[Zope-dev] How does a subclass call its ancestor's method in zope?

2001-01-10 Thread Dirksen

Here is a ZClass testa, with a dtml method 'do'. Its subclass testb
overrides do. How does testb call its ancestor's 'do'? In python, it can be done as
'testa.do()', but what's the equivallent in zope?

Re: [Zope-dev] ZCatalog and 'fuzzy logic'

2001-01-10 Thread Morten W. Petersen

 I do not think that "fuzzy logic" is strongly related to "regexp-like".
 Anyway.
 
 Fuzzy searching often means "finding matches with characters omitted,
 replaced or inserted".

It seems I misunderstood the term fuzzy logic myself.  Fuzzy logic means
if I search for a word, for example 'programmer', it will return matches
to the words 'program', 'programming','programmable' etc.

I.e., it will somewhat intelligently return words that are similar in
what they mean, using grammar rules (chopping off endings of words and
making them match others).

Hmm.

Cheers,

Morten

[Zope-dev] AUTHENTICATION_USER in standard_error_message cause by NotFound error

2001-01-10 Thread Tim Ansell

newbie alert

Hello.

I've been using zope for a couple of months, i have found zope to be a
great product and thank you for creating it. Currently i have run into a
problem, i need to access the AUTHENTICATED_USER in a
standard_error_message called by notFoundError in BaseRequest.

I was wondering if the authentication routine can be added before the
authentication routine in BaseRequest? Or if this is not possible it
could be split into a function and and call it before the notFoundError
call as well?

There are many reasons you might want to do this, i have listed some
below:

* You want list possible urls the reader could have meant but don't want
to show let Anonymous users see possible privileged urls

* You want to provided different error messages for different people,
i.e. a more advanced error for coders, a simple error for html writer, a
special error for normal people

* You wanted errors to only be reported it they where caused by certain
users

and the list could go on

Yup, this allows you to alias your_attribute to _v_your_attribute without
creating an attribute that *will* persist in the process.

 Hmm... more questions:
 
 If I do:
 
 x = MyClass()
 x.your_attribute = 1

your_attribute is set to one instead of the ComputedAttribute instance and
concequently persisted. If you want _set_your_attribute to be called, you
need to override __setattr__:

def __setattr__(self, name, value):
setter = getattr(self, '_set_' + name, None)
if setter:
setter(value)
else:
raise AttributeError, "no such attribute: " + `name`

 Where do you import the ComputedAttribute module from?

from ComputedAttribute import ComputedAttribute

The same way you call any overridden method, by calling it on the class
you inherit it from.

So:

  class Foo:
  def __setattr__(self, name, value):
  # Whatever
  pass

  class Bar(Foo):
  def __setattr__(self, name, value):
  Foo.__setattr__(self, name, value)

[Zope-dev] Security Machinery doesn't work on some objects?

2001-01-10 Thread Chris Withers

Hi there,

I'm slightly confused by a class I have:

class X(Persistent, Acquisition.Explicit):

This class has no __roles__, no __ac_permissions__, no nothing...
Instances of this class are stored within a special folderish class, Y.

This folderish class has a __bobo_traverse__ which returns X objects,
wrapped in context, from it's self._xs BTree using something along the
lines of:

def __bobo_traverse__(self, REQUEST, name):
ob = getattr(self, name, _marker)
if ob == _marker:
ob = 
return self._xs[name].__of__(self)

Now, it appears no methods or other attributes of this class are
protected by the security machinery, even though the instances involved
are wrapped. The DocString stuff still applies but, once a method has a
docstring, any anonymous user who can traverse to one of these objects,
can execute any method (attributes whinge about a missing docstring, how
bizarre, attepting to traverse to __init__ complains the method starts
with a _ ;-) of that instance which is more than a little disturbing ;-)

I thought Zope's security policy had changed to be disallow by default,
but that really doesn't seem to be the case here :-S
What am I missing out on? Is there some mixin class I need or something
I need to acquire to make the security machinery check these objects?

confusedly and worriedly,

Chris

[Zope-dev] New UI for 2.3

2001-01-10 Thread Steve Alexander

I think the new UI for 2.3 is great improvement over 2.2.

I'm already finding the sorted tables of folder contents useful, and 
having the add new items select at the top saves time.


However, I do not like the 3-frame interface. I feel that the top frame 
is wasted space. The Zope logo and "Logged in as username | Logout" 
could as easily go at the bottom of the tree-view frame on the left. 
This would leave extra screen space for doing work.

I realize that I can make the frame smaller by dragging it with my 
mouse. I do a lot of TTW development, and I think I might find that 
cumbersome, so I guess I'll be hacking the top frame out of my 
management interface :-)

I also much prefer blue to black as a background colour for the tabs and 
the "Root Folder" link. The black seems a bit overbearing.

 that did the update. Your next request may get a different
 thread and see a different value.

