Please have a look at the "Hookable PUT" proposal (which has already been implemented for 2.3): http://dev.zope.org/Wikis/Proposals/HookablePUTCreation This project adds an API to the handler for HTTP/FTP PUT requests to non-existent objects (so that you can specify/tweak the object which is created). Handling PUT in the object directly (for WebDAV/FTP/HTTP "uploads") would be the job of your File-like object. The PTK's content objects do this now, for limited types of content (structured text with RFC822-style headers for the metadata); we plan to add other filters there, as well. We'd be glad of your help definining the API. Could you take the text of your message and create a "fishbowl" proposal with it on the dev.zope.org site?

Creating a Database connection.
by Darren Carney 05 Jan '01

05 Jan '01

Dear Zope, I am very new to the Zope idea. I like what Zope is trying to do. But I am trying to set up an external SQL database connection. I have read the information thats on the Zope website. It has not made it any clearer about setting up a DA and making the connection. Thanks in advance for any help that you would be able to supply. King regards Darren

How to call ancestral method in ZClass method?
by Dirksen 05 Jan '01

05 Jan '01

I have a ZClass 'stuff' which is a subclass of DataSkin. 'stuff' overrides 'manage_delete' method, so as to do some extra clean-up jobs. After that, it will call its ancestor's 'manage_delete' method to wipe itself off. In java, you can do this by calling 'super.manage_delete()', but how to do it in zope?

Re: [Zope] Core Session Tracking kudos & namespaces

I've only been looking at zope for a few weeks. I DO have a significant application that handles a customer database, supplier ordering, inventory management and the like. This is currently written in Perl/cgi, and is way too slow and cumbersome. I'd like to move it into zope and at the same time make the database directly available to customers. In the current implementation of the application I maintain a lot of state at the server side--the server knows the page history, locally configured options, and the like. In that application I actually force you to use server-side navigation, since I load over the existing page every time you make a request (so there is only one page ever resident in the browser). I did this to make it impossible for the operator to use an old browser page (with stale form info). This is ugly and requires two round-trips for each request. I'm trying to figure out how to move this into zope, and to do this in the most natural way possible. So I'd like to give up mostly on the server-side navigation stuff. But I do want to do things like: if you go from a main page to a form, then if the form succeeds I'd like to return you directly to the main page (with no extra page fetch). If the form fails, it might go back to the main page, or include the error somewhere in the main page. Since the form is likely to be unrelated to the main page (just linked to from it), I need at least some server state to tell me where to return. I can also imagine doing side trips from forms--but that's harder, because then the side trip can't involve a link, otherwise you lose the information typed in (I "solved" this in my current implementation by wrapping *every* page in one big form and making all the links actually do submits, using a little javascript, but again that's something I'd rather avoid--I'd rather it was simple and relatively unsurprising). I'm unclear as to how I should really implement any of this. It almost seems like there is some sort of abstraction here that can be turned into a generic facility, but I haven't groked zope enough to figure out how that would be plugged in and what it would look like. So anyway, this was supposed to be an answer to your question, but it's really a thinly disguised attempt to get some design help on this. Is there another forum purely for design help with this sort of thing? How to fit a particular navigational abstraction into the zope framework?

case insensitive search?
by Robin Becker 04 Jan '01

04 Jan '01

Is there an easy way to make the Find tab case insensitive. It seems like a very common need, but I see that FindSupport.py is calling string.find which makes it seem as though this is harder than it should be. -- Robin Becker

Re: [Zope] Zope eating CPU/RAM - how do I find the culprit?

First, I meant double quotes (") not single one's ('), in case that wasn't clear. I know that for mysql, postgres, oracle there are column names which will surely break dtml-sqltest as it is implemented now. Either lowercase letters (oracle, as you also noted) or uppercase (the other two). I guess sql-keywords and special characters as column names - ok, not a very clever idea - will break sqltest on all of them. At least I didn't find a way to get it to work without patching zope. Searching the web I find various hints that many odbc,jdbc adapters and sql-db frontends use quoted names per default (psql). Unfortunately I don't want to pay to the ANSI-commitee for reading into the sql-standard, but I'm pretty sure every newer database supports that. > Even if it does, the proposed change will probably break > lots of existing code. Right, how about adding a argument like, let's say "sql_quote"? ;) Unfortunatly, I fear I'm have not enough knowledge in zope's internals to offer a clean patch. > I fear, in our projects, the fact that case does not matter > has been widely used. > We would have to change hundreds of SQL methods > after the proposed change. > For new projects, I would like to have it your way. > However, this will be difficult to achieve. I would like to see quoting as a standard, but you have a point. Maybe sql_quote is the way to go. cheers, oliver
