Much of the aim of the "Product Developer's Guide" (see http://www.zope.org/Wikis/Docs/ProductDevelopersGuide) is to address the issues you bring up. It's been slow going, although I almost have the security chapter completed. Hopefully this weekend I'll be able to release that chapter. > -----Original Message----- > From: Kapil Thangavelu [mailto:kthangavelu@earthlink.net] > Sent: Thursday, August 17, 2000 11:19 PM > To: Dieter Maurer > Cc: zope(a)zope.org; woessner(a)springer.de; frs(a)lysia.de > Subject: Re: [Zope] [Ann] Another Zope Book > great plan. > redundant no... desparetely needed? yes:) > > my thoughts... > > i've often felt thought that dc and zope cater a bit too much to the > newbie crowd in the sense that the documentation is built around on > touching upon a working knowledge of acquisition and the majority > focuses on dtml. i often felt the need (and perhaps i'll scratch the > itch) for a zope book for python developers. python is easy to learn, > there is no reason zope can't be if it were approached as a collection > of python frameworks. zodb (acqusition, persistence, zcatalog), > medusa(asyncore+orb), document template, security. > > many of the components of zope are very suitable for reuse outside of > zope to a python programmer if the pieces were understood as separate > entities and explained how they worked in synergy to make zope work, i > think there would be many more developers and products for zope. > > as is, you learn piecemeal unless you have the stomach and the time to > go through all the source code. i've learned a bit (still learning) > mainly from the source, but i think most developers are > forced to learn > through trial and error because the docs don't do the > components justice > since they tend to focus on working understanding of zope's framework > from dtml. and in the end they are forced to turn to the source which > can be confusing without knowing the parts of the framework from a > fundamental not a working perspective. > > comments? > > Kapil > > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://lists.zope.org/mailman/listinfo/zope > ** No cross posts or HTML encoding! ** > (Related lists - > http://lists.zope.org/mailman/listinfo/zope-announce > http://lists.zope.org/mailman/listinfo/zope-dev ) >

unable to login with newly created user

Hello all, I'm new to Zope - extreme apologies if this question has already been answered, but I'm simply at wits end here... Linux 2.2.14 Python 1.5.2 Zope 2.2.0 from source wo_pcgi Zserver I simply cannot for the life of me log in as non-superuser. I've installed and unininstalled and re-installed... and read, and re-read the docs but to no avail - I even went so far as to try from scratch on a wholy different computer all together and was met with the exact same issue. After spending plenty of time in the archives for the list and at the zope site's howto's I still have been unsuccessfull in gleaning any help. I must have missed something very simple along the way somewhere. Here, in step by step order, is what I've been doing: log in as superuser access the manage page traverse into the /acl_users folder add a new user correctly set and verify the password attach Manager and Owner roles to user submit the Change button restart Zope clear netscape cache close netscape restart netscape point browser to zope page attempt to login with new user into Manage page... *allways* fail *everytime* with an 'Authorizatin failed' msg ack! What is my feeble little mind not catching onto here? I've ran z2.py with the -D flag and logging, and went through the same steps but nothing at all in these logs provides me with anything remotely usefull... I've ran Zope as both root and nobody, with no change. This is very frustrating, I've been at it for most of the night now. I sure could use a clue... Thanks, Corey

<dtml-tree, the bane of my life :(
by Chris Withers 18 Aug '00

18 Aug '00

Okay, firstly, I notice dtml-tree doesn't support the standard abbreviation: <dtml-TAG "x"> -> <dtml-TAG expr="x"> As the following: <dtml-tree "_.getitem('sequence-item',0)" branches="postingValues"> gives me: Error Type: KeyError Error Value: "_.getitem('sequence-item',0)" nice... Now the one that has me stumped :( Why does the following: <dtml-tree expr="_.getitem('sequence-item',0)" branches="postingValues"> Give me: Error Type: NameError Error Value: _ This is all in 2.1.6... cheers, Chris PS: The traceback for the last one: Traceback (innermost last): File E:\Zope\2179E4~1.6\lib\python\ZPublisher\Publish.py, line 214, in publish_module File E:\Zope\2179E4~1.6\lib\python\ZPublisher\Publish.py, line 179, in publish File E:\Zope\2179E4~1.6\lib\python\Zope\__init__.py, line 202, in zpublisher_exception_hook (Object: ElementWithAttributes) File E:\Zope\2179E4~1.6\lib\python\ZPublisher\Publish.py, line 165, in publish File E:\Zope\2179E4~1.6\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: manage_postings) File E:\Zope\2179E4~1.6\lib\python\ZPublisher\Publish.py, line 102, in call_object (Object: manage_postings) File E:\Zope\2179E4~1.6\lib\python\App\special_dtml.py, line 120, in __call__ (Object: manage_postings) (Info: E:\Zope\2.1.6\lib\python\Products\Squishdot/Squishdot_manage_postings.dtml) File E:\Zope\2179E4~1.6\lib\python\DocumentTemplate\DT_String.py, line 502, in __call__ (Object: manage_postings) File E:\Zope\2179E4~1.6\lib\python\DocumentTemplate\DT_In.py, line 691, in renderwob (Object: postingValues) File E:\Zope\2179E4~1.6\lib\python\TreeDisplay\TreeTag.py, line 152, in render (Object: a tree tag) File E:\Zope\2179E4~1.6\lib\python\DocumentTemplate\VSEval.py, line 208, in eval (Object: _.getitem('sequence-item',0)) File <string>, line 0, in ?

