The domain expert tells me that he want to keep particular information about Suppliers: what they supply, and their address details. However, he also wants to store the address details of any other contacts he wishes. He'll sometimes need to search through all of the contacts and suppliers (and in future, anyone that has an address) by phone number or name or address. The domain expert calls the thing that allows him to do the searching (and also browsing) of addresses his "address book", and it reflects a real paper-based artifact. I'm sure I could rename it "Contacts" or "Addresses" without causing too much confusion, though. From the way I just described it, there is no requirement for the addresses to be stored all in one place. There is a requirement that you can search and browse through all addresses, and return the appropriate object. So, I guess a good way to go is to add an "address" propertysheet to Contact and Supplier, and have triggers that add the address details of both to an Address catalogue. Bunch of questions: Is this the ZPatterns ideomatic way to do this? Dunno. Explain the problem you're trying to solve, and I'll tell you the simplest way I know to do it. Aha... the missing link :-) What kind of propertysheet should I be using? Depends on what your application needs. I can see circumstances where the best place for that sheet could be LDAP, SQL, or the ZODB. I wasn't being very clear there. What kind of propertysheet should I be adding to my DataSkin-derived ZClasses? There are two kinds: "Common instance" and "DataSkin attribute". It looks to me like at present the "DataSkin attribute" flavour will work better with SkinScript. In which case, I think your confusion comes from terminology. I would expect to store "Contacts" or "Entries" in an addressbook, and these would have address sheets, as would "Suppliers" or whatever else. That makes sense. Suppliers are sored in the Suppliers specialist, and general Contacts are stored in the Contacts specialist. The contacts specialist provides searching appropriate to the domain of addresses and contacts. Anyway, to answer your question - I think that your getItem() for an address specialist wants to return some object with an address sheet. But not an address object. Contact, Entry, Supplier, TennisBuddy... whatever the heck kind of object it is. This is starting to make much more sense.

[Zope-dev] RE: Additional Quoting; Exposing Auxiliary Tag Functions via _
Dieter Maurer writes: The existing "quote features" name the context for which quoting is needed. The context determines what needs to be quoted and how quoting has to be done. Your proposal does not state the context but only the how. Otherwise, I would think such an extension would be good. You are right here. I just came up with "slash_quote" off the top of my head. "string_quote" is a good language-neutral name I think that is similar in spirit to the present format options. Thus, I propose: 1. new quoting directive "string_quote" quoting Python strings i.e. ", ' and \ are quoted. This would work for Javascript (and other languages with C-like quotation and string literals), too. 2. all auxiliary functions for DTML tags, especially quoting, should be available via the namespace. To avaid namespace pollution, they may go into a separate module, say 'aux'. E.g. I would like to use quoting, formatting etc. inside DTML embedded Python expressions in a form like that: dtml-var "... _.aux.fmt(x,'%m/%d/%Y')..." and dtml-var " _.aux.sql_quote(x)..." This idea has merit, and extends the usefulness of these options to parts of an expression rather than just the whole thing. I think calling the module 'aux' might not be the best for code readability sake though. Perhaps it should just be called fmt or format. Perhaps like so: dtml-var "... _.fmt.expr(x, '%.2f') ..." and dtml-var "... _.fmt.string_quote(x) ..." newbie format methods could be added too (Feature creep alert!) like: dtml-var "... _.fmt.currency(x) ..." in place of the first one. ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

[Zope-dev] Are full pathnames in error messages a security bug?
I don't know if this has been raised before, but the following excerpt
from the most recent SANS security alert concensus made me think:
-- Forwarded message --
[...]
-- {00.31.014} Apache TomCat leaks system information
Apache's TomCat server has been found to provide various types of system
information to an attacker-such as full system paths being displayed in
error messages. TomCat also comes with the "snoop" servlet, which
provides even more detailed information about the system when invoked.
Obviously the 'snoop' servlet is the reason this was posted, but
still, they are calling full path information a security leak.
Not perhaps something to put high on a priority list, but should there
be a way to prevent full path information from appearing in
error messages? It would have the side benefit of making the
error messages more readable grin.

