Re: [Zope] Problems adding attribute to custom object
by complaw＠hal-pc.org 02 May '02

Is your new class completely custom, or did you derive it from an existing class (e.g., DTML Document)? Something that has worked for me in the past is to do a search on the set of objects... for obj in context.objectValues('MyClassMetaName'): .. and then use the base class addProperty method to add the additional property. You can also put a try/except block in your code to handle exceptions. Hope that helps. Ron > Hello, > > I'm trying to add a new attribute to all objects of a certain meta_type on > my site.

You'll find "The Zope Book" as free download on www.zope.org. It's a bit outdated (doesn't provide enough infos on Page Templates), and not enough code for my taste. Otherwise, you could order the following books: - Zope Bible, Scott Robertson, Michael Bernstein - Zope , Jerry Spicklemire, Steve Spicklemire, Kevin Friedly, Kim Brand, New Riders; ISBN: 0735711100 Evh.

Still Plagued With Date Formatting Bug in Text Field
by Dan Shafer 02 May '02

02 May '02

I asked this question about 10 days or so ago but I haven't gotten (or at least seen) an answer. I have looked for the answer in Zope docs until my eyes bleed and I just can't figure this out. I have a text field called start_date. I set its default value to today's date by setting its value to (_DateTime().strftime("%b. %d, %Y")) The date shows up in the field, but only the first item of the formatted string displays. In this example, the field contains "Apr." and that's it. Now if I set the default value of a textarea to the same exact value, the date displays correctly. Anybody have *any* idea what in the world is going on here?

python scripts
by Ian! 02 May '02

02 May '02

I am having a very hard time writing python scripts for zope. I don't know which objects do what, and I can't find out where to look up the relevant documentation. I brought this up in an earlier post to the list, but I didn't get a response. I've read through the zope book (at http://www.zope.org/Documentation/ZopeBook/contents ), but it doesn't really cover what I'm looking for - it doesn't really seem to be a guide to writing scripts. The Zope API reference seems to be the reference for people who are developing products or external methods for zope, because all of those modules can't imported from within a python script under zope, even though it seems like stuff I would want to use. http://www.zope.org/Documentation/ZopeBook/AppendixB.stx The Zope help from within the zope management interface contains the same API reference, as well as some other stuff that (as far as I can tell) isn't what I'm looking for. I want to get the current CMF member and change some of it's extra data attributes (attributes which I added with the management interface portal_memberdata) - I don't know how to do this, but more importantly I don't know where to look up how to do it. Can anyone help me out? Sorry for being such a lost newbie =)

products/module search
by Dirk Datzert 02 May '02

02 May '02

Hi, I'm looking for a product or python-modul, which does one or more of the following steps: 1. save an external url in the properties, with/without check on existance of the url 2. can do a remote-http to this external url 3. strip unwanted tags out ( I think this is stripogram for ) 4. rewrite a-tags on a special role products or python-moduls are welcome :-) Thanks, Dirk

Transaction status codes in the ZODB?
by Jean Jordaan 02 May '02

02 May '02

Hi all. When I run 'fsrecover.py' from Zope 2.5.1b1 (source release, python 2.1, linux2) on my Data.fs, I get 710888 errors like:: __main__.ErrorFound: invalid status, ^@, at 23141234 This is output by the following in 'fsrecover.py':: if status not in ' up': error('invalid status, %s, at %s', status, pos) Where are the status codes documented? How do they get set to invalid values? From FileStorage.py I can make some guesses: 'u' == undone 'c' == checkpoint ' ' == dunno? status=packing and 'p' or ' ' But how/where does status get assigned values such as ^@ (ascii value zero)? The returned codes are: ^@, ^F, , ^M, ^R, ^_, %, +, 7, <, @, D, T, ^, k, {, ~, ^?, <8E>, <92>, <95>, <96>, <98>, <9A>, <A9>, <AA>, <AD>, <B4>, <B7>, <C6>, <CA>, <CD>, <DF>, <E3>, <E7>, <E9>, <EA>, <FA> for what that's worth .. -- Jean Jordaan Upfront Systems http://www.upfrontsystems.co.za

RESPONSE.redirect and 301
by Ragnar Beer 02 May '02

02 May '02

Howdy, as far as I can see RESPONSE.redirect sends a '302 Moved Temporarily' status in the header but I need to send a '301 Moved Permanently'. What do I have to do to send the latter status? Ragnar

Zope+Python source-code security
by Pawel Lewicki 02 May '02

02 May '02

Hallo, I was asked to make a web-application that seems to be perfect to be built in Zope and Python. And it is also the great opportunity to get to know the second one :) But the main issue is the security of the source-code. I was browsing the archive and haven't found yes/no answer if it is possible. There are a few security layers: 1. Zope management (I suppose the easiest) 2. Data.fs (Can you pull the stored objects and browse externally?) 3. Secure encryption of external Python modules and methods. If at least one of 1-2/3 elements are possible to protect it might be enough as the part of business logic would be put there. In my case the licensing issue is not a problem. The problem is how to protect the developed solution not to be copied and modified by a "naughty" customer. Unfortunately the application would have to be running on his server. How to convince my boss and myself that Zope is the best solution? Or maybe it is not? :( Pawel Lewicki P.S. Please copy the answer to my address as I have the-whole-day-subscription.
