Hello, To Kieran Holland: Wow! I haven't had a chance to study it all, but your stan tutorial is exactly the kind of clear, thorough documentation that will propell Twisted from outstanding to extraordinary. I hope I can do my part to suplement your work -- perhaps work with you on other parts of the problem. All the best, Lloyd

Hello, To Ed Suominen: Many thanks for your response. I'd very much appreciate your help. I am interested in Nevow, but like one of the other posters I'm confused about where Twisted leaves off and where Nevow begins. This is only one of many duh kind of questions I'd like to try to clear up. My personal goal in all this is to re-write a ColdFusion application in Python -- and improve it whereever possible. An example of the kind of sites I want the new Python site to support support can be found at http://www.luxexecutivesummit.com. I'm after: -- Scalability -- Modularity -- Rapid form-based site development -- Efficient form-based site maintenance -- Ability to plug in a rich variety of dynamic applications But I recognize that you have to walk before you run. So my first milestone will be to bring up the simplest web-server in the world. I know it's in the present documentation, but I haven't quite figured it out yet. I did get a couple of the Twisted examples working, however. My second goal is to make the site data-driven. My third goal is to tighten it up into an efficient, secure, flexible foundation that I and others can build on. My assumption is that if I, coming naively from a different technology, have questions, others will too. If I can stumble through to answers and help in whatever way to improve the documentation, then it'll be easier for others. More in following posts. Best wishes, Lloyd > > Today's Topics: > > 1.

Location of MSI for twisted 2.01 sumo
by Mike 06 Jul '05

06 Jul '05

Is there a MSI for twisted sumo? http://twistedmatrix.com/ suggests there is one in existence. I will continue to search, however if any one knows where I can obtain this, it would be appreciated. even some leads would be great so far have searched this mailing achive, twistedmatrix site, and many random dead ends as a result of inadequate search engine queries. Thanks

Is this expected behaviour? ---------------------- from nevow import loaders, rend, tags as T class TestPage(rend.Page): docFactory = loaders.stan( T.html(data=T.directive('showdata'), render=T.directive('showdata')) ) def data_showdata(self, context, data): print 'data_showdata:', data return data def render_showdata(self, context, data): print 'render_showdata: ', data page = TestPage([1,2,3]) page.renderSynchronously() --------------------- Output: data_showdata: <__main__.TestPage object at 0xb72bad4c> render_showdata: [1, 2, 3] I had expected that the data passed to the data_ method would be adapted via IGettable, for consistency between corresponding data_ and render_ methods. But perhaps there is a good reason for this behaviour which is not obvious to me? Kieran

I would like to setup a XML RPC server with authentication functionality based on username and password.Is there any simple example available for XML RPC server/client that uses username/password authentication? __________________________________ Discover Yahoo!

Thank you very much for your help Donovan. Now is working, but I can't see any error messages if I introduce a string and not a number. If I not worng, I should see that kind of message. Other question, if I want to sent the information from the form to another page, How can I do it?