[Zope-dev] Re: Collector #1457: DateTime strftime() -- still broken

Steve Alexander reported:
This is a patch to address collector item 1455.
Here's a working patch to make formatting of a DateTime instance work as generally
expected, when you use

or whatever.
It could be made more efficient by compiling the two regular expressions into
class attributes. However, a bug in ts_regex stops it using compiled regular
expressions in gsub.
See the following URL for a description of the regex bug.

def Date(self):
Thanks for the report. Per popular demand based on list
feedback, strftime() now formats using the current timezone
representation of the DateTime object (consistent with all
of the other DT formatting methods).
For those who really needed it to format based on GMT, you
can use the toZone() method to get a copy of the DateTime
object represented in GMT and call the formatting methods
on that object:
dtml-var "myDate.toZone('GMT')" fmt="%y, %m, %d"
or
dtml-var "myDate.toZone('GMT').strftime('%y, %m, %d')"
-Brian
I just looked at the fix in CVS. I'm sad to report that it is still
broken.
Here's the patched method from CVS:
def strftime(self, format):
# Format the date/time using the *current timezone
representation*.
jfirst = _julianday(self._year, 1, 1) - 1
jtoday = _julianday(self._year, self._month, self._day)
julian = jtoday - jfirst
time_info=(self._year, self._month, self._day,
self._hour, self._minute, self._nearsec,
(self._dayoffset + 6) % 7,
julian,
0)
return strftime(format, time_info)
This gets time.strftime to format the time in the DateTime instance,
shifted by an appropriate amount. However, if you try and format with %z
or %Z to display the timezone information, it always comes out as GMT.
So, the implementation has gone from correct but not useful, to
generally useful but technically incorrect.
To see the problem, apply the patch and try this DTML snippet:
dtml-let time1="_.DateTime('2000/07/23 14:03 BST')"
Time: dtml-var time1 fmt="%B %d, %Y %H:%M %Z" br
Time: dtml-var "time1.fCommonZ()" br
/dtml-let
This prints out the following:
Time: July 23, 2000 14:03 GMT
Time: July 23, 2000 2:03 pm GMT+1
They are being presented as different times.
The first one should read "Time: July 23, 2000 14:03 GMT+1".
A solution is to replace the %Z and %z format substrings with correctly
calculated values, as in my original patch, included towards the start
of this message.

Re: [Zope-dev] Acquisition Confusion :S
I still don't get this :(
Here's the situation:
A has attributes B and C, C has attribute D
my old working:
A.B.C.D = (B o A) : .C.D
now, since C is found in A:
= ((C o A) o (B o A)) : .D
again since D is found in C:
= ((D o C) o ((C o A) o (B o A)))
However, this:
This last line should be (((D o C) o (C o A)) o ((C o A) o (B o A))), which
Implies that rather than the rule I was working on which was:
If X is found in Y, the next line becomes ((X o Y) o {the last line})
This rule applies:
If X is found in Y, then the next line becomes (((X o Y) o (wrapper of
which Y was either parent or self)) o {the last line})
Is this the case?
If so, why? ;-)
In this case aq_inner is the entire
expression, since aq_self is not a wrapper.
I still don't get this at all :(
I hoep someone can help more :~(
The IPC8 slides are in error, and need to be fixed.
Similarly, does the dev-wiki still have a purpose? It feels like the
unmaintained precursor to dev.zope.org...

[Zope] RE: What is the best method to enter more attributes about DTL Document?
Hi Marcin, you can write a new HTML page which add a new document. This page must contains a form which post the datas to the method "AddDTMLDocument", responsible for the creation of this object. But, if you need for example, to associate new properties to the new Document, you have to rewrite also the method "AddDTMLDocument". The destination of your form is now "AddMyDoc" and this new method must contains a line similar to : dtml-call "manage_AddDTMLDocument(...)"

