I followed the External Method howto by brian to the tee. But i get back these trace back errors: traceback (innermost last): File /home/whho/Zope/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /home/whho/Zope/lib/python/ZPublisher/Publish.py, line 179, in publish File /home/whho/Zope/lib/python/Zope/__init__.py, line 202, in zpublisher_exception_hook File /home/whho/Zope/lib/python/ZPublisher/Publish.py, line 165, in publish File /home/whho/Zope/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_addExternalMethod) File /home/whho/Zope/lib/python/ZPublisher/Publish.py, line 102, in call_object (Object: manage_addExternalMethod) File /home/whho/Zope/lib/python/Products/ExternalMethod/ExternalMethod.py, line 125, in manage_addExternalMethod File /home/whho/Zope/lib/python/Products/ExternalMethod/ExternalMethod.py, line 167, in __init__ (Object: upload_external) File /home/whho/Zope/lib/python/Products/ExternalMethod/ExternalMethod.py, line 186, in manage_edit (Object: upload_external) File /home/whho/Zope/lib/python/Products/ExternalMethod/ExternalMethod.py, line 195, in getFunction (Object: upload_external) File /home/whho/Zope/lib/python/App/Extensions.py, line 205, in getObject (Info: ('/home/whho/Zope/Extensions/upload.py', 'upload')) SyntaxError: (see above) I can't understand it. The filename I entered (without .py) is correct and even i follow the Function name in my upload.py which is upload_external. I'm loss. I'm using zope2-1-1 binary from zope.org and running under Mandrake 6.0. Help please!

Do I force it >into a list on the input form? I don't know whether this is the same problem I had recently or not. But, anyway, for the <select ... multiple> tag, you are almost surely better off if you specify the ":list" switch in the name. That is, change NAME="styles" to NAME="styles:list". This way, it won't freak out when a single item is selected. The reason is: when a single item is selected and you don't have the ":list" suffix, the form returns a string instead of a list of one single string. I have no clue whether this is problem of HTML/Python/Zope... (I asked the question but got no answer, sorry.) <SELECT NAME="styles:list" size="4" multiple> <OPTION VALUE="" SELECTED>  <dtml-in styles_list> <OPTION VALUE="<dtml-var sequence-item html_quote>"><dtml-var sequence-item> </dtml-in styles_list> </SELECT> hope this works, Hung Jung ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

calling ZSQL "in place"
by Timothy Wilson 05 Jan '00

05 Jan '00

Hi everyone, I'd like to print the total number of records in a database table and print that number on my page. My ZSQL method looks like: SELECT COUNT(*) FROM foo_table The method returns the correct number when I test it. I'd like to print the following: There are [insert SQL result here] records in the database. Using <dtml-call "foo_sql(REQUEST)"> doesn't work. Ideas? BTW, I've very impressed with the SQL tools that Zope has. Obviously, I'm new to using SQL with Zope, but the Z Search Interface Wizard was an absolute God-send. I'd be nowhere near as far along as I am without it. Now if I could just find my Zen... :-) -Tim -- Timothy Wilson | "The faster you | Check out: Henry Sibley H.S. | go, the shorter | http://slashdot.org/ W.

RE: UPDATE: Apache + ZServer complete solution... will it work with SSL?
by Clarence T. Pate 05 Jan '00

05 Jan '00

I like the mod_proxy solution better than pcgi or fast_cgi, but I need to authenticate users with X.509 certificates. Mod_ssl will allow Apache to pass through the certificate information to zope using zope.cgi (I believe this works, but I have not tested it yet). "SSLOption ExportCertData" will create environment variables for use by cgi/ssi scripts. Does anyone know if mod_proxy will also pass these environment variables to zope? Thanks, Clarence T. Pate

Sure - if nowhere else, NotMail2 certainly does email (it's a Zope-based mail user agent.) I've also got a SendMailTask in my workflow code. When it's preconditions are true, it sends a piece of email to the specified person (or to the email address(es) in whatever variable - it's just DTML) and then automatically goes to state 'complete'.

What does "this()" return?
by Hung Jung Lu 05 Jan '00

05 Jan '00

Hi, The "this()" method returns the object itself. Or at least that's what it's supposed to do. But if I have a folder named "myFolder" inside which I have a DTML method named "myMethod" consisting of the following lines: <dtml-if "this() == myFolder"> Hallo <dtml-else> Bye-Bye </dtml-if> The result is always Bye-Bye, when viewing myMethod. So the "this()" method is tricky. In the same league is the "id()" method, which is also tricky. And often I have to use "_['id']" to get what I want. The following works: <dtml-if "this().id == myFolder.id"> Hallo <dtml-else> Bye-Bye </dtml-if> However, this does not work: <dtml-if "this.id == myFolder.id"> Hallo <dtml-else> Bye-Bye </dtml-if> All these weird behaviors of "this()" and "id()" are sending my head spinning. When to use parenthesis, when not to use parenthesis, when to use "_['id']", when you can use ".", when you can't use ".", argghhhh.... Is there any doc on "this()" or "id()"? Aside from the "How-to..." docs, shouldn't we start compiling "Zope Pitfalls" or "Zope Gotchas" doc series? Sometimes learning a new software is not so much what you know to do, but what you know NOT TO DO. Also, is there any documentation on calling DTML methods with arguments? I know you can do it with "myMethod(_.None, _, arg1=val1, arg2=val2, ...)", but I'd like to know what the role of _.None is. (I know _ is the namespace...), that is, if I replace it with something like "myMethod(coolDude, _, ...)" what sort of catastrophe might happen. :) regards, Hung Jung ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

Has this been done?
by Jack Ungerleider 05 Jan '00

05 Jan '00

I am new to Zope (though I did experiment with Bobo a while back.) and being an ex-Notes programmer see some definite possibilities for Zope on the low end where Notes/Domino just is too costly. That said one of the core functions of Notes is messaging. I have look through all the sites I can find and all the docs that are obvious and can't find anything in the way of one-to-one (e-mail) messaging being done within the Zope environment. Has this been done? If so where can I find the code? If not do people think I'm barking up the wrong tree with this? Or does it sound interesting? My intent is to facilitate form based workflow applications that I think Zope (possibly with some XML) can do well. I appreciate the activity of this group. It helps to know there are a lot of people out there working on this platform. Thanks in advance for any assistance and/or ideas. -- Jack Ungerleider The Ungerleider Group Creative Solutions for Cooperative Computing jack(a)jacku.com www.jacku.com

Can anyone recommend good free or $$ tools for browsing the zope log? Is z2.log the only place that things are logged? Thanks, John
