Converting Python Methods to Python Scripts
by Itai Tavor 15 Dec '00

15 Dec '00

Hi, I was wondering if anyone is planning to add automated migration of Python Methods to Python Scripts (maybe with Zope 2.3 final)? Or maybe there's something like this in there already that I missed? Anyway, for now I created a simple hack to do this - it's not pretty, but it works. In case anyone's interested, this is how to do it: * Create the following External Method at the top level of Zope, named M2S: from Products.PythonScripts.PythonScript import PythonScript from string import strip def M2S(self, ids, REQUEST): method_id = type(ids) == type('') and ids or ids[0] method = self._getOb(method_id) if method.meta_type != 'Python Method': raise 'HackError', 'Selected object is not a Python Method' title = method.title params = method._params if not type(method._body) == type(''): body = method._body.read() else: body = method._body self.manage_renameObject(method_id, method_id+'X') id = self._setObject(method_id, PythonScript(method_id)) script = self._getOb(method_id) script.ZPythonScript_setTitle(title) script.ZPythonScript_edit(params, body) return REQUEST.RESPONSE.redirect('%s/%s/manage' % (REQUEST['URL1'], method_i d)) * Edit lib/python/OFS/main.dtml. Find these lines: <dtml-if "AUTHENTICATED_USER.has_permission('Import/Export objects', this())"> <INPUT TYPE="SUBMIT" NAME="&dtml-id;/manage_importExportForm:method" VALUE="Ex port..."> </dtml-if> After them add this line: <INPUT TYPE="SUBMIT" NAME="M2S:method" VALUE="Convert Python Method to Script" * Repeat the last step for lib/python/Products/PlugIns/www/main.dtml * To use, check a Python Method in the management interface and click "Convert Python Method To Script". If you check more than one method, only the first one will be converted. * A new Python Script will be created, using the same id of the original Python Method. The old method will remain, with an 'X' added to its id. After the conversion you'll be redirected to the editing interface of the new script. Hope this is useful to anyone. It could probably be made much nicer, but why bother. Itai -- Itai Tavor "Je sautille, donc je suis."

Volunteer internship for Zope programmer
by Fred Wilson Horch 15 Dec '00

15 Dec '00

Dear kind Zope folks, If you are * computer literate, * interested in programming or already a programmer, * looking for a volunteer opportunity or an independent study project, * eager to publish code and work on a development team, and * able to invest a few hours a week between January and May 2001 reading, writing and documenting open source object-oriented web application software (specifically Java, C and Python code for Zope running on Linux), you may be interested in the attached announcement. Thanks for the bandwidth, Fred Wilson Horch mailto:fhorch@ecoaccess.org Executive Director, EcoAccess http://ecoaccess.org/ P.O. Box 2823, Durham, NC 27715-2823 phone: 919.419-8354 Spring 2001 EcoAccess Technology Associate Internship EcoAccess, a public charity working to enhance public understanding of our natural environment, is offering a volunteer Technology Associate internship program for people seeking the opportunity to enhance their software development skills. Selected Technology Associates will receive a loaner Linux system to allow them to develop free open source software for the EcoAccess database-backed web site. Designed for Associates who have some programming experience, the internship runs from January 8 through May 4. Our software is published on SourceForge and licensed under the General Public License. How to Apply The internship is open to anyone who has any programming experience or training, with preference to those residing in the Triangle area of North Carolina. Apply by e-mail to Fred Wilson Horch, Executive Director internship(a)ecoaccess.org Please include the following information: * Your name * Preferred e-mail address * A summary of your education and relevant work experience, if any * Your experience with open source software, if any * Your other time commitments between January and May If we are interested in working with you, we will request a code sample before making a decision whether to accept you into the program. More About the Internship Our Technology Associates will learn how to develop for Zope, a leading Open Source web application server. Part of the internship will be devoted to learning and improving Zope itself, including documenting aspects of its interfaces. The other part will be devoted to writing applications in Python, Java and C to support the charitable EcoAccess project. Technology Associates must have at least dial-up Internet connectivity. Four interns who are in the Triangle area of North Carolina (Raleigh-Durham-Chapel Hill) can receive fully-configured development machines for use during the internship. (Associates may also use their own Linux machines if they prefer.) The loaner machines are best described as tomorrow's software running on yesterday's hardware. Our Technology Associates will get hands-on experience building object-oriented transactional web applications. Specifically, our Associates will write programs in Java, C and Python that run on Linux and use PostgreSQL databases. This internship is made possible through the generosity of several members of the Triangle Linux Users Group (TriLUG) who donated the hardware for our loaner machines. We appreciate the help!

