[Zope-dev] Plain Ice Cream

  Python Function is not quite right, as it is fairly common (for me, at

That's a good point I hadn't thought of :-S

 Function is just as technical as method.  These are OO techncial
 programming terms (function less than method).  The idea is to lower the
 bar for people using Zope.  People who only know HTML will be much more
 likely to grok what a script is than a method.  We want to avoid
 elitism.  Method is total OO elitism, function less so because it's very
 language neutral, and script is like plain vanilla ice cream, everyone
 gets it.

No offence, but I don't think any of the above paragraph holds any
weight.
People who only know HTML won't be writing Python(Method/Function/etc)s
anyway.
I don't think any out of 'script', 'method' or 'function' will have more
meaning than any of the others to these people.
These are just words we're talking about, to the non-technical, it's not
actually going to matter what they are. The main point is to avoid
confusion, especially where words have associated meaning for technical
people. That, IIUC, is why this discussion started in the first place...

 Like chocolate and coconut-shaving covered almonds, technical details
 mixed in with your ice-cream will appeal only to a smaller crowd. 

Vanilla Ice cream gets boring quickly! This ain't a good metaphor for
your argument ;-)

 The new DC documentation motto is "Explain key ideas in simple terms."
 Method is not a simple term.

Can you please make sure this doesn't become 'use less
meaningful/incorrect vocabulary in an attempt to keep it simple, and so
ending up with even more confusing terminology' ;-)

cheers,

Chris

 I can see four potential properties that one could want to emphasize

 1) It is safer (to the Zope server) than a python external method.

 3) It uses python, and not something else as its implementation technique.
 4) In OO terms, it is not really a Method.

Good points :-)

 Hence the preference for Safe in the name.  Even a newbie ought not to
 be able to cut himself too badly on a python method.

I dunno...

 descriptive.  Widget has technical meaning.  Perhaps task or job are
 suitable, as in
 Safe Python Task
 Safe Python Job

Nah, they have too many cron-esque associations. Sounds like things to
be found on a to-do list on in a schedule of some sort.

 Safe Python Subtask

:-(

 Then external methods, which are often also not methods, can become
 Flexible Python Task

Well, felxible doesn't really explain a lot. Filesystem is probably the
most explicit.

I dunno, I actually like Jeff's suggestion of Operation giving you:

PythonMethod- Python Operation
External Method - Filesystem Python Operation

The same could also apply to DTML and Perl Methods. A nice side effect
is that you could have Filesystem DTML Operation replace those horribly
named HTML File objects you get when use grab your DTML out of .dtml
files on disk. Especially as they bypass all known security ;-)

RE: [Zope-dev] Michel's Reply

2000-10-23 Thread Toby Dickenson

 I'm not sure I grok what rightness has to do about it.  I 
 think this is
 right, to me wrong == broken.  This is not broken.

Let me persuade you.

  * someone adds an property named feed to an object at an 
 intermediate
  location in the containment heirarchy. This breaks the cron job that
  calls self.Zoo.Diet.LargeAnimals.hippo.feed(), and all the hippos
  starve.
 
 This is the classic anti-acquisition argument, but it's a red 
 herring. 

I used to believe that too, but no longer agree. I changed my mind after
developing a large application in Zope, and spending alot of time
firefighting the problems that it caused.

 The same argument applies to inheritance; introducing an attribute
 between two classes in a generalized relationship and your app breaks
 and all the hippos starve anyway.

This analogy is false. If a programmer is responsible for a class and it
becomes broken in that way then yes, he is at fault. Fortunately there are
well understood principles for design inheritance relationships to keep this
easy. Each project has a finite number of classes. Each class has
dependencies to only a small number of other classes. Testing (is used
appropriately) can be used to ensure correctness, and this probably means
re-testing each derived class when a base class changes.

The same is not true of a containment heirarchy.

The containment heirarchy is managed by content managers, who are
responsible for content. After adding content they might test that content,
but they are unlikely to retest any functionality - its not their
responsibility.

The containment heirarchy is often large and sprawling. Acquisition-based
bugs occur on a per-instance basis, not per-class, and typically there will
be very many more instances in a system than there are classes. After a
change to an instance there is a need to re-test *every* *instance* below
the change in the containment heirachy. (When was the last time you changed
your root folder? Did you test your whole site?). This makes it impractical
to test them all.



You raised the question of whether this is an anti-acquisition argument or a
containtment-vs-context-binding argument. Please dont misunderstand me;
acquisition is great when used appropriately. However if methods bound to
containement then acquisition could not be used for the purpose you are
demonstrating here.



  Zope cannot be robust against
 programmer error.  Nothing can.

I, as a programmer, develop Zope products. My users install them on their
system.

If your users are programmers then this comment is relevant, but I dont.

Adding a property to an object (using the Property tab in the management
interface) is a user-level operation. I do expect my systems to be robust
against user error.

(Note that it is even possible to 'break' Zope's own management interface by
adding some carefully named properties. Some of those are even WikiNames ;-)


  * someone uses self.Zoo.Diet.buildings.visitor_reception.feed(), and
  ends up filling the reception with hippo food. (This might even be
  possible for someone who has no permissions on the reception object)
 
 This is once again programmer error.

Do you mean the programmer who implemented 'feed'? If yes, Im pleased you
agree with me. Their mistake was to use acquisition instead of inheritance.
If they wanted to use acquistion then they would need to augment their
otherwise simple implementation of 'feed' with either:
1. Explicit security checks (hard to get right)
2. Explicit is_instance checks (inflexible)
3. Accept the fact that anyone granted the 'Feed Hippos' permission on any
hippo may dump hippo feed anywhere, or feed other hippos for which they do
not have that permission.

