[Zope] Removing part of a string (in an URL)
Hi, more newbie questions, I am afraid. I have a ZCatalog result form that boringly forms links this way: Due to the way my site is organized, the URL I get has an unwanted part at the beginning. The part is always the same size, and the same string in fact. How do I remove it ? For example, the URL is http://zorba.com.mx:8080/Zorba/busca/Zorba/cacharrito/prueba ^ and I would like to cut it here | and turn it into /Zorba/cacharrito/prueba The problem is that the URL above is still valid, but if I do another search then the same /Zorba/busca gets added, and it gets longer and longer, besides messing up my breadcrumb trail. I tried using a regular expression method, but I do not really know Python (not yet !), so it did not work.

[Zope] Oracle 8i problem: OCIEnvInit failed
I'm having trouble figuring this out - I've got a zope 2.1.4 server that I'm trying to get to work with DCOracle 1.3.1 b1, ZOracleDA 2.2.0 b1, Oracle 8i client and Oracle 8 server on a RH 6.1 Linux machine. The DCOracle test routine *does* work - it connects and says as much. Within Zope I'm getting some frustrating behavior however. I'm starting Zope with the "start" script in an environment that has ORACLE_HOME set just as it was for the DCOracle test script. The product looks OK in the control panel. I can make an instance of it, but if I have "connect immediately" turned on Zope *dies* and I get "OCIEnvInit failed, oci_8.c:220" in the terminal that I started Zope on. If I have "connect immediately" turned off, I can create the instance. But whenever I try to connect I get the same problem - Zope dies with the OCIEnvInit failed error. Any clues folks? I'm seriously pressed for time here - anything you have would be most appreciated!

I tried that. You can't add a ZSQLMethod unless there is a connection for it to connect to. There isn't a connection in the products area.

Proximity searches are searches for terms that are near in the document. ZCatalog uses "..." as near operator.

This message comes from your browser not from Zope. The browser has received an empty HTTP response. This usually happens, when Zope dies during a request.

You do not pass the objects "par1", "par2" and "par3" but the literal strings 'par1', 'par2' and 'par3'. At least for "par3", this will not be what you want.

Zope should not be responsible for this strange behaviour. It simply executes the SQL statement and asks the result for the result column names. It then wraps each result row in an object that allows to access a column value as attribute under the respective column name. You could try: to get the list of column names your Z SQL Method "SQLMethod" returns. This may give you a hint how your database names result columns. I recently found out that Oracle returns column names converted into all uppercase. I needed about 2 hours to analyse this weird behaviour.

I've heard a suggestion I like a lot: send a hidden field in the form with a random but discernably unique value. When handling the form submission, before performing any other processing check whether that random value has already been copied to a small, persistent list. If the value is not there yet, add it and continue processing. But if the value is found, either stop the processing abruptly or somehow attach to the thread which is doing the processing and return its contents when it's finished. Note that you should not use ZODB persistence to store the list because each thread gets an independent view of the object database. The values should stay in the list for a few seconds beyond the end of the transaction, so you'll have to implement a basic garbage collection scheme.

ZClasses have a "property sheets" tab where you can add sheets. Group relevant properties together.

[Zope] Multiple clicks: how to handle them?
Hi, This must be a well-known problem: you click multiple times on a form button, and multiple requests are send to the server. On many websites they ask you not to click on the "confirm purchase" button twice, because otherwise you'll be charged twice. Of course, browsers are to blame for this fault. I can't believe Internet Explorer and Netscape are both faulty at this (on Windows platform), but that's the sad reality. (What the heck where these programmers thinking when they made the form requests non-blocking?!!) Anyway, how can one handle the problem from the server side? Session management is an obvious candidate. Every time you receive a request, you set a busy flag, and dump all the following requests, until the first request is properly finished. But this has two problems: (1) You'll see on your browser the response to your last request, not to your first request. (2) If you use RESPONSE.redirect(), your session is locked up. Of course I can go down into the transaction manager level of Zope and do things from there. But I'd like to know how other people handle the multiple click problem.

But I don't have good answers yet. I tried BEGIN and COMMIT when I didn't even have a database selected, and it took it. It may silently accept ROLLBACK when rollback is impossible, or it may raise an error. I haven't done that much testing with MySQL-3.23 yet, and none with BDB tables. But it may be possible to break things down as having a DA for 3.22 and one for 3.23.

