----- Original Message ---- From: Chris Withers <chris(a)simplistix.co.uk> First up, rifling through my trash, I noticed a response of yours to a previous email that I missed. Concerning the line of my script: try: mailhost=getattr(context, context.superValues('Mail Host')[0].id) what should I substitute for "Mail Host" if I want to call Maildrop? I tried "Maildrop Host" but for some crazy reason the script redirected to a slightly different URL and threw an error. (That URL should have worked anyway due to inheritance, so I don't know what's up.) This is the information in the Maildrop README that wasn't helpful in this regard: - Now you can create emails using e.g. the dtml-sendmail tag and point the sendmail tag to the Maildrop Host instance using the mailhost="XYZ" argument inside the sendmail tag, or by using the MailHost API (see the Zope Help System). Now, the rest ;) > Not really, it's a snippet for inserting into zope.conf alongside the > other logging configuration. You appear to have chopped off the %, which > you need to make it a valid zope.conf import statement. Okay, corrected and entered into zope.conf Yes, Chris, the below is, in fact, my zope.conf file. I inherited this box. All I can tell you is the below code does, in fact, work. I've added yours to it and now we'll see if they play nicely together ;) I am running Zope 2.7.8. I welcome any suggestions, of course :) > # Zope zctl settings > ZOPE_HOME = pjoin(HERE, '../..', 'ZopeSoftwareHome') > ZOPE_OPTS = '-p - -D' > ZOPE_PORT = 7080 > ZOPE_LOG = pjoin(HERE, 'var', 'debug.log') > ZOPE_ENV['PRODUCTS_PATH'] = ("%(SOFTWARE_PRODUCTS)s:" + pjoin(HERE, '..', 'OtherProducts') + ":%(INSTANCE_PRODUCTS)s") > > ZOPE_ENV['STUPID_LOG_FILE'] = ZOPE_LOG > # ZEO Environment settings > #ZEO['ZEO_SERVER_NAME'] = 'www.example.com' > ZEO['ZEO_SERVER_PORT'] = 9999 > # ZEO zctl settings > ZEO_WAIT_BAILOUT = 160 # Don't try for more than num seconds TIA, Nancy

i18n tags in XML file using Page Templates
by Daniel de la Cuesta 13 Nov '06

13 Nov '06

Hi everybody, I am want to return an XML file with i18n tags using a page template. For example: <?xml version="1.0" encoding="UTF-8"?> <language xmlns:tal="http://xml.zope.org/namespaces/tal"> <value i18n:translate="">My value</value> </language> When I use the i18n tag inside the page template I get a compilation error. The problem is exactly in the line where the i18n tag is. I have tried to include the i18n tal namespace but the problem persists. How can I generate the XML inside the page template using i18n tags??? Thank you!!

__bobo_traverse__ help
by Garito 10 Nov '06

10 Nov '06

Hi all! Please consider this code: def __bobo_traverse__(self, REQUEST, name): obj = self.Propiedad(name) if obj is None: return self else: return obj def Propiedad(self, propiedad): obj = getattr(self, propiedad, None) if obj is None: return obj # Añadir busqueda al catalogo else: if type(obj) == type(str('')) and obj.startswith('[') and obj.endswith(']'): return self.Expresion({'Expresion': obj[1:-1]})['Resultado'] return obj I wonder why I can do: <tal:b tal:replace='python: here.Propiedad("Modificacion")' /> but not: <tal:b tal:replace='here/Modificacion' /> Where Modificacion is a property that starts with '[' and ends with ']' and Expresion is a member who evaluates the expresion as a TAL expresion and put the result in a dictionary with the key 'Resultado' When I try here/Modificacion an unauthorized error trying to access Modificacion Can you explain me what is happening, please?

