I'm curious - has anyone compiled Zope to run on LinuxPPC ? Should be do-able right ? cheers, darcy -- --------------------------------------------------- Ph: (734) 764 3377 Email: darcyc(a)engin.umich.edu URL: http://www-personal.engin.umich.edu/~darcyc/ --------------------------------------------------- 'If you're not part of the solution, you're part of the precipitate' .....

Follow-up question about calling stored functions with OracleDA
by Jim Cain 13 Jan '00

13 Jan '00

Okay, I've managed to call a stored function. It looks like this: declare new_id number; begin new_id := contact_maint.insert_person ( <dtml-sqlvar first_name type=nb optional>, <dtml-sqlvar middle_name type=nb optional>, <dtml-sqlvar maiden_name type=nb optional>, <dtml-sqlvar last_name type=nb optional> ); end; Now the next question is: How do I return "new_id" so I can refer to it inside a <dtml-in></dtml-in> call to this SQL method? Thanks, Jim

Zope and PostgreSQL
by Cesar A. K. Grossmann 13 Jan '00

13 Jan '00

Hi! I'm a clueless newbie to this world of Zope, Python, etc. I need to deploy some reports to the Internet, from a PostgreSQL database. Where I can find some information about it, in the Internet? I need only the links, but if someone wants to post a howto or like, I will appreciate... I'm using the Conectiva Red Hat Linux (http://www.conectiva.com.br/ - a Red Hat 6.0 based distribution), and the PostgreSQL 6.4.2. I'm downloading the Zope 2.1.2 rpms. If someone is curious, I'm trying to do some kind of business to business app. I'm planning to use LDAP to help coordinate the users, groups and permissions. TIA, and sorry the bad english. -- Cesar A. K. Grossmann - AOLIM CesarAKG - ICQ# 53373705 http://members.xoom.com/ckant/ ...when you are obsessed with the enemy, you become the enemy.

Zope vs J2EE
by Nemeth Miklos 13 Jan '00

13 Jan '00

In our department I have decided (as a CTO) to use Zope for an ecommerce application server. And I also would like to use it for another application for a customer. I will have a presentation about Zope and our plans in a 3-day technical conference of our corporation. Can I have some (primarily technical) arguments why Zope is better to some (especially Java-based) specific web application server tool (WebSphere, Oracle Application Server, Oracle8i, NetDynamics, etc)? I'd be very glad if some of you share his thoughts about the topic. NM

When you have a collection of objects you want to iterate over, it is useful to put them in a container-like data structure, like a Folder. In your case, I think you can do everything you need by just placing all of your articles in a Folder. If the folder was called 'Articles' you could do very simple iterative manipulations using the <dtml-in> tag. <ul> <dtml-in Articles> <li><a href="<dtml-var absolute_url>"><dtml-var title_or_id></a><br> <dtml-var sequence-item size=200></li> </dtml-in> </ul> This will print a link to each article, showing 200 characters of the objects body (This assumes your article objects are DTML Documents). As an added hook point, you can write a DTML method that you pass the object to: <dtml-in Articles> <dtml-var "displayArticle(_['sequence-item'])"> </dtml-in> If you place Articles and displayArticle in your root folder, then they will be accessable from anywhere in your Zope, all objects in the root folder are acquireable from all objects in Zope (note, when you drop to python, you have to play by the rules of the Acquisition mechanism). > It is also a requirement of this site that it can > display previous editions of the web site.

Here the catalog can help you. If all of your article objects are cataloged in a ZCatalog object, then you can do a very fast range search over all of the objects' creation dates. This is used on the Zope site on the advanced search page when you pull down the combo box to do a range search of objects created after a certain fixed point in the past (day, week, month, year, ever). The problem is that as your articles change, you need to keep cataloging and recataloging them so that the catalog tracks any changes in the object. This is where things get tricky and you start developing an application, because you need your own kind of object to do that. This is when you should investigate ZClasses. There's a couple how-tos on the Zope site on how to make your own kind of catalog aware objects. In fact: http://www.zope.org/SiteIndex/search?date%3Adate=1969%2F12%2F31++16%3A00 %3A00+US%2FPacific&date_usage=range%3Amin&text_content=catalog+aware brings up about all of them (notice the 'date' and 'range' arguments to that URL? All objects created after 1969!). > Any tips on how I might structure my content (basically news > articles) and > how my presentation layer might be able to utilize the > content would be > appreciated. Make sure that all your major components are seperated from each other and use each other without strange dependencies (like assuming a path to a component, why assume when it can be acquired?). Keep collections of similar objects in folders by themselves. It is generally a good idea to keep methods related to certain types of objects in the same place as the folder that contains those objects. Use your root folder wisely, Luke. -Michel

Is there an API or function to get Zope/python to successfully pass large text fields or blobs through DB 2 API standard database?

Organizing Zope Content
by James W. Howe 13 Jan '00

13 Jan '00

I'm learning Zope in anticipation of using it on an upcoming project. The project involves development of a web site for a weekly news publication. I've been experimenting with trying to recreate a portion of an existing web site which offers similar functionality to what will be needed for my new project. I've started with taking some existing pages in HTML and refactoring them into various Zope DTML methods. I'm trying to restructure things so that content is separated from presentation. So far I think I've been somewhat successful in building up a presentation layer, but I'm still using some hardwired content in places. What I want to do next is set up a structure for the content which can then be plugged into the presentation objects. I'm looking for ideas on how to structure my content. For example, one of my pages needs to display headlines with little snippets of the article itself. Clicking the headline would cause the full article to display. What I want to be able to do is build a structure such that I could iterate over items, pick up headlines, and generate the headlines page dynamically. It is also a requirement of this site that it can display previous editions of the web site. For that I would like to be able to invoke my headlines in such a way that it could generate different headlines depending on which issue of the news publication was desired. Any tips on how I might structure my content (basically news articles) and how my presentation layer might be able to utilize the content would be appreciated. Thanks. James W.

---------- ## Forwarded Message ## ---------- Subject: [Python4linux] Something I forgot Date: Thu, 13 Jan 2000 15:04:17 +0100 From: Oliver Andrich <oli(a)rz-online.net> Hi, the mentioned web site is currently located in Germany on one of my servers. The connection is very good (1 34 MBit and 2 2 MBit lines), but I like to setup a mirror in the US too. Does anyone host a Zope server with SiteAccess and so on, so that he/she can host another domain on this machine?