Huh?

If I change self._v_your_attribute it's only going to get updated in one

That's a bit sucky :-S

This, usually, is called "stemming".
Though, your examples indicate quite a strong form of it.

If you have some tool, maybe LinguistX, that map from a word
to its stem and then from the stem to all words with this as
stem (or directly give the stem equivalence class of a word),
then it is quite easy to incorporate that in Zope's catalog.

However, to do that cleanly, you will need good algorithms
and/or large dictionaries. This, usually, is not free of
charge.

Re: [Zope-dev] ZPatterns, ZClasses, Specialists: Assigningresponsibilities

At 05:13 PM 12/21/00 +1100, Itai Tavor wrote:

I think you're right about this being an OrderLineItem.  A couple of fine
points, however...  First, I don't think there needs to be an
"OrderLineItemsWithGraphic" specialist, since there is nothing else that
would talk to it.  It's fine in this case to have the line item classes
(either with graphic or without) handle their own UI snippets.  UI
delegation is for when an object needs to display UI for some *other*
object than itself, since you can always use class extenders and other
techniques to reshape the apparent class of an object retrieved from a
specialist.  The interface which other objects deal with is
"OrderLineItem", and they simply expect a portion of the form to be
rendered, and it's okay for the class to handle that.

I got a bit confused here... the UI snippet for uploading a graphic
actually comes from the Graphics Specialist.

That's fine, but it should be by way of an object that's filling the
OrderLineItem role, yes?

But how can this work? If I ask for the graphic in 
Product.addMeToOrderForm, an OrderLineItem object doesn't exist yet. 
So Product has to ask the OrderLineItems Specialist for the UI 
snippet, and OrderLineItems gets it from the Graphics Specialist. 
Then Product.addMeToOrder can create a new OrderLineItem and hand it 
the form fields for the graphic. Although, to make it cleaner, 
Product would add  OrderLineItems.newLineItemSnippet to the form, and 
OrderLineItems would decide what needs to be included in the form - 
so Product doesn't have to explicitly ask for a Graphic upload form.


  Or I could
eliminate the problem by uploading the graphic from a form displayed
by the order line item after it has been added.

That's actually what I thought you were doing/intending.

This is probably the best way... but it wasn't my original plan. I 
need to ask for a quantity for every added product, so I was going to 
have Product.addMeToOrderForm ask for quantity and for a graphic. But 
instead, I can add a quantity field to the product display page, next 
to the "Add to Order" button. Then addMeToOrderForm isn't needed at 
all, Product.addMeToOrder will create a new OrderLineItem object, 
which will then ask for the graphic if it's needed.


  Here's the question...  how many behaviors are different in the order line
item itself?  Are you also using fulfillment line items?  If the only
difference to the order line item is that it references some additional
data, then I'd say a single class would be fine.  Most of the behavior
probably comes in on the fulfillment line item, yes?  Again, you can ask
your FulfillmentLineItems specialist to create
"newLineItemFor(orderLineItem)" and let it decide what kind of
implementation to hand back.  In this case, it probably will be a different
class, while for the order line items, it may or may not buy you anything.

I haven't thought of using fulfillment line items... not sure what
they are for? An order is considered fulfilled once all items have
been shipped, so order line items are responsible for tracking
everything that happens until a ShipmentLineItem is created. The
order line item for a customizable product tracks the product using
state values like 'sent to factory', 'received from factory', etc. So
it needs a new set of state values, as well as methods like
'sendManufacturingOrderToFactory'.

What exactly does the fulfillment role you're referring to do? Does
it do more than a shipment role?

Fulfillment would be between ordering and shipping, covering such things as
pulling items from the warehouse to customizing them with the graphic.  I
assumed that an order line item was only meaningful until you have a
completed order.  You may not need the complexity, but to me it seems like
a seperate phase with a very different set of behaviors than what I would
think of as an order line item.  If I were doing an app like this, I'd at
least have some sort of state/status objects to delegate these different
behaviors to.  But I'd say this could be left to the taste of the chef.  :)

This is confusing... because in all the E-com designs I've looked at, 
the order state machine covers everything up to 'order fulfilled'... 
you're suggesting stopping the order states at 'order authorized' and 
moving the fulfillment states to the fulfillment object? Also, what 
do you mean when you say 'state/status objects'? I can understand 
having OrderLineItem, FulfillmentLineItem and ShippingLineItem where 
each covers a different range of states, but are you suggesting 
having separate objects just for tracking the state?

I think your talking about something else.  Last i checked, "fuzzy logic"
was a logical algebra based on the existence of intermediate truth states,
between "true" and "false".  It has little or nothing to do with
aproximate searching, though i guess you could use it to make assertions
about the aproximations.  I think what you all are talking about is "fuzzy
matching".

