Hmm.. This is not as inconsistent and illogical as you think. Your DTML page is compiled into a hierarchy of objects, speeding up rendering of the page when called. Most attributes are static, which helps. Only those attributes that need to be dynamic, are really so, just to help this along. Attributes that allow expressions are an exception, not a rule. -- Martijn Pieters, Web Developer | Antraciet http://www.antraciet.nl | Tel: +31-35-7502100 Fax: +31-35-7502111 | mailto:mj@antraciet.nl http://www.antraciet.nl/~mj | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 ------------------------------------------

Passing query strings in trees
by Jim Cain 07 Oct '99

07 Oct '99

All, I have a Zope tree structure that requires a query variable to be passed to it. The first time through, I can pass it on the http request with no problem: http://www.mgmt-inc.com/some_object?variable=value But this query string is not included in the [+] and [-] links to expand/contract the tree so that I can pass it on to the next rendering of this object. How do I do this? Thanks for the help, Jim ____________ Jim Cain, System Administrator ___ / ________ \ http://jec.mgmt-inc.com / / / / ______ \ \ _________ _______ _________ __/ /__ / / / __ \ \ \ / _ _ \ / ___ \ / _ _ \/_ ___/ / / / /_/ / / // // // // /__/ // // // / / /___ \ \ \___,_ \/ //__//__//__/ \____ //__//__//__/ \_____/, inc. \ \______\____/ _____/ / \_______/ \______/ http://www.mgmt-inc.com

Broken or fixed?: Zclass, manage_changeProperties or zclass tute
by cameron＠mail.earth.monash.edu.au 07 Oct '99

07 Oct '99

Summary: -------- instance.manage_changeProperties is broken (with no ERROR!) or changed to the more 'obvious': instance.propertysheets.cd_info.manage_changeProperties The tutorial on zclasses doesnt work either the class or the documentation needs a change. Longer: ------- I have been trying to get zclass instances to be changed by dtml methods as outlined in the tutorials for a couple of days now with no luck. Now I know why....... zclassinstance.manage_changeProperties({'phone':'666'}) attempts to make the change to the FOLDER containing the zclass instance, not the instance itself. zclassinstance.propertysheets.cd_info.manage_changeProperties({'phone':'1.5'}) works as you would want (it changed the instance value of phone). Is there any reason why manage_changeProperties isnt defined for the namespace of zclassinstance? (This used to work I recall from a few zope's back). (I found this out by adding a phone property to everything on the tree down to my instance and looking at what changed, so I assume the folder is the next thing 'up' that contained manage_changeProperties :). So... ----- I dont know enough Zope internals to know how to fix it. While we are at it, is there doc on the namespace that zope uses for the various dtml things such as foo, "foo" and "_.foo"? Or is it UTSL? cheers, cam -- / `Rev Dr' cameron(a)mail.earth.monash.edu.au skeptic, virtual goth, poly \ < [+61 3] 9905 4881[w] Linux, Unix, python, genetics, nets > \ Earth Science, Monash Uni. http://www.earth.monash.edu.au/~cameron/ / ---------- Random Quote ---------- You ain't learning nothing when you're talking.

permissions weirdness with the tree tag
by Roman Milner 07 Oct '99

07 Oct '99

The short question: Shouldn't a user created in the acl_users folder at the root with Manager be able to do all the things that the user created in ZOPE_ROOT/access? If not, what is the difference? The long explanation: If I create an index_html in / that just does:  <dtml-tree> <dtml-var id> </dtml-tree>  It will pop up a login when I go to it. If I log in as the user in my access file it works, if I login as the user created in in /acl_users with Manager - it get authorization failed. However, I can go to http://localhost/manage and login with the user in /acl_users and everything seems to work fine (except viewing /index_html.) I've written a product that lets you browse LDAP servers via the tree tag but I can' seem to make it so Anonymous can view the page. Please help! ^Roman

Can't put Zope 2 to work in an AIX 4.1.4. HELP!!!
by Paulo Eduardo Neves 07 Oct '99

07 Oct '99

I've been developing in my personal linux machine in Zope 2, while my production site were still working with Zope 1.10.1. Today was the day to publish some new features. But I couldn't put Zope 2.0.1 to work in an AIX 4.1.4 machine!:-(( Zope spent *minutes* to present the default screen. Couldn't go further. I've already had installed python 1.5.2 (Zope1 was installed with 1.5.1). After linking some configuration files (as told in PLATAFORM/AIX.txt) everything compiled fine, except for some warnings in zlib module. I've deleted the zlib since I already have it with my python. The problem? I run the start script and everything looks fine. When I try to connect server:8080/ the browser contacts the server but no answer. After more than 5 *minutes* zopes default home page appears. If I try to go to the manage page just after a lot of time I get the login dialog. Even after waiting a lot the management screen doesn't appear. When I go to lib/python/ and try to "import Zope" I get : >>> import Zope Traceback (innermost last): File "<stdin>", line 1, in ? File "/web/Zope-2.0.1-src/lib/python/Zope/__init__.py", line 94, in ? import ZODB, ZODB.ZApplication, imp File "/web/Zope-2.0.1-src/lib/python/ZODB/__init__.py", line 85, in ? import sys, ExtensionClass, TimeStamp, cPersistence, Persistence ImportError: from module ExtensionClass.so No such file or directory If I insert the /web/Zope-2.0.1-src/lib/python dir as the first entry in sys.path, module Zope imports. Then I try to get a connection and it fails: >>> import sys >>> sys.path.insert(0, '/web/Zope-2.0.1-src/lib/python') >>> import Zope >>> app = Zope.app() Traceback (innermost last): File "<stdin>", line 1, in ? AttributeError: app >>> I've already tried a lot of things, starting zope with different users. Recompiling, reinstalling, etc.. I'd like any advice. Tips to debug this are welcome. I've already exhausted my possibilities. regards, Desperate Paulo -- Paulo Eduardo Neves maito:neves@email.com

