Problem with Product example in 2.7 manual
by Jeff Gentry 27 Jan '05

27 Jan '05

Hello ... I've been following the Product creation example in the 2.7 Zope manual (at http://www.plope.com/Books/2_7Edition/CustomZopeObjects.stx) The very first portion has one create a trivial product which can be selected to add via 'Hello' and thus call the 'hello' method from earlier in the example. However, when I go to add this product, I get the login dialog constantly (yet I am already logged in) and if I hit 'cancel' to avoid it get the error: Error Type: Unauthorized Error Value: You are not allowed to access 'title_or_id' in this context Note that I have a stock/brand new zope instance that I'm working on and have not edited the permissions from the defaults in any way. Is there some permission change that I need to make for this to work? Thanks -J

As if any more evidence were needed that the current situation is untenable, I just attempted to figure out what Fred changed. The diff between the zope.org version and the plope.com version, according to diff -b -B, is now over 6203 lines long. There is no way in hell I'm going to sort that out. It feels too much like Fred and I are being punished for trying to help out. -- Paul Winkler http://www.slinkp.com

Re: [Zope] ZODB storage errors ...during object abort

Do I need to restart Zope, the database or refesh anything else ? Two other things: There is a flag that can be added to the connection string which manually enables or disables transactions; without flags, transactions are enabled if supported by the server, i.e. it has support for InnoDB (and not whether or not your tables are InnoDB, because it can't detect that). If you have something like that in your connection string, remove it; IIRC, it's + or - in front of the database name. It's a ZMySQLDA extension, so it won't work on other DAs. The other one should not affect you: MySQLdb-0.9.2 has issues with Python-2.2 or newer that affect Zope specifically (the infamous "server_capabilities" error). Newer versions (1.0 and 1.1 series) don't have this problem, but you appear to be using Python-2.1.3, so this should not be an issue. If it were, the product wouldn't work at all, unless you patched it manually to avoid the check, and since have forgotten about it. Please try ZMySQLDA-2.0.9b2 with MySQLdb-1.1.9. -- Computer interfaces should never be made of meat. Using GMail? Setting Reply-to address to <> disables this annoying feature.

I did indeed have 4 tables that were MyISAM rather than InnoDB. So I did an ALTER TABLE <tablename> TYPE=3Dinnodb; on all of the tables in question. However, I'm still getting these errors in my event log. Do I need to restart Zope, the database or refesh anything else ? also, the reason why I'm interested in this bug is that every couple of days, after seeing this storage error msg, Zope hangs, in the log files the hang is always associated with this error msg: "AttributeError: Surrogate instance has no attribute '_p_oid'" which i figured out is this bug. http://collector.zope.org/Zope/852, but the resolution is not clear. does anyone have any more light to shed on these ? thanks a lot, iroro Zope 2.6.4 (binary release, python 2.1, linux2-x86) Python 2.1.3, linux2) [GCC egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)] ______________________________________________________________________ Post your free ad now! http://personals.yahoo.ca

documentation defacement
by Mike Culbertson 26 Jan '05

26 Jan '05

Could someone with adequate access please remove at least some of the garbage posts from the zope docs, the thousands of lines of spam/vandal nonsense make it really annoying to read. example: http://zope.org/Documentation/Books/ZopeBook/2_6Edition/AppendixD.stx -Mike Culbertson

Recursively comparing 2 folders' objects
by Pascal Peregrina 25 Jan '05

25 Jan '05

Hi, I would like to know if anyone has some advice to give me on this. Inside one Zope instance, I have 2 folders, representing a live site and a development site. People copy objects from dev to live when they are ready. I would like to know if there are things to avoid (in order to speed up overall comparison time). I was thinking about a recursive function that would follow the development site folders structure, and on each folder, compare contents with live content, using comparison methods by meta type. Thanks a lot.

OFS.History (question 2)
by Pascal Peregrina 25 Jan '05

25 Jan '05

First of all, thanks Dieter, that answered my question 1. Now I've got a more serious problem. I have a CMF Document that wraps a PageTemplate object (it does not extend PageTemplate, but internally stores a PageTemplate instance). It looks like when some revision of my object is retreived from ZODB, this does not include the wraped persistent objects that my object may contain. For example, rev1._get_pt.read() and rev2._get_pt.read() always return the HTML of the current revision's wraped PageTemplate. (_get_pt() returns the wraped PageTemplate object) Is there a workaround for this ? The only thing I can think of is storing the PageTemplate HTML at my object level each time it is changed, but that means storing the HTML twice in ZODB... I tried it, and of course it works.

sql_delimiter broken?
by hpinson＠indepthl.com 25 Jan '05

25 Jan '05

The ability to pass multiple sql calls in one ZSQL method using sql_delimiter seems to be broken in 2.7.4. This no longer works in a single ZSQL method: INSERT INTO ...; <dtml-var sql_delimiter> INSERT INTO ...; <dtml-var sql_delimiter> Crashes the sql on encountering the sql_delimiter. Does anyone know of any workaround outside of using separate ZSQL methods for each statement? I know... convert it to Python.