Given the following hierarchy: /home header footer /content index_html /lowres header footer and a request of /home/content/index_html, we have the following acquisition path (assuming index_html is a DTML Method): /home/content= (content of home) /home/content/index_html = (index_html of (content of home)) Assuming index_html contains: Content. when index_html asks for header, the acquisition path is searched from left to right; the content folder is searched first, followed by the home folder, where header is found. Now, with a request of /home/lowres/content/index_html, we have: /home/lowres= (lowres of home) /home/lowres/content= ((content of home) of (lowres of home)) /home/lowres/content/index_html = (index_html of ((content of home) of (lowres of home))) Therefore, when index_html looks for header, the content folder is searched, then the home folder, then the lowres folder, then the home folder. Unfortunately, for our example, the header is found in the search of the home folder, and we never make it to the lowres folder. If, instead, we structure the request as /home/content/lowres/index_html, we have: /home/content = (content of home) /home/content/lowres= ((lowres of home) of (content of home)) /home/content/lowres/index_html = (index_html of ((lowres of home) of (content of home))) When index_html looks for header, we search lowres, then home, then content, then home.

My preliminary test indicates that indeed the deadlock is coming from the Sybase database adapter.

Zope does that if you are using the Transaction Manager. And the only way to control use of the Transaction Manager is by selection of DA. That's why I think it may be necessary to have two ZMySQLDAs: One which is transactional and one which is not. However, they can both be part of the same distribution, and the transactional one can simply subclass the non-transactional one (mixing in the TM base and adding the required methods), so there is not a lot of code duplication. In addition, a lot of people are still going to be using MySQL-3.22, which does NOT support transactions, or even the BEGIN/COMMIT/ROLLBACK statements (these produce syntax errors). The only way to detect this at runtime is to look at the server's version.

Using so-called "Internet programming". ;-)
If you 'view frame source' when creating a Zope File object, you'll
see that '', with
parameters 'id', 'title' and 'file'.
This means you can talk to it via http post. Executable pseudo-code
<0.5 wink> follows:
import urllib
user = 'zope_user'
passwd = 'zope_pass'
folder = '/path/to/my/folder'
action = '/manage_addFile'
url = 'http://%s:%s@myzope:8080%s%s' % (user, passwd, folder, action)
for fname in my_900_file_list:
dict = {'id':fname, 'title':fname, 'file':fname}
postdata = urllib.urlencode(dict)
u = urllib.urlopen(url, postdata)
The very act of "u = urllib.urlopen(...)" will create a Zope File object
with id and title set to the filename.
You don't have to do anything with "u", just loop around. Indeed,
if you try, say, u.read(), Zope will prompt you for username and password.
You'll probably need to make your filenames legal Zope identifiers, e.g.,
by stripping path separators.

[Zope] importing text files
I have a file object (a text file) in my project that is displayed in a dtml document. Is there a way to make that object dynamic, i.e. when a user changes the file (in notepad, or something) and saves it, those changes are reflected next time the dtml document is loaded.

[Zope] Proxy role bug (or feature)
Hi, I have encountered a problem with proxy roles with my product GuardedFile. A GuardedFile is a File that is accessible by proxy only. When a GuardedFile is created, all acquired permissions are unset and a proxy role is created in its container with the sole permission 'view'. In all other aspects a GuardedFile behaves like a File. Typically, the GuardedFile creator next creates a DTML method and assigns to it the associated proxy role. Anonymous and other users access the GuardedFile via the DTML method. I've discovered a problem with the product setup: Suppose user 'ngps' exists in the top-level user folder, and has the default roles 'owner' and 'manager'. 1. ngps creates a folder called 'junk' somewhere within Zope. 2. ngps switches to the folder 'junk'. 3. ngps creates a GuardedFile 'agf'. A proxy role 'proxy_for_agf' is automatically created in 'junk'. 4. ngps creates a DTML method 'view_agf' to access 'agf'. When ngps tries to assign the role 'proxy_for_agf' to 'view_agf', the following error is generated: (Slightly reformatted for readability.) You are not authorized to change 'view_agf' because you do not have proxy roles. Traceback (innermost last): File C:\pkg\Zope220b3\lib\python\ZPublisher\Publish.py, line 222, in publish_module File C:\pkg\Zope220b3\lib\python\ZPublisher\Publish.py, line 187, in publish File C:\pkg\Zope220b3\lib\python\Zope\__init__.py, line 221, in zpublisher_exception_hook (Object: view_agf) File C:\pkg\Zope220b3\lib\python\ZPublisher\Publish.py, line 171, in publish File C:\pkg\Zope220b3\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: manage_proxy) File C:\pkg\Zope220b3\lib\python\ZPublisher\Publish.py, line 112, in call_object (Object: manage_proxy) File C:\pkg\Zope220b3\lib\python\OFS\DTMLMethod.py, line 273, in manage_proxy (Object: view_agf) File C:\pkg\Zope220b3\lib\python\OFS\DTMLMethod.py, line 266, in _validateProxy (Object: view_agf) Forbidden: (see above) The following works around this: 1. ngps creates a user folder in 'junk'. 2. ngps adds a user in 'junk' called 'user2', with roles 'owner', 'manager' and 'proxy_for_agf'. 3. Login as 'user2'; 'user2' is now able to assign the role 'proxy_for_agf' to the above-mentioned DTML method 'view_agf'. This proxy role handling seems unwieldy, in that 'ngps' cannot assign the proxy role but can create another user 'user2' that _can_ assign said proxy role. Is this a bug or a feature?