 I.e., it will somewhat intelligently return words that are similar in
 what they mean, using grammar rules (chopping off endings of words and
 making them match others).

There are also matching mechanisms like soundex, that account for
misspelling by translating words to phonetic-equivalent normalized codes,
and comparing on that basis.

Re: [Zope-dev] New UI for 2.3

Steve Alexander wrote:
 
 I think the new UI for 2.3 is great improvement over 2.2.
 
 I'm already finding the sorted tables of folder contents useful, and
 having the add new items select at the top saves time.
 
 However, I do not like the 3-frame interface. I feel that the top frame
 is wasted space. The Zope logo and "Logged in as username | Logout"
 could as easily go at the bottom of the tree-view frame on the left.
 This would leave extra screen space for doing work.
 
 I also much prefer blue to black as a background colour for the tabs and
 the "Root Folder" link. The black seems a bit overbearing.

Hmm. I haven't checked out the new interface myself yet, but
I wonder if DC did any usability testing on their new UI?

Cheers,

 I've been using zope for a couple of months, i have found zope to be a
 great product and thank you for creating it. Currently i have run into a
 problem, i need to access the AUTHENTICATED_USER in a
 standard_error_message called by notFoundError in BaseRequest.

 I was wondering if the authentication routine can be added before the
 authentication routine in BaseRequest? Or if this is not possible it
 could be split into a function and and call it before the notFoundError
 call as well?

 There are many reasons you might want to do this, i have listed some
 below:

 * You want list possible urls the reader could have meant but don't want
 to show let Anonymous users see possible privileged urls

 * You want to provided different error messages for different people,
 i.e. a more advanced error for coders, a simple error for html writer, a
 special error for normal people

 * You wanted errors to only be reported it they where caused by certain
 users

 and the list could go on

The whole threading spiel in Zope works because of ZODB persistence; any
thread accessing an object whose variables have been changed has to retry
with a fresh copy from the ODB.

But because _v_* variables don't get pickled, another thread will never
see them. If you want non-persisting (volatile) variables shared between
threads, you'll have to devise your own mechanism for assuring the
thread-safety of those variables.

 I can't help you fix it but I can tell you what the problem is, the file

 too big for Zope to cope with in one transaction so it starts a

Re: [Zope] xmldocument

2001-01-10 Thread Phil Harris

Bak,

I can't help you fix it but I can tell you what the problem is, the file is
too big for Zope to cope with in one transaction so it starts a
sub-transaction and there is a bug in the sub-transactioning engine.

The same thing happens with a normal 'File' type as well.

You should probably check the collector to see if this has been fixed or
even reported.

[Zope] List of New products

2001-01-10 Thread Francois-regis Chalaoux

It was a great idea to get the list of product sort on date in download zone.
Today appears only categories and product annonced in news.

So, is it a maintenance period or a stable presentation of products ?

to say the file is big is an understatement.  
how can adding a news file be too big for zope to cope?  unless the default 
XML Document is huge. i'll peek at the collector.  thanks phil

[Zope] Re: [Zope-dev] ZCatalog and 'fuzzy logic'

2001-01-10 Thread Morten W. Petersen

 I do not think that "fuzzy logic" is strongly related to "regexp-like".
 Anyway.
 
 Fuzzy searching often means "finding matches with characters omitted,
 replaced or inserted".

It seems I misunderstood the term fuzzy logic myself.  Fuzzy logic means
if I search for a word, for example 'programmer', it will return matches
to the words 'program', 'programming','programmable' etc.

I.e., it will somewhat intelligently return words that are similar in
what they mean, using grammar rules (chopping off endings of words and
making them match others).

Hmm.

Cheers,

Morten

RE: [Zope] Tux Zope?

2001-01-10 Thread Jonathan \(Listserv Account\)

 This is precisely what Zope's new cache management architecture is
 designed to do.  Just create the site then install a cache manager
 object such as an "Accelerated HTTP Cache Manager", available in the
 StandardCacheManagers product.  Visit the "Associate" tab of the cache
 manager to locate all images that should be served by Tux rather than
 Zope.  Turn on the checkboxes.  Voila!

Impressive. The cache management architecture is part of 2.3 right?
Gotta try it sometime this week...

 Accelerated HTTP cache managers set some HTTP headers on the
 response.
 The headers are recognized by downstream caches and the response is
 cached for a determined period.  Simple, reliable, and flexible.

