- Best way to input validation

Oops, excuse me for the incomplete message. Here is the correct one: Hi, I've just notice that I had a misconception about how Zope handle input data validation. I thought it were possible to handle the errors, but it looks like we are doomed to show to the user the python traceback. I believe now that the way to go is to forget the :int and :required specifiers in form attributes and directly code the validation code. Am I right? If so, then besides prototyping there's no use to these specifiers. Is there a best way to validate input form data? regards, -- Paulo Eduardo Neves PUC-Rio de Janeiro Pager: Central: 292-4499 cod. 213 99 64 ou use a URL: http://www.learn.fplf.org.br/neves/mensagempager.html

Your email this weekend finally prompted me to make the decision on Tabula and to announce our intentions on doing a Zope-Slashdot. Here are my plans with this regard: 1) Create a mailing list for "Zopespot", the name of the community project that coordinates this. 2) When Ken gets here, make him the shepherd for the project. 3) Publish my stab at the requirements document. 4) Turn the zope.org site into a legitimate contender for best portal/community site on the Internet. We intend to invest pretty heavily in making the Zopespot software and the content on zope.org a shining example. 5) Work with others (lwn.net, python.org, etc.) to offer it. > I have looked at the Slashdot source code (in perl) and its > pretty messy > (to put it mildy).

For searching? With the Tabula software available for the Zopespot project, I think you'll be pretty impressed. I loaded a 23 Mb portion of the Internet movie database into a Tabula on my P166 laptop with 64 Mb running NT. Search times for a combination fielded/full-text search came back in under a second. Tabula, which is under the tutelage of Jeffrey Shell here, is a serious piece of gear. Briefly, I see Zopespot as filling the following goals: o Well-organized site with discoverable, timely information. o Harness the energy of contributors. o Apply editorial control. o Provide added value for members. o Demonstration of software potential. o Lower our admin burden while raising scalability. o Integrate many kinds of resources. o Adhere to applicable emerging standards. Zopespot could manag the following kinds of Items: Packages, Documents, News, Projects, BugReports, FeatureRequests, Members, Discussions, CaseStudies, BuzzReports, JobListings, Polls, Ads, etc. Each Item will support and expanded Zope Framework protocol for managed content: id, title, category, keywords, last_update, owner, meta_type, isVisible, summary Users will have a variety of ways to browse and search content. > Building the Slashdot-style site on Zope has the attractive feature of > being very customizable and modular from the get-go (something which > Slashdot source code is trying to get to).

Do we have to wait The current Zope software with Tabula outta beat that pretty easily on a reasonable hardware.

I'm a BIG fan of organizing the requirements before marching off on such an ambitious project. --Paul Paul Everitt Digital Creations paul(a)digicool.com 540.371.6909

- Disregard the previous "proper move method" message

The problem was that I had also moved a subolder to the root folder, but forgot to copy several properties to the root folder. I notice that the properties page does not have cut/copy or paste.

- What is the proper way to migrate a Zope Server?
by Brad Clements 18 Jan '99

18 Jan '99

I'm trying to move my win32 ZHTTPServer Implementation of Zope to a new machine and directory. Moving from E:\Program Files\ZopeOne to another machine in D:\ZopeOne I copied the ZopeOne directory tree, changed the start.bat and serve.py file. The manage interface works, but when I try to view my index_html files, I'm getting an error (traceback below). Note the incorrect paths in the traceback (referring to E:\Program files) I uses find from the manage interface to search for E:, can't find it. I grep'd my files, can't find it. Note that I did NOT run the Zope installation script on the target machine, is that the problem?

As indicated in the roadmap I just sent out, the pieces of Tabula that provide scale and searchability are going to migrate their way into Zope. In the near term the only documentation for it will be with Tabula. The plan for Tabula is to make it available to a small audience at first. The main reason is that, until we bring on some more staff, our plate is pretty full supporting (and documenting!) what we already have out there. The audience will be limited to people that are working on projects that we can write case studies on. --Paul Paul Everitt Digital Creations paul(a)digicool.com 540.371.6909

- MultiUser Gadfly
by Randall Marbach 18 Jan '99

18 Jan '99

I am interested in using Gadfly as a backend to Zope. I am planning to have a non zope background process write data into Gadfly and have a Zope process retrieve and display this data at the same time. Is this possible to do with Gadfly? Does Gadfly have to use client server mode? Does Zope support this type of activity?

- Error uploading a file using the upload tab

Hi, For starters, I want you to know that I have figured out the FSImport thing, that I posted about earlier (I hate to admit this but I had mismatched case between its name and my request!) Secondly, while trying to Upload some HTML source using the Zope Upload tab I got the following error using the ZopeHTTPServer Exception happened during processing of request from ('127.0.0.1', 1403) Traceback (innermost last): File "C:\DevTools\Python\zope\ATGWeb\ZopeHTTPServer\ZopeHTTPServer.py", line 4 19, in handle_request self.process_request(request, client_address) File "C:\DevTools\Python\zope\ATGWeb/lib/python1.5\SocketServer.py", line 239, in process_request self.finish_request(request, client_address) File "C:\DevTools\Python\zope\ATGWeb/lib/python1.5\SocketServer.py", line 243, in finish_request self.RequestHandlerClass(request, client_address, self) File "C:\DevTools\Python\zope\ATGWeb/lib/python1.5\SocketServer.py", line 362, in __init__ self.handle() File "C:\DevTools\Python\zope\ATGWeb/lib/python1.5\BaseHTTPServer.py", line 25 8, in handle method() File "C:\DevTools\Python\zope\ATGWeb\ZopeHTTPServer\ZopeHTTPServer.py", line 3 22, in do_POST if string.find(self.headers.getheader('content-type'), TypeError: argument 1: expected read-only buffer, None found ---------------------------------------- This is on a Win95 box.

Hi All, PART1 --------- Good, query a gadfly database (select for example) with the general above way works fine, thanks! The general way to do things is to make a Document the target of the form action. Then have that Document interact with the SQLMethod and return some HTML.

- Help with Zope . . .
by David Wagle 18 Jan '99

18 Jan '99

I'm looking for some detailed help, being new to both Zope adn Python, and I'm hoping someone here can take the time. I would like to use Zope to help build a procedures database system for our company (about 8k employees). The starting project is a much scaled down goal of providing for a procedures database for the dozen or so IS people. I have a mysql database, and a Zope page that will allow me to insert data into the page. What I need to figure out how to do is: a) login the user to the system and GET that information for the DHTTP script. b) create a new UNIQUE folder for the created procedure username+DateTime.timeTime pehaps c) provide a way to upload the procedure (an HTML page & associated images adn/or files) to the new directory FROM THE PAGE that gets the information about the procedure for the database. If I could figure out 'a' from the documentation (which I've yet to do correctly it seems), I could figure out b . . . since the O'Rielly python text has some very clear examples in it. I am clueless as to how to do 'c.' I figured out how to use the netscape "Publish" feature to 'PUT' a page once you know the URL, but I would like it to be more 'automagical' than that. I would like the user to just be able to give the local path (on their machine) to the base page, and have it and all the associated files moved over. Some pointers would be great. Thanks, Dave (not looking forward to learning far more about HTML, HTTP, and CGI than he ever really wanted to know :)
