 Well, thanks, but too bad the only FM I've been able to find about Zope are
 those .py files in lib/python/...
 
 I spent a whole day looking for documentation on ZODB internals on zope.org and
 zdp.zope.org, without being able to find anything... how about adding that
 paper to the search engine on zope.org? Is there more documentation like that
 one out there?


a couple actually, not located so that you can find them but they exist

jim fulton's paper from the ipc8 (python conference) is excellent
reading material. 

http://www.zope.org/Members/jim/Info/IPC8/ZODB3News

also the uml models 

http://www.zope.org/Documentation/Developer/Models/ZODB/

and another excellent paper by andrew kuchling on zodb and ZEO

http://starship.python.net/crew/amk/python/writing/zodb-zeo.html

there is also a how-to...

Cheers

[Zope-dev] why is manage_addZSQLMethod unavailable ?

2000-08-18 Thread Hannu Krosing

Why does this work

dtml-call "_['testadd'].manage_addDTMLMethod('MethodId', 'Method
Title','method text')"


While this does not:

dtml-call "_['testadd'].manage_addZSQLMethod('ZSQLID', 'ZSQL Title',
'DB','','select * from data')"

Error Type: AttributeError
 Error Value: manage_addZSQLMethod

I studies the Znolk product and found that it uses _setObject directly
instead of 
manage_addZSQLMethod .

I was able to overcome it by defining an  one-line external method:

-
from  Products.ZSQLMethods.SQL import *

def manage_addZSQLMethod(self, sqlId, sqlTitle, connection_id, args, command):
self._setObject(sqlId, SQL(sqlId, sqlTitle, connection_id, args, command)) 
-

but it IMHO the visibility of manage_addDTMLMethod and manage_addZSQLMethod 
_should_ be the same ?

In general there is an inconsistency in adding objects: sometimes you can
use the manage_addYourProduct interface, and sometimes only going through
the addProduct invocation (don't have the whole thing handy here) will do
the trick. This can get very confusing. Wouldn't know if that's the matter
here, though. I think this should be standardized in the interfaces.

[Zope-dev] Re: /, XML, DTML syntaxgeddon

2000-08-18 Thread Evan Simpson

From: Chris Withers [EMAIL PROTECTED]
 I suggested the / thing to Steve who pointed out that
 dtml-/folder/object; is bad XML/SGML and so 'Not a Good thing (tm)'

Yes, well, making DTML compatible with XML is explicitly *not* a current
goal, although having ':' as an alternative separator should make folks who
have to deal with it happy.  In all other naming areas, especially indirect
reference (ie. expr="_['/folder/object']") I much prefer slashes.

 What's this DTML syntaxgeddon then? ;-)
 This sounds like something I'd really be interested in as you can see
 from my ZTL proposal on dev.zope.org.

There are so many ideas for revising DTML that the whole thing ought to be
done as a single large change (the syntaxgeddon) rather than dribbling out
new features and spellings over time.  That can easily make people feel that
they can't keep up with "all these crazy changes".

 However, I'm pretty confident that when  say DTML is a mess right now,
 I'm not far wrong. How can I get involved in the process to try and
 rectify this?

Just keep giving feedback on those proposals.

Cheers,

Evan @ digicool  4-am

[Zope-dev] ZPatterns and Strategies Patterns etc....

2000-08-18 Thread Steve Spicklemire


Hi Folks,

   Well.. I never heard any comments about my last question.. so I
thought I'd try to frame it differently. I just read Coad's book on
Object Models etc.. and I think I pretty well 'grok' it.. at least
enough to be mildly dangerous. ;-) I'm implementing a project with
ZPatterns and I would like to keep a balance between flexibility and
sanity (and of course performance). I've been using 'raw Specialists'
to keep the number of new classes down to a bearable number, but I'm
beginnnig to thing that Zope would behave itself better if I were to
create Product level sub-classes of Specialist instead. I guess I'd
just like to 'hear' what folks think about these different strategies:

at one end of the spectrum:

1) Use ZClasses and 'out of the box' specialists for 90% of the application.
   Make ZClass and only where python is *required*, use external methods.

at the other end of the spectrum:

10) Use full Python products, possibly subclassed from ZPatterns classes
(DataSkin, Specialist etc) and never use ZClasses at all...

and there is the middle ground:

5) Use python products for low level logic. Create overriding methods that 
   can be 'dropped in' at the admin interface level, or in a subclass,
   later to change the behavior (e.g., retrieveItem ). Make ZClass sub-
   classes so that userinterface can be easily modified later, and so
   that persistent propertysheets are easy to add... 

