View html source of _manage_
by Andrew Diller 21 Feb '00

21 Feb '00

Hello: In my ZClass, I want to create a new View to change the attributes of an instance. Thanks to kdie on this list, I understand how to create the view in my ZClass and have it appear as a tab when I MANAGE the instance. I still need some pointers to where the source html is from the default manage 'tab' is. here is a url: http://xxx.upenn.edu:8080/projects/Rebuild_Bleep/propertysheets/InstanceCon… This manage screen is the deafult created for me when I built my PropertSheet (InstanceConstants). Whenever I look at the source for this, its always got all the particulars of the instance 'rendered' in. Where can I find the method (and view its source) that creates this page? I'm trying of course to customize the form which is displayed. It is to small for the attributes that I need. thanks for any pointers, andy - - - - - - - - - - - - - - - - - - - Andrew Diller dillera(a)isc.upenn.edu Information Systems and Computing Unix Systems Group University of Pennsylvania v: 3-7360 f: 8-9348

Hi, Did anyone already worked with tinyTables? If yes, do you know how can I add some information from a form to the tinytables? What I have is: In the TinyTables, the columns are: N.º , Name, Address, Home_phone, Cel_phone, Birthday_Date The code that I has implemented in the data textarea is: "<dtml-var fname> <dtml-var lname>" , "<dtml-var address> <dtml-var fzip>-<dtml-var restzip> <dtml-var localzip" , "<dtml-var home_phone>" , "<dtml-var cel_phone>" , "<dtml-var year_date> / <dtml-var mes_date> / <dtml-var dia_date>" As you know, the N.º column is assumed as index. The fname, lname, address, fzip, restzip, localzip, home_phone, cel_phone, year_date, mes_date and dia_date, are the names of the fields in a form. When I push the add button in the form, it will call the tinytables and will execute the code above. I'm calling this tinytable like this: <dtml-call "tab_registos">, that is the name of the tinytable. What is happen is that this isn't working. If you know hoe can I do this to make it work, please I would like that you could help me!!! Please, if you want to help me, send your answers to: psilva(a)ruido-visual.pt Thanks, Pedro - (Portugal)

DateTime bug (and ZSybase buglet)
by Brian Takashi Hooper 21 Feb '00

21 Feb '00

Hi there - (I've taken the liberty of also submitting these bugs to the Collector...) I think I found a bug with ZSybaseDA (the newest version) - here's the deal: I have a table in Sybase with a DateTime field. When I get a time back from it, the value of the field gets set in sy_occbf.c to something like: (2000, 2, 21, 22, 31, 59.63) The second value is being set to double (on purpose, looking at the sy_occbf.c code). The problem with this is that DateTime doesn't correctly validate floating point hour/min/seconds. The documentation string seems to say that DateTime can take (from the DateTime 1.43 doc string) "floating point, positive or negative offsets in units of hours, minutes, and days," for the fourth, fifth and sixth arguments - should this instead be "positive integer values for hours, minutes, and positive floating point values for seconds"? I think the latter might be simpler and easier to understand... Anyways, right now what DateTime is closer to this anyway - it validates times by calling self._validTime(h, m, s), which is defined: def _validTime(self,h,m,s): return h>=0 and h<=23 and m>=0 and m<=59 and s>=0 and s<=59 I was lucky enough to stumble on the case where 59 < s < 60; this could be taken care of by: def _validTime(self,h,m,s): return h>=0 and h<=23 and m>=0 and m<=59 and s>=0 and s<60.0 Of course, it's obvious that negative hour or minute offsets are also not going to work... The Sybase DA end of the thing - as I started out by saying, I noticed all this because the results that Sybase returned didn't convert correctly. Specifically, an exception was raised where SybaseDA was in the middle of handling a fetched result set: (in db.py, DA.query()...) if type(v) is TupleType: v=apply(converters[t], v) Because an exception is raised in the middle of fetching a result set, the command structure still has results left to fetch - this makes the next call to cm.ct_command() fail - Sybase says, on the next query: ct_command(): user api layer: external error: This routine cannot be called while results are pending for a command that has been sent to the server. Which happens because we never got to cancel the previous result set. How about running the conversions in a try/except, for safety, like: try: if type(v) is TupleType: v=apply(converters[t], v) except: cm.ct_cancel(sy_occ.CS_CANCEL_ALL) raise Error("Results field conversion error: converter=%s, v=%s" % \ (str(converters[t]), str(v))) I don't think there is anything else, but anything that might throw an exception in the error processing loop should also probably be wrapped to call ct_cancel so that the command structure is ready to go on the next call. Well, that's all. This'll be in the Collector as soon as I can write it, too. -Brian Hooper

Apache? Proxy? PCGI? ZServer?
by J. Atwood 21 Feb '00

21 Feb '00

I have been playing with Zope for months and am a few weeks away from putting a full Zopified site into production. I have a dedicated box so I can do whatever I want in terms of configurations and after reading everything I can get my hands on as possible solutions (I have read http://www.zope.org/Members/guy_davis/install_routes) 1) ZServer Only - This should be the simplest and fastest. The drawback I see is that I will not be able to do SSL or have very good logs to run webserver statistics software on (MKStats, Analog, etc). 2) ZServer Behind Apache + Proxy - This is the second fastest and is relatively easy (have done it once). I get my Apache logs, SSL (I think) but It require SiteAcesss product which could (and seems to) conflict with other products/functionality. 3) Apache, FAST PCGI (Zope.cgi) + ZServer - This is the slowest of them all (a new process for every request) but I most people are using this and allows for all sorts of other goodies that Apache can do (Virtual hosts, logs, SSL, etc). Is there anything I am missing or does anyone have some suggestions/comments on implementations? Thanks, JMA

malformed Acess rule breaks zope
by ethan mindlace fremen 21 Feb '00

21 Feb '00

zopistas I was trying to rewrite the access rule, as per evan's suggestion. I was asking for a slice that wasn't there. Nothing would then come up: any page I tried to go to told me that I had an index error. it wouldn't acknowledge my change that should have fixed it. So i went in with __no_before_traverse__ which worked (whew). Then i tried to edit the method. No dice. Deleting it, however, did work. Just thought I'd mention it, I dunno why it wouldn't fix. ~ethan
