Re: [Zope-dev] Common Icons or Free Icon collection

2000-06-26 Thread Holger Lehmann

Linux distributions come bundled with a bunch of "free" icons. And I beleive
there are some ...tar.gz archives on metalab.unc.edu (former sunsite.unc.edu).

 Hi,
 
 I need some icons/pics for my Zope project. Are there any common icons for
 Zope I could use, and if not, shouldn`t there be such a thing? Does anybody
 know of any other collection of free icon-collections available ?

Almost surely, it will work.

But it probably will not use the Unicode support automatically.

That much I do know. I'm migrating to 1.6 so I can add this support to

The intended behavior (at least in zpatterns-0.3) was to get an item
from one of the racks. This is why I think this is a bug. It changes the
behavior of zpatterns-0.3 because it returns the value from the first
rack, and ignore the others. I wonder then of what use is the other
racks... (or is this intended? I don't think so)
If a rack returns None, then we assume the rack is not responsible for
storage of that element, and go on with the next rack in the list

I believe RackMountable/Racks/Specialist are not the same as

RE: [Zope-dev] Re: [Zope] Please test this Zope 2.2 beta 1 ZSQLMethods fix...

2000-06-26 Thread Brian Lloyd

 TJM That did it!  But...  :) I ended up having to re-create all
 TJM my ZSQL methods, which was funny because they all worked in
 TJM the beta 1 but not in beta 2.  I kept getting len() of
 TJM unsized object errors.  Anyway, re-creating them all from
 TJM scratch (ugh..)  solved that problem.
 
 So - any news on the re-creating all the sql methods bit?  I am about
 to start doing the same thing.  Any way to work around this?

You certainly shouldn't have to do that - AFAIK, TJ's was the 
only report of that behavior. There ARE other people reporting 
something about "len of unsized object" errors with their SQL 
methods after upgrading that I'm trying to get to the bottom of. 

Unfortunately, I haven't been able to reproduce that locally. I 
would really appreciate if some folks would:

  o !!backup your original Data.fs!! before trying out 2.2 beta 2

  o If you have any problems with the SQLMethods, if you can send 
me your zipped object db (and info on what products need to 
be installed to reproduce your environment) that would help a 
lot. (send a copy of the back up Data.fs)

It would be great if someone can send me one where the SQL stuff 
is based on Gadfly or MySQL connections if possible...

[Zope-dev] 2.2 permission problem with adding ZClass Instance as user in DTML

2000-06-26 Thread Bill Anderson

OK, I have aproblem that is largely baffling me.

I have Meerting Management installed and working properly ... for the
most part.

If I use the following code to add a Managed Meeting, it works fine:

a
href="/LAN/manage_addProduct/MeetingManagement/ManagedMeeting_factory"Add
LAN Party/a

I get the form, and it adds as user just fine. Anonymous wokrs fine too.

However, this is not only ugly, it wreaks havoc with my navtrail. So I
copied my code from KnowledgeKit, and changed to suit the product:

Form calls as action the method CreateEvent:
dtml-with "manage_addProduct['MeetingManagement']"
dtml-call "ManagedMeeting_Add(_.None, _)"
/dtml-with

And it barfs on permissions, requesting a username/pass combo through
Basic HTTP Auth, as opposed to the cookie login I am using (Membership
0.6.0). The traceback is less than helpful, but if anyone wants it, I'll
post it.

Any help much appreciated, since I'll be able to return to working on
some cool stuff once this is resolved.

 Zope 2.2.0b2, clean install.  Works fine.  Add EMarket.  Now the
 management is broken.  Accessing the base URL of the site with
 /manage_main appended gives you the file list view of the root
 folder, with no prompt for authentication.  Accessing /manage
 prompts for a login, but the right panel view is the import/export
 screen and not the folder list.  There's other weird stuff, like
 a key error on "a_", which appears to be temporary variable used
 in one of the DTML management pages.
 