There are problems with each end of this spectrum... 

1) There are still limitations on what you can easily do outside of
   python. PythonMethods are great but they have strict security
   limitations that make them cumbersome in some cases.

   When you want to call a method of an object, that is really a 'DTML/Python Method'
   you need to pass along context so you end up with a lot of:

   dtml-with FooManager

  dtml-let theResult="aMethodOfTheFooManager( )"


  /dtml-let

   /dtml-with

   This seems like a lot of monkey-business just to call a method. Also.. nested
   withs can generate problems with namespace pollution.. and unfortunately 
   performance.

5) Same problems as above when invoking methods that are implemented as 
   DTML/Python Methods.. otherwise.. not too bad.. this is where I'm
   living at the moment. All my DataSkin classes are structured as:

   DataSkin -- myBaseClass - zSubClassableWrapper - ZClass

   My Specialists are just plain old Secialists... (here's the problem..
   should they be Python products so that they can have plain 
   Python methods?

10) Everything is defined in Products... harder to integrate into other apps
   since it's hard to override/change methods without modifying source code on
   the file system. I can't believe everyone is doing it this way.. but then
   I con't believe that folks are pushing and popping namespaces all over 
   the place like I seem to in my app 

Anyway.. thoughts are appreciated.

;-)

thanks,
-steve

In another current project, I'm building a python product that consists

base classes. 


This latter project involves more text processing and python stuff. The
former project involves workflow and flexible presentation.

Re: [Zope-dev] patch for dtml-foo:bar:baz;

2000-08-18 Thread Jon Franz

This may, or may not, break the alternate syntax patch/download @
http://www.zope.org/Members/Coventry/dtml_shortcut
I'll investigate and find out, and release a new dtml_shortcut if needbe.
(I specifically used a colon since it is valid xml) What about using a colon
as the separator, but explicitly give the tag the name dtml-root?
dtml-root foo:bar:childofbar

having a whole tag of type ':' seems weird (in addition to possibly breaking
current patches and such ;)

if we didn't want the root to be the default we could use something like
dtml-trans [path]:[path] with something like _root or __root being set
aside as a special name for starting at the root (otherwise it would start
in the current directory)...?



This patch changes lib/python/DocumentTemplate/DT_HTML.py so that you
can use paths for traversal in DTML entity syntax. The delimiter is ':',
as it is valid as part of an XML entity, but not valid as part of a Zope
object id.

You can use dtml-:foo:bar; to ensure that traversal occurs from the
root object.

This patch is against Zope 2.2.1b1. It relies on the
restrictedTraverse() api.

A 2.1.x version would be possible, but would be rather messy.

 Say I have a fully functional (and more importantly, working) Product
 will call A.

 I want to extend this Product's capabilities so I wish to derive another
 class from it, call it B.

 No problem,

 class B(A):
 .


 The question is, (I think the answer is no) is there a way to inherit
 (i.e. reuse common code and extend it) the manage_Add function and the
 dtml files from A???


Well by inheritance B has all the methods, properties etc you have in A. So
the answer is yes, if A has the foobar method then B will have a foobar
method.


Or do I misunderstand your question?

Not exactly. I want my individual pages to be accessible via URL (i.e.

And I want previous and next links even if someone finds the page
via its full URL - without going through any table of contents.

Or I miss something.

BTW: I use dtml-in to imlement table of contents.

[Zope] dtml-with object calls first?

2000-08-18 Thread Chris Withers

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

Re: [Zope] [Ann] Another Zope Book

2000-08-18 Thread Max Møller Rasmussen

Fra: Kapil Thangavelu [mailto:[EMAIL PROTECTED]]

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?

2 right you are. We need more info about Zope from a Python programmers POW.
Setting pages up in dtml is not that interresting from my point of view.

We need more detailed documentation on all the seperate modules, and far
more/better on making products.

dtml is not for programming and business logic, only for presentation.

Ok... this is the last time.

