Meaning of sequence-index-{variable}
by Luciano Ramalho 29 Apr '03

29 Apr '03

I'm writing a Zope Quick Reference covering DTML and ZPT, and I am stuck trying to figure out the meaning and use of this variable, one of the many available inside a dtml-in loop. All editions of the Zope Book (and every other Zope book I know about) pretty much say the same thing: sequence-index-{variable}: The index of a variable of the current item. You are supposed to replace {variable} with some attribute of your current item. I've tried that with no success (although I've managed to test every other documented sequence-* variable). You can check the official docs here (but they haven't helped me): http://www.zope.org/Documentation/Books/ZopeBook/2_6Edition/ AppendixA.stx Reading the source seemed non-trivial in this case, so I decided to ask after a while (the only relevant module in Zope 2.6.1 seems to be DocumentTemplate/DT_InSV.py). TIA for any help! -- Luciano PS. I've posted this in zope(a)zope.org a few days ago with no reply so far

bug: fmt=structured-txt and unicode
by Oliver Bleutgen 28 Apr '03

28 Apr '03

Hi, when combining localizer and structured text, I found the following quirk (Zope 2.6.1): Rendering an unicode string with <dtml-var unicodestring fmt=structured-text> gives an attribute error with meta_type in Module DocumentTemplate.DT_Var, line 407, in structured_text. A quick glance to the source show the following lines to be the cuplrit: if isinstance(v,StringType): txt = v elif aq_base(v).meta_type in ['DTML Document','DTML Method']: txt = aq_base(v).read_raw() else: txt = str(v) Obviously, this fails. Workaround: Use <dtml-var "_.str(unicodestring)" fmt=structured-txt">, works at least for me, though I don't have real exotic unicode strings. Should I stick it in the collector? I didn't find this error there. cheers, oliver

Zope 2.7 configuration changes: how to run unittests?
by Yuppie 27 Apr '03

27 Apr '03

Hi! Seems this change influences the way how to run unittests: http://cvs.zope.org/Zope/lib/python/Zope/App/startup.py.diff?r1=1.5&r2=1.6 Before this change, I was able to run single tests by adding: - lib/python to sys.path - Zope.startup() to the unittest Now I get this error: Traceback (most recent call last): File "testMyModule.py", line 4, in ? Zope.startup() File "/Zope27/lib/python/Zope/__init__.py", line 46, in startup _startup() File "/Zope27/lib/python/Zope/App/startup.py", line 56, in startup name = config.db_mount_tab['/'] AttributeError: DefaultConfiguration instance has no attribute 'db_mount_tab' Is this a bug or need I an other setup for running tests? TIA, Yuppie

Curious Problem
by stuffduff 25 Apr '03

25 Apr '03

Hi, I have a python external method which reads from an external database, unpickles a class object, and concatenates some of the object's properties into a string which is returned by the external method. The class definition is included in the module. When I run it from the linux prompt in the Extensions directory it behaves exactly as it should. The class is successfully unpickled, the properties are read and the string is returned. However, when I set it up as an external method and call it I get the infamous: Error Type: SystemError Error Value: Failed to import class MyObject from module __main__ >From my perspective Zope should be 'blissfully unaware' of the existence of the class or the instantiation of the object. Since the object is only accessed in the external method, the module contains the class definition, and only a string is returned, why is this happening? What am I missing here? Platform: Red Hat 7.3, Python 2.1.3, Zope 2.51 Curious, Sean

Cookie Crumbler ignores HTTP HEAD?
by Brent M Hendricks 25 Apr '03

25 Apr '03

I see in the code for CookieCrumbler.modifyRequest() that it disables cookies if the HTTP method is not GET, PUT, or POST. Specifically this means that it won't accepct cookie auth for HEAD requests. This is causing problems on my site for users with some browsers. Apparently some browsers (recent Mozillas, maybe others) send a HEAD request when the user right-clicks a link and selects "Save link target as" (presumably to gather information before starting the download). So any links that are restricted to authenticated users have the strange behavior that users can left-click and view the file directly, but if they right-click instead they get the Zope Basic auth dialog. Not at all the desired behavior :) Is there a particular reason why HEAD was omitted from the list in modifyRequest()? Could it be added in?

