Design data-storage / search
by Antwan Reijnen 25 Mar '02

25 Mar '02

Hi all, I have a design question. I'm using the CMF, but my questions are not specific for CMF, so I post it in this generic group. I want to construct a CMF content object, which contains a questionary of about 50 questions. Some require a free-text answer, others are multiple-response- or singe-response answers. Sometimes a combination is used ("please enter your motiviation here"). The answers of this questionary should be searchable. The standard way (?) that comes to my mind is to construct a portal_catalog with a rather large index of more than 50 keys. But I'm wondering if this is the optimal solution for this kind of data. Should I use a database or another kind of datastorage for these kind of data-structures? Tinytables? Maybe I should construct a special catalog for this, so the portal_catalog does not become inefficient? Any thoughts and experience on this kind of subject is highly appreciated. Thanks in advance, greetings, Antwan.

How to upload files and create file objects from DTML page?
by Mark Spencer 25 Mar '02

25 Mar '02

I want to have a normal DTML page for users that allows them to upload and download files (without needing to use the management interface). The downloading and display of files is fine, but I cant figure out the zope/python code to create a new file object and store an uploaded file. The files could be upto ~60MB in size, and can be zip or doc files etc. Has anyone seen suitable sample code for this?

approach for persistent global links - is this good?
by Jens Wolk 25 Mar '02

25 Mar '02

Salut everybody, in a yellow pages ("zyp") product I need pointers or links between objects. For example I have categories and links to categories. It is necessary, that such a link to a category is still valid after having moved the category; this is why storing away the path isn't applicable. As of now, Zope doesn't provide a global id one can work with. (For a discussion about this issue and possible solutions in the future, see http://dev.zope.org/Wikis/DevSite/Proposals/ObjectHub ) I found a solution which seems to work fine for me: each category gets an attribute called "zid". This zid is globally unique. (Based on a mechanism presented by alex.khan http://dev.zope.org/Members/alex.khan/GlobalSystemId ) Storing a link is as easy as storing the zid of the linked category. However, the lookup of a linked category is done by a lookup in a ZCatalog with an appropriate field index. What do you think about this? This might not be such a good idea in terms of performance. Your comments are very welcome Jens Wolk

Unique object Ids
by Tom Cameron 25 Mar '02

25 Mar '02

When I try to render an object I often get something like '<Model instance at 02620E00>' This suggests to me that this object has some kind of unique ID 02620E00 that identifies this particular instance. Is there any way that I can query an object to find this id? My aim is to find some way to uniquely identify all objects so that I can find them later without having to store their entire path. Tom

Security and document library product
by D.Turpie＠open.ac.uk 25 Mar '02

25 Mar '02

Hi there I am currently implementing the document library product on Zope/CMF and have a security question. I have a number of different types of users who should have differing access to the Document Library. There are anonymous users, content authors and content managers. I would want anyone (anonymous or otherwise) to be able to look at, search and browse the library and I have achieved this. I would want the authors to also be able to submit documents and this I can also get working At a third level I would like content managers to be able to review submitted documents but can't seem to implement this level of security. I have followed the Document Library documentation and set-up the security as it says but this still doesn't seem to give content managers the right to review. Probably something I am or am not doing. Any help, ideas gratefully received. Thanks. David.

Should we really be seen as a bunch of spammers?

Hi Pete, Peter Sokolowski wrote: > > Chris I apologise for trying to offer you a system that can be of benefit to > you and your company, but obviously you can not see the benefit of this. I can see the benefits, I can't, however, understand your marketing tactics. I've been well aware of Bizar software for some time and had been considering your product for a project. So, you didn't need to send me a lump of HTML spam to try and ease money out of my pocket. It's degrading, you take what for all I know could have been a first class product and lower it to the level of a cheap porn site by your method of advertising. > To let you know our product is very extensively used in the ZOPE community > and will be by The Zope Corporation them selves. They see the merits and > benefits of the product and fully support and endorse it. They helped a > great deal with the developments and OZ-Zope have even built their own store > with it. That's good news :-) I'm sure a case study on zope.org or information on your site could have told me that when I went looking. I'm fairly sure you didn't actually include that information in your spam, which is strange. > I don't know what exactly has ticked you off, obviously you were > having a bad day. Well, let me be entirely explicit. I have an extreme aversion to unsolicited marketing communications such as junk mail, coldcalling and spam, especially when they are damaging to the industry which currently forms my primary revenue stream. As a form of marketing, spam simply doesn't work and as a national account manager, I'm sure you know that reputation and referal will get you a lot further in most cases. > Probably because your company is going under you refuse > to look at any system using your beloved ZOPE to help you increase profits. Quite the opposite. Zope is at a big crossroads right now. We have Zope 3 in development and a backing company whose stated aim is to grow Zope 10x over the next year. It can go one of two ways; if we can all work together with integrity I reckon we can make Zope into a world class product and very lucrative market. If we let ourselves cheapen what is currently a shining light in the open source world then it may end up being just another crappy little system that people are forever trying to replace or ignore completely. > I have no problem being told to fuck-off but your attitude sucks and you > should get a life. I am more than happy with my life, thankyou ;-) As for my attitude, yes, it is a problem since I really should stop handing out free business advise to competitors :-( > I will also post your response email to the zope mailing > list, so that people can see first had what a wanker you are and I will make > sure I also on send your response to Zope Corp them selves. Well, I see you chose to back down on that so I thought I'd do it for you :-) > You were given the option to unsubscribe from our list, Now that's the kind of thing that REALLY pisses me off. Why should I have to do ANYTHING to stop recieving junk email? I certainly didn't ask for it, why should I have to ask for it to stop?! <more abuse from Pete snipped> > I would be happy to continue this conversation over the phone, but I am sure > that to are too gutless to go down that path, as you feel safe protected by > your computer screen. Well, were I in Australia I would happily continue it face to face ;-) As for the phone call, I would, but to be entirely honest, I'm not going to spend the cost of an international phone call in providing you with free consulting on how best to market your product. Should you be interested in some consulting, do get in touch, I'm sure we can arrange something :-) cheers, Chris PS: If anyone is interesting in either the initial piece of spam or my response to it, please let me know and I'll forward them off list...

Problem displaying products icons with virtualhostmonster
by Joachim Schmitz 25 Mar '02

25 Mar '02

Hi, product icons are displayed in the management-view with a tag like: <img src="/Control_Panel/Products/MyProduct/MyFolder/ziconImage alt="MyFolder" title="MyFolder" border="0" /> If I do virtualhosting with VHM, I have no access to the /Control_Panel, and I don't want to grant it. Zope Icons are accessed like this: <img src="/misc_/OFSP/Folder_icon.gif" alt="Folder" title="Folder" border="0" /> where I can grant access to the "/misc_" folder. Any suggestions to solve this ?