Mime tag not flexible enough
by Jay, Dylan 07 Oct '99

07 Oct '99

I needed the ability to be able to conditionally include attachments to a mail message. Unfortunately the mime tag syntax made this impossible. I've updated it by splitting the tag into two tags. I've submitted it to the bug collector. Anyone have any constructive criticism? Here is an example of my syntax. <dtml-sendmail mailhost=MailHost> To: blah(a)lucent.com From: <dtml-var AUTHENTICATED_USER>@lucent.com Subject: Bug submission: <dtml-var description> <dtml-mime> <dtml-boundary type="'text/plain'" encode="'7bit'"> <dtml-var mailContent> </dtml-boundary> <dtml-with event_log><dtml-if filename><dtml-boundary name=filename description="'Event Log'"><dtml-var read></dtml-boundary></dtml-if></dtml-with> <dtml-with comm_mon><dtml-if filename><dtml-boundary name=filename description="'Communication Monitor'"><dtml-var read></dtml-boundary></dtml-if></dtml-with> <dtml-with archive><dtml-if filename><dtml-boundary name=filename description="'Archive'"><dtml-var read></dtml-boundary></dtml-if></dtml-with> </dtml-mime> </dtml-sendmail> Here is the code from my revise MIMETag.py file from DocumentTemplate.DT_Util import * from DocumentTemplate.DT_String import String from DocumentTemplate.DT_Let import Let, parse_let_params from MimeWriter import MimeWriter from cStringIO import StringIO import string, mimetools MIMEError = "MIME Tag Error" class MIMETag: ''' ''' name='mime' blockContinuations=() encode=None def __init__(self, blocks): tname, args, section = blocks[0] args = parse_params(args, name=None) has_key=args.has_key self.section = section.blocks def render(self, md): contents=[] mw = MimeWriter(StringIO()) outer = mw.startmultipartbody('mixed') d={}; md._push(d) try: d['mime-writer']= mw outer.write(render_blocks(self.section, md)) mw.lastpart() outer.seek(0) return outer.read() finally: md._pop(1) __call__=render class BOUNDARYTag: ''' ''' name='boundary' blockContinuations=() encode=None def __init__(self, blocks): tname, args, section = blocks[0] self.__name__ = args self.section = section.blocks self.args = args = parse_let_params(args) for i in range(len(args)): name,expr = args[i] if expr[:1]=='"' and expr[-1:]=='"' and len(expr) > 1: # expr shorthand expr=expr[1:-1] try: args[i] = name, (1,Eval(expr, expr_globals).eval) except SyntaxError, v: m,(huh,l,c,src) = v raise ParseError, ( '<strong>Expression (Python) Syntax error</strong>:' '\n<pre>\n%s\n</pre>\n' % v[0], 'boundary') def render(self, md): contents=[] try: mw = md['mime-writer'].nextpart() except: mw = MimeWrite() args = {} # evaluate any expressions for name,expr in self.args: try: isExpr, expr = expr except: isExpr = 0 if not isExpr: args[name]=md[expr] else: args[name]=expr(md) has_key=args.has_key if has_key('type'): type = args['type'] else: type = 'application/octet-stream' if has_key('disposition'): disposition = args['disposition'] else: disposition = '' if has_key('encode'): encode = args['encode'] else: encode = 'base64' if has_key('name'): name = args['name'] else: name = '' if encode not in \ ('base64', 'quoted-printable', 'uuencode', 'x-uuencode', 'uue', 'x-uue', '7bit'): raise MIMEError, ( 'An unsupported encoding was specified in tag') b = self.section if disposition: mw.addheader('Content-Disposition', disposition) if args.has_key('description'): mw.addheader('Content-Description', args['description']) mw.addheader('Content-Transfer-Encoding', encode) if name: plist = [('name', name)] else: plist = [] mfile = mw.startbody(type, plist, 1) output = StringIO() if encode == '7bit': mfile.write(render_blocks(b, md)) else: mimetools.encode(StringIO(render_blocks(b, md)), output, encode) output.seek(0) mfile.write(output.read()) return mfile.read() __call__=render String.commands['mime'] = MIMETag String.commands['boundary'] = BOUNDARYTag

Is there a way of protecting your zope source

07 Oct '99

Hello all, I have an oppurtunity to create a web site for a customer. As far as I know the zope folder I export can be imported into the zope environment at the customer site. But the source will also be accessible. Is there any way of protecting my source code such that the customer will not be able to work on the source. Thanks sathya

Zcatalog confusion
by Geir B Hansen 07 Oct '99

07 Oct '99

I have a Zcatalog called newscatalog in my news-folder to index my news (Zclass). The newsdocs are catalog-aware, and i use reindex-object in the function that makes and modifies them. Still, they do not get cataloged.. Not even when i use the 'update catalog'-button in the catalog management.. - i have to go through the whole 'add items to zcatalog' routine to make my new instances show up in the catalog... Does this have anything to do with my catlog not being in the root folder ??