RE: [Zope] MySQL Select Statements
I should point out that 0.2.2 has not been fully released yet. There's a
bug I have to iron out of it first. Probably next week. Also, for general
MySQLdb questions, send them to [EMAIL PROTECTED] (mailing list). Or
subscribe, it's low-volume and won't fatten your mailbox.

It's a matter of perspective. I prefer to think of it as 0.2.2 breaks
ZMySQLDA. This is because ZMySQLDA uses _mysql, and _mysql prior to 0.2.2
implemented fetch_row(), fetch_rows(), fetch_all_rows(), and the
..._as_dict() variants. This was just too much code duplication to put up
with, and the new interface is fetch([n[,how]]) where n is the maximum
number of rows to fetch (default 1), and how is how to return the result
(0: as tuple, 1: as dictionary, other codes may be added at some point).
To fix ZMySQLDA, change fetch_all_rows() to fetch(maxrows) in the query
routine. One other place (to get the tables) uses fetch_all_rows(). If you
insist on using 0.2.2 at this point, change that as well. 0.2.2 is marked
Alpha for a reason... And when I release it, I'll include a very small
patch to make things right with ZMySQLDA again (I'm treating mordred's as
the official one at this point).

Quite true. Now for the AS statement: If you are joining tables with
identically-named columns in common, you should use AS in your SQL to
rename them. Otherwise it will return two columns with the same name to
Zope, which is bad. You do not, however, need to do this:

This is just gratuitious renaming to the original name, which is not
renaming at all. Here's an example of what I'm talking about.
SELECT TableA.Col, TableB.Col from TableA, TableB # bad
SELECT TableA.Col AS ColA, TableB.Col AS ColB from TableA, TableB # good
Note that the first SELECT returned two columns named Col, which will
confuse Zope, and the second returns ColA (TableA.Col) and ColB
(TableB.Col).
Additional compatibility note: One of the 0.2.2 changes has been to
synchronize with MySQL-3.23 evolution (now at 3.23.19-beta, and GPL'd),
and the big feature here is: Transactions! Yes, as of 3.23.15,
transactions are in MySQL, if you use BDB tables. And yes, BDB does mean
Berkeley DB, specificially the Sleepycat DB v3, which supports
transactions (but probably not columns, which I presume MySQL is imposing
on the database).
For ZMySQLDA developers out there; MySQL-3.23 defaults to autocommit.
However, there is a BEGIN SQL statement which starts a transaction and
similarly for COMMIT and ROLLBACK statements. But remember: All this
transactional stuff ONLY works on BDB tables. If you try to BEGIN a
transaction (or turn off autocommit) on another table type, well, I'm not
sure what happens. Maybe you get an error, and maybe you don't. Not sure
what the solution is for this. It may be necessary to have the ZMySQLDA
package include another DA: ZMySQLTDA for transactions. The standard DA
would not be based on TM, and the transactional one could simply subclass
the other one:
# ZMySQLTDA/db.py
from Shared.DC.ZRDB.TM import TM
class DB(ZMySQLDA.DB, TM):
def _begin(self, *ignored): self.db.query("BEGIN")
def _finish(self, *ignored): self.db.query("COMMIT")
def _abort(self, *ignored): self.db.query("ROLLBACK")
Obviously the application designer will have to use the right DA for the
right table type...

See, when you have 900 files in one directory, > you need to scroll down each time.. so I suggest to put that box, you > know the box I mean ? Place it at the top of the page. Well, GOOD use of Zope is not to have 900 files in one directory, but to use acquisition and different folders for different objects or projects or sites. When I work with the Zope interface I realize that I spend more time on clicking the objects than the "Available Object" white box. What you could do is copy the HTML code to the "Available Object" white box and implement that into the menu (menu.dtml). Use some extra javascript to ensure that the focus is put in the workspace frame. A GOOD thing about Zope being Open Source is that you can tamper the interface for your needs if you want to. Me, for example, have created a list of all objects (not only the folders) below the tree in the menu frame. And I have the title of the object pop up in the status row of the browser. The purpose of that was that I sometimes forget what I named the object I created, when I am about to use it in a method of document in another folder. Even simpler would be to change the HTML source of the management interface yourself and cut'n'paste the "Available Object" white box above the list of objects. > ___ > 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 ) > ___ 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 )

I was trying to walk the fine line between providing too much detail and not
enough. Briefly, 'SB_B208' is an example of the type of string I'm trying to
parse. I do a string.split('l', '_') (where 'l' is the argument to the
string-splitting Python method) and get ['SB', 'B208']. 'SB' is one of the
two-letter codes that gets lookup up in the Tiny Table and 'B208' is an
office number. Together, these two strings represent a person's location in
our LDAP directory.
I don't understand where the weird tuple in the traceback is coming from.