cutting and pasting large folders
by Jean Jordaan 18 Aug '00

18 Aug '00

Hi Zopers I'm trying to cut and paste (or copy and paste) '/docs' to '/in/docs'. The browser spins for about a minute or two, and then returns "HTTP 500 - Internal server error". Is this because '/docs' is large (about 10 or 15 Mb) (not very large) or because it contains instances of my 'ccDoc' ZClass that doesn't want to be cut-&-pasted? Strangely (well, *I* think it's strange) I can copy everything inside of '/docs' (including a bunch of ccDoc's, a Zcatalog and a Ztopic) and paste them into (a new) '/in/docs' .. but now I have to transfer the properties on '/docs' to '/in/docs' .. or maybe this is a good time to move them to TinyTables. -- Jean Jordaan -- technical writer -- Mosaic Sofware -- Zope 2.1.6 on WinNT and W2K

> Or maybe everyone is quietly happy.... Well, yes :) So, would all of those quietly happy people perhaps give a shout to reassure those of us who are loathe to install all of IIS for the sake of NT domain authentication? -- Jean Jordaan -- technical writer -- Mosaic Sofware -- Zope 2.1.6 on WinNT and W2K

<dtml-with object> calls first?
by Chris Withers 18 Aug '00

18 Aug '00

Hi, Just noticed this: If you do <dtml-with object> where object is something callable, it calls it. That's a bit unpleasant for things like Squishdot Sites which do something (return a list of all their elements) when you call them. So the only way to _really_ do what I thought dtml-with is for was to do <dtml-with "object"> which is sucky to say the least. Comments, anyone? cheers, Chris

Hi Toby > No feedback on this from anyone yet. Well, that doesn't really sound encouraging .. So it looks like the main NT-based authentication for Zope is currently jcNTUserFolder, running as pcgi behind IIS. I'm making an intranet for 100-200 people, with offices on three continents connected via VPN. It would be very cool to be able to delegate all password worries to NT. cheers, -- jean

DCOracle help required
by Alwyn Schoeman 18 Aug '00

18 Aug '00

Hi, Let me explain my situation. The oracle server is version 7.3.4 running on Solaris. I compiled DCOracle 1.3.1b1 on the Sun using the Oracle 7 libraries. With this I can access an Oracle 8.0.5 database running on Linux over the network. Now I want to access the Oracle 7 database from a Linux machine. Only Oracle you can get for Linux is 8, so I'm using 8.1.6. I can get it to compile and installed. But when I do the following to the Oracle 7 database I get: >>> import DCOracle >>> dbc = DCOracle.Connect("ota/ota@ota1") OCI_ERROR at oci_8.c:326 ORA-01005: null password given; logon denied Traceback (innermost last): File "<stdin>", line 1, in ? File "/usr/lib/python1.5/DCOracle/ocidb.py", line 77, in __init__ sc=oci_8.Logon(u,p,s) OracleError: (1005, 'ORA-01005: null password given; logon denied') Can anyone please help me to get this to work... Thank you Alwyn Schoeman

<dtml-else> and 'unexpected end tag'
by Chris Withers 18 Aug '00

18 Aug '00

Squishdot_manage_postings.dtml contains this weird bit of DTML: <dtml-else reviewed> <FONT COLOR="RED">*</FONT> </dtml-else reviewed> Is this a weird bit of syntax that's allowed in DTML or is it a bug in the parser that means this isn't being picked up? If it's a weird bit of syntax, then there's a bug in dtml-in 'cos when you try to wrap the above in a dtml-in, you get that very unhelpful 'unexpected end tag, for tag </dtml-in postingValues>' error. While I'm at it, that error, which you see a lot, is _really_ unhelpful, since it doesnt' actually tell you anything about the real problem ;-) cheers, Chris

The date in Dutch - really last time!
by Steve Alexander 18 Aug '00

18 Aug '00

Ok... this is *really* the last time. I don't know why I was using a regular expression, when string.replace would have done just as well. Here's my final version of the external method. I *promise* I won't change it again. Of course, the simplest version would be from string import replace def D_date(datestring): datestring=replace(datestring, 'Monday', 'Montag') datestring=replace(datestring, 'Tuesday', 'Dienstag') # und so weiter However, this would be slower to execute than using "reduce", as below. ---- from string import replace # you can remove lines where the words are the same in both languages replacements={ 'Monday':'Montag', 'Tuesday':'Dienstag', 'Wednesday':'Mittwoch', 'Thursday':'Donnerstag', 'Friday':'Freitag', 'Saturday':'Samstag', 'Sunday':'Sonntag', 'January':'Januar', 'February':'Februar', 'March':'März', 'April':'April', 'May':'Mai', 'June':'Juni', 'July':'Juli', 'August':'Augustus', 'September':'September', 'October':'Oktober', 'November':'November', 'December':'Dezember' } replace_fns=[] for e,d in replacements.items(): replace_fns.append( eval("lambda x: replace(x, '%s', '%s')" % (e, d))) del replacements def D_date(datestring): return reduce(lambda x,y: y(x), replace_fns, datestring) ---- -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net