 I've read Brian's 2.2 product security update, and it looks to me like
 EMarket is Doing the Right Thing (though I haven't checked completely for
 unprotected methods yet), which makes sense since it was a working
 product grin.
 
 I have a private report that eTailor also has this problem, but haven't
 tested it myself.

If I am not the source of that report, chalk up another one for the
tally.

I have shown that a zero length __init__.py file in the EMarket

Re: [Zope-dev] calling external method from external method

2000-06-26 Thread Dieter Maurer

Robert Roberts writes:
  How do I call one external method from another external method?
You simply call it.

  Here is what I mean:
  
  The user has entered the id of valid external method in a form field.
  (This is during setup of a Product and is not accessible anonymously)
  
  At a later point, an external method is running (part of the product)
  that gets the id that was entered above.
  
  I would then like to execute the method belonging to that id from
  within the python method that is running.
Your main problem: resolve the "id" into an object.
For this, you should either pass a namespace or an object
as parameter to the first method.
If you use a namespace "ns", you access "id" by "ns[id]",
for an object "o", you would use "getattr(o,id)".

Once you have the method corresponding to "id", you simply
call it.

[Zope-dev] 2.2.0b3 - try/except changed?

2000-06-26 Thread Dr. Ross Lazarus

This new beta has fixed some problems for me and the documentation on
the new security model for products has really helped...

However, I seem to be getting errors in previously (2.1.6) dtml
try/except structures.
1. dtml-except now seems to die unless there's an error_type parameter
(I usually don't need them...) - presumably a new buglet?

2. dtml-trydtml-var "fooZSQL"/dtml-try doesn't catch exceptions in
SybaseDA connected ZSQL method fooZSQL anymore?? I'm pretty sure this is
a change from 2.1.6 behaviour - and a change for the worse IMHO - it's
very useful to be able to expect a try/except structure to trap ALL
errorsgracefully

Could some kind soul confirm that it's not just me so I can pop this
into the collector please?

 Check fo rthe permission "Manage Properties". This one threw me for a

 in the archives.
 This works wehn I call the addForm directly, yet when I use a 
 form local

 use in KnowledgeKit), it doesn't seem happy, requesting authentication
 through Basic Auth, as opposed to the Cookie Login form I use 
 currently
 (Membership 0.6.0).
 
 I am working on this, and will pst a fix as soon as I have one.

I solved this by giving the piece of code that changes the properties the
Proxy Manager role.

[Zope] Problem with the datatype lines

2000-06-26 Thread Anders Holmbech Nielsen

Hi Zopers,

I have found out that when using the datatype "lines" in my own 
ZClass it won't obey to the locale settings. That means that the 
words coming from "lines" look like: t/370nk. And therefore they 
don't get correctly indexed in the database.
I'm running Zope 2.1.6 (on both linux and winnt 4.0).

Is there an update to this problem or a workaround ?


Thanks in advance

[Zope] Unique Identifiers for Zope Objects

2000-06-26 Thread Michael Abbott

I'm looking for an internal globally unique identifier for objects in my
Zope store.

I know that I can use id=object.absolute_url() to create an identifier and
then something.resolve_url(id) to recover the object from the identifier
-- but I have two problems with this API:

1. The URL is not really a global identifier, as resolving it seems to
depend on the something from which I call resolve_url().  In particular,
if the id is created when Zope is running normally (as a service), and
resolved when running Zope from the command line debugger, the resolve
fails.  This is not good.

2. The need to locate an object something carrying the resolve_url()
function is a problem; in particular, I would find it helpful if I could
resolve my global identifier from within a __setstate__() method (where I
have no access to local Zope variables), so I really want a genuinely global
function for resolving my id.

Any suggestions, or do I have to dig into the (disagreeable and uncommented)
bowels of Zope and write my own?

(If this is on the wrong list, please point me to the right one.  Thanks.)

 yes but the repitition of "link text" could be a real pain if "link_text" is
 big. Repitition is always a maintance nightmare.