[Zope] FSSession - don't call FSSession twice!
I've been using the excellent FSSession product (many thanks Mr Christoforou) to hold some information on the language a user wishes to display a page in. I kept having weird errors however - every now and again I'd change some code somewhere completely unrelated (even just adding a user) and FSSession would break. Undoing the last change wouldn't help. The error was to do with _v_data and (I think) _v_id or something similar. This post isn't about that problem. From reading through the extremely useful nipltd archives it appeared the problem was not doing a dtml-call FSSession at the beginning of the code. This was bemusing because that code was sitting in my standard header and called everywhere. However, I had an uneasy workaround which did a 'try' on using FSSession and if it failed initialise it in the normal way. I say 'uneasy' because I didn't know why I needed it and when I added another bit of code to handle another cookie that needed to be recorded it broke again. This post isn't about that problem either. I decided enough was enough today and thought I'd try and find out what was happening. So I could give some proper information to Pavlos Christoforou I downloaded the latest version of FSSession and tried to reproduce my error. Bang - I got a much more impressive error. Whenever I went to any of my pages that used FSSession I got the following. Zope has encountered an error while publishing this resource. Error Type: OSError Error Value: [Errno 2] No such file or directory Followed by the following traceback Traceback (innermost last): File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/local/zope/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: ElementWithAttributes) File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 175, in publish File /usr/local/zope/lib/python/Zope/__init__.py, line 235, in commit File /usr/local/zope/lib/python/ZODB/Transaction.py, line 296, in commit File /usr/local/zope/lib/python/Shared/DC/ZRDB/TM.py, line 122, in tpc_finish (Object: TM) File /usr/local/zope/lib/python/Products/FSSession/FSSession.py, line 84, in _finish (Object: TM) File /usr/local/zope/lib/python/Products/FSSession/FSSession.py, line 193, in final_commit (Object: FSSession) OSError: (see above) Interestingly the line above 193 in FSSession.py is a comment which reads 'should never fail'. Well it does and the reason is (as you may have guessed from the title) that I called FSSession twice. Line 193 appears to rename a .tmp file and I'd guess that by calling it twice my second attempt fails as the file has already been renamed. Obviously this isn't the way I should be doing things and I'm going to have a go and see if the new version of FSSession cures my earlier problems. The reason I mention this now is that the problem causes any future attempts at transactions to give the following error - which can only be remedied by restarting zope. Error Type: TransactionError Error Value: A serious error, which was probably a system error, occurred in a previous database transaction. This application may be in an invalid state and must be restarted before database updates can be allowed. Beware though that if the error was due to a serious system problem, such as a disk full condition, then the application may not come up until you deal with the system problem. See your application log for information on the error that lead to this problem. So if you make the same mistake as I did on a production server you will not be popular :-). I'm running this on Zope 2.2.0 by the way (although it happens on the previous production version as well).

RE: [Zope] Re: Unique id product
A different approach: For each entry I just use the current date/time including a call: time.sleep(0.001) This way I am sure each entry will have a unique id. It is only slightly slower (0.001 second for each calc). However, it requires serial processing of entries and a stable time (only server-side processing). Therefore very usable for processing batch-entries as I do.

The variable "self" is the one passed to the constructor method of a particular Python class, and represents the folder you want to put the new object into. I'm assuming the object is a "FooBar Item". The "foobar-%06d" bit generates a unique id for the object that looks like "foobar-290172837", based on the current time. id = int(DateTime().timeTime()) while hasattr(self, str(id)): id = id +1 id = 'foobar-%09d' % id The advantage of this approach is that there is very little contention in most cases.

[Zope] Problem displaying Informix INTERVALs using DTML
Hi, I am using Zope on a PC running on NT and using ODBC to connect to a Informix database. I am running a query that returns a column of INTERVAL type, calculated by subtracting to DATE types. The query, when tested using the test tab, displays the results as I expected. However, when I try to display the results using either a search interface, or my own DTML method, NETSCAPE 4.7 refuses to display the results. Instead it reckons it cannot handle the resultant HTML from the DTML used to produce the results page. Instead, it decides the best thing to do is save the file but when it is reloaded it load just fine. IE5 does get a little further and it will display the page but there are numerous strange characters at the end of the expected interval field. This seems like some additional characters are coming back from the query and they may cause Netscape to trip up and IE5 to display odd characters. What I have tried to do, without sucess, is to get access to the DTML, within Zope, which produces the results of a test on an SQL query. This is where the solution lives!, but I plain just can't find it. I have tried formating the the INTERVAL type and truncating but nothing yields the same results as the 'test' DTML. Any ideas for a poor Zope newbie.

