external methods
by Arenz, Ralph 17 Oct '01

17 Oct '01

Hi, i' am using external methods to do something on the filesystem.So i make an external method for the entry-function. This works fine,so far. The module which is containing the function imports several other modules which i placed in <zope>/lib/python> directory. My problem is that changes to imported modules takes no effect. What have i to do to tell Zope that the imported modules has changed ? A simple buttonclick in the Zope manage screen won't do. Equally, compiling the imported method to bytecode takes no effect. Changes in the function or module which is connected via "external method" to zope are approved after a buttonclick on "edit" in zope. has someone an idee ? regards Ralph

Form records not behaving as I would expect
by Kirk Strauser 17 Oct '01

17 Oct '01

I am trying to use the 'records' directive to combine input data from a form into records that I can insert into an SQL table using this method: ######################################## Z SQL Method: demoSet Arguments: locationid demoname update demomap set locationid=<dtml-sqlvar locationid type="int">, demoname=<dtml-sqlvar demoname type="string"> ######################################## The form I'm using is this: ######################################## <dtml-var standard_html_header> <dtml-if action> <br>You submitted some values! <dtml-in demolist> <dtml-set locationid=locationid> <dtml-set demoname=demoname> <dtml-call demoSet> </dtml-in> </dtml-if> <form action="<dtml-var URL>" method="GET"> <table border="<dtml-var table_border>"> <dtml-in demoGetAll> <tr> <td valign="top"><dtml-var locationname>:</td> <td> <input type="hidden" name="demolist.locationid:int:records:ignore_empty" value="<dtml-var locationid>"> <input type="text" name="demolist.demoname:string:records" value="<dtml-var demoname>" size="70"> <br><a href="<dtml-var demoname>">Test link</a> </td> </tr> </dtml-in> <tr> <td colspan="2" align="center"> <input type="submit" name="action" value="Make these changes"> </td> </tr> </table> </form> <dtml-var standard_html_footer> ######################################## The problem I'm experiencing is that the <dtml-in demolist> block in the DTML document above fails unless I have the seemingly-redundant dtml-set tags at the start of the block. Specifically, I get a "Missing input variable, locationid" message and some traceback information, which I haven't included here but can reproduce if needed. Now, if I replace the lines <dtml-set locationid=locationid> <dtml-set demoname=demoname> <dtml-call demoSet> with <br><dtml-var locationid> <br><dtml-var demoname> the the script cheerfully outputs the expected values. I'm stumped. Why can I display those value but not insert them with an SQL query? I've read several HOWTOs that assert that I should only need to use: <dtml-in demolist> <dtml-call demoSet> </dtml-in> and be done with it. I appreciate any insight into my problem. I'm coming from a C++/Java/Perl/PHP background and haven't quite gotten into the Zope way of doing things yet, although my Zope Book should be arriving in the next day or so. Many advance thanks for a newbie! -- Kirk Strauser

by Antonio Beamud Montero 17 Oct '01

Hello all: I'm a new Zope developer and I a bit confused with the Plugins Model... I have created a Plugin container and a Plugin.

Hi. I have an object, a form, that is part of a page with lots of other interface around it. Can anyone suggest a way to print (to a printer) an object (the form object only) on the page? Thanks.

RE: OT: using 'patch' with wildcards

Oleg Broytmann wrote: > > > patch -p0 < ../Patches/* > > Wrong. Shell will expand it as > > patch -p0 < ../Patches/Patch1 ../Patches/Patch2 > > and oops... shell syntax error. Indeed, you're right. So this:: patch -p0 < ../Patches/* will only work if there is only one patch. For more than one patch, one could do this:: find ../Patches/ -exec patch -p0 -i \{\} \; but that's a long way from the ZenFromZopeCoders page .. Which makes me wonder again if Evan uses a different version of 'patch'? Jean

OT: using 'patch' with wildcards
by Jean Jordaan 17 Oct '01

17 Oct '01

Hi all I'm trying to learn what I can about using CVS with Zope, and I'm tripping over a line in Steve Alexander's ZenFromZopeCoders [1] page. In the section: "How Evan keeps his own personal patched Zope up to date" there is the command:: patch -p0 ../Patches/* What version of 'patch' is this? Mine is patch 2.5.4 [2], and 'patch --help' says: Usage: patch [OPTION]... [ORIGFILE [PATCHFILE]] In other words, ORIGFILE is mandatory. So Evan's idiom doesn't work here. And if I have to specify the ORIGFILE on the commandline, then a wildcarded PATCHFILE doesn't make sense. So how do I automatically apply all the patches in a directory? Please tell me where to RTFM? Regards, Jean .. [1] http://dev.zope.org/CVS/ZenFromZopeCoders?pp=1 .. [2] Full output:: $ patch --version patch 2.5.4 Copyright 1984-1988 Larry Wall Copyright 1989-1999 Free Software Foundation, Inc. [...] written by Larry Wall and Paul Eggert

"evaluating" a REQUEST Parameter to be passed to a dtml-var
by Doyon, Jean-Francois 17 Oct '01

17 Oct '01

Hello, Sorry, but I'm new at this :) The problem is simple, I want to call a dtml-var using a name (object) provided by the URL So for instance if the url is: http://host/cmf?document=main_english I want <dtml-var main_english fmt="structured-text"> to work properly. Of course the problem I'm having right now is that the parameter value is being passed as a string instead of being eval'ed ... So instead of the contents of "main_english" I get the STRING "main_english"! Unfortunately (Although for good reason) python's "eval" is not available ... So how do I do it? Thanks!