If it is, make it a method or attribute.

dtml-if X
   a href="a_url" dtml-var linktext/a
dtml-else
   dtml-var linkText (No Link Available)
/dtml-if X

You could make the links objects, such that:
dtml-in "objectValues('Link Object')"
  br a href="dtml-var linkURL" dtml-var linkText /a
dtml-else
  p Sorry, no links available at this time.
/dtml-if Link Objects

The real question is why have link text that doesn't link... ;)

Re: [Zope] MySQLDA Problems with simple constant/function queries

2000-06-26 Thread Monty Taylor

This is actually fixed in both 1.1.4 and in 1.2.0. The problem has to do
with type conversions from a dictionary in the adapter. Any type of
non-row function or aggregate returns a type of 'unhandled' which was
not mapped in the conversion dictionary. This is fairly much the bug
that called for 1.1.4 to be released. You're right, though, very easy to
fix.

1.2.0 deals with the problem by taking a different approach to
type-mapping.

 Of course "select * from table" works.
 
 When I look into db.py, the error doesn't look very hard to fix, I think
 I'll give tomorrow. Is there some API documentation of what a DA is
 supposed to do?
 
 Since the 1.1.4 query() code is identical, I think the problem appears
 there as well.

[Zope] Translator package/project died or what ?

2000-06-26 Thread Holger Lehmann

Hi everyone, especially J. David Ibáñez and Federico Di Gregorio :-)

Since Federico did not reply to my mail I am posting this on the list to gain
responses.

We **need** a translator package for Zope. We will be hosting a site that will
have the feature to "speak" different languages.

So I got Translator-0.5.tar.gz from somewhere (do not ask me where, I forgot).
Unpacked it and restarted Zope. The product is broken since it tries to import:
from Shared.xmlio import XMLio
But this is obviously not available (I tried finding it on zope.org  and
with google/altavista). The only available xml package is in DC.xml and is
based on xmllib.

Now here is the question: Does anyone have the XMLio stuff ? If so can this
someone be so nice and either post the URL here or make it available and post
the URL here ?
If all this is in vain and that package will not be developed any further, can
someone tell me if there is another solution out there ?

- TIA Holger

[Zope] Zope 2.1.6 Bug?

2000-06-26 Thread James W. Howe

I'm running Zope 2.1.6 under Windows 2000.  I've encountered a situation 
where I can cause Zope to completely hang.  For example, if I create a 
DTMLMethod called test in the root folder and give it this 
contents  (leading spaces on the table tag are important):

 table width="100%" border="0" cellspacing="0" cellpadding="0"
   tr
 tdHello/td
   /tr
 /table

and click the View tab, the page displays as expected.  However, if I edit 
this to look like this:

 table width="100%" border="0" cellspacing="0" cellpadding="0"
   tr
 tdHello/td
   /tr
   tr
  tdGoodbye/td
   /tr
 /table

and click View, Zope goes off and never returns.  The Python.exe file 
continues to consume CPU but doesn't display anything.

However, if I remove the leading spaces before the table tags, save my 
changes and then click View, the contents are displayed immediately.  I 
then experimented with adding one space before the tag.  The contents 
displayed, but after a pause.  Two spaces paused longer.

Can anyone else verify this behavior?

Thanks.

Re: [Zope] Internationalization

2000-06-26 Thread Rob W. W. Hooft

I only have a few internationalized pages, but I'm more than half-way
happy with a very simple approach:

1) an External Method "preferred_lang", which takes a list of possible
   languages as argument, and returns the language from that list that
   has the highest ranking in HTTP_ACCEPT_LANGUAGE. If there is no
   hit, it returns the first language in the list.
   
   import string

   def preferred_lang(self,langs):
  for lang in map(string.strip,string.split(self.HTTP_ACCEPT_LANGUAGE,',')):
if lang in langs:
  return lang
  return langs[0]
   -
   This External Method is available as "PreferredLanguage" on the
   root folder.