Simple indeed. Good work :)

[Zope] permissions problem upgrading to 2.3.0a1 from 2.1.6

2001-01-10 Thread Jerome Alet

Hi,

I've been using 2.1.6 for a long time without any problem, using a home
compiled python 1.5.2

Yesterday I've tried to upgrade to 2.3.0a1 the following way:

export each and every home made sites and products (ZClasses) from 2.1.6
stop 2.1.6
install 2.3.0a1 and start it
import each and every exported sites and products

(I've not tried using the same Data.fs as 2.1.6)

In all instances of a ZClass I've made, I used to (in 2.1.6) call a DTML
method from my browser which was protected in a way to display the
authentication box, allowing me to enter my username and password.

The username and password should give me a role created in the ZClass
instance constructor, this role is allowed to create and modify some
subobjects (another ZClass)

Since I've installed 2.3.0a1 then when I tell my browser to "call" the
DTML method the authentication box appears but I'm not able to
authenticate myself: it always give me an unauthorized exception.

Looking at zope log it gives me a 401 error on the DTML method.

If I modify this method to do nothing but return plain text the problem
persists. 

I've checked several times the username and password and I'm sure I've
typed them correctly.

In one instance of my ZClass I've tried to give all permissions to the
created role, but with no luck.

I've finally stopped 2.3.0a1 and relaunched the 2.1.6.
 
Does someone have any idea of where the problem may come from ?
Should I try to use the same Data.fs of 2.1.6 ?
Should I try to use 2.2.5 instead of 2.3.0a1 (I'd like to be able to use
PythonScripts) ?

Thanks in advance.

[Zope] Import problem

2001-01-10 Thread Andreas Tille

Hello,

I tried to create my first class following a tutorial.  I exported
the rudimentary class via export function.  Now I wanted to import
it on my laptop to continue working on it but importing failed with
the message:

   The object my_class_name does not support this operation

What could be wrong here?
Which information do you possibly need?
Is there a document to read first before trying such stuff?

Kind regards and sorry for this simple question

[Zope] REPOST: dtml-with doesn't work

2001-01-10 Thread Mayers, Philip J

Hopefully that will get someone's attention. I have an SQL method that
returns

(name,domain,otherstuff)

I have a DTML method (/root/host/show) that looks like this:

dtml-comment

'name' and 'domain' are set to the primary hostname
and domain at this point by whatever calls this
DTML method

POINT A
/dtml-comment

dtml-in "HDB_get_ip_aliases(ip=ip)"
  dtml-commentPOINT B/dtml-comment
  dtml-let name2=name
domain2=domain
dtml-with alias
  dtml-commentPOINT C/dtml-comment
  dtml-with "_.namespace(name=name2,domain=domain2)"
dtml-commentPOINT D/dtml-comment
dtml-var show
  /dtml-with
/dtml-with
  /dtml-let
/dtml-in

The folder structure is:

/root
  /alias
show
  /host
show

At the points marked B and D, dtml-var name and dtml-var domain work
fine, but at point B, name and domain have been reset to what they were at
point A. Why? This is totally broken - I'm *this* far from downloading the
servlet engine and giving up completely. Zope appears to be completely
non-intuitive in many respects, and combined with the generally lamentable
documentation, is taking up more of my time than I'm willing to spend on a
theoretically simple task.

Phil

[Zope] Memory problems

2001-01-10 Thread Tom Deprez

Hi,

Since a few days I'm experiencing some response problems on my zope site. At
some moments calling a page goes very fast a few seconds later, recalling
this page takes very long! At the end, every page takes long time, if they
ever appear

If I use a simple memory checker program, then I see that memory leaks
away (memory goes from 48Mfree to 41M in 15min!! and eventially it ends
at a few thousands K)  However, I've no idea if it is comming from Zope
2.2.5 or from my database adapter in zope, or from somewhere else
Is there a good way to check memory leaks and to pinpoint them?

If I ask to show me the processes on my Linux box, I see the following
related ones :

Is it normal that zope opens so much processes?

That was how I had the code originally. Didn't help. I've already read the
Zope 'book' (if I were using 2.3 (which I can't, because LoginManager
doesn't work OOTB), I'd be using Python methods to do most of this instead.
I'm not, I'm using 2.2.5)

RE: [Zope] SQL Method, dtml-with and namespace weirdness

2001-01-10 Thread Mayers, Philip J

Sorry - I'm being unclear: the result is exactly the same either way i.e.
the variables "name" and "domain" seem to be reset to the values from
outside the dtml-in block when entering the dtml-with block.

I'm wondering if it's a bug in the postgres DA, since I can't reproduce it
with a quick gadfly test. I'm just going to try it out now.

I'm using Zope 2.2.5, PoPy 2.0.1 from SourceForce, and ZPoPyDA-1.1-pre2 - I
couldn't get any (potentially more stable) combination of PoPy or ZPoPyDA to
work.