Perhaps the hippo analogy isnt helping, so heres a more concrete example. In
zope today it is possible for a user who has been granted the 'View
Management Screens' permission in *one* folder to create a one-line dtml
method that lets him see the management page of any other dtml method in the
whole site.

Why? because DTMLMethod's manage_main binds to context not containment.


  * someone uses
  
 self.Zoo.buildings.office.printers.laserjet1.Zoo.Diet.LargeAni
 mals.hippo.feed(),
  and ends up feeding paper to the hippo. (that could even be someone
  who has no other permisions on that hippo object)
 
 This is the same as your first two arguments: programmer error.

(Note: Michel is right that this one is not immediately relevant
  to the binding discussion; its purely a demonstration of a
  misuse of acquisition. Its also a programmer error, but in
  Michel is that programmer)

The real problem here is that you are relying on acquisition from a context
that is not a direct container. Each instance only has one containment
heirarchy. However it has an infinite number of possible contexts, which are
chosen by the caller.

Suppose you have an (apparently correct) external method in Zoo:

def feeding_time(self):
   self.Diet.LargeAnimals.hippo.feed()


[Zope-dev] Security Confusion :-S

2000-10-23 Thread Chris Withers

If anyone can help me with this, it'd give me more faith in the new
security model :-S

Right, I have a Python Product Class (lots of bits left out ;-):

 class MyProduct(OFS.SimpleItem.SimpleItem): 
 """...
 """
 
 __ac_permissions__=(
   ('Use MyProduct' ,('a_method',),('Manager',)),
   )
 
 a_methodisDocTemp=1
 
 def a_method(self,ignored,md):
 list = []
 for name in self.get_contents():
 list.append(DisplayClass(name,self))
 
 return list 

The important bits of DisplayClass look like:

 class DisplayClass(Globals.Persistent):
 """ """
 
 __allow_access_to_unprotected_subobjects__=1
 
 meta_type = 'CaseDisplay'
 
 __ac_permissions__=(
   ('View',('get_name',),('Anonymous',)),
   )

...

 def get_name(self):
 return self._name

Now, I have a DTML method which goes like:

 dtml-with an_instance_of_MyProduct
  dtml-in a_method
   Bdtml-var sequence-item html_quote:/B
   dtml-var get_nameBR
  /dtml-in
 /dtml-with

Which _always_ throws up an authentication box when a_method returns
anything except an empty list. no matter what username or password I
use, that box still appears.

What I would like is for the get_name and a_method methods to be mapped
to permissions so I can manage access to them using the security tab.
How should I do that?

BTW, in an attempt to get the method accessible in _some_ way I have
tried:
- setting __allow_access_to_unprotected_subobjects__=1 in both the
MyProduct and DisplayClass classes.
- setting get_name__roles__=None in the DisplayClass.
- giving every conceivable permission to both the Anonymous and Manager
roles in the folder containing the MyProduct instance

None of which feel like a good way to go, but nevertheless, none of them
worked.
The only way I coudl solve the problem was to give the DTML Method the
'Manager' proxy role, then everything worked fine.
Why is that?
What's _is_ going on?

Confused and Frustrated (isn't that always the way with Zope security?!)

There are several places where Zope is not defending against objects

The most serious possible effect is of terminating a publisher thread.
Fixes for these bugs are bundled into my patches to support Unicode,

RE: [Zope-dev] Reference to a user

2000-10-23 Thread Brian Lloyd

 If I want to store a reference to a User in Zope, what's the best way to
 do it?
 
 I'm currently storing just the user's name, which doesn't seem very
 robust.
 
 Perhaps there's a more conrete reference to the user object? How about a
 path or something?
 Is there an interface for this anywhere? I guess something would have
 been needed for the ownership stuff?
 
 Any ideas gratefully recieved :-)

You might want to look at the 'ownerInfo' method in 
lib/python/AccessControl/Owned.py. That produces a 
fully qualified 'path' to identify a user. It probably 
should be made an interface on the user object itself 
(it probably was done this way initially to avoid forcing 
authors of other user sources to implement a new method 
or be broken).

Huh.  We're looking for something neutral, to connote code that runs in
zope to do some business logic or similar effect.  It should distinguish
the language used to express the logic - perl vs python vs xslt,
etc.  I hate "script", but it occurs to me that the "-let" convention may
be useful:

Python Zopelet
Perl Zopelet
XSLT Zopelet

Zope-specific, runs on the server, shows the implementation language,
won't be confused with non-remotely-editable functions, methods, scripts,

This is the first one with which i'm comfortable - but i may well have

 ...yeah, Zopelet means absolutely nothing, and will just add to

The worse confusion is choosing a name that means something and then either

 o Having to explain that it means different things in different contexts,
   even within Zope.  (This is a bigger problem with the name Method than
   the whole binding issue.  Ditto for script.  Instructing a user to
   write a Python Script will cause a Python programmer to go to the file
   system).

 o Having to explain "it's like ... but different..."  This was apparently
   one of the other problems with the name Method, in that PythonMethods
   (the through-the-web variety) may or may not behave like traditional
   Methods in programming languages.

This is especially bad when the code is Python since Python is also what we
develop in.  Python can now exist in many places in Zope (web, Extensions/,
and Products (disk based)).  External Methods were a nice name in that they
connoted that it was a chunk of code that was external to Zope (at least the
ZODB).  The use of 'method' can come back into issue regarding how they got
bound (ugh), but the External bit fit.  If I was told "write an External
method", I knew what that meant.  When*ever* I hear someone mention writing
a new python method to do something, it has to be qualified with "you mean
in a product\class on the file system or a _PythonMethod_?"