2) In each internationalized page, I call the External Method with a
   list of the available languages (it is not the same for all
   pages), and then select the contents based on the result.
   
   dtml-var standard_html_header
   dtml-call "REQUEST.set('lang',PreferredLanguage(REQUEST,['en','nl']))"

   dtml-if "lang=='nl'"
   H2De Hooft Familie Webdienst/H2
   dtml-else
   H2The Hooft Family Web/H2
   /dtml-if
   etc
   -

One advantage of this approach is that it keeps the different versions
together (making updates to the information easy to keep consistent).
One disadvantage of this approach is that it keeps the different
versions together (making it difficult to appoint different people to
maintaining the different languages), and another disadvantage is that
it clutters up the dtml source.

Suggestions for improvements always welcome.

Rob Hooft

Re: [Zope] ZODB performance: reads to writes

2000-06-26 Thread Evan Simpson

- Original Message - 
From: Jimmie Houchin [EMAIL PROTECTED]

 This is what I understand based on your reply and from the paper by Jim.
 
 1. That there are solutions currently being worked on by DC (implied).
Yes, worked on does not mean 'Coming Soon to a Zope near You!' :)
 
 2. That if an app, either by it's nature or thru it's developers design,
 eliminates or handles conflicts before commits are made to the ZODB,
 that high write situations are not a problem.

AFAIK, these are both correct.

 Is number 1. below something that would take place with BTree Folders?

Yes.

content, all content is generated dynamically.

See http://www.codecatalog.com for an example of a site which does a lot

I don't know if this is what you mean, but you can use webalizer or
another statistics package on the log file created by zope. If you run

I don't know if it help, but
My problem was to serve any request to Apache to the ZServer, and to change
the URL like that:
http://path/file.html(Apache server)
to
http://path:8080/?file.html (ZServer, with the file as a query_string)

and I wanted it to be transparent . So, I matched all the URLs with htm and
html extension to modify them.
The first thing u have to do is defining the regular expression which will
match the URL you want to serve as a proxy
then u can insert, and modify your URL (which will be served transparently
with the [P] flag.

the big problem is to find a way to match what u want, the syntax is horrible
(I passed a whole day on these three lines).

RE: [Zope] Unique Identifiers for Zope Objects

2000-06-26 Thread Chris McDonough

 I'm looking for an internal globally unique identifier for 
 objects in my
 Zope store.

The object path would be that.

 I know that I can use id=object.absolute_url() to create an 
 identifier and
 then something.resolve_url(id) to recover the object from 
 the identifier
 -- but I have two problems with this API:
 
 1. The URL is not really a global identifier, as resolving it seems to
 depend on the something from which I call resolve_url().  
 In particular,
 if the id is created when Zope is running normally (as a service), and
 resolved when running Zope from the command line debugger, the resolve
 fails.  This is not good.

Yes, the REQUEST object is not available during a command line session.
This can be a real pain.

What you can do is (in Zope 2.2) use 'unrestrictedTraverse()' and
'restrictedTraverse()' in combination with the string.split() of the
relative URL as obtained via ob.absolute_url(relative=1), e.g.

ob = self.myob
oburl = ob.absolute_url(1)
obpath = string.split(oburl, '/')
obpath.insert(0, '')  # a null string as the first item in the
[un]restrictedTraverse list means relative to root
sameob = self.unrestrictedTraverse(obpath)

(this is untested, I think it's right...)

 2. The need to locate an object something carrying the resolve_url()
 function is a problem; in particular, I would find it helpful 
 if I could
 resolve my global identifier from within a __setstate__() 
 method (where I
 have no access to local Zope variables), so I really want a 
 genuinely global
 function for resolving my id.
 
 Any suggestions, or do I have to dig into the (disagreeable 
 and uncommented)
 bowels of Zope and write my own?