RE: [Zope] SQL Method, dtml-with and namespace weirdness

2001-01-10 Thread Mayers, Philip J

Ok, using Postgresql 7.0.2-2, PoPo 2.0.1, ZPoPyDA 1.1-pre2, Zope 2.2.5,
here's a reproducible scenario:

Create the following tables in your database:

create table bugtest1 (
name text,
domain text,
);

create table bugtest2 (
name text,
domain text,
refer text,
foreign key(refer) references bugtest1(name)
);

insert into bugtest1 values ('a','aa');
insert into bugtest1 values ('b','bb');
insert into bugtest1 values ('c','cc');
insert into bugtest2 values ('w','ww','a');
insert into bugtest2 values ('x','xx','a');
insert into bugtest2 values ('y','yy','a');
insert into bugtest2 values ('z','zz','a');
insert into bugtest2 values ('g','gg','b');
insert into bugtest2 values ('h','hh','b');
insert into bugtest2 values ('i','hh','b');

Create the following folder structure:

/root
  dbconn (ZPoPyDA connection to whatever database you just put the tables
in)
  index_html
  get_host (Z SQL method)
  get_alias (Z SQL method)
  /alias
show
  /host
show

/root/get_host

select * from bugtest1

/root/get_alias

select * from bugtest2
dtml-sqlgroup where
  dtml-sqltest name column=refer type=string
/dtml-sqlgroup

/root/alias/show

TRTD/TDTDdtml-name;/TDTDdtml-domain;/TD/TR

/root/host/host

TRTDdtml-name;/TDTDdtml-domain;/TD/TR

/root/index_html:

  1: dtml-var standard_html_header
  2: TABLE
  3: dtml-in get_host
  4:   dtml-with hostdtml-var show/dtml-with
  5:   dtml-in "get_alias(name=name)"
  6: dtml-let name2=name
  7:   domain2=domain
  8: dtml-with alias
  9:   TRTDPOINT

 15: /dtml-let
 16:   /dtml-in
 17: /dtml-in
 18: /TABLE
 19: dtml-var standard_html_footer


The output of all that is (a bit hard to read):

a aa 

POINT A a aa 
POINT B w ww 
 a aa 
POINT C w ww 
POINT D w ww 

POINT A a aa 
POINT B x xx 
 a aa 
POINT C x xx 
POINT D x xx 

POINT A a aa 
POINT B y yy 
 a aa 
POINT C y yy 
POINT D y yy 

POINT A a aa 
POINT B z zz 
 a aa 
POINT C z zz 
POINT D z zz 

snipped for clarity


So: at point A, the "name" and "domain" variables have been overwritten with
the "name" and "domain" variables as they were on line 6/7, *BUT* name2 and
domain2 haven't been overwritten (point B). BUT, outside the dtml-with tab
(point C) "name" and "domain" are at their correct values.

So - given that the dtml-with tag "must" work, I'm clearly not understanding
*how* it works.

Phil

[Zope] MySQLDA and MySQL-python - patch needed?

2001-01-10 Thread paul_s_johnson

My Zope-MySQL connection is still not quite working. It appears that the
request from Zope is reaching MySQL and it if is an UPDATE or INSERT query
it executes properly on the MySQL side. However, SELECT queries and similar
are not getting their information back to Zope from MySQL. Is there some
patch I am missing here? Anybody know how to fix this?

FYI:
I installed from these rpms

ftp://ftp.logicetc.com/pub/Zope/RPMS/MySQL-python-0.2.1-1.i386.rpm
ftp://ftp.logicetc.com/pub/Zope/RPMS/Zope-ZMySQLDA-1.2.0-1.i386.rpm

This did not install into my Zope installation directory, so I used a
symbolic link in my Zope Products directory that points to the directory of
MySQLDA install. Could this be the cause? Perhaps information that should
be returned from MySQL is getting lost on the return trip. If so, how would
I fix it? Any ideas?

Has anyone else had trouble using the ZWikiWeb product?  As Manager, there
are no problems, but users I have added cannot add ZWikiWebs in their own
folders.  While already logged in, a login box comes up, meaning they do not
have the necessary permissions.  When I cancel the box, I get the Zope error
message stating that the user is not authorized to access Control_Panel.  I
have given the user role (that I created) access to view contents, view, use
factories, change zwiki pages, and serveral others.  Is there something I am
missing?

[Zope] Design/DTML question

2001-01-10 Thread Timothy Wilson

Hi everyone,

I'm working on a Web page for our local school board. I'd like to create a
table that would display links to past board meeting minutes. The table
would look like this: (Note: dates are bogus)

+---+
| Meeting Minutes   |
|   |
| Monday, Jan. 10  Monday, Mar. 7   |
| Tuesday, Jan. 24 Monday, Mar. 20  |
| Monday, Feb. 7   Monday, Apr. 5   |
| Monday, Feb. 27  Tues., Apr. 19   |
|   |
|1999 | 2000 | 2001 |
+---+

By default, dates for the current year would be displayed, but clicking on
the years at the bottom of the table would display those dates.

