Editing p2.py
by TANNERT,CARSTEN (HP-Germany,ex1) 12 May '03

Hi everybody, I have a short question to you. Is it possible to edit the z2.py script while zope is running, or do I have to stop and restart zope, which would be the service in my case. Thanks in advance for your help. Greetings!!!

RE: [Zope] GET vs. POST
by Passin, Tom 12 May '03

[Dennis Allison] > > How do you transfer information via post when using > REQUEST['RESPONSE'].redirect? > > How do you get Zope to use POST as its default rather than GET? > Hmm, methinks you do not have a clear idea of how these things work. The choice of POST vs GET is not up to Zope per se. It is up to the User Agent, which in practice means it is up to the design of the web page itself. There is no Zope "default". If you want to redirect to a new page and pass some information to the redirected page while you do so, you would give the information to the page template via (typically) REQUEST variables (which you can set during Zope processing) - or other Zope variables - so that the DTML or ZPT that builds the redirected page can include the data into the page. Sometimes the data ends up populating visible or hidden fields in a form, sometimes you decide to apply it in other ways. At this level, neither GET nor POST is involved, since it would happen before the page is built and sent back to the browser. If this is not helpful enough, then give us a few (simplified and clear) scenarios tha trouble you, and maybe we can help clarify and simplify. Cheers, Tom P

WARNING: Packing is dangerous!!! (zope <= 2.6.1)
by Paul Winkler 12 May '03

12 May '03

Sorry for the caps in the subject, but it seems this bug is not nearly well publicized enough.* People keep stumbling onto this bug on their own and writing to the list about it. In Zope 2.6.1, 2.6.0, and probably 2.5.x at least: Packing a FileStorage (Data.fs) can lead to some loss of data. http://collector.zope.org/Zope/875 In addition, the "fsrecover.py" script that ships with Zope 2.6.1 is broken - it (often? always?) produces a nearly-empty Data.fs. If you need it, use fsrecover.py from CVS or from Zope 2.6.0. Considering how much of the existing documentation recommends frequent packing to maintain a healthy Data.fs, I think it would be advisable for Zope corp. to take steps to alert users to this very serious problem. Irrecoverable data loss is the kind of thing that ruins software reputation. Maybe a news item on zope.org? In addition, I think it's a critical enough problem that when a solution is found, there should be published hotfixes for 2.6.1 and 2.6.0 at least. -- Paul Winkler home: http://www.slinkp.com "Muppet Labs, where the future is made - today!"

Guess what? namespace issues!
by jwsacksteder＠ramprecision.com 12 May '03

I have two DTML methods and a one ZSQL method in a folder. I am apparently misunderstanding how to access the ZSQL method. The top-level DTML method contains references in the following form: <dtml-var expr="show_detail(machine='D340')"> The show_detail DTML method exists to wrap the ZSQL method and convert to a human readable form. It currently looks like this: <dtml-in expr="get_sum_sql(_)"> <dtml-var subtotal null="0"> <dtml-else> 0 </dtml-in> The ZSQL method accepts a single parameter called 'machine'. For each parameter, it will produce a single result. This makes sense to me. Unhappily, it does not work. It produces the following error: Error Type: NameError Error Value: global name 'get_sum_sql' is not defined I'm sure I'm missing the obvious here...

ZCatalog to Search MySQL field?
by John P. Withers 12 May '03

12 May '03

All, I am just getting my feet under me with Zope and trying to figure out how to get the following functionality. I have a MySQL table with a notes field that stores, as you might expect, notes about a record. I need to get a reasonably functional search capability for this field (boolean AND and NOT at least) that returns the serialnumber field of the record it is attached to. Upgrading to the latest version of MySQL isn't optimal. The Text Index capabilities of the ZCatalog object seem to be perfect for my needs, but I can't figure out how I would implement the ZCatalog object to search the notes field through my ZSQL object. I could write a script to get the functionality I want, but don't want to reinvent the wheel and would also like to grok how the ZCatalog works anyway. Is this doable and can someone either tell me how to do it or point me to documentation that would be readable by a capable novice? Thank you for your time. John P. Withers

passing information to a rendered ZPT from python
by martin f krafft 11 May '03

11 May '03

i have a python script that ends with return getattr(context, 'a_page_template', None).render() this works like a charm, rendering the page template and outputting it as if the python script produced it. however, i am not sure how i can pass some information (e.g. a username) to the page template. so far i have been using the REQUEST object, but that's an ugly hack, and it also doesn't work (see previous post), so i'd like to do it right. how? -- martin; (greetings from the heart of the sun.) \____ echo mailto: !#^."<*>"|tr "<*> mailto:" net@madduck keyserver problems? http://keyserver.kjsl.com/~jharris/keyserver.html get my key here: http://madduck.net/me/gpg/publickey "when faced with a new problem, the wise algorithmist will first attempt to classify it as np-complete. this will avoid many tears and tantrums as algorithm after algorithm fails." -- g. niruta

recursive security changes
by martin f krafft 11 May '03

11 May '03

are there any products or tools out there that i can use to manage the security settings of a rather bug site? i know that acquisition takes care of most, but one thing i would like to do at first is to reset all permissions of all children of the root folder to 'acquire' and nothing more, and then gradually go from there... any tips appreciated! -- martin; (greetings from the heart of the sun.) \____ echo mailto: !#^."<*>"|tr "<*> mailto:" net@madduck keyserver problems? http://keyserver.kjsl.com/~jharris/keyserver.html get my key here: http://madduck.net/me/gpg/publickey the dump was so full that it had to refuse more refuse.

Problem with send in ZClass
by Jamie White 11 May '03

11 May '03

I built a ZClass and I want to send an email if a certain property is missing, the script I am using to try to do this looks like this # Send an Email if draft == None: body="Content Provider " + AUTHENTICATED_USER.getUserName() + " has completed work on. Please review for publishing" context.MailHost.send(body, mto="jamie(a)brobus.net", mfrom="zope(a)brobus.net", subject="Content Done", encode=None) return body else: return "No Message" It when I test it alone, but for some reason when it is in the zclass it says I am not allowed to send in this context. I changed the proxy role on the script to manager but that didn't help. Jamie jamie(a)brobus.net