Well... if you don't plan on using mountable database features within
Zope, each Zope object will have an attribute "_p_oid", which is the
64-bit object id (stored as a string) that is used by the storage to
keep current and historical revisions to the object.  It's not
recommended that you base an extensible system on this attribute,
however, because using multiple storages within a single Zope instance
(such as when you use mountable databases) almost guarantees that this
identifier will not be unique.  I believe that mountable databases in
Zope will quickly become a common implementation practice.

I wouldn't suggest writing your own GUID generator for general-purpose
Zope objects.  I would promote the use of [un]restrictedTraverse and use
the object path as a unique ID.

[Zope] HTML Editors that recognize DTML (was bastardized form ofXML)

2000-06-26 Thread Jeff Peterson

As promised I did some checking over the weekend.

As for Windows editors, Homesite WILL let you create tags,
it works quite well actually.  One draw back (or a blessing, 
depending on your view) would be that it would force you to 
do dtml attributes long form, for example:

dtml-var name="foo" rather than dtml-var foo

the nice thing is that you would have a nice drop down menu 
of choices.  It supports syntax highlighting and has a ton of
helpful features.  In addition, if you gather enough Homesite 
"clue" you could also create your own wizards to accomplish 
certain tasks. 

Also for Windows there is Multi-Edit.  Not as powerful as Homesite
as an HTML, CFML, ad infinitum editor(well, maybe as powerful but 
it has all sorts of toolbars and buttons to push...annoying), but 
it has support for a tremendous number of legitimate programming 
languages built in including PERL, Python, JavaScript, C/C++, Delphi, 
ad nauseam.  While you can edit all this in Homesite, Multi-Edit 
provides support for compilers, error messages, and templates for 
almost any programming language you can think of (ad nauseam, remember?).
This doesn't necessarily help with DTML but maybe it's not all you do.

Both of these are priced nicely, Homesite goes for about $100 and 
can be checked out at www.allaire.com, while Multi-Edit prices at 
around $130(online) and can be found at www.amcyber.com. 

For Linux there is a nice little editor called NEdit.  NEdit 
includes customizable syntax highlighting, spell checker, etc.  
Unfortunately I know not of whether you can create customized tags
but, I doubt it very much.  Not as nice as the Windows stuff and 
there may be better editors made for Linux but this one does 
nicely in a pinch and beats the snot out of vi.  RPM's, and source
are both available, for free of course. 

That's my $.02,

RE: [Zope] Moving Z Classes around

2000-06-26 Thread Brian Lloyd

 Having discovered that [my] Z Class is in the wrong product, 
 I'd like to
 move it elsewhere.  The obvious thing to do is to use Cut + Paste;
 unfortunately, I get:
 
   The item my-item does not support this operation.
 
 (The function manage_copyObjects is not happy!)
 
 I can't think of another way to move my classes without 
 rebuilding them --
 any advice?

Michael,

I agree that this is a pain, but it is a fact of life for now 
in ZClass development. ZClasses have a different relationship 
with other Zope objects than normal, in that other instances 
in the object space refer to them as their class. That makes 
picking them up and moving them something not to be done 
lightly. In the Python world, this would be equivalent to 
pickling a bunch of objects and then moving the class for 
those objects to a different package. Without some explicit 
action, all of the pickled objects would break because they 
would be referencing a class that is no longer there. 

It's the same deal with ZClasses. It may be possible in the 
future to move ZClasses around, but something will still need 
to be done about existing instances created from a class that 
moves. So far we have avoided the hard thinking required to 
solve that :^) This would be a good candidate for a proposal 
in the forthcoming ZopeDev area on Zope.org. More on that 
later...

RE: [Zope] Zope 2.2.0b2 - PythonMethods

2000-06-26 Thread Brian Lloyd

I remember DC submitted PythonMethods into CVS, but I cannot find

 be separated Product forever?
 
I have downloaded latest PythonMethods and successfully

 something?

Oleg, 

There is still some work that we want to do on PythonMethods 
to get them where we want them for inclusion in Zope -- we 
need to get them well integrated with the Zope security 
policies and roll in some other work that will make all 
method-like objects behave in more consistent manner. I'm 
hoping that this will happen relatively soon (though I can't 
give you a date).

