- Medusa :: Zope consolidation ask.
by Sean McGerty 20 Jan '99

20 Jan '99

As something of a newbie lurker on the list... I was wondering on the Zope-Medusa consolidation project... They've got different liscencing requirements... will this change the requirements on either? Or will they be bundled together but liscenced seperately?

- Zope Example Formatting Field data indirectly via a TinyTable
by Brad Clements 20 Jan '99

20 Jan '99

Here's an example I thought you all might be interested in. Note that this is supposed to be Structured Text, however when trying to view it as such Zope reports an error with 'identifier' (seems it sees _['identifier'] for evaluation even though it's in "example code") Also, when I try to upload this, the upload process dies on the first  in the text. Btw, I don't know anything about python, very little about html and I've spent only about four days setting up Zope on my web site, most of that time was lurking in this list and being a pest. ;-) Anyway, here's the report. * Formatting Record Fields Indirectly Using TinyTable Data * While constructing my Zope based web site, I encountered an annoying problem displaying record field data. The problem: there are many record fields, I'm not sure what order I want to list them in, and I'm not sure how I want to format the fields. If I immediately began constructing an html table, it would take a lot of effort to re-arrange the table format or change the attributes. I devised a neat scheme to dynamically format the record data using a TinyTable that contains the names of each field variable, description and formatting information. I use two  dhtml commands, the first selects the desired record from my database, and the second selects formatting data from the TinyTable. This method allows me to arrange the data fields along columns or rows, or without even using a table at all. In my case, I chose to display record data in a table, where each field is in it's own row. The table output looks like this:: Owner's Name | Village Of Potsdam Address | Box 5168 | Potsdam, Ny 13676 Phone | 315-265-7480 Manager's Name | Brad Clements Address | Box 5168 | Potsdam, Ny 13676 Phone | 315-268-1000x11 Email Address | bkc(a)murkworks.com Airport Web Site | www.air.gen.ny.us The format of the TinyTable follows:: Id: AirportInfoFormatTable Title: Used to format AirportInfo display Columns: dbvar description format rowspan color Delimiter: : Data: OWN_NAME:Owner's Name:capwords::EvenColor OWN_ADD:Address:capwords:2:OddColor OWN_CSZ::capwords::OddColor OWN_PHN:Phone:asis::EvenColor MGR_NAME:Manager's Name:capwords::OddColor MGR_ADD:Address:capwords:2:EvenColor MGR_CSZ::capwords::EvenColor MGR_PHN:Phone:asis::OddColor MAILTO:Email Address:mailto::EvenColor URL:Airport Web Site:url::OddColor The TinyTable "AirportInfoFormatTable" defines the following columns dbvar -- The field name in the master database description -- Descriptive text format -- Controls how the master data is formatted rowspan -- Causes the description to span rows color -- Specifies the html class for each row A ZSQL Method is used to retrieve data from the master database using a select call through a ZODBC database connection. In the example code that follows, 'getall=1' is used to signal the ZSQL Method 'AirportLookup' to return all fields (i.e., select *). In the DHTML document code that follows, note the use of the _['name'] dhtml construct. This is replaced with the contents of the variable called 'name', however we're using _[dbvar]. Dbvar is a variable from our TinyTable, which contains each of the field names in turn, such as OWN_NAME. So _[dbvar] is replaced with the contents of the variable OWN_NAME when dbvar equals OWN_NAME. This is an indirect lookup of the field contents. Also, in the following example text, size=1 is used to retrieve only the first record from the ZSQL method. In my case, I only want the first record. Also, if the master data field is blank, we don't list it in the output table::   <table width=80% border=0>    <td rowspan= class= ><b></b></td>  <td align=left>    <A href="http://"> </a>  <A href="mailto:"></a>    </td> </tr>   </table>     Brad Clements, bkc(a)murkworks.com (315)268-1000 http://www.murkworks.com (315)268-9812 Fax netmeeting: ils://ils.murkworks.com ICQ: 14856937 We must come down from our heights, and leave our straight paths, for the byways and low places of life, if we would learn truths by strong contrasts; and in hovels, in forecastles, and among our own outcasts in foreign lands, see what has been wrought upon our fellow-creatures by accident, hardship, or vice. - Richard Henry Dana, Jr. 1836

- Importing images from subfolders in lowerfolders fails
by Brad Clements 20 Jan '99

20 Jan '99

I have a folder heirarchy like this / Air Links index_html I have an image in /Air called PlaneImage In /Air/Links/index_html I have  The resulting output HTML is <IMG SRC="PlaneImage" ALT="Small Airplane Image"> However, since PlaneImage is defined in /Air, shouldn't this really be <IMG SRC="Air/PlaneImage" ALT="Small Airplane Image"> I'm wondering if I'm using the #var wrong, or if this is a "bug". I'll have to hand-code all of my images if I can't get this to work. What is the var for "path to myself", is in, in index_html above I want to get "Air/Links" as the path, and "index_html" as the document name. To work around this problem, I've defined a property in /Air called "baseref" and set it to http://myhost.com:9673/Air" Then all of my URLS are constructed using , but it's rather labor intensive..

Hello, as far as i understand, only one process is created with pcgi. What if 2 clients send 2 queries simultaneously? Does one client wait until the other complete the request? how does it work? Thanks CLAIN Jephte Service Informatique CHSR ps: my apologies for my broken english, i'm a bit tired this morning.

- Problems adding documents
by Timothy Grant 20 Jan '99

20 Jan '99

Hi, I want to piggy back on my last message about not being able to upload documents using the upload tab. I have been attempting to Add a new document and I get the same error wheter I click on Add, or Add and Edit. The error I receive is: Exception happened during processing of request from ('127.0.0.1', 1544) 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 The really interesting thing is, I can add folders, products and external methods with no problem. I've added and worked with Tiny Tables GuestBooks and FSImport. All working great, I just can't get the very basics to work. Most frustrating. I'm running with ZopeHTTPServer on a Win95 box.

This is link to a very good and fresh review of discussion board software in ZDNet. It thumbs down for all existing software. I believe it can help people in Zopespot. At least can give some tips to do it right. http://www.zdnet.com/sr/stories/issue/0,4537,381684,00.html 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

- Other access control paradigms?
by BScherer＠mobile.bam.com 20 Jan '99

20 Jan '99

Having discussed this with Paul a long time ago in the Principia days, I believe this to be possible, but am unsure of where to start. The idea is this: I would like to maintain my user information (uid, passwd, and access info) in an rdbms table. This would enable us to leverage a database that already exits for this purpose. I have several bobo apps I would like to move into Zope, but I would need to overide (or integrate) Zope's internal security with mine. Reason being is that we don't want to move several thousand user's into Zope's user db, and we don't want to train the staff on a new interface/paradigm. I could change the backend of my security scheme without too much trouble. I don't want to have to change the frontend. Could this be as simple as an External Method? Or do I have to hit the Product API, or replace the entire AccessControl package? Thanks Bill Scherer Bell Atlantic Mobile

[ Discussion about using suid to allow Zope to run on port 80 ] > But I don't know how I can hand over a socket like > that... Especially not how Zope would handle it... Any ideas? My first response: Does Zope need to run on port 80 at your site? If you can run it on a port >1024, you will have a much smaller security hole. Regards, Jeff Bauer Rubicon, Inc.
