Nice! I like that! But I'm confused on one thing. In your instructions, you say: import Products.MailingLogger I assume that's at the instance level, where the zope.conf file is? That's a command, correct? Not something entered into the zope.conf file. I issued that command at the prompt and got this: # import Products.MailingLogger import: unable to open X server `'. Is there something I should edit first? Like zope.conf? Your instructions seem to indicate first issue the command, then edit zope.conf. And I'm confused as to if I should be editing zope.conf or something else, because my zope.conf file doesn't look like, for example, an httpd.conf file, where one would have syntax similar to what you propose. Here's my zope.conf: # 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 Also, can you tell me how to enter a variable into the eventlog "to" email address so that I could change it in a file on the server whenever I wanted to? I've been wondering how to do that. TIA, Nancy

Can't Track Simple Bug
by Nancy Donnelly 09 Nov '06

09 Nov '06

7474Hi; I have two Zope instances. On one of them, I have a boilerplate script that I use for all my clients' Web sites. Works fine. Has for years. I decided to copy it over to my other instance and I get an error. Here's the line in question: <p tal:on-error="string: mailScript() isn't defined! This should be in your *s* dir with the default installation." tal:replace="structure python:here.mailScript()" /> When the page that has this code in it is called by a form (that has the *s* directory in the URL), it throws the tal:on-error message. Even if I surf directly to that page and put the *s* dir in the URL, it still throws the error! Even if I rewrite the tal:replace to accommodate the dir: here.s.mailScript() How in the world is it doing that? The script also lives in that dir. Strange... TIA, Nancy

Silly me! I got so caught up in that error that I didn't think to check the error log! It said it couldn't find a Mail Host. Now, on the first instance, I just added the regular plain vanilla mail host, but on this instance, I got fancy with a Maildrop Host. Well, it didn't like that. It took the regular mail host just fine. But why didn't it like maildrop? Thanks, Nancy

Extra Fancy Template Manipulation
by Edward Pollard 08 Nov '06

08 Nov '06

Hi all, I've got three subsites that formerly used three different templates. I'd like for them now to use the same template, but I'd prefer not to have to touch the thousands of pages of content that currently point in three different places for their template. The easy solution is to copy/paste the template to three different places. But I don't like that solution. It will be obnoxious in the long run. I've never tried to manipulate templates and the execution of said templates with Python. Is there something I can do here to pass calls for the templates back to one place rather than actually duplicating my template? Cheers, Ed

I yahoo'd (can't google any more since they've sold out to the interests gathering our personal data for Homeland Security) "put_factory" and got this code snippet: if ext == 'dtml': from OFS.DTMLDocument import DTMLDocument return DTMLDocument( '', __name__=name ) So...how would I rewrite that to change it into a page template? And, more importantly, where is the documentation to do so? Yahooing didn't help on this. I went to my Zope installation to: {INSTALLATION}/lib/python/OFS to hunt around, but no script pointing to some "PTDocument" like there is with DTML. TIA, Nancy

Looking in that I find these two files that *might* be appropriate: PageTemplates.py ZopePageTemplates.py The latter is a wrapper for the former. The former defines the following class: class PageTemplate(Base): If this is the class I want to use, why only one argument? My example above cites exactly two arguments. And it is not a "base" I need to pass, is it? The latter defines the following class: class ZopePageTemplate(Script, PageTemplate, Historical, Cacheable, Traversable, PropertyManager): Why so many arguments? It doesn't look like those are any of the arguments I need to pass. None of the other files in that folder appeared to make sense, either. I confess I'm still quite green at programming, so if I'm wrong, please don't be too harsh ;) Any direction would be appreciated. TIA, Nancy