Function, Script..  They all fall prey to the same thing.

Zopelets follows the cute naming of Applet, Servlet, Scriptlet...
(IE has Scriptlets).  I'm not advocating it entirely, but it follows a nice
silly tradition in a way that is explainable - small chunks of Zope code
managed through the web.  And they happen to be in Python. (or could be
predicated by the language of choice).

[Zope-dev] (no subject)

2000-10-23 Thread Spicklemire, Jerry

Hi Name Hunters,

My problem with Zopelet is that it already has a meaning, at least to me. 

Looking down the road, not nearly as far as one might imagine, let's see
where we may be heading. Think about minimal Zope instances running on Palm
Gizmos, Cell Phones, whatever, a sort of personal ZEOClient, that enables
offline or intermitent access to Zope Applications (e.g. WorldPilot). That's
a Zopelet to me, a "little Zope".

As for the other suggestions, "Op" sounds right to me. An Operation, or an
Operative carrying out some work on behalf of the caller. 

Python Op, Perl Op, XSLT Op. It's short too!

Also, Safe is clear, and easy to grasp, since most folks are aware how
critical security can be. As for Flexible vs. UnSafe, how about "Direct", as
in, "running directly from the file system"?. The term implies a trade-off
of power for some degree of insecurity, at least to the initiated. Newbies
should be warned away if they don't get the connotation.

This leads to:

Direct Python Op, etc.

[Zope-dev] ZCatalog + ZCatalog

2000-10-23 Thread Casey Duncan

I am making it my mission to enhance the beast that is ZCatalog. This is the
first of many improvements I hope to make to it as time goes on.

DISCLAIMER
This patch has only been moderately tested, and all side affects are not
known. I am submitting it here for review before adding it to the collector.
You take full risk in using this patch on your installation.
/DISCLAIMER

OK, what this patch does is allow you to concatenate ZCatalog result
sequences (Lazy sequences) without loading the whole enchilada into memory.
It also dispenses with the funky workaround/hack notation that currently
exists (although it still works AFAIK). Once this patch is in place, you
will be able to write code as follows:

dtml-in "Catalog(args)+Catalog(other args)+..."
   ...
/dtml-in

or even:

dtml-in "Catalog1(args)+Catalog2(args)"
   ...
/dtml-in

The latter might be useful for dealing with ZCatalog scaling issues, or
combining completely objects from entirely different locations.

The patch changes Lazy.py and Catalog.py (very slightly). These files can be
found in your {Zopedir}/lib/python/Products/ZCatalog directory.

Add the following code into the Lazy class definition in Lazy.py. I added it
at the end following line 118 (slice=__getslice__):

def __add__(self,other):
# Concatenate result sequences together while remaining lazy

# Make sure the object we are concating is also Lazy
try:
if other.__class__.__bases__[0].__name__ != 'Lazy':
raise TypeError, """Cannot concatenate objects. Both
must be lazy result sequences (ie ZCatalog results)"""
except:
raise TypeError, """Cannot concatenate objects. Both must be
lazy result sequences (ie ZCatalog results)"""

if self.__class__.__name__ == 'LazyCat':
# Don't nest LazyCat objects unnecessarily
if hasattr(self,'_seq'):
seq = self._seq
else:
seq = [self._data]
else:
seq = [self]

if other.__class__.__name__ == 'LazyCat':
# Don't nest LazyCat objects unnecessarily
if hasattr(other,'_seq'):
seq = seq + other._seq
else:
seq = seq + [other._data]
else:
seq = seq + [other]

return LazyCat(seq)

The change to Catalog.py is a single line as follows:

Change line 603 (if not r: return r) to:
if not r: return LazyCat(r)

The change to Catalog.py prevents empty catalog search results from throwing
an exception when concatenating it with a non-empty search result. This is
the only part that I see as a risk to break existing code. If you, for
whatever reason, relied on a ZCatalog returning an empty list ([]) when the
search came up empty, your code will no longer work. Here is an example:

dtml-let result="Catalog(args)"
dtml-if "result == []"--- This no longer works
   ...
dtml-else
   ...
/dtml-if
/dtml-let

However this still does:

dtml-let result="Catalog(args)"
dtml-if result
   ...
/dtml-if
/dtml-let

And this does what you expect of it when both searches come up empty:

dtml-in "Catalog(args)+Catalog(other args)"
   ...
dtml-else
   ...
/dtml-in

IMHO this is a very minor side affect, and well worth the gain.

Please scrutinize this patch and pick it apart and let me know what works
and what doesn't or if I've missed something.

Enjoy,
Casey Duncan

 Is there a Wiki or some other starting point for this thread. As a

 It's nice to know that I can start out learning in a safe mode and 
 then graduate to a power mode after learning more. Is there a 
 ZopeScript and why not? Safe ZopeScript can be written in using other 
 scripting languages.  Zopelet imho is not as marketable as ZopeScript.

OK, this is the problem.  There are several ways of writing executable
code available to other objects in Zope.  One is the Python Method.
It is available from http://www.zope.org/Members/4am/PythonMethod

From 4am's page:
PythonMethods will not allow assignment to an attribute, element, or slice. 
No "del" is allowed.  Names starting with "_" are not accessible. Import 
is controlled. Globals all live in a private namespace.

There is a proposal to call this construct a Zope Script.  And your
message is exactly the ammunition I wanted.  Thanks!