'l' is passed to the Pyton Method. Examples would be: FH_123, SB_A231,
DO_111, etc.

I haven't been hearing of any hanging issues with the 2.2 betas, which makes me suspect that something specific to this site may be in play here. The fact that it comes back to life on its own after a while makes me think that this is either a very strange system issue or tied up with something that has a timeout (for ex. is it possible that a query is trying to run, timing out against the postgres database?)

It's a great idea but I've had some thoughts on this myself. I think the approach I would take is to create a ZClass. Content authors would create instances of this ZClass and would not have to use standard-html-header nor any other DTML if they don't want to. The ZClass would perform a simple transformation of the content before presenting it on the Web, such as adding standard_html_header/footer and including the title and date. > I also started to really groove on the idea of Object Oriented precepts > for my pages, and having to explicitly "#include" peices like the common > stuff offended those sensibilities.

The default style elements are in home. When the user browses to /home/content/index_html, they get the default style.

I have a slightly different take on the problem from back when I used to use mason. Autohandlers solve parts of this... An autohandler is a bit of code which would get executed during URL traversal. it's main use is to render a wrapper around a page, for example: ...do stuff... process and render the rest of the URL (called mc_auto_next in Mason) ...do mroe stuff... So your standard_ stuff apears in the autohandler and is _automatically_ wrapped around the eventual object. How far would this go to doing what you were talking about? Not far enough might be the answer...

Well, it might be the best way. Why? ...because otherwise you have to load up the whole object to get the attributes you want.

[Zope] FOR loops?
This ought to be easy: through a list of entries. Each entry has a string and a number which indicates its level of indentation, so "Root",0; "Main",1; "Sub",2 and so on.

The error means you're trying to split up a string, but the argument is
no string, but an instance (a Python Object). In many cases this is
caused by an omission of parenthesis, like so
called_object instead of called_object()
in which case the object is referenced instead of called and nothing is
returned (of course). I did not find the culprit in your description,
though.

I do not quite get what part you want to parse. Is it 'SB_B208'?
accessing this in python is a bit strange due to the returned value. You
get to the 'SB_B208'part in the following way:
whateverreturnstheresult()[0][0][0], meaning (in this
case):
the first element (of the list) of the first element (of the first
tuple) of the returned tuple

I may be reading badly, but can you explain what the l is (or is

LocalFS happily uses the If-Modified-Since header, so an http cache (I use Squid, http://www.squid-cache.org/) can cache LocalFS content outside of Zope. This assumes you are using LocalFS to serve whole files over http, rather than processing those files inside Zope.

[Zope] ZClass in ZClass problem
Hello! I started to learn ZClasses. I created a product, added a Zclass in it, and added a Zcalss inside outer ZClass - I want to create ZClass that's addable only inside outer ZClass. Then the problems begin. All management URLs for inner ZClass contain %20, so URLs look like "propertysheets/methods/RandomZItem%20/manage_workspace" and "propertysheets/methods/RandomZItem_add%20/manage_workspace". If I click on the link I got the AttributeError (of course). When I manually remove the offending %20, I can manage the object, but it's tiresome to remove it every time. The problem manifested on both 2.1.4 and 2.2.0b3. What's wrong?

Um, perhaps a stupid question, but can it use other ports for ftp and/or can you reach the server? If so, you can easily change the ftp port in the z2.py program in your zoperoot (it's heavily annotated, so that shouldn't be a problem). As to loadsite, is there an error message (or a traceback) with which it closes loadsite? If the window closes too fast you may need to run it from a dos window.

[Zope] ZCatalog Search Q
Hi, I'm trying to search a catalog and return a list of hits, and here is a code fragment: "> This works ok, however, I understand that the catalog search does not actually return object references to the actual objects catalogued. I'd like to include some attributes from the actual objects (maybe by accessing the actual object via id, etc?) in the result list. Can someone let me know how to do that? I can of course include those attributes in the catalogue meta table so they would be returned with the search results, but I don't really want to do that unless there is no other way.

[Zope] Error handling and super users....
Hi, A couple of questions...: a) is there a way of sending an error to a default object other than standard_error_message? For example I would like errors of type x to be handled by one object and y by another. Obviously most objects should have their own error handling that makes sense, but a there are few special cases when I can see it being useful. The most obvious method is to put a big dtml if inside the standard_error_message and send the errors to those objects. But does anyone know of a more elegant solution (if not I can see a potential product in there)... b) anyone know a way of restricting the super_user to a domain? Zope allows you to restrict users, but I would like to tighten down Zope a little more by only allowing super_users from within our domain... Thanks in advance.