You can put a line:

del replacements

just after the for loop, and save a tiny amount of memory.
This might be a useful optimisation if you're dealing with a very large
list of words to replace.

[Zope] sending mail slow?

2000-08-18 Thread Chris Withers

Hi,

I've noticed that sending mail from within Zope the sendmail tab or
mailhost.send() is very slow (like it adds a few seconds to the time it
takes to get a page back from a post).

Why is that? how can I make it faster?

I'd thought about having the actual mail sending done in a different
thread/process but I don't know how I'd do that or whether it'd be worth
doing. I wonder where the slowness is coming from :S

cheers,

Chris

Thats good.

then ran
both the init.py and NTUserFolder.py files after entering my Domain and PDC

I ran them both to get the respective .pyc files.

Running a .py file doesn't create any .pc files. Those were
created when you next started Zope and the files were *imported*. You
didn't need to run them, but it has done no harm.

. my question is...

What now? What do I need to do next to actually get this stuff working as
opposed to taking up disk space, because nothing yet has actually happened
and, even if It has, I have no idea how to find out.

You need to create an NTUserFolder object in your Zope database, using
the /manage interface. You may have to delete any existing acl_users
object first.

[Zope] The date in Dutch - really last time!

2000-08-18 Thread Steve Alexander

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',

'May':'Mai',
'June':'Juni',
'July':'Juli',
'August':'Augustus',
'September':'September',
'October':'Oktober',
'November':'November',
'December':'Dezember'
}

for e,d in replacements.items():
replace_fns.append(
eval("lambda x: replace(x, '%s', '%s')" % (e, d)))

[Zope] dtml-else and 'unexpected end tag'

2000-08-18 Thread Chris Withers

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 ;-)

[Zope] DCOracle help required

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

I'm making an intranet for 100-200 people, with

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?

[Zope] cutting and pasting large folders

2000-08-18 Thread Jean Jordaan

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.

Very possibly.  Manually add some entries to the HOSTS file and see if

[Zope] Workaround and a tree and dtml-in problem

2000-08-18 Thread Chris Withers

Phil Harris wrote:
 Why isn't _ available in the tree tag?
 

The workaround is to wrap it in a

But now I'm confused.

Surely

  dtml-in postingValues
dtml-let posting="_.getitem('sequence-item',0)"
dtml-tree posting branches="postingValues"   
  dtml-var idBR
/dtml-tree   
/dtml-let
  /dtml-in

should produce the same results as:

dtml-tree branches="postingValues"
  dtml-var idBR
/dtml-tree

It doesn't :(

Why am I doing this you may ask? Well, I want to do batching at the top
level and, AFAIK, dtml-in doesn't support this :(

any ideas?

Okay, firstly, I notice dtml-tree doesn't support the standard

dtml-TAG "x" - dtml-TAG expr="x"

As the following:

dtml-tree "_.getitem('sequence-item',0)" branches="postingValues"

gives me:

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:

This is all in 2.1.6...

RE: [Zope] [Ann] Another Zope Book

Much of the aim of the "Product Developer's Guide" (see

 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?

[Zope] Product question, third posting

2000-08-18 Thread Daniel Rusch

I've created a folderish product. When I select that product from the
available objects list, thus creating an instance of that product, I can
create objects like dtml document and dtml method in the new folderish
object (very similar to what happens when you instantiate a folder
object, you can have a dtml method created in the new folder).

The question is why can't I create objects from the Products directory,
such as Local File System?


The code below works great, I get a dtml document, two folders each with
a dtml method in them
HOW CAN I CREATE A LOCAL FILE SYSTEM OR ANY OTHER OBJECT FROM THE
PRODUCTS DIRECTORY IN THIS MANAGE_ADD FUNCTION???


def manage_addSimpleSite(self, id, title='',
 createNewFolder=0,
 createEditFolder=0,
 REQUEST=None):
"""Add a new SimpleSite object with id *id*.