[Zope] ZOracle LOB Questions
Hello!
i have Oracle 8.1.6 ZOracleDA 2.2 installed with Zope 2.1.6 on a red hat
linux machine.
i have an oracle table with one column containing blobs. Now i have
the following problems:
1. How can i retrieve data from that table in zope or in python (syntax) ?
2. How can i insert data to that table ?
i need the zope syntax something like:
insert into blob_table values ('dtml-var image') ???
or the python syntax
i have written a little script:
import DCOracle, sys, os, DCOracle.dbi
dbc = DCOracle.Connect('mozdb_dba/mozdb_dba')
cur = dbc.cursor()
fn = open('test_img.jpg','rb')
data = fn.read()
fn.close()
param = DCOracle.dbi.dbiRaw(data)
cur.execute('select blobcol from blobtable')
dat = cur.fetchone()
cur.close()
dbc.close()
print dat
when i try to execute it i get the following error:
Traceback (innermost last):
File "blobtest.py", line 12, in ?
dat = cur.fetchone()
File "DCOracle/ociCurs.py", line 339, in fetchone
self._error()
File "DCOracle/ociCurs.py", line 109, in _error
raise error, (rc, oci_.OracleErrorMessage(self._c.lda, rc))
oci.error: (24813, 'ORA-24813: cannot send or receive an unsupported
LOB\012')
3. Is there a way to call a stored procedure or function that actually
return values ?
i succeeded in retrieving one particular value out of a table but when
i try a function like :
select * from some_table
i fail...
4. Changes.txt:
Z Oracle DA Releases
2.2.0
Added a small feature that allows you to access LOBs in the Oracle
database. To do this, you must have your maximum number of
results set to '1'. Otherwise, it won't work.
i don't know what this is referring to. where should i make this change?
Ciao,
Alex

Re: [Zope] Limiting folder space
Brendon Grunewald wrote:
I want to use Zope to offer registered visitors to my site a little free
webspace on the site. Since I use hosting service that restricts and charges
me for space, I would like to restrict the size that their zope folders can
consume.
Hence:
Is there any simple way of limiting the amount of space that a folder is
allowed to consume including its subfolders? Alternatively, is there anyway
of checking how much space a folder with subfolders consumes?
I set something up like this for myself at imeme.net (minus the file
limits) its basically just a simple zodb based remote file storage for
friends. basically to do it you can't let your visitors have access to
your manage screens.
example implementation.
create a folder called filesystem
stick all your adding and managing methods in filesystem
add a size limit property to filesystem
for each user create a folder under filesystem.
that folder should probably have a property called current_size
basically you're going to have forms for people uploading a file. on the
page where you would do the manage_addFile stuff you're going to
implement the logic. check size of the file with _.len(file) on the form
submit page and add to current_size see if its above the limit. if it is
don't add tell the user why. if it isn't add it update the current_size
on the directory. voila.
here's some sample code which does the basics of getting file info
without the management logic to get you started. it pretty prints a
table of file info.
table align="center" border="1"
trth colspan="4"dtml-var id Directory Contents/th/tr

Re: [Zope] Starting Zope
Bill wrote... Of course, it is entirely possible the user meant something other than s/he wrote. ;) But that last one doesn't seem to indicate that. To put it succinctly: If you want Zope to bind to port 80 on *nix you have few options: o Change Zope to run SID ** Bad Idea o Modify the kernel so _anyone_ can bind to ports under 1024 ** even worse o START Zope as root, run it as a non-priviledged user, preferably one without a login. You could also run zope behind Apache. The Apache bits that handle root permissions seem pretty well accepted. This doesn't really run Zope listening to port 80, but if you go to port 80 on the machine running Apache, you get to zope. One advantage is that you can bounce Zope all day long without even touching root. Plus depending on your setup you can have Apache running on a separate machine. This can be better depending on the situation (i.e. development machines behind a firewall with private addresses. The downside is that you need to become aquainted with the wonderful worlds of mod-rewrite and site-access[1]. Plus you may take a performance hit. -- cary [1] Can someone explain (or point me to the reason) why the base tag is necessary? It sure can make life difficult!