Right now, I've got the dates stored in a TinyTable. I can iterate through
that list and generate the links, but I can't figure out how to display the
table in two columns.

dtml-in meetingDateTable
 trtddtml-var meeting_date/td/tr
/dtml-in

will print the dates in a single column, but how can I iterate through and
refer to two different dates in one dtml-in pass? (Does that make sense?)

The second thing I'm tring to figure out is how to make the year links at
the bottom generate the new table of dates from a different TinyTable. Maybe
I should use the same TinyTable for all of the meeting dates and pull out
whichever year I need when the table is rendered.

I'm also wondering if I should implement these meeting minutes and agendas
in a ZClass. At first it seemed like this would be too simple to bother
with, but now I'm wondering if a ZClass would be a better approach. I'd
appreciate any comments.

You could access it through dtml from 1-2 as dtml-with

 too big for Zope to cope with in one transaction so it starts a

 The same thing happens with a normal 'File' type as well.

 You should probably check the collector to see if this has been fixed or

[Zope] Proximity searches w/ ZCatalog

2001-01-10 Thread sean . upton

Supposedly proximity searches are possible... like "FIDELITY within 8 words
of MUTUAL FUNDS."  Can't find anything in docs.  Anybody have a suggestion
here...

Thanks,
Sean

Re: [Zope] Proximity searches w/ ZCatalog

Really using ZCatalog? I've never heard of that. There some globbing
searches *? etc, but nothing like that is readily apparent from the API.
Sounds like an interesting (ie complicated) idea...

 Please dont post in CAPS, you are more likely not to get a response.

 Heres one idea, the versioning comes from cookies. What error do you get
on
 the Undo? Have you tried to Undo everything after the deletion of the
 version?

 Make yourself a cookie for your browser matching the offending version.
Its
 simply of the format:

 NameZope-Version
 ValueUrl to version object, eg: /testing, /foo/testing.

 You are then in the version, and should be able to Undo.

Yeah, I think you'd put "FIDELITY ... MUTUAL FUNDS" in the search box.

I think Dieter Maurer [EMAIL PROTECTED] wrote the code, so he's

Re: [Zope] Storing and Using Object references

2001-01-10 Thread Andy McKay

In python its even easier, and depends what you are doing.
Basically you want to get a handle to another object so you can do something
along the lines of

obj = self.container1.containter1a.item1
result = obj.mymethod()

there are many funky variations on that of course. There's also interfaces
such as REQUEST.resolve_url, _getOb, getItem that you may want to look into.

[Zope] raw search on a ZClass

2001-01-10 Thread aZaZel

Hi!

I have some ZClass istances that are catalog-aware.
Someone knows how to do raw (full text) searches over all the property 
values of the istances? I have tried the "raw" index trick used for 
other object types but without success. Or maybe another way to do the 
thing .

Thanks in advance

Re: [Zope] ZWikiWebs Product

2001-01-10 Thread Marty Stitt



I have a 2.2.5 based system with the Yihaw and ZWikiWeb products installed.

When I try to add a ZWikiWeb within a Yihaw folder, I experienced a
permissions problem that sounds like what you describe.  But, I did find that
I could install a wiki object within a standard Folder object without this
problem.  So, when you say that users can't install them in "their own
folders", what type of folder is that?  Instead of trying to debug why a
wikiweb object couldn't be put into a Yihaw Folder, I just reworked my design
to let me put my wiki objects into a standard folder, and then created a
linkage so that the users involved could get at the wiki.

Within the Security tab of the management page for the wiki object, there are
two permissions you want to assign to some role your users have:  "Add ZWiki
Pages", and "Change ZWiki Pages".





Matthew Monacelli wrote:
 
 Has anyone else had trouble using the ZWikiWeb product?  As Manager, there
 are no problems, but users I have added cannot add ZWikiWebs in their own
 folders.  While already logged in, a login box comes up, meaning they do not
 have the necessary permissions.  When I cancel the box, I get the Zope error
 message stating that the user is not authorized to access Control_Panel.  I
 have given the user role (that I created) access to view contents, view, use
 factories, change zwiki pages, and serveral others.  Is there something I am
 missing?
 