If the 'createNewFolder' and 'createEditFolder' parameters are set
to any true
value, an 'New sub Folder' and an 'edit sub Folder' objects are
created respectively
in the new SimpleSite.
"""
ob=SimpleSite()
ob.id=id
ob.title=title
self._setObject(id, ob)
try: user=REQUEST['AUTHENTICATED_USER']
except: user=None
ob.manage_addDTMLDocument(id='index_html', title='')
if createNewFolder:
if (user is not None) and not (
user.has_permission('Add User SimpleSites', self)):
raise 'Unauthorized', (
  'You are not authorized to add User SimpleSites.'
  )
ob.manage_addFolder(id='New'+id, title='', createPublic=1)
if createEditFolder:
if (user is not None) and not (
user.has_permission('Add Documents, Images, and Files',
self)):
raise 'Unauthorized', (
  'You are not authorized to add DTML Documents.'
  )
ob.manage_addFolder(id='Edit'+id, title='', createPublic=1)
if REQUEST is not None:
return self.manage_main(self, REQUEST, update_menu=1)


Thanks,

[Zope] ANNOUNCE: updated Hotfix release for recent mutable object issue

2000-08-18 Thread Brian Lloyd

Hi all -

We recently made a Hotfix release to address an issue 
dealing with Zope APIs returning mutable objects that 
could be changed inappropriately from DTML 
(Hotfix_08_09_2000). After further investigation, there 
was another aspect to the problem that was not addressed 
in the recent hotfix.

I've uploaded a new hotfix release (Hotfix_2000-08-17) 
that supercedes the one from the 9th and includes the 
extra fix required.

http://www.zope.org/Products/Zope/Hotfix_2000-08-17/

If you run a Zope site and allow untrusted users to edit 
DTML on your site, you should install this updated hotfix. 
There is no need to uninstall the prior hotfix release.
These fixes will also be in the 2.2.1 release, expected 
next week.

[Zope] Can't change title of a common instance property sheet

2000-08-18 Thread Jeff Sasmor

I suppose this is some sort of lack in the Zope management UI, but
maybe someone else knows how to do this:

If you create a ZClass property sheet you can pick an ID and a title.

But you don't seem to be able to EDIT the title of the property
sheet ever again.

Is there some magic property sheet property name or
is there just no way to edit the title from the management 
interface?

The other bizzare thing is that you can export a property sheet,
but there seems no obvious way to import one anywhere.
Anyone have a clue on this?  What's it there for?

TIA

[Zope] Re: Xron test

2000-08-18 Thread Loren Stafford

Nick,

Two other Zopistas reported similar problems. Both succeeded eventually in
getting Xron started, but we didn't succeed in diagnosing the problem, nor
in determining precisely how to work around it. I myself haven't been able
to reproduce the problem.

The problem seems to occur only on Linux, but it does not always occur. Some
users have successfully started Xron on Linux with no problem. The problem
seems to have to do with contention for a lock on ZODB. Did you see any log
or console message that would confirm this?

One user went to the console and killed all the Zope processes that were
running at the time, then restarted Zope from the command line. The second
time, Zope started up correctly with Xron.

Another user thought that he had mistakenly tried to start Zope while logged
in as root. When he restarted as a different user, Zope started up with Xron
correctly. I suspect that the user was not relevant to the Xron problem (it
is normal in some installations to start as root), but that the restarting
was the key.

One user thought that the monitor process contributed to the lock
contention. I don't know, but it might be worthwhile to try to restart Zope
without the monitor (changing the start-up options to disable the monitor).

The problem seems to relate to Xron's creating the Schedule catalog the
first time the Xron product is loaded during Zope start-up. If you succeed
in creating the Schedule one time, the problem will not recurr, as Xron will
just use the existing Schedule.

I hope that helps you get started. Let me know how it goes. I'll copy this
email to the zope list in hopes that someone else can shed some light on the
problem.

 Hi Loren,

 I have a problem with installing Xron 0.9 onto my machine. Currently,
 I'm running SuSE Linux 6.4 on a 600MHz/128Mb/20Gb PC. I have followed
 the release note and set the STUPID_LOG_FILE environment variable to
 point the log file, and Xron itself is, of course, resides in the
 /Products directory. When I start Zope, the console looks okay. However,
 the browser keeps on loading and loading and could not show the Zope

The problem is: I have a Zope 2.1.6 with SiteAccess and Apache 1.3.12 with
the mod_proxy and mod_expire set up to that all request get at por 80 by
Apache are proxed back to port 8080 of Zope. SiteAccess garantees that this
cycle works all the time and port 8080 is never accessed directly.