The other way to script in python is currently called an External
Method.  Since perl is being added as a Zope scripting option, this
will clearly have to be renamed, as well.  External Methods have none
of the restrictions of PythonMethods.  This makes it quite easy to escape
all Zope security, to crash Zope, and to do other nasty things.  Needless
to say, Zope hosting sites do not generally provide External Methods.

There is no ZopeScript, and probably never will be.  What would
ZopeScript do?  Would it be a construct like JavaScript that was
executed on the client's computer?  If so, every browser vendor would
have to support it.  This is unlikely, to say the least.

Is it server side?  Then DTML, PythonMethods (to be renamed), PerlMethods
(which don't exist yet), External (Python) Methods, External Perl Methods
(which also don't exist yet) give plenty of scripting options, without the
need for another language.

It is not at all clear that Safe scripting methods (in the strong sense
meant here, meaning that it can neither damage the client nor the 
server), can be written in languages other than Python (I have
heard some doubts expressed about perl).

And, there is generally no need to "graduate" to external (power)
methods.  You only need to use an external method when you need a
module not imported by Zope (not available through the _ namespace).

So, you have written several things in your message that really
bolster my dislike for both zope script and power as terms.
1) You have gone from the word Zope Script to a separate language
ZopeScript in a single bound.  2)  You have assumed that you will
want to "graduate" from Safe Methods to "Power" Methods (You don't,
external methods are last resort options).  3)  "Power" methods
don't require a lot more learning than Safe Methods.  You have
to learn what modules are available, but you are using the same
language in either case!

Maybe my suggeston of flexible is to weak.  Maybe they should be
Escape Hatch Python Operations (Escape Hatch Python Zopelets)!

   When you call it operation, method, or function it takes it away 
  from it's context.  This is zope specific right?  Excuse me while I 
 use safe ZopeScriptPython or power ZopeScriptPerl.

Not really Zope specific in the sense you mean.  It is an object (not
in the OO meaning) that can be called from a Zope site.  But the 
language is pure Python (perl), with no modifications, and usually
can be snipped and executed outside of Zope.

[Zope-dev] Unit testing, ZUnit

2000-10-23 Thread Lalo Martins

We (I and Hiperlógica) started to develop a Product we called
ZUnit, intended for XP-style unit-testing Python-based
Products in a full Zope environment (with a real ZODB, REQUEST,
RESPONSE, etc).

We first conceived it as a kind of Zope-based version of
unittestgui.py - you create a "TestRunner" object giving it the
package, module and name of a TestSuite object generator (see
the PyUnit documentation) and inside it you may click on some
widget to run the tests and produce a "TestResult" object which
you can inspect later. Does this sound like a good design?

Then I figured in the long run a Product isn't the best
sollution; instead, fiddling with App/Product* sounds more like
it, to allow developers to register tests just like they
register classes, ZClass superclasses, _misc and help. Of
course, just like the current registerHelp and others, it
wouldn't be mandatory and not using it wouldn't break anything.

Then, in the Product's page in the Control Panel, there would
be a tab "Test", where you'd be allowed to run the unit tests.

What do people think of this? What does DC think of this? Can I
go ahead and develop it in this direction?

(I will create a proposal in dev.zope.org, but I want to get
some feedback here first to flesh out the proposal a little
more.)

 Chris . o O ( what the hell is a Zopelet? ;-)

I have to say that I don't like Zopelet either.

I guess nobody else likes my 'Blocks' nomenclature:

Python Blocks
Perl Blocks
DTML Blocks

As I mentioned before, I tend to use DTML Methods in two
contexts:

- as Views on objects (Templates)
- as building blocks for Views

In one context (Views/Templates), the DTML method is meant
to be accessed directly through the web. In the other
context (Block), the DTML method is only ever accessed by a
View.

I would actually like to have a Block object that is not
directly accessible, without having to go through some
proxy-role rigamarole.

Something else to consider for these two Use Cases of
DTML/Python/Perl Methods/Blocks/Scripts, is that typically
only the Block Use-Case is expected to be re-used through
recomposition, as well as acquisition, while Templates/Views
are usually re-used through Acquisition only.

I'm not sure this has any impact on the 'Method Binding'
argument floating around, but I thought I'd mention it again
in that context.

[Zope-dev] The Great Python (and Perl) Method Renaming Poll

2000-10-23 Thread Michel Pelletier


We will be conducting a community poll to decide what to call Python
(Perl, insert your language here) Methods.

Many candidates have been discussed, but I'm afraid I don't have enough
time to cull all the candidates from the discussions.

So, before the poll, we are calling for nominiations from the
community.  Please send me an email containing one or more candidate
names.  These names will be added to the list.  No pre-screening will be
done, so please exercise some discretion if your favorite name is more
tounge-in-cheek than practical (you never know what the masses will
decide though!).

Later this week, I will create a web poll where you can vote for your
favorite.

thanks,

-Michel

RE: [Zope] NEWBIE: assign next free ID automatically

2000-10-23 Thread Max Møller Rasmussen

This is untested, but an idea:

dtml-in "objectValues()[:-1]" sort=id reverse
dtml-call "REQUEST.set('new_id', id+1)"
dtml-var new_id

It is still subject to failure if 2 or more processes are writing an article
in the same time.

Furthermore it has to find and sort all the items in the folder. That could
take a long time if there are lots of them.

Maybe you should somehow insert a dtml-try until you succed in writing the
article.

Another aproach would be to have the folder with your articles have a
property "lastID" and let "nexID" be a method that automatically would
increment lastID end return it.