Please tell us, how it does not work (in fact, it should work): Did you get an attribute error (read) or was the result wrong? You must use the 'enctype="multipart/form-data"' and 'method=post' form parameter to upload files. Did you do that? Dieter

RE: [Zope] site structure

If you are like me, you like to keep your standard_html_[header,footer] fairly stock. I have started including dtml-method components in my pages like this: <dtml-var name="standard_html_header"> <dtml-var name="top_navbar"> *CONTENT HERE* <dtml-var name="bottom_navbar"> <dtml-var name="standard_html_footer"> Though, I have a difficult situation: If I understand correctly, definition of JavaScript functions belongs in the <head> tags. Does anyone know how to do this? Troy -----Original Message----- From: Jan H.

Together, they *are* your template. You *include* these in every document (using the <dtml-var standard...> tag. They'll show up in your documents at run time. Put the default template into the root folder and all your DTML documents will acquire it. In a sub-folder, you can either do nothing (then the acquired header and footer will be used), or override these with a folder-specicic template. See the Zope book, it explains it pretty well.

RE: [Zope] Windows NT, Zope, PostgreSQL, PoPy, and ZPoPyDA

Right now, I have PostgreSQL 7.0.3 on Cygwin: $ uname -a CYGWIN_NT-4.0 hostname 1.1.6(0.30/3/2) 2000-11-21 21:00 i686 unknown I followed the instructions found here: http://people.freebsd.org/~kevlo/postgres/portNT.html I haven't bothered with PoPy yet, but using the --with-odbc option seems to work. I am using the PostgreSQL 6.5 ODBC driver and am using ZODBCDA to connect to PGSQL over ODBC. I will keep you posted as I progress. Troy

Core Session Tracking Development Release 0.1
by Chris McDonough 14 Dec '00

14 Dec '00

Hi, A development release of the fruits of the "core session tracking" Fishbowl project (http://dev.zope.org/Wikis/DevSite/Projects/CoreSessionTracking/FrontPage) is available at http://www.zope.org/Members/mcdonc/Products/CoreSessionTracking. It allows you to keep state across requests for anonymous users (much like FSSession, SQLSession, HappySession, etc.), but it is capable of storing sessioning data in the ZODB or in RAM. You need to be running a pretty recent Zope 2.2.X to use it. I've tested it continually against the current trunk release, and it works against that. Feedback appreciated! Thanks, Chris

As others told you, you can use a header and footer to standardize layout. The header would define the top and left part of your site (i.e. your first table column); the bottom your right part of the site (i.e. the third table column) and the bottom part. The content between header and footer would define the center of the page (i.e. your second table column). If this does not provide enough flexibility, you can look into ZClasses. The page specific content would go into properties or content items of the ZInstances. The ZClass' "index_html" would combine all these elements into the final page. Dieter

I have read in this list (-> searchable list archive), that Shane's ZDebug product can help to analyse access problems. I had never need to try it for myself, though. Dieter

I expect the "manage_editProperties" is the culprit. I further expect that neither of your classes has a "manage_editProperties". Therefore, the "manage_editProperties" of the enclosing folder is acquired. It changes the properties of this folder. Dieter