This works fine. The problem is that the Apache proxy is not caching the
pages as it should, so that requests made to Zope once are not made again
until expired from the cache. This results that every single request made to
Apache goes directly to Zope and than the lack of robustness of ZServer
makes it very slow and unstable (as expected).

The strange thing is that the directory used for the cache is been filled up
with files but it looks like Apache is ignoring them and going directly to
Zope. When I shut down Zope, it never goes to the cached files and when I
make requests to Apache the Zope´s log grows up all the time for the same
bunch of pages.

Here´s the configuration in my httpd.conf

 CacheRoot "D:/Program Files/Apache Group/Apache/proxy"
 CacheSize 5
 CacheGcInterval 1
 CacheMaxExpire 24
 CacheLastModifiedFactor 0.1
 CacheDefaultExpire 1
 CacheForceCompletion 90

 ProxyPass /zope/ http://10.10.10.176:8080/
 ProxyPassReverse /zope/ http://10.10.10.176:8080/

ExpiresActive On
ExpiresDefault A86400
ExpiresByType image/gif A604800
ExpiresByType image/jpg A604800
ExpiresByType text/html M43200


Anyone knows why this happens? What´s the workaround? I searched through all
the web and find nothing about the mod_proxy configuration so it´s turning
to be extremelly difficult to maintain the Zope site, even with the robust
Apache as the front-end.

Thanks

Re: [Zope] sending mail slow?

2000-08-18 Thread Loren Stafford

From: "Chris Withers" [EMAIL PROTECTED]

 I've noticed that sending mail from within Zope the sendmail tab or
 mailhost.send() is very slow (like it adds a few seconds to the time it
 takes to get a page back from a post).

 Why is that? how can I make it faster?

 I'd thought about having the actual mail sending done in a different
 thread/process but I don't know how I'd do that or whether it'd be worth
 doing.

You could use Xron to schedule sending the email. You could schedule it for
later or for "now". Either way the email would be sent asyncronously from
the original request. (But check out another email dated today titled "Xron
test").

Re: [Zope] [Ann] Another Zope Book

2000-08-18 Thread Andy McKay

There is room for both books. Zope is a powerful and very deep products. The
majority of users are unlikely to go into a great deal of python, most are
going to use the dtml and other basic functionality. If Zope is going to
increase its market then this sort of book is essential to make Zope
accessible. Can I help at all?

But a book covering the internals will be useful. One of my gripes about the
documentation is how spread out and hard to find it is there's Wiki's here,
presentations there... I've often searched zope.org and come up blank, when
people on the mailing list can point it to me in 2 mins. But searching
zope.org is another matter entirely :)

my 2 cents.

 I think most developers are forced to learn

 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?

 2 right you are. We need more info about Zope from a Python programmers
POW.
 Setting pages up in dtml is not that interresting from my point of view.

 We need more detailed documentation on all the seperate modules, and far
 more/better on making products.

 dtml is not for programming and business logic, only for presentation.

 What went wrong here and how i fix this problem?

Aha, it worked in 2.1.6 eh? That's the tip off. A *major* change between
2.1.x and 2.2.x is in the security dept. 2.2.x runs all methods using the
security level of the _owner_ of the method, regardless of whether this is a
lower or higher level than the currently authenticated user. My guess is
that your method has no owner (which is what pre-2.2.x objects default to
when run under 2.2.x). This means it is running as anonymous which does not
have rights to do what you want. Specify an owner for the method that has
sufficient rights to do what you want and try it again.

Good luck,

[Zope] Installing Zope

Zope will install easily, if I put everything into my commercial host's cgi-bin.  Is 
this asking for trouble?

Yes, I have read gldnspud's "Third-Party Web Host" notes.  But things are different 
enough on my host to cause problems.

In all the computer languages I know there's already a convention for

dtml-foo.bar\.dot.y

But I prefer path-style identifiers:

dtml-/foo/bar\.dot/y

Then the correspondence to the site's folder structure is evident. 
Plus you can support both relative and absolute paths without 
confusing anybody:

dtml-foo/bar\.dot/y

Or, if y is a *property* of bar.dot,

dtml-foo/bar\.dot.y




Dont put . in id's... I try not to anyway. Could we say . or if your id has

somewhere on one of you pages you have a link something like

that's a relative link and thanks to the magic of the Zope automatically

  If you do dtml-with object where object is something callable, it

  That's a bit unpleasant for things like Squishdot Sites which do

  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.