Maybe it is possible to lock the lastID property??

From: Patrick Koetter [mailto:[EMAIL PROTECTED]]

What is it that I want to do?
I want to evaluate the highest ID (all are 'int') within the folder and
assign the next highest.
I'm sure this is easy to you...

Re: [Zope] Problems with mysql and sql methode

2000-10-23 Thread Oliver Bleutgen

 MySQL is case-sensitive over table names, so MERCHANTPAYMENT is not the
 same as merchantpayment.

 Other databases (Postgresql, Informix) are not.

 Perhaps the Access/ODBC interface hides the case-sensitivity while the
 direct ZMySQLDA does not ?

Hmm, I'm not very clear about differences between handling of (table, column) names
in sql-databases, but postgres IS case sensitive (in some sense).

Few days ago I wrote to messages to this list describing my problems
with postgres and capitals in column-names. The handling of these will
render dtml-sqltest .. useless, because it doesn't quote the name of the
vars. I that case postgres will not respect capital letter (will turn them
lowercase) but also won't find the column which name is written uppercase.
 
I think it would be usefull to collect the behaviour of different databases
and try to find a solution which will work with all of them.
The solution we have now clearly doesn't do that.

cheers,
oliver

see) ? In Apache one has to put a .htaccess file in the directory.

  - how to limit the size a folder ? I want to give login to friends 
so they can add photos in a folder but I don't want to receive

[Zope] GET requests in Medusa web server

2000-10-23 Thread Sean McGrath

Hello all,

Why does the Medusa server in Zope not handle GET requests which specify
a full URI? For example, if I have a web server running on web.mydomain.com,
and I want to get a file called "file.html", doing a GET request of the form

GET http://web.mydomain.com/file.html HTTP/1.1

gives me a 404. Doing a GET of the form

GET /file.html HTTP/1.1

works fine. If I understand RFC 2068 correctly, a HTTP 1.1 compliant server
is expected to handle both cases (5.1.12 of RFC 2068), although HTTP 1.1 
clients
are not supposed to generate these unless talking to a proxy. In our case, the
software which generates the request is a WAP gateway (Ophelia, 
http://www.3ui.com),
and it always assumes it is talking to a proxy server, and requires a code 
change
to change it. I've tested Apache and IIS with this, and they handle both forms.

Thanks in advance.

Well I'm confused !!!

I have two databases , one MySQL (3.23.25) one PostgreSQL (7.01), both with 
the same schema. Both have a table 'artist'. The following SQL Method (Zope 
2.2.1) works with both

select a.artist_id,a.known_name,a.initials
from artist a
where dtml-sqltest surname type=string

Change this to

select a.artist_id,a.known_name,a.initials
from ARTIST a
where dtml-sqltest surname type=string

it still works with PostgreSQL but with MySQL I get

"Table 'tunedb.ARTIST' doesn't exist"

Change this to

select a.artist_id,a.known_name,a.initials
from ARTIST a
where dtml-sqltest SURNAME type=string

Then it still works with PostgreSQL, provided you also change the argument 
to the SQL Method from surname to SURNAME.

When you click on the Test tab of an SQL Method it shows the SQL generated 
and you can see, in the above example, that the uppercase words are passed 
through unchanged to the database

viz.

select a.artist_id,a.known_name,a.initials from ARTIST a where SURNAME = 
'Molloy'

In what circumstances is PostgreSQL case-sensitive ?

 Hallo,
 I've got a question concerning versions.
 The working with versions in the management screen is obvious to me, but
 what about hiding the management-screen and working with them.
 I want to add ZClasses programmatically but some users should only be able
 to add them after a Controller has checked that everything is o.k.
 What are the right methods to use???

Re: [Zope] Problems with mysql and sql methode

2000-10-23 Thread Oliver Bleutgen

 At 09:41 23/10/00, you wrote:
Hmm, I'm not very clear about differences between handling of (table,
column) names
in sql-databases, but postgres IS case sensitive (in some sense).

 Well I'm confused !!!

 I have two databases , one MySQL (3.23.25) one PostgreSQL (7.01), both
 with
 the same schema. Both have a table 'artist'. The following SQL Method
 (Zope
 2.2.1) works with both

 select a.artist_id,a.known_name,a.initials
from artist a
 where dtml-sqltest surname type=string

 Change this to

 select a.artist_id,a.known_name,a.initials
from ARTIST a
 where dtml-sqltest surname type=string

 it still works with PostgreSQL but with MySQL I get

 "Table 'tunedb.ARTIST' doesn't exist"

 Change this to

 select a.artist_id,a.known_name,a.initials
from ARTIST a
 where dtml-sqltest SURNAME type=string

 Then it still works with PostgreSQL, provided you also change the argument
 to the SQL Method from surname to SURNAME.

 When you click on the Test tab of an SQL Method it shows the SQL generated
 and you can see, in the above example, that the uppercase words are passed
 through unchanged to the database

 viz.

 select a.artist_id,a.known_name,a.initials from ARTIST a where SURNAME =
 'Molloy'

 In what circumstances is PostgreSQL case-sensitive ?