Re: [Zope] Starting Zope
Interesting argument. However, consider this: if you completely trust your 'firewalled' box, then why not run the web server as root? One response, Protection of the system from simple mistakes by trusted users? Also root can do a lot more, such as putting interfaces into promiscious mode. So the idea is to just lift the bind-to-low-ports check. in your case is the fact that you mention your trust on users(humans are the most easy to compromise, however that argument is a bit OT). However, do you trust all of your webserver code? Do you trust your cgi-bin scripts and applications? And by trust I not only mean harmful intent by the authors of software, but unintentional bugs which can be exploited, and will be given the privilege to bind to 1024 ports even when they run as a user with least privileges. My revised thinking is that the patch should only lift the restriction for just the necessary ports. Another idea is to do it with groups, say let group n be a "net-privileged" group. -- cary Just my opinion. nitesh. On Sun, 30 Jul 2000, Cary O'Brien wrote: Cary O'Brien wrote: Well... If you are running on Linux you could simply edit the kernel code to elimitate the check on being root to bind to low ports. That's what we did. Which is an even worse idea. Why? On a sufficiently firewalled off box, where the few logins are completly trusted, what's the diff? If you were worried about people cracking a user account and getting underneath telnet, than limit the lifting of the restriction to port 80. If you are concerned that non-root users could launch attacks from low ports at other machines, assuming that only good guys can come from low ports is pretty naive. The whole business about not letting anyone but root bind to low ports makes sense for a public access machine where all the first year engineering students have an account, but for a dedicated application server it is kind of misdirected. You ought to be running next to nothing but the application, and you had better trust everyone that you give a login to, and you out to have the thing locked down/firewalled well. So the tiny bit of possible protection may not be worth the hassle/risks of writing your own suid-wrapper, or the complexity of having a redirect and messing with site-access so that the port numbers in the zope -- what it is that parameter -- base or whatever, comes out write.

[Zope] boolean property bug
Probably I found a bug in handling boolean properties in Zope 2.2.0. I can only set them "on", and then can't turn "off". I can have default value "off" (in ZClass definition), but after first switch to "true", it can't be changed. It only refers to handling properties via Zope's management screens.

One thing I considered doing was using 2.2's mountable databases for something like this. Give each user their own database (possibly without undo information) and use a cron job to check file sizes.

what's wrong? Do you know where i can found information about zope erorrs,

Well, unfortunately there is no one place you can go to to find
out about zope errors. In fact, I'm not sure I've seen the zope
error machinery documented anywhere (and documenting it involves
discussing exactly how the dtml interpretation machinery works, which
would be a good document all by itself grin).
I can tell you what is happening in this case, I think. You will note
that in the part of the traceback I quoted above the last Object listed
is your line that takes slices out of ns_entrydate ([n:m] is called
a 'slice' in Python jargon). The error received is a 'getslice' error.
So it looks like the zope machinery got an error when it tried to
take a slice of ns_entrydate.
Since Python is an OO language and operators can be defined for any
object (well, more or less), whatever type ns_entrydate is *could*
have defined a slice operator. It appears, however, that whatever type
it is, it does *not* define one, since __getslice__ is being flagged
as a non-existent attribute, and that is the attribute that the
object's class would have to define, as a function, in order to
implement the slice operator.
From your code it appears you believe ns_entrydate is a string. Is
it possible that it is instead some sort of datetime object? If
so, then you'd have to call a function on it that returns the string
you want to parse, and call the slice operators on the returned
string. But if it is a DateTime object, you can probably just call
functions to get exactly the strings you want without having
to slice anyway.
I hope this helps.

Re: [Zope] How to start developing in zope
Date: Thu, 27 Jul 2000 06:42:39 -0400 (EDT) From: Firestar [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: [Zope] How to start developing in zope Hi, I have read through(and tried out) the tutorials and Guides at Zope.org, and now eager to port my company's website over to Zope. (The website was originally programmed in PHP) In my original design, I used OOP mainly. I defined each section(e.g. News, Events, Products) as a class by itself, inheriting from a "main" superclass. Each class would contain their own set of attributes(such as font-color, title) and methods(e.g. display news headline, or display events schedule). Common attributes method that are widely used are placed(shared) in the "main" class(e.g. talking to MySQL database). So, if there's any changes or updates, inheritance will propagate the changes to the rest of the subclasses. (As usual, management will require extra features such as personalised page, membership or web-based email to be added in future. Hopefully, this kind of structure would make adding new features a breeze.) I believe Zope is based on a similar way (and much more powerful). I was wondering how shld i start something like this in Zope - i read abt ZClasses(where you can define your own Folders), Products(for defining yr business logic) and DTML(for dynamic data display). Your opinions will be much appreciated. regards, firestar also, use properties which can be used as global variables... by the way, zclasses are a very good way using object-oriented tasks cheers, nico ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

Any objects that you want to be automatically updated in the Catalog must have CatalogAware as one of their base classes.

(I fail to understand why one has to explictly call reindex_object when properties change, even though I think someone tried to explain it to me once). I suppose you could do something similar with non-catalog aware objects, where you made sure the add/update forms called the Catalog to index them, but they wouldn't get deleted from the catalog automatically, or reindexed automaticaly when moved. If you are writing your own management screens for those operations, though, you could make it all work, I think.