Until then, there's no problem using the latest distribution.

Re: [Zope] Generating products that perform a smart clone of a mastersite?

 What I think I need to do is to develop a facility that makes a 
 tutor's site into a product. Instantiating such a generated product 
 should make a smart clone of the master site, smart in the sense that 
 only active objects are actually cloned, but static files are shared 
 among all instances of the site. I suspect that ZClasses might be 
 involved to achieve this, but are there any issues with the fact that 
 a master site could contain folders? Furthermore I'd like a tutor to 
 be able to visit their productised site to update it, without seeing 
 a lot of alien stuff; changes to the master site should be reflected 
 in all instances of the site.

You've got a couple of problems, given the way ZClasses and Python
products currently work.  Either on one of them would allow you
to set up the static pages in a shared, updateable way; the catch
comes in how the updates get done.  For changes to be reflected in
a python product, you'd have to give the faculty member the ability
to change files in the server filesystem hierarchy.  This is problematic.
With ZClasses you can use the Zope security support to control who
updates what.  However, currently ZClasses can only go in the
Control_Panel/Products folder.  This means that all tutors will see
the products/classes used by all other tutors, which you say you wish
to avoid.

I think the best solution to this would be if you could have ZClasses
stored in a mountable storage.  Then you could have one storage per
tutor.  I don't think that is currently supported, though.

Another approach would be to have a separate Zope instance per
tutor.  This has the disadvantage of making code shared between
tutors harder to maintain.  If *that* code is in a python
product, though, you could use the INSTANCE_HOME support to have
the python product code shared between all the instances.

In short, I do think you are on the right track, but you've got
some hurdles to get over to achieve exactly what you want.

 This is in Win95 Netscape. When I view the source I didn't anything

I have changed the portal name to zdpmembers, and now it works again.

  You also have to see that the topics in the ZDP-Portal
  are normally not related in a way like an article is,
  so I have not added a navigation, even though I had considered it.
 
 I don't think it is a problem for unrelated content or articles. It also
 doesn't necessarily have to be site wide thing. In this particular
 instance all three were related to each other and referenced each other
 via the pros and cons.

In this case I will have to make explicit links to the related content,
like you propose. It is worth the extra effort.
 
 If you think date is not a good indicator of currency, then howabout
 having Zope versions with which it is accurate for ?

The date will play a role when the changes history of documents
is implemented. 

 ie: Works with Zope
 2.x or Zope 2.2.x, etc. or even a range 2.0-2.1.x. This would allow for
 changes in Zope which break certain things. For example any information
 on the security model changes between 2.1.x and 2.2.x.
 Doing it this way makes it less date dependent. It also allows for
 people who are using older versions of Zope to understand if it is
 relevant for them.

In my opinion, things like that should be noted in the text, or in
the changes history (Something like "adopted to Zope 2.2 security model
on 22nd of July 2000). 
 
  I have noticed that product as well, but didn't find the
  time to check it out (There is no info on the product

[Zope] parsing strings in DTML

2000-06-26 Thread Timothy Wilson

Hi everyone,

I'm working on what should be a simple problem.

I pulling an address out of an ldap query and the data is in the form of a
$-separated string. Example:

101 Main St.$Anytown$MN$12345

Please correct me if I'm wrong, but I could probably do dtml-call
"REQUEST.set('parsed_address', _.string.join(old_address, '$')" except for
the fact that getting "old_address" (the $-separated one) would require its
own dtml-var old_address statement. I can't nest dtmls so how to I
combine these?

Second question... Once I've got my string parsed into a list called
"parsed_string", what's the syntax for accessing certain elements of the
list?

Thanks.

-Tim

P.S. Maybe I should do this in an external or python method, but I thought
it would be overkill for a single operation like this. Am I wrong?