First, sorry for my (nearly) full-quote, but I think it makes this discussion
more readable.
To your question, from my testing (I did this with column names only, but I 
suspect the same behavior for table-names), postgres is case 
sensitive, but - as I wrote - in another sense.
If you don't quote the column-names, they are converted to or interpreted as
lowercased names. _But_ if the real name of the table/column is _uppercase_, 
it will not be matched by this lowercased name - in this sense postgres 
is case-sensitive.
Postgres needs quoted names in sql-queries to respect capitalization (sp?) -
and I couldn't dtml-sqltest ... get to generate them.
This was a major problem for me, because I had to work with a bunch of tables
which were exported from foxpro and dbase, and their names were uppercased
in the process.

cheers,
oliver

[Zope] Almost there, but I am still having a little problem

2000-10-23 Thread Taco Scargo

Thank you all for helping me out. The hints got me almost there. I have one
unsolved mystery left. What I am trying to do is print the titles from the
DTML Documents in the 'artikelen' folder (and actually another property
called 'inleiding'. I believe the code below should do this, but it does not
work. It returns 'Zope' instead of the title. If I use the 'inleiding'
property it reports that it does not exist. If I just use sequence-item it
returns the complete item ok.

Any clues ?

Thanks,

Taco

[Zope] again: install Zope under Solaris 8

2000-10-23 Thread Jan-Thies Baehr

Hi,

I just want to resume a thread from september. Has anyone else
encountered problems installing Zope (in our case 2.2.2) under Solaris

[Zope] Zope 2.2.2 breaks YihawDirectory ?

2000-10-23 Thread Wolfgang Strobl

When installing the actual Version of YihawDirectory
(http://www.zope.org/Members/Roug/Yihaw) by importing it into a 
2.2.2 Zope, I got the following traceback. This happens both with 
and without the current hotfixes.

Importing it into 2.2.1 equipped with the current hotfixes works 
without flaws. Any ideas what's going on  here? I don't want to go 
back to 2.2.1  :-/

[Zope] Updating auto incrementing counter in a propertysheet

2000-10-23 Thread Max Møller Rasmussen

What am I doing wrong here ... please !!

I am trying to make an autoincrementing counter for use in a diskussion
forum. It's purpose is to autogenereate id's for new messages.

It is important that the id's are in order, so I need to make them this way.

I have a zClass (objectmanger) with a property called "lastID", on a
propertysheet called "hidden".

I have then written a dtml mehtod that should return the id incremented by 1
and then sets the lastID to this new id.

the dtml for the "newID()" dtml method looks like this:
--
dtml-call "REQUEST.set('new_id', lastID+1)"
dtml-call "REQUEST.set(lastID, new_id)"
dtml-return "_.int(new_id)"
--

When I try to get the property directly via the browser i get a result of
"1" The default value for lastID=0 to begin with so this sounds plausible,
but when I refresh the browser nothing happens. So I guess that lastID isn't
updated in the above code.

How do I do that?

Also when I the try to insert "newID()" in my "mxm_comment_add" method in my
zClass, to autogenerate numbers, like this:

dtml-with "mxm_comment.createInObjectManager(newID(), REQUEST)"

I get the following traceback: (And I would expect it to run at least 1 time
with "1" as a new id.)

hi steve.

one of the worst things with zope sendmail is that you cannot indent
things the way you might with clean coding use.  but, you can use some
very nice sql calls within you sendmail, including appropriate
indentation.

below is a sendmail method that i use to read a string of email address
from a mysql database, and the text of the email from a second database,
which gets parsed via an external python script (to parse the string of
text into lines of = 75 chars, otherwise the text gets sent as single
lines).  also, it checks for non-existent email addresses or missing
names (the database is a list of people and companies, whether connected
to the net or not).

it may not be the most efficient, but it works; and any suggestions as
to making it more efficient will be most appreciated.

ciao!

If you are in the Zope directory, since most uni(x)es don't have the current

RE: [Zope] GET requests in Medusa web server

2000-10-23 Thread Brian Lloyd

 Why does the Medusa server in Zope not handle GET requests which specify
 a full URI? For example, if I have a web server running on 
 web.mydomain.com,
 and I want to get a file called "file.html", doing a GET request 
 of the form
 
   GET http://web.mydomain.com/file.html HTTP/1.1
 
 gives me a 404. Doing a GET of the form
 
   GET /file.html HTTP/1.1
 
 works fine. If I understand RFC 2068 correctly, a HTTP 1.1 
 compliant server
 is expected to handle both cases (5.1.12 of RFC 2068)
 ...

Hi Sean - 

What version of Zope are you seeing this with? I seem to 
remember fixing something along these lines fairly recently. 
Is it still the case in Zope 2.2.2?

[Zope] argument type of list for ZSQL ?

2000-10-23 Thread Brian Withun


Is it possible to create a ZSQL
Method which has a list-type as
an argument?  ..something that
might support a call like this
(or similar):

dtml-call expr="populate_department(dept_id=200,
dept_member_ids=[22,150,89])"

where inside the ZSQL Method I
might iterate over dept_members

dtml-in dept_members
  INSERT DepartmentMembers ( department_id, employee_id )
  VALUES ( dtml-sqlvar dept_id type=int, dtml-var sequence-item )
  dtml-var sql_delimiter
/dtml-in

If this can be written as shown
(or similar) what would be the
syntax used to populate the
'dept_members' field on the TEST
view of the ZSQL Method? Would
it just be:

dept_member_ids:
 ---
 | [22,150,89] |
 ---

or

dept_member_ids:
 ---
 | "[22,150,89]"   |
 ---

or

 ... ?

Re: [Zope] Updating auto incrementing counter in a propertysheet

2000-10-23 Thread Andy McKay

[..]
 When I try to get the property directly via the browser i get a result of
 "1" The default value for lastID=0 to begin with so this sounds plausible,
 but when I refresh the browser nothing happens. So I guess that lastID
isn't
 updated in the above code.