No limits other than those imposed by the OS file system (ie: Linux is currently limited to 2GB Data.fs files). If your large objects are static, placing them in the ZODB is reasonable. If they are dynamic, then your Data.fs is going to grown *fast* (a new 15MB chuck for every change to the object). You might want to look at the LocalFS product, which allows you to serve files out of the local file system through Zope.

It is responsible for creating (and managing) Foo objects. In the FooManager ZClass, I created a DTMLMethod called 'addFoo', and a form called 'fooForm'. Following the "How to Create ZClass Instances Programmatically" How-To, I modified my 'Foo_add' constructor to avoid redirecting if the request contains a noRedir parameter. In my 'addFoo' method, I have: dtml-with "manage_addProduct['FooProduct']" dtml-call "Foo_add(_.None, _, noRedir=1)" /dtml-with and I set it's Proxy role to 'Manager'. My form, obviously, calls 'addFoo' with: form action="addFoo" method="..." When I submit the form, I get: Unauthorized. You are not authorized to access FooObject.

I thought the Proxy role in the ZClass's 'addFoo' method would do the trick, but it did not. Sorry if I haven't explained this well.

[Zope] 2.2 and ZLDAPConnection - editAttributes fails.
Has anyone succeeded in getting ZLDAPConnections to work with Zope 2.2?
When I try to perform an edit on an Entry object, the edit appears to
work. However, the transaction is never committed to the LDAP server.
Also, when doing the examples from the Howto, I have to explicitly
call the Entry object's get method rather than using the attribute
directly. For example:
dtml-var uid will fail
dtml-var expr="get('uid')" is successful

Obviously, "ns_entrydate" is an object and it has no "__getslice__".
The name suggests, that it is a date object, probably a "DateTime.DateTime"

(probably ".Day()" or ".day()" etc.).

[Zope] server dies
I was wondering if anyone else had experienced this problem: Ever since we installed the ZPoPy database adapter, the server has been occasionally crashing, and it gets worse and worse over time. Has anyone else experienced this problem? We're running Zope through Apache, on a Solaris box, with PostgreSQL. I'm really curious as to what could be causing this behavior. I know that that adapter is still in development, but it seems like that would be non-desirable behavior :) If there is some way that our setup is causing this, any input would be appreciated. We are also still running the last stable release of Zope (2.1.6, I think) with plans to upgrade next week.

[Zope] From a Folder to a Product
Hi! I'm pretty satisfied with a group of reports I have done in Zope, and want to put a copy of it in every customer's folder I have in the Zope Server. Are there a document/tutorial I can use as a guide or tutorial to do this? If someone wants to point some general guidelines, the folder contains only the dtml docs/methods and SQL connection/SQL Queries used to do the report, and the only thing that changes from one to another customer is the SQL connection (every different customer have his own database).

Re: [Zope] dtml-tree question

Is it because the document is at the top of the namespace stack instead of
the
request object in the dtml document case, but not in the dtml method case?
Hurm, thinking for the right words and I think(?) namespace is the right
one.
Anyway, DTML documents have one and DTML methods don't.
Hence your tree tag is using the DTML documents namespace, which has
nothing in it apart from the properties of the document.
I don't think that's entirely accurate. There's a lot more in the namespace of a
DTML document. I think you're right, though, in that it's a namespace issue. I
found that the results of the SQL query where not part of the namespace in the
DTML Document case, but they were in the DTML Method case. Here's how I got it
working:
dtml-var standard_html_header
dtml-tree
branches_expr="select_subprojects(project_id=REQUEST.get('project_id',0)
id=project_id
dtml-call "REQUEST.set('project_id', project_id)"
smalla
href="edit_project?project_id=dtml-project_id;"edit/a/smallnbsp;
a href="view_project?project_id=dtml-project_id;"dtml-var
project_name/anbsp;/td
td align=right valign=topdtml-var task_count
/dtml-tree
dtml-var standard_html_footer
In other words, I have to explicitly get the parameter from the result object
and pass it back into the sql query. What I'd like to know is why? Is this a bug
or a feature?

Alex, Oracle 8i broke DCOracle's support for LOBs; DCOracle primarily
uses OCI 7 (Oracle 7) calls, and Oracle 8i enforces a restriction that
OCI 8 objects cannot be used in the context of an OCI 7 statement.
You can use Oracle 8.0 for this, the restriction isn't enforced until
Oracle 8.1.