 Thanks,
 Matt

   ... isolating privacy checks ...
   dtml-var privacy
   dtml-var standard_html_header
   dtml-var standard_html_footer
   /dtml-if

 I know about 2 possible approaches:

  I. let your "privacy" method return a value (using "dtml-return")
 and check it above:

 dtml-if privacy
   ...header...
   ...
   ...footer...
 /dtml-if


I've gone for a 'method' based on this first idea of yours.  Here is what
appears in each zclass instance.

dtml-call privacy
dtml-if "available == 1"
dtml-call "RESPONSE.redirect(restricted+'/restricted.html')"
dtml-else
dtml-var standard_html_header

dtml-var standard_html_footer
/dtml-if

And here is the privacy method.

dtml-call "REQUEST.set('available', 0)"
dtml-if "propertyLabel(availability) == 'private'"
dtml-call "REQUEST.set('available', 1)"
/dtml-if

dtml-call "REQUEST.set('dom', _.string.split(REQUEST.REMOTE_ADDR, '.'))"
dtml-if "dom[0] == '192'"
dtml-if "dom[1] == '168'"
dtml-call "REQUEST.set('available', 0)"
/dtml-if
/dtml-if

dtml-in PARENTS
dtml-let PARENT="_.getitem('sequence-item')"
dtml-if "PARENT.hasProperty('dehs_site_root_folder')"dtml-call
"REQUEST.set('restricted', PARENT.absolute_url())"/dtml-if
/dtml-let
/dtml-in


It's not perfect (that would be when there is nothing for the user to break
in each instance), but it's better than it was and also allows me to edit
only one privacy method to change the access rights.


  II. I think (this implies, I am not sure), that ZPublisher
  translates exceptions into HTTP response codes.
  This would mean, you could try:

In your "privacy" method:
   
   dtml-call "RESPONSE.redirect(...)"
   dtml-raise type="Redirect"/dtml-raise
   

in your other objects:

   dtml-call privacy
   ...header...
   
   ...footer...


You've lost me a bit there.  Where am I actually checking to see if the user
has access rights?

Cheers

[Zope] reindex when a zclass is edited

2001-01-10 Thread Tim Hicks

I know this has been asked numerous times before (once by me!), and I'm
sorry to cover the same ground again, but I've spent all afternoon searching
through the list archives to no avail. I have a zclass that is catalogaware
(selected first and all that).  When I add an instance, it gets cataloged
and all is fine.  I followed the how to
(http://www.zope.org/Members/AlexR/CatalogAware) and successfully made my
instance get reindexed when the properties are changed, but I can't for the
life of me figure out or find anywhere that can tell me how to make the
instance get reindexed when it is edited.  I'm assuming that it is similar
to the process for reindexing when the properties are changed, but I'm just
not sure of the details. If it's not too much trouble, could someone give me
detailed instructions (or a link) on how to do this. I'd really appreciate
it.

In your method which is called by your edit form, insert a dtml-call
"this().reindex_object()" after updating the properties.

Off the top of my head -

you don't mention whether they have Add ZWiki Webs permission -
presumably they do

are you using the zwikiwebs.zexp shipped with zwiki ? The separate

 these are python classes.
 
 Example: object 1 is :  /container1/container1a/item1  object 2 is :
 /container2/container2a/item1  object1 needs to hold a reference to
 object2.  I'm really stuck on how to store and access object2 from

 any pointers?

I think what you're looking for is getPhysicalPath() and
unrestrictedTraverse().  Store object2.getPhysicalPath(), which returns
a tuple, in object1.  To find object2 again, call
object1.unrestrictedTraverse(stored_physical_path).

Note that this only works in Zope 2.2.x+.

Re: [Zope] slow DocumentTemplate (dtml) import speed

Check whether your Web Server supports FCGI.

If the Web Server is Apache, then there are several Apache
modules to integrate Python inside Apache.
I think Guido van Rossum uses "mod_snake".
Search "comp.lang.python" via "www.python.org" or "dejanews".

All these approaches would save you the new process spawn

If you cannot use any of these options, then the

You can use the program "top" to analyse memory usage.
This will show you, which process[es] consume memory.

If Zope does it, then you can use "Control Panel-Debugging"

There was a big shift in security policy during

Many Python based products need to be changed in order

[Zope] Deleting a Role Doesn't Appear to Remove Permissions

2001-01-10 Thread Jason Grigsby

Today I ran into an issue in Zope where even after you delete a role that
the permissions associated with that role exist. If a user has that role
assigned to them, whatever permissions where last assigned to that role will
be available.

To test this, I created a test file with the following code:

dtml-if "AUTHENTICATED_USER.has_permission('Set Access Rule',content)"
foo
/dtml-if

I chose Set Access Rule as a permission that is not normally associated with
a regular user. Testing this page produced no foo because the user does not
have access to the "Set Access Rule" permission on the content object (you
could pick any Zope Object to test on).

Then I created a test role. I assigned that test role to a user. I again
tested the output and got nothing.

I then gave the test role the permission to "Set Access Rule". Now when the
page is reloaded, foo appears.

Here is where it gets interesting. After deleting the test role, foo still
appears. This means that the role, while supposedly deleted, still exists
and is still assigning permissions.