I think this is a class - object problem. Each time you create an object
based on your ZClass, the lastID becomes 0. Each object has its own lastID,
rather than what you are expecting which is one instance of last id.

My advice... download and install FSCounter from Zope.org
(http://www.zope.org/Members/andym/FSCounter)

Add an FSCounter, call it "Unique" and turn Cookie? to OFF (very important).
This will generate and keep track of an incrementing value on the file
system

Then in your constructor add / change:

dtml-let u=Unique
dtml-call "REQUEST.set('unique', u)"
/dtml-let

dtml-with "mxm_comment.createInObjectManager(_.str(REQUEST['unique']),
REQUEST)"

That should work like a charm.

[Zope] Lost External Methods

2000-10-23 Thread Robert_J_Roberts

I am running 
Zope 2.1.4 (binary release, python 1.5.2, win32-x86)
Python version: 1.5.2 (#0, Jul 30 1999, 09:52:18) [MSC 32 bit
(Intel)]
System Platform: win32 
I have several external methods.  Just recently, they started to be good for
one run only.  The external methods run fine once.  The next run, they error
out with: "Could not execute external method: ExtMthdName"  If I reload that
method [Edit button it] it runs fine again for one run.

Any suggestions?

And... while I'm at it, is there a way in Zope to programmatically reload
[Edit button] an external method (in case I can't get the problem to go away
and just out of general curiosity)?

You could also do (and I would recommend it) by using the security system
Zope give you. For example if you go to your root zope folder, click on
security and deselect View for Anonymous User, this will have the same

[Zope] overriding manage methods

2000-10-23 Thread Robin Becker

In my Z-Class I would like to hook various standard methods in a dtmlish
way.

The frame work would call my dtml method say manage_delObjects and
within that method I would like to call the original manage_delObjects.

I guess this must be a very standard requirement as I see that there are
methods called afterAdd and beforeDelete etc in the object manager. I
just don't know the proper namespace magic to override and eventually
call these.

[Zope] A ZClass for LaTeX documents

2000-10-23 Thread John Verzani

Hi,

I've been using a ZClass for LaTeX documents that I put together in a
manner very similar to the one described in making a ZClass for STX
documents at http://www.zope.org/Members/tseaver/STX_Document I like
to mark things up in LaTeX as I can type it faster than HTML, I can
create very nice printouts in PDF or PostScript and there is a nice
renderer into HTML called tth.

There are a few annoyances that I would like some help on.

* I am using tth (http://hutchinson.belmont.ma.us/tth/) which can
  convert LaTeX into HTML quite well. In order to do so, when
  uploading the tex file or changing the tex file, I call tth and
  store the HTML along with the tex source. My DTML for this is

dtml-if uploaded_body
  dtml-call "REQUEST.set('body_tex', uploaded_body )"
/dtml-if
dtml-if body_tex
dtml-let body_html="PARENTS[-1].SiteMethods.tth(body_tex)"
dtml-call "REQUEST.set('body_html',body_html)"
/dtml-let
/dtml-if

dtml-call "propertysheets.Basic.manage_editProperties( REQUEST )"
dtml-call reindex_object

  Which if there is a new file upload stores it in body_tex, and then
  takes body tex and run tth on this to create the body_html. 

  When I do this though, the tth is called on the old body_tex data, not 
  the recently stored one. Because of this, I have to change the file
  twice. 

  Any ideas as to why and how I can fix this? My guess is
  subtransactions, but I don't know how to fix that. 


* Ideally, I would like to be able to call the latex file this way
  dtml-var latex_filename fmt=tth 

  (or even better just as dtml-var latex_filename) 

  where tth is a method which takes a latex document and returns
  HTML. I couldn't figure out how to do this though. How does one go
  about defining new format methods for ZClasses? I would imagine it
  isn't hard, I just need to know where to look.

* If that isn't too hard, I would also like to know how to make this
  an option for markup in SquishDot. I have a math class using this as 
  a discussion board, and it would be nice to let them use basic LaTeX 
  for math markup.

Thanks for any pointers.

John Verzani

"ZPublisher/Test.py" with the "-D" option.

Usually, I do not use it this way, however, as
it takes too long, before I reach the interesting
point. Instead, I use:

import pdb; pdb.set_trace()

at the point in Python code, where I want to get control.
Then I use "Test.py" without "-D".

[Zope] newbie question

2000-10-23 Thread Kathy Hester






Hello and thanks for your patience!I am beginning to learn zope. I am going through the tutorials in the book. I have run into a problem creating an external method.I know I must be doing something stupid!I have my addEntry.py saved in the Extension folder in the Zope folder as it installed it (i'm in win 2k). I have the dtml method to call addEntry.When I try to add an external method id/function name/file name are all addEntry. (Supposedly to keep me from messing up...). I get this error message- Zope has encountered an error while publishing this resource. Error Type: SyntaxError

Error Value: invalid syntax

Troubleshooting SuggestionsThe URL may be incorrect. The parameters passed to this resource may be incorrect. A resource that this resource relies on may be encountering an error. For more detailed information about the error, please refer to the HTML source for this page. If the error persists please contact the site maintainer. Thank you for your patience. There must be a simple solution. I have looked at the o'reilly book/on-line docs/how tos and I am still not seeing my error. Please feel free to e-mail me directly at [EMAIL PROTECTED].I thought I had found a work around by installing python method  but I am not sure what I need to put in the parameter list.

[Zope] Cookie problem with IE5, 5.5, ...

2000-10-23 Thread Menard . Jean-Francois

I developped a toggle button to let the users hide/show the menus.

