nevow development refresh
by Jeffrey Kunce 03 Apr '05

03 Apr '05

Hi- This is most probably FAQ, but I swear I couldn't find it - please have mercy on a nevow/twisted newbie :) If I make some changes in the python code for a nevow application, is there a way to refresh and test those changes without killing/restarting my twisted server? Thanks. --Jeff

Static.File and browser caching
by Matt Feifarek 31 Mar '05

31 Mar '05

Hello. Static.File doesn't seem to support any of the cache features that modern browsers use. There are various HTTP headers that govern this, including Etag, Cache-Control, Expires, etc. The Twisted server returns a comparatively minimal set of headers (hit twistedmatrix.com and look at the headers). Also, as far as I can tell, a "good citizen" HTTPD changes the response from a "200" to another response code that indicates "nothing new here", under certain circumstances. OR, it lets the browser figure that out... but it has to give the browser enough headers for it to do so. Is there a subclass of Static.File somewhere in Twisted that supports these features, or am I perhaps looking in the wrong place for this functionality? Thanks.

overdesign is me

Has anyone done anything like Archetypes from the zope world with Nevow? I.e take some schema description for a type and automatically from that make bare-bones views and editors for the object?

Weird issue with formless and Firefox/Mozilla
by Dave Cook 28 Mar '05

28 Mar '05

Short story: bizarre problem with a corrupted popdown list in Firefox and Mozilla on unix systems. I'm trying to render some unicode strings in a popdown, basing my code on the formpost2.py example in nevow 0.4.1: class IMyForm(annotate.TypedInterface): def composer(self, composers=annotate.Choice(choices=choices, label="Choose a composer", valueToKey=unicode, stringify=unicode, keyToValue=unicode, unicode=True), ): pass composer = annotate.autocallable(composer) The full code is here: http://members.cox.net/davecook/pythonstuff/test.py This seems to work great. Well, at least the unicode strings seem to roundtrip from the server to the browser, and there aren't any encoding tracebacks. That is, it works great in Safari, Konqueror, IE6, and win32 Firefox, but with Firefox (1.0.2) on OS X and Linux and Mozilla (1.7.6) on Linux the popdown gets corrupted and clicking on the popdown button is not effective, you have to click to the left of the button to popdown the menu, and the menu is misaligned. The scrollbar in the dropdown list even disappears on Linux. Unless my code is doing something nasty, I'm guessing this is a Firefox bug. So the next question is, how do I report a bug like this? Will they take a nevow script as a test case? Thanks, Dave Cook

Authenticating users and refering them to personal URLs based on the authentication result.
by Xif 24 Mar '05

24 Mar '05

Hi I'm just starting with Nevow, and wanted to know if this is possible, and if so get a few leads. I want: 1) to authenticate users (from a form with a "username" and a "password" field) based on data stored in a database. 2) after authentication is performed, the user is sent to a URL based on some of the data from the database. For example, if the database query revealed him to be named "John Smith", he shall be refered to http://appserver.com/JohnDoe. Subsequently, he should remain at this URL, and all links should refer to addresses "below" his personal address. For example, http://appserver.com/JohnDoe/configuration, http://appserver.com/JohnDoe/mail, etc. Thanks in advance, Xif

Nevow liveglue and proxy
by Thomas HERVE 24 Mar '05

24 Mar '05

I've just updated to nevow 0.4.1 and I enjoy the improvements, especially on the LivePage API. But i've found something that doesn't work for me in the new way to render livepage "glue" : the render_liveglue method uses the url.here() function, and as I'm using an Apache proxy to access the site it gives me "http://localhost:8080[...]" instead of the URL I'm accessing. For now I've set manually the liveglue.js in my header, and I think it's a clean way to do it, but I was wondering if there was a another way to get "good" URL (which means the one the browser see). Anyway thanks for that great work ! -- Thomas HERVE ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

Nevow + adbapi
by Luis N 23 Mar '05

I must be a total moron: I have this: def query(): return dbpool.runQuery("SELECT english FROM lang WHERE spanish LIKE 'hola'") def result(res): if res: print res[0][0] else: print "Failed." def words(ctx, data): query().addCallback(result) class PData(rend.Page): addSlash=True docFactory = loaders.stan(tags.html[ tags.div(data="words")[ words ]]) And I get this at the terminal, which is correct: 2005/03/10 23:30 GMT [HTTPChannel,0,148.241.73.37] 148.241.73.37 - - [10/Mar/2005:23:30:09 +0000] "GET / HTTP/1.1" 200 126 "-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)" 2005/03/10 23:30 GMT [-] hello But I get a big red None on the web.