I, definitely, prefer the current implementation to making
"with" the (only) exception: currently, whenever you
use the name parameter of a tag, the object is called
when it is callable.

If this would be changed, I am almost sure, Chris Withers would later
complain about the inconsistency :-)

[Zope] Probable Bug in OFS.Image.index_html

2000-08-18 Thread Dieter Maurer

Today, I met again a strange problem:

  I wanted to implement an image relay for an international project:
  something like: if an image in the target language is available,
  take it, otherwise, the english image.

  My DTML looked like:

dtml-let src="have_image(name,language) and _.getitem(language) or EN"
  image="_.getattr(src,name)"
dtml-var "image.index_html(REQUEST,RESPONSE)"

  The result was very strange:

When I forced Netscape to reload the image (SHIFT + reload),
everything worked fine. 
However, when I did a simple reload, it sometimes worked
and sometimes did not (showed a broken image).

When I loaded the image with Pythons httplib, everything
worked fine.

  I tracked this down to line 219 of "OFS/Image.py":
Zope arrives their, when it receives an
"IF-MODIFIED-SINCE" header and determines that
the browser has an up to date image in its cache.
Zope correctly set status 304 and then
returns "RESPONSE".

It seems that this is not a problem, when "index_html"
is directly called from ZPublisher.
However, in the context of the above "dtml-var",
it confused Netscape completely (I can understand that!).

  I changed the "return RESPONSE" into "return ''"
  and everything works fine again.


I will put this into the collector.

Aha! Found it I think.

The list of roles you see are possible selections. It's a

need to select the roles you want your user to have, they'll
be
highlighted.

The fact that they are listed doesn't mean they are selected

[Zope] Odd problems with SiteAccess?

2000-08-18 Thread Christopher Heschong

I have a directory with a SiteAccess rule in it.  Under that directory,
versions and Zcatalogs no longer seem to work.

This is with  (SiteAccess-2-0-0b3)) and Zope 2.2.0 and 2.2.1b1

When I add a version, I can't start working in it.  Clicking on the button
doesn't seem to do anything.

When I add a Zcatalog and try to find items to it, I get the following
error:

Zope has encountered an error while publishing this resource.

Error Type: IndexError
Error Value: list index out of range


Traceback (innermost last):

Can anyone help or suggest a way around this?  I'm assuming it's a problem
with SiteAccess and interaction with Zope 2.2x?

 I think Andrew completed the extraction of the ZODB.
 This means, Zope applications can use it for persistency.

AFAIK you can't store objects in property sheets. you can store them as

Re: [Zope] Fourth Posting, is this really that difficult or have I been blackballed :)balled :)

2000-08-18 Thread Kapil Thangavelu

btw daniel,

i've looked at some your postings for the day and i thought i should
tell you that most of your problems would go away if you did subobject
adding in your __init__ method within your class or in the hook method
manage_afterAdd within your class. for future reference. You'd get all
the benefits of inheritance. Let manage_add to do just that, instantiate
and set a instance of your class.

[Zope] What's the best way to go from Zope to Oracle time and back..

2000-08-18 Thread Chris Beaumont

Total newbie question here..

The subject line says it all..

What's the best way to go from Zope to Oracle time and back?

I would like to store the "beef" of my data in Oracle tables, and 
"instantiate" Zope objects from those tables..  Obviously this will 
require going back and forth between Zope and Oracle datetimes.. 
What's the best way to do this?

I thought I had seen something like this in a HowTo, but I cant seem 
to find it..

Thank you.

SQL defines a new document type 'sql template' and defines the tag within

It doesn't look currently possible do define a general use tag that works
the way I want (yet). I'll keep looking at it. I might be able to define

[Zope] Dots versus underscore in DTML

2000-08-18 Thread George Osvald

I know dots  in file names are important when submitting the pages to the
search engines. When I use them however, I'll loose the view tab(folder)
when trying to view say index.html and I have to click on the file and then
view it. If the file was named index_html I could just click on the view tab
in the folder to view it. Is it possible to have dots in my methods and
still have the view tabs on my folders?

Anyone?