I use a cookie to store the current value.  The code I use is:

dtml-if "State=='ON'"
  dtml-call "RESPONSE.setCookie('affmenu', '1')" 
dtml-else
  dtml-call "RESPONSE.setCookie('affmenu', '0')" 
/dtml-if
/head
dtml-call "RESPONSE.redirect(Retour)"

in a dtml method.  It works great in netscape, but not in IE 4, 5 or 5.5.
Why???

I know I could use a session product, but I'm worried about session
expiration.  Could I set one of these products to expirate ***only*** when
the browser is closed?

And, why a session variable doesn't exist?  It's the ONLY thing I miss from
ASP...

[Zope] AW: [Zope] a problem with 'start' command

2000-10-23 Thread Patrick Koetter

Hi Gaby,

I am not on of the zope-gods on this list, but there is something in the
message that you sent that makes me stop and think:

IOError: [Errno 49] Disc quota exceeded

I believe the problem is not zope itself, but the amout of diskspace that
you or the user 'pecos' is allowed to use in the dir /home/pecos/...

Why this?
Something, I presume it's the "quota daemon" of the "solaris-machin" that
you are working on, tells your zope, that the 'Disc quota exceeded'.

So what to do about that?
1. get rid of files you don't need anymore -- try to start zope
2. ask your sysadmin to give you more diskspace. this can be a hard one
;-) -- try to start zope

I'm sure that after you've solved this problem, you are going to run into
'zope-problems' ;-)
Try to go for the Zope Book online http://www.zope.org/Members/michel/ZB/.


gruezi ;-)

 Phil,

 thanks for your suggestion, i understood it

  If you are in the Zope directory, since most uni(x)es don't
 have the current
  directory in the path, you need to start zope with './start'.

 but now when i execute the command i have the following message:

 what does this message mean ? what can i do ?

 in fact, my problem is when i tried to execute
 "localhost":8080/pecos/ where i have the information i need, there seems
 to have problems, because the connection is not possible.
 first thing i thought is just to try to start the server again, but i can
 not.

 thanks for any help

 have a nice evening.

The way we run it at work is to use ProxyPass in Apache.  Check your Apache

Re: [Zope] Updating auto incrementing counter in a propertysheet

 What am I doing wrong here ... please !!
 
 I am trying to make an autoincrementing counter for use in a diskussion
 forum. It's purpose is to autogenereate id's for new messages.
 
 It is important that the id's are in order, so I need to make them this way.


Is it more important that they be in an order, or that they be in a
specific sequential list?

For example, an id based upon time stamp would indeed provide IDs that
re orderable (thus handling the in order part). While a list od IDs
named 1,2,3,4... is more like a 'linked list', where you know what
follows and what precedes a given id. 

However, by using objectIds, you can obtian a list of ids in a given
object (folder), and thus provide one for yourself, if needed.

FTR, I have implemented both ways of doing it. I am leaning towards the
timestamp as being more effective,  simpler.

Greetings! Great to have yet another Zope follower; hopefully you will
decide to stick with it... Just be patient, you will find out that after a
solid month of using Zope that is has never ending power (thanks to
python and the awesome coders at digital creations).

You can use ProxyPass (mod_proxy) or Rewrite (mod_rewrite) to communicate
with Zope from Apache. This basically creates a "tunnel" between Apache
and Zope, and data gets exchanged between the two.

Some people find that ProxyPass doesn't work for them, so Rewrite is great
as well (I personally use Rewrite because it suits my site). Confer with
www.zope.org, or come to #zope on irc.zope.net with an irc client.

[Zope] One last request

2000-10-23 Thread Taco Scargo

I have one unsolved mystery left. What I am trying to do is print the titles
from the DTML Documents in the 'artikelen' folder (and actually another
property called 'inleiding'. I believe the code below should do this, but it
does not work. It returns 'Zope' instead of the title. If I use the
'inleiding' property it reports that it does not exist. If I just use
sequence-item it returns the complete item ok.

Any clues ?

Thanks,

Taco

Re: [Zope] Updating auto incrementing counter in a propertysheet

 I have a zClass (objectmanger) with a property called "lastID", on a
 propertysheet called "hidden".
 
 I have then written a dtml mehtod that should return the id incremented by 1
 and then sets the lastID to this new id.
 
 the dtml for the "newID()" dtml method looks like this:
 --
 dtml-call "REQUEST.set('new_id', lastID+1)"
 dtml-call "REQUEST.set(lastID, new_id)"

In the above line --- do you want to set up new value for ZClass property,
isn't it ?
If so, you have to use manage_changeProperties method of property sheet.

[Zope] Adding many instances at once

2000-10-23 Thread hohage

Hallo,
how can you add many ZClass-instances at once.
I mean with the correct content,title and other properties.The example(adding 
zclass to a zclass)is always adding one class.The next problem is how to deal 
with the properties in a form if you don't know how many items are added by 
the user??
User A is adding three news-items at once, the next is adding 5.

[Zope] The Great Python (and Perl) Method Renaming Poll

2000-10-23 Thread Michel Pelletier


We will be conducting a community poll to decide what to call Python
(Perl, insert your language here) Methods.

Many candidates have been discussed, but I'm afraid I don't have enough
time to cull all the candidates from the discussions.

So, before the poll, we are calling for nominiations from the
community.  Please send me an email containing one or more candidate
names.  These names will be added to the list.  No pre-screening will be
done, so please exercise some discretion if your favorite name is more
tounge-in-cheek than practical (you never know what the masses will
decide though!).

Later this week, I will create a web poll where you can vote for your
favorite.

thanks,

-Michel
