access the site through http://localhost/… [View More]

[Twisted-Python] Newbee needs help.
by John D. Oct. 26, 2003

Oct. 26, 2003

I've downloaded Twisted Python, and have spent considerable time trying to figure it out. Has anyone, or is anyone planning to write up a tutorial? In particular, I want to know how to process web forms page elements using the twisted web server code, or some examples on how to do it. I suspect there might be tools already present that can do this, and in normal Python, there is the "cgi" module, but not sure how I can use that module, or even if it's possible to process forms … [View More]

[Twisted-Python] importing twisted modules from my source tree
by Ricardo Niederberger Cabral Oct. 25, 2003

Oct. 25, 2003

(talking about Twisted 1.0.8alpha3) I'd like to ship my application source code with some twisted modules (mostly spread.pb and dependencies), but i'm facing some strange problems, which i guess are due to some magic done on files like twisted/internet/reactor.py: del sys.modules['twisted.internet.reactor'] Anyway, I placed the entire twisted dir inside my 'net' package, so other modules can import twisted from there. (later, i'd remove twisted modules i don't need). Since some twisted … [View More]

[Twisted-Python] application maker for twisted_1.1.0rc
by vicky lupien Oct. 24, 2003

Oct. 24, 2003

My OS is win2k. I installed twisted-1.1.0rc but I don't understand how application maker works. I want to start a web application on port 8585. Is there someone who can explain me how it works. The previous version was easy to use with the option "launch" but now it's "create". I'm really mix up. Vicky

[Twisted-Python] twistd and win32 service
by Justin Johnson Oct. 24, 2003

Oct. 24, 2003

Is it possible to have twistd run a .tap but do so within a windows service? The general consensus on the mailing list archives seems to be that I'd need to setup my code to not require twistd but just run standalone. However, since I'm running on windows I'd like to have twistd handle loading the win32eventreactor for me so I don't have to worry about import orders and all that. Thanks. -Justin