[Zope] Cache X MySQL

2000-06-26 Thread Rogerio Atem de Carvalho

Dear coleagues,

I decided to use Zope as an Interface to maintain and 
search a touristic information database. All text is 
stored in MySQL tables and images will be stored 
outside the database, for cache reasons (I will keep 
only the path as TEXT columns in MySQL tables). My 
question is: for me to have an efficient cache system, 
Am I supposed to store the images as Zope Image Objects 
or can I store them outside Zope, in normal (Linux) 
folders? 
If I store them poutside Zope, is Zope able to cache 
them???

regrads,

Rogerio Atem

This is exactly correct.  Inside the quotes you are in python, and
so you can reference variables from the namespace by their unadorned name.

 Second question... Once I've got my string parsed into a list called
 "parsed_string", what's the syntax for accessing certain elements of the
 list?

parsed_string[0], parsed_string[1], ...  (inside an expr, of course).

I'm not sure I get you right.
try something like (untested):

dtml-call "REQUEST.set('parse_address', _string.split(old_address, '$')"

for parsing the string


Second question... Once I've got my string parsed into a list called
"parsed_string", what's the syntax for accessing certain elements of the
list?

By slicing:

dtml-call "parsed_string[0]"

gets you the first element parsed_string[1] the second etc

parsed_string[1:] is everything after the second ;-) element of the list

parsed_string[:5] is everything up to element 6

parsed_string[1:5]  is everything from element 2 to element 6

parsed_string[-1] is the last element of the list.

If you want to know more, you should probably look at the Python docs, as
this is Python stuff.


P.S. Maybe I should do this in an external or python method, but I thought

No, I think you're right, but others may disagree.

You're right, of course, about the "split." A slip of the typing fingers.

 this is Python stuff.

Doing this in Python is easy. That's not the problem. I've been struggling
with all of the RESPONSE.set, REQUEST.set, etc. stuff. I can't keep it all
straight. Adding the dtml layer to this really adds to the comlexity of it
all. I just need more Zen. :-)

Thanks for the help.

[Zope] CASE tools and Zope

2000-06-26 Thread Alexander Chelnokov

Hello All,
A newbie question. Is there any hints and tricks how to establish
connection between CASE like ERwin and Zope? We plan to develop a
a medical record system based on SQL database so data scheme is
essential. And all business rules will be held in Zope. SQL tables as
I realize should be mapped to ZClasses - if there is an entity
"Patient Personal Data" with columns Name, Gender, Date_of_birth,
Street_address and so on, then ZClasses with appropriate properties
are to be created. At the moment ER model can only be viewed and no
more while working in Zope. Is it the only use of data modelling tools
for Zope development? Or there is some other techniques of such
application development one should be aware of? THX in advance.

[Zope] Zope 2.2.0 beta 3 released...

2000-06-26 Thread Brian Lloyd

Hi all,

Zope 2.2.0 beta 3 has been released - you can download it from
Zope.org:

http://www.zope.org/Products/Zope/2.2.0b3/

This release resolves the "len of unsized object" error some 
folks were seeing with their SQL methods as well as an issue 
with broken installed products causing a recursion problem 
instead of appearing as normal "broken" objects. I'm hopeful 
that this will be the last 2.2 beta, assuming that no other 
real problems arise that need fixes tested before final.

For more information, see the CHANGES.txt file for the release:

http://www.zope.org/Products/Zope/2.2.0b3/CHANGES.txt

If you are still using a 2.1.x version of Zope, be sure to 
see the document upgrading to Zope 2.2:

http://www.zope.org/Products/Zope/2.2.0b3/upgrading_to_220

for information on the recent changes to the Zope security model 
and other upgrade information.

You should never "nest" DTML like you are suggesting. It won't work.

Variables set through REQUEST.set are immediately accessable in DTML
expressions after it, i.e.:

  dtml-call expr="REQUEST.set('i', 0)"
  dtml-var i
  dtml-call expr="REQUEST.set('i', i + 1)"
  dtml-var i

Notice all I did was "i + 1", not "dtml-var i + 1". You simply reference
it, as you would in python.

