newbie questions about packages, external methods and persistence
by Gregor McEwan 02 Nov '99

02 Nov '99

Hi, I have 3 questions that are (hopefully) easy for someone with Zope experience. 1) What's the best way to access a python package from Zope? My current state of knowledge would suggest that an external method or set of external methods would be the best way. However, does that mean that for each external method that accesses one of the methods in my class, I have to create a new instance of the class? Is there some way to keep a reference to a class as a Zope object so that I can use it in different DTML documents in the same folder? 2) What are the issues with using ZODB filestore persistence in a package that is accessed through Zope? My package uses the filestore persistence and works fine when used by itself. When I try to access it through a web page using an external method I get an IO error saying that permission is denied on "Entity.fs.lock" ("Entity.fs" is the filename I specified to store the persistent objects). Do I have to use a different type of persistence? Or is there something else that I've done incorrectly? 3) There is an example of an application that seems to be very similar to what I want to do in the document "A Technical Introduction to Object Publishing with Zope". I realise that this document is dated but is the information in this example still valid? If not, could someone tell me, in general terms, what the new approach should be to this kind of problem? How does the Zope management interface fit into this? I realise that these are potentially big questions (especially the third), but I would be very grateful if someone could even just point me in the right direction or give a couple of hints :-) Thanks, ------------------------------------------------------------- Gregor McEwan Research Scientist DSTC Pty Ltd Level 7, GP South University of Queensland 4072, Australia Phone: +61 7 3365 4310 Fax: +61 7 3365 4311 Email: mcewan(a)dstc.edu.au "To know the road ahead Ask those coming back."

Altering product instance changes all instances!
by Edd Dumbill 02 Nov '99

02 Nov '99

Hi For my SiteSummary [1] product, I have a default image that is stored as a subobject in my ZClass. An instance of the product can upload a new image to replace it. Unfortunately that ends up replacing the image in _all_ instances of the product. This is not the desired behavior! Can anyone suggest what I'm doing wrong and how I might go about fixing this problem: ie. creating a distinct instance of the image for every product instance. Thanks Edd.

just another idea
by Clarence 02 Nov '99

02 Nov '99

Hello all! This may sound like a dumb idea for a product, but I believe that it has some uses for bringing more people to using Zope. This type of product would open up Zope to users who do not understand HTML but understand the point and click of a wysiwyg Word Processor/HTML editor. There is some software availible for this type of work, but it only runs on MS IIS/MS SQL Server (I do not know if there are any other aps which do this). Currently, it takes a Zope-master to create a Zope website. HTML gurus and SQL gurus can add to a Zope website, but what happens to organizations who don't have any of the above staff. They can't use Zope because it requires more skill than they will ever learn. (Yes non-computer users can create stuff with a wysiwyg editor and ftp the html into the ZODB, but someone has to create a website out of the objects.) The concept for this product involves giving non-computer people the ability to produce web pages kind of like a wysiwyg editor but with a web browser. Non-computer people need a web interface which will allow them to generate a basic web page similar to the way Zope allows a Zope-master to produce a complete website. In other words give them some point and click choices to do the following: (all items will need to be able to be aligned center, top, bottom, left or right) 1. input text 2. add image 3. add table 4. reposition pieces to a different place 5. add the above into a dtml method or document and allow the user to create links t this page from other pages (ex. index_html). This may sound like overkill for using Zope. Why don't these people just use IIS and Front Page. I believe that this could be useful for situations where one skilled user can manage a website, but not have to produce the entire website. An experienced user could create a website based off of the NavBar product (and others) and set up folders for the non-programmer users. These non-programmer users could generate their own areas that would acquire the standard theme of the entire website. This would be useful for schools or organizations who have multiple websites but not the staff to do the upkeep. Clarence T. Pate

Hallo, with the following code I set a new user with passord in the current folder but the role is always empty. The role exists in the folder. dtml-call"REQUEST.set('name','karii7')" dtml-call"REQUEST.set('password','npwd')" dtml-call"REQUEST.set('confirm','npwd')" dtml-call"REQUEST.set('roles:list','ExBenutzer')" dtml-call "acl_users.manage_users(submit='Add', REQUEST=REQUEST)" 1. what is wrong? 2. in which documentation I can find this?

You could lookk at the code for the FAQ; it shouldn't be too hard to figure out.

The FAQ and KB entries (and IIRC the Bases themselves) are GatalogAware, so you should be able to index them with a Catalog object, just as any other. 2.0 will have some of this integrated better. > As far as Ideas go.

The problem with doing a tree is that it would be basically useless in a site that standard_html_header used a tree tag, since you can (AFAIK) still only have one tree per page. Otherwise, A tree would be cool to have. Thanks for the suggestions, I continue to work on The KnowledgeKit, and appreciate them.

zope powered
by kedai 02 Nov '99

02 Nov '99

hi all not sure whether this request is top priority or not, but .. i think we may need a more attractive zope powered icon(s). like the gimp, they got wilbur, apache, the feather, red hat, the red hat (of course). what about zope? IMO, the current zope powered graphics is a bit bland. how about a lightning flash that is shaped as Z? lightning is fast, it's electrifying, it's pure power; which is what zope is. comments? suggestions? flame (;))