Finally, I create a new role with the same name as the test role I created
earlier. This new role had the "Set Access Rule" button already
selected--indicating in my mind that the role was never really deleted.

If I am correct about this, this means that if we create a role and then
delete it, we will need to make sure that the role does not exist for any
users or they will continue to have the access that they had before.

Has anyone else run into this or seen a reported bug similar? (I searched
the Zope Bug Collector to no avail).

A script to put in lib/python, supplying your own user_role_name and
user_list:

user_list = ??
user_role_name = ??

import Zope
app = Zope.app()
folder = app.acl_users
for u in user_list:
  folder._doAddUser(u.name, u.password, (user_role_name,), ())
get_transaction().commit()

See how that works?  Those first two lines give you the actual
database--not just a special view of it but a live connection.  From
there, you don't use some funny mechanism to get acl_users--it's
actually a simple attribute of the root object.  Then you modify
acl_users however you want and commit the transaction.  If any error
occurs, the transaction will be aborted and changes made to the database
will be forgotten.

Beautiful, isn't it?

Are you sure, it was '[1,' '2,' '3]' and not ['1', '2', '3', '4']?

If it were, it would be really strange, unbelievable.

['1', '2', '3', '4'] would be normal, when you use
a list (it definitely is one!) in e.g.:

  dtml-var "_.getitem('toks')"

as a list (of cause) can not be part of a generated HTML page.
It must be converted into a string. And the above
it the string representation of a list.

To get the representation, you seem to favour (though
I do not understand why), you could use:

  dtml-var "_.str(_.getitem('toks'))[1:-1]"

This make the string conversion explicitly ("_.str")
and then keeps the slice "[1:-1]" which means
everything beside the first and last character,
i.e. you chop the '[]'.

Re: [Zope] REPOST: dtml-with doesn't work

2001-01-10 Thread Dieter Maurer

Usually, I complain that problem reports are too terse.
But, your's was very big, such that I did not read it
carefully. It is very difficult to get it right for everyone.

Just a remark:

  SQL methods do *NOT* look at the DTML namespace *AT ALL*,
  just at REQUEST (or the expliciitly passed keyword arguments).

  Thus, "dtml-with", "dtml-let" and friends are all ineffective
  with respect to ZSQL methods.

May be, that explains your problem.
May be not, as I am not sure, that you need the values indeed
inside a ZSQL method.

I can assure you: "dtml-with" does work.

  I think Dieter Maurer [EMAIL PROTECTED] wrote the code, so he's

No, I just looked for bugs in it and found several.

It is almost as you described:

  the proximity operator is "..."

  you can not control the distance

  "..." is effectively an "and" with a high score when the
terms are near together and a lower score for higher
distances

  term in "..." are effectively combined with "...",
thus: '"bear wine champagner"' is equivalent to
'bear ... wine ... champagner'


ZCatalog would interpret "FIDELITY ... MUTUAL FUNDS"
as "(FIDELITY ... MUTUAL) or FUNDS"
The nearest result what "sean" asked for, would
probably be 'FIDELITY ... "MUTUAL FUNDS"',
which is equivalent to 'FIDELITY ... (MUTUAL ... FUNDS)'.

I have not too much confidence in ZCatalog (yet ; this
may change now that Chris P is responsible for it).
I doubt, it will implement "A ... B ... C"
sensefully.
It is a big question, all together, whether a binary
operator is the correct choice for proximity.

 Subject: [Zope] MySQLDA and MySQL-python - patch needed?


 My Zope-MySQL connection is still not quite working. It appears that the
 request from Zope is reaching MySQL and it if is an UPDATE or INSERT query
 it executes properly on the MySQL side. However, SELECT queries
 and similar
 are not getting their information back to Zope from MySQL. Is there some
 patch I am missing here? Anybody know how to fix this?

 FYI:
 I installed from these rpms

 ftp://ftp.logicetc.com/pub/Zope/RPMS/MySQL-python-0.2.1-1.i386.rpm
 ftp://ftp.logicetc.com/pub/Zope/RPMS/Zope-ZMySQLDA-1.2.0-1.i386.rpm

 This did not install into my Zope installation directory, so I used a
 symbolic link in my Zope Products directory that points to the
 directory of
 MySQLDA install. Could this be the cause? Perhaps information that should
 be returned from MySQL is getting lost on the return trip. If so,
 how would
 I fix it? Any ideas?

The RPMS install the DA where the Zope RPMS install Products.  I actually
put my products in the same place (RPMS or not) and use symbolic links for
the different instances of Zope I have running, so I know symbolic links
will work.  If DA product is showing not broken in the Control Panel, then
it was installed properly.

Are you getting any error messages?  How do you know the information is not
getting back to Zope?  When you test the queries on the connection
management screen, do you get results?