[Zope] ZOracleDA

2000-06-26 Thread Kiran Jonnalagadda

Hi,

I'm trying to install ZOracleDA. I've managed to get DCOracle to build,
but the test fails with this traceback:

-
[root@balrog src]# python DCOracle_test.py 
Traceback (innermost last):
  File "DCOracle_test.py", line 1, in ?
import Buffer, oci_, sys
ImportError: /u01/app/oracle/product/8.1.5/lib/libordvir8.so: undefined
symbol: __pure_virtual
-

I'm running Zope 2.1.6 with Python 1.5.2 on Linux. DCOracle and
ZOracleDA are both the stab;e releases. Oracle is 8.1.5 (needed the
Setup file from this list).

I added -lordvir8 a couple of times extra to Setup to see if this
problem went away, but it wouldn't.

nm on libordvir8.so says that it contains the __pure_virtual symbol.

Does anyone know how to get around this?

No thats not the same thing. If I have a complex expression for X and it

 Yes it does. "not X" is the array index, 0 or 1.

oic. Thats nasty. Actually you can just write that dtml-var "not X and 'A

You could but this is something I end up doing a lot esp with the way
hyperlinks work. Syntax to help would make it cleaner. It is not to much of
a pollution of the name space as 'always' and 'then' would only be active
inside an if statement.

dtml-var "printCode(CodeToPrint=standard_html_header)" newline_to_br

The advantage of this, is that you can use actual methods (if you're doing
a tutorial). So when you change the method, your documentation updates itself.

If you just want to pass strings into printCode, you can do that too.

dtml-var "printCode(CodeToPrint='dtml-var FunnyVar')"

[Zope] Can't override standard_error_message on NotFound?

2000-06-26 Thread matt

I'm having some problems with standard_error_message on 2.2.0b2.  According to the 
mailing list archives I should be able to override NotFound errors (I even 
cut-n-pasted http://www.zope.org/standard_error_message/view_source into my own 
standard_error_message in case I was missing something) but requesting a nonexistent 
object still gets me what appears to be a built-in page.

Is there something else to do?

[Zope] Bizarre new problem...

2000-06-26 Thread Curtis Maloney


Green things,

I've had a site in development (almost ready to deploy) and in testing for 
some time.  I just went to go through another test run, when a previously 
working page suddenly generated the following error:

Error Type: OperationalError
Error Value: (1017, "Can't find file:
'./service/return.frm' (errno: 13)")

traceback at end of e-mail

I looked at the traceback, and it appeared to be coming from a particular SQL 
method.  I tried testing the method, same problem.  I tried another SQL 
method.  Same again.

Ok, so I looked into it further, and checked a previous install.  I can't 
find ANY *.frm files in either zope tree.

The only event to day which occurred which might have possibly corrupted 
files was when i had to reset due to Netscape (eternal be their pain) chewed 
up all my memory (AGAIN!) and I had to resort to power cycling the computer, 
since it still hadn't responded to my 'kill this annoyingly stupid app' 
keystrokes by the time i'd got back from lunch.

However, on bootup, the fsck did not find any problems on the disc, so I felt 
reasonably safe.


Any ideas?  PLEASE?

Installation:

  RedHat 6.1
  Zope 2.1.6 (from src)

Have a better one,
Curtis.

Re: [Zope] Bizarre new problem...

2000-06-26 Thread Chris McDonough

I suspect this is coming from MySQLdb.  From the Python DB-API spec:

OperationalError 
 Exception raised for errors that are related to the database's
 operation and not necessarily under the control of the
 programmer, e.g. an unexpected disconnect occurs, the data
 source name is not found, a transaction could not be processed,
 a memory allocation error occurred during processing, etc. It must
 be a subclass of DatabaseError. 

.frm files seem to be table data containers for MySQL.  You should try
operating on your database outside of Zope to see if you can reproduce
the problem.