Form action has no effect
by Ross Boylan 23 Apr '03

23 Apr '03

I had a Zope product that was working OK about a year ago. Now it's not. It seems the form action is not having any effect when I click on the button in the interface. As far as I can tell, the action is never called. I have tried this with Zope 2.4.3, which I think is the same version I ran before, and a fresh install of 2.6.1. One reason for the install was that I moved the entire application directory to a new drive in between, and I thought this might have caused some problems (I manually edited the paths I found). I also extended the app, but not in a way having any connection with the display of the form or action on it that I can see. I'm under MS Win 2k. When I type method calls directly into the browser (Mozilla) I call into the method or get a traceback if the name isn't recognized. But when I hit the action button on the form, I get no change at all except sometimes the URL gets the function arguments, e.g., http://localhost:8080/DSA/DSASync/DSASync/index_html?ignoreBlanks=ignore+bl… where the part from the ? on is new. (Not all tests have the DSASync/DSASync stutter). The dtml form is, in the relevant part: <form action="doddddCompare" method="POST"> <label>Ignore Empty Fields? <input type="checkbox" name="ignoreBlanks" value="ignore blanks" checked> </label><BR> <label>Keys <input type="text" name="key1" value="DSAID"> <input type="text" name="key2"> </label><BR> <input type="SUBMIT" value="compute differences"> </form> When I hit the form's button, I get no traceback that dodddCompare isn't found, and when I enter the real name (doCompare) I do not end up in the relevant method. I have verified that altering other text effects the form, so I am editing the right file and it is being picked up. The other odd thing is that I'm doing this as the root user created at Zope system creation. I thought such users could only create other users, but I'm able to create my object too. I've tried creating another user, but haven't been able to get past permission problems with it. The object statements that gets the form is index_html in the excerpt from the class def below: security = ClassSecurityInfo() security.declareObjectPublic() # added this to try to make things work # never was sure if this needed security # but I can see the form, so I'm OK, right? index_html = HTMLFile("diff", globals()) # here's the method that I'm trying to invoke security.declareProtected('View', 'doCompare') def doCompare(self, ignoreBlanks = None, key1="DSAID", key2=None, RESPONSE = None): # print statements in here never produce output # debug statements never induce a halt I would really appreciate any help, even advice on how to debug this.

What do we want in the way of Zope binary distributions?
by Chris McDonough 22 Apr '03

22 Apr '03

Hi, With the new Zope 2.7 install and configuration stuff (currently on the Zope trunk), ZC needs to redo its mechanisms for Zope binary distribution. Currently, ZC distributes binaries for Win32, Linux, and Solaris on Zope.org. The Linux and Solaris distributions are in the form of a tarball containing binaries. The Win32 distribution contains an executable installer generated by WISE. I'd like to propose that ZC drops the "generic" Linux binary distribution in favor of an RPM distribution that would be "guaranteed" to run on the latest Red Hat release or the one before it, but might also work on Mandrake, etc. It's getting a bit scary to try to distribute a "generic" Linux binary release (who knows what's different about each?), and we really don't have the resources to do a functional test of the binary release on every Linux platform. Additionally, most Linux distributions typically come with all the required tools to compile Zope from source, and compiling Zope from source is now a matter of 'configure; make; make install'. If people don't want to do this, they can install the RPM or their distribution's repackaging of Zope (ala Debian). I also propose we drop the Solaris binary distribution in favor of providing instructions to Solaris folks about how to compile and install the source package. This might be the most contentious proposal: I really have no idea how many people use the Solaris binary distro. The Win32 binary release should likely stay much like it is. I'm not sure about the "upgrade" release packages. Does anybody use these? Comments? - C
