RESPONSE.Write question
by Small Business Services 16 Sep '03

16 Sep '03

I have been trying to get a test routine working that uses RESPONSE.write... without success: Here is the dtml code I have been using: <dtml-call "RESPONSE.setHeader('Transfer-Encoding', 'chunked')"> <dtml-call "RESPONSE.setHeader('Content-Type', 'text/plain')"> <dtml-call "RESPONSE.write('Starting')"> <dtml-call "wait(5)"> <dtml-call "RESPONSE.setHeader('Transfer-Encoding', 'chunked')"> <dtml-call "RESPONSE.setHeader('Content-Type', 'text/plain')"> <dtml-call "RESPONSE.write('\n\nDone')"> The 'wait' routine is a simple external method: import time def wait(self, secs): time.sleep(secs) return What I expected to see was the word 'Started' displayed in my browser, followed by a 5 second delay, and then see the word 'Done' displayed. What I get is a 5 second delay and then both 'Started' and 'Done" appear at the same time. Any ideas as to what I am doing wrong? Thanks for the help, Jonathan

Custom Method to edit PythonScript
by Christoph Landwehr 16 Sep '03

16 Sep '03

Hi, I would like create a custom DTML-Method to edit a python-script within Zope. The reason for this is that I would like to be able to control in certain ways so I don't want to use "ZPythonScriptHTML_editForm". The user must not be able to change the whole script but only parts I let him see. Something like the 'manage_edit' object of DTML-Methods is (more or less) what I need. The result would be a web-form that lets the user edit some parts of the script body, the parameter and some aditional python code is added by a script/method. (I hope this makes sense ...) I am trying understand how the "PythonScript.py" does things but do to my limited knowledge (Zope-Newbie) I get stuck. My idea was to use the read() function to read the body into my custom form an write it back with the write() function. But doing this I don't use the nifty code-checking feature which I would like to use. Could someone please give me a hint if I am totally off-track? Regards Christoph

zope zen needed...
by Erik Myllymaki 16 Sep '03

16 Sep '03

I have a fairly large intranet site built on Zope. At first it mainly generated reports, but it is starting to be more of a web application then a reporting tool and I am thinking I need to make some decisions now about design. Eventually, I would like my users to be able to access the underlying services with a client other than a web browser. Do I carry on as I am and then build a client that accesses the zope objects via XMLRPC, or do I start making an external python API that I can then access through Zope or my other client(PyQT gui, PyGTK gui, etc.), or... Any advice appreciated.

Re: [Zope] Zope hangs on string compared to '##'

The loop is testing the contents of variable 'i' and you don't change 'i' inside it, so the loop never exits. Try using "if i..." instead of "while i..." Test your script standalone, using a python debugger like Pythonwin or IDLE, and once it works OK upload it into Zope. Gabriel Genellina Softlab SRL

All too true. ;) I certainly don't know why I was able to do an "import _mysql.pyd" and have it work w/o issues in the interpreter. I'm still so new to python and zope that I just don't have the experience to know where to look for explanations yet. > > > Which interpreter? Zope's Py2.2 or your Py2.3? > > > > Zope's Py2.2.

I know. You have to take these things on a gradient. Sometimes checking to make sure the power is actually on is a good first step. ;) So no offense taken. > I would try connecting using odbc.

When I first looked at ODBC DA's for Zope, there were some links but they all linked to commercial packages I thought. And while I certainly don't have any aversion to paying for what I get, right now I'm developing on a strict budget and an ODBC connector wasn't allocated for. It would just be a hassle at this point to PO for one, since that basically stops the development process right now. I'd also certainly like to stay with native DAs where applicable. For the time being, I'm inclined to comment out the original line in ZMySQLDA that is causing the problems (calling the attribute of server_capabilities) and setting it to zero. It's for testing for transactions, which I'm not really doing at the moment, so perhaps I can survive. If anyone has a real solution, however, please speak up! I'm curious, do most people install the python.org python 2.3, and then install/compile Zope from source on Windows platforms? I'd certainly like to go with the most tested means. I use source on FreeBSD and OpenBSD. I use precompiled for Debian and MacOS X, as well as Windows. What is the norm here? Thanks, -j -- Joseph F. Dries III

Registering people in CMF as "Guests"
by BZ 15 Sep '03

15 Sep '03

I have a couple of CMF sites and really love it (reeeeeeeeally I do), but I have a new project where I need to have people be able to register as a "Guest" (different role) or as a "Member" (the role register does now). I poked around some of the scripts but I cannot seem to find anything that shows me what role they get out of the box or where to change that. Anyone done this? Probably something darn simple I am missing. Thanks, BZ

Dear All, Today I have installed RedHat9.0 and zope-2.6.2b3 and copied my Data.fs file from RedHat8.0, Zope-2.6.1b1. but it is giving the following ERROR ERROR: Zope has encountered an error while publishing this resource. Error Type: AttributeError Error Value: __getitem__ Location: /LACorp/Images/manage_workspace What might be the reason. In zope-2.6.2b3, Zserver also installed where as in Zope-2.6.1b1 there was a separate RPM for Zserver. I will be really looking forward for your suggestions -- Thanks & Regards Praveen Kumar SoftPro Systems Ltd

It is same code (with different name)as User agent sniffer from ZopeLabs tip at www.zopelabs.com\cookbook\990728167\, but here are no note about "HUSER" too. So I think that it is undocumented system call (see to date of this tip), but it seems that no-no.: Re: Improvements by ruckc - 2001-07-17 I modified it for versioning in MSIE, ms3, ms4, ms5, ms6. Sorry for the lack of formatting. def whichBrowser(self, ident): if ( (string.find(ident, 'MSIE') == -1) and (string.find(ident, 'Mozilla') >= 0 ) ): if ( (string.find(ident, 'Gecko') > -1 )) : ident = 'nn6' else: ident = 'nn4' elif (string.find(ident, 'MSIE') >= 0): ident = 'ms' thestr=int(HUSER[ind+4] + HUSER[ind+5]) if(thestr >= 3): ver = 3 elif(thestr >= 4): ver = 4 elif(thestr >= 5): ver = 5 elif(thestr >= 6): ver = 6 if(ver) ident = ident+str(ver) else: ident = 'unknown' return ident I was make little tweak: #thestr=int(HUSER[ind+4] + HUSER[ind+5]) thestr=4 It works in Zope, but browser (MSIE4) give me JS errors that makes pages not usable. Does original code for somebody works? > Upgrade to Zope 2.6.2 as soon as you can. Tracebacks (for ZPT, but not > DTML) will become much more readable. I have lot of changes in sources of my 2.5.1 to handle correctly windows-1250 codepage at all situations. Some code is taken from Zope 2.6.2 (STX handling + some mods), so upgrade would be really painfull. Regards, JL.