What is an InvalidObjectReference?
by Garth B. 10 Nov '06

10 Nov '06

Hello everyone, I'm sporadically getting the following error thrown as a result of a routine I've written. InvalidObjectReference: Attempt to store a reference to an object from a separate connection to the same database or multidatabase. I can often run this routine several times without a problem. After a fresh Zope (re)start, this error never happens on the first run. Once the problem does occur I need to restart Zope to make it go away. Can anyone tell me what this error actually means, and what bad practices could cause it? I've found a couple of hits about "InvalidObjectReference: Attempt to store an object from a foreign database connection error" in the archives, but I don't know how close this is to my problem. An example traceback would be: ----------------------------------------------- 2006-11-08T16:47:49 ERROR Zope.SiteErrorLog http://localhost:8080/WebSites/dev/test1/manage_publish Traceback (innermost last): Module ZPublisher.Publish, line 115, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 41, in call_object Module Products.DWT.WebBase, line 756, in manage_publish Module Products.DWT.WebBase, line 724, in manage_publish Module OFS.CopySupport, line 564, in _getCopy Module transaction._manager, line 110, in savepoint Module transaction._transaction, line 295, in savepoint Module transaction._transaction, line 292, in savepoint Module transaction._transaction, line 675, in __init__ Module ZODB.Connection, line 1012, in savepoint Module ZODB.Connection, line 526, in _commit Module ZODB.Connection, line 553, in _store_objects Module ZODB.serialize, line 407, in serialize Module ZODB.serialize, line 416, in _dump Module ZODB.serialize, line 341, in persistent_id InvalidObjectReference: Attempt to store a reference to an object from a separate connection to the same database or multidatabase ----------------------------------------------- I'm only dealing with one ZODB, so perhaps this is a multiple connection issue (although I have no idea how/why). In case it helps to know the context of the problem, I have a collection of objects I've written: 1) WebSite, based on OrderedFolder 2) WebSection, based on OrderedFolder 3) WebPage, based on ZopePageTemplate 4) WebImage, based on Image. Each of these classes inherit a common base of functionality from a WebBase class. The manage_publish() method, defined in WebBase, copies the current object (one of #'s 2-4) to the same relative path within the context of another WebSite. This gives me a basic "dev" to "live" publishing process. Perhaps the most complex part of this routine is its ability to recurse. For example, a WebPage on the dev WebSite will first call its parent WebSection's manage_publish() if the parent WebSection doesn't exist on the live WebSite. Other things do happen during the process which might be causing this InvalidObjectReference, but if I can get a grip on what kinds of programming offenses causes this exception then I can make a more educated review of my code. I will happily provide a copy of the source if anyone is interested or thinks it will be useful. Thank you for any help or advice! Garth

Troubleshooting Maildrop Host
by Nancy Donnelly 10 Nov '06

10 Nov '06

102Hi; I can't get Maildrop Host to work. I have a working SMTP, Python 2.3.5, Zope 2.7.8, and am running FreeBSD. I've edited the config.py file thus: PYTHON="/usr/bin/python" MAILDROP_HOME="/tmp/maildrop" MAILDROP_SPOOL="/tmp/maildrop/spool-1; /tmp/maildrop/spool-2; /tmp/maildrop/spool-3; /tmp/maildrop/spool-4" MAILDROP_VAR="/tmp/maildrop/var" MAILDROP_PID_FILE="/var/run/maildrop/maildrop.pid" MAILDROP_LOG_FILE="/var/log/maildrop/maildrop.log" SMTP_HOST="localhost" SMTP_PORT=25 MAILDROP_INTERVAL=120 DEBUG=0 DEBUG_RECEIVER="" MAILDROP_BATCH=0 MAILDROP_TLS=0 MAILDROP_LOGIN="" MAILDROP_PASSWORD="" WAIT_INTERVAL=0.0 ADD_MESSAGEID=1 I've fired up ./start_maildrop from the Products/Maildrop/maildrop/bin folder and a ps wax|grep maildrop yields a favorable result. I've added an instance of Maildrop through the ZMI. It appears I can reach the mail host because I use this code in my script: try: mailhost=getattr(context, context.superValues('Mail Host')[0].id) except: raise AttributeError, "Can't find a Mail Host object" and the error is not raised (rather, an error from a following page is raised, although perhaps I'm mistaken here?). Yet, when I go to fire up the script, the email is not sent. What am I doing wrong here? TIA, Nancy
