I work with zope over a 56K modem (really about 38K) all the time.

Re: [Zope] Transactions support on MySql

>> How can I do database transaction controls(set autocommit on/off, commit >> transaction, etc) myself? > > A correctly written DA will start a transaction when the database is first This is important to note. All DAs must support the transaction semantics, regardless of whether the underlying RDBMS support transactions. You should *never* under any circumstances try and modify the style in which transactions are committed at the Zope level. The choices are made for very specific and conscious reasons, and changing it could cause catastrophic corruption of data :-) (that's a bit of an overstatement, but don't do it).

ObjectManager-derived ZClasses problem
by Petru Paler 27 Sep '99

27 Sep '99

Hello all, This might have been asked before (but the mailman archives are gone): I have a problem with ObjectManager-derived ZClasses. Scenario (using names from the ZClass tutorial): create a ZClass named CDCollection derived from ObjectManager, and inside that create a ZClass named CD. Now add a CDCollection. If you try to add a CD inside that, you get a not-so-nice "Resource not found" error (traceback included). Any ideeas ? overly-confused-ly yours, -Petru

Questions about Zope strategy
by Alexandre Ratti 27 Sep '99

27 Sep '99

Hello, I just discovered Zope and I'm impressed with its potential. I am considering using Zope to create and manage a Web site for a smaller French human rights organization. You'll find below questions about Zope "strategy". I went over much of the Zope docs; now I'd like to have feedback from experienced Zope users so that I can build a strong case. - Context Creating and feeding the site will largely be carried out by voluntary workers (many Mac users, also Windows users). The site would probably run with Apache on a Linux box at a provider. Content creation for the site is almost finished. The site will contain about 400 HTML pages. It will be fairly text-intensive. We use a preprocessor; this would make it easier to prepare the pages when moving to Zope. - Setup This organization doesn't have a permanent Internet access. Site creation will be carried out locally on an NT box. However, site management and text update would need to be carried out over dial-up connections (33600 bps modem; 64000 ISDN connections at best) when the site is online. => Do you feel that the slow access could be a major problem? I'd expect people to enter smaller text changes online. When adding pages I think they could create the pages with a Wysiwyg editor (eg. DreamWeaver) and import them into the database later. I'd need to find some way to add the header and footer markers (in a template in the editor, maybe). When updating the pages they could export them to HTML, modify them locally and reimport them into the database later using Upload. => Is this OK? AFAIK it's not possible to export to HTML an existing page content without rendering it. I guess I'd need to create a Python script. - General database maintenance could be carried out by a couple of "techies" in the organization. However, text changes may also be carried out by people with little or no previous experience in HTML coding. We would train them but I'd like to keep things as simple as possible. In some cases I may use forms to guide text entry. - XML question: I've seen that add-on products are available to import XML into the database. Is it possible to store an XML file into a single document file and to render it to HTML? I suppose Python scripts are needed. - We may add other features later such as a restricted members area and a database link. That's it. If you see any glaring misconceptions I'd be really glad to hear about them. Thanks for your time. Alexandre

IE file upload problems
by Rik Hoekstra 27 Sep '99

27 Sep '99

We are building a system in which users can upload all sorts of files to a zope database; they do not have access to the management screens. Nothing spectacular so far. Now it appears that in _some_ installations of Internet Explorer (but not all) for whatever reason uploaded files are stripped of their extension, so that foo.doc becomes foo. to Zope. This makes the documents end up with a content type property of apllication/octet-stream (or something alike) and clicking on the document prompts for a download instead of opening a word viewer. SOme questions: - has anyone seen this before - what is causing this - how it can be solved (other than not using IE) I know there are ways to hack around this, but they are all either clumsy or complicated.

While we're on the subject of pdf - does anyone know about (python) tools to extract information from a pdf document apart from ps2text (so that they become searchable from within ZCatalog, and I do not have take resort to MS IndexServer, which is less than comfortable)?

Force "login"/authentication?
by Steen Suder 27 Sep '99

27 Sep '99

I'd like to have a button on my in my site where managers can login and, thus, get out of the anonymous role. The link shall not have <a href="manage"> in it. It shall just popup a login box (like entering manage), gets you authenticated and then leave you on the page you came from. Is there a DTML function that do this? -- Best regards / Mvh., Steen Suder Linux Systems Administrator Use "sfs @T sciatl DOD dk" for email
