[Zope] Reading ZClass properties from outside the ZClass
I have a ZClass, "MyZClass" which contains 2 propertysheets, "PublicInfo" and "PrivateInfo". PublicInfo contains Selections produced from Lists in PrivateInfo. Works wonderfully, however in the site I wish to get at the PrivateInfo items without touching an Instance of MyZClass (Its easy that way but I cannot be sure that instance will always be there). Basically I need to do something like... This works when logged in as an Administrator as the Control_Panel is visible then, however for normal users it fails. Is there a way to get at these details without asking an instance? I'm assuming that the answer is no due to the security aspect but it would be preferable in this case to have the List in the ZClass rather than in the site content (perhaps in the root folder properties). I've suppose I could use a Proxy role but I wonder if there is something as simple as.. without doing Phill ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
[Zope] On DTML and Python Script
Jason Leach pointed out that Document Template could include ASP/PHP style Python escapes to embed code. This may seem a good idea at first but part of the really nice thing about Zope is that it goes a fair way to ensure you organise your work cleanly and seperate logic from the layout. In PHP I always use FastTemplate which offers pretty much only what does (that doesn't include or anything "clever"). The benefit of having no logic in your HTML is huge when you have multiple people working on the project. The "creep" of template systems to hold more and more logic such as Loops, Conditions etc is forgivable as it allows basic programming to be done by the HTML people but strictly it isn't necessary as long a variable insertion / tag replacement is possible. If you are "having to [use] all those dtml tags" then you're probably at the point where replacing that big chunk with is in order. This could be anything you want (Python method, External Method, DTML method etc) which does the real logic and conditionally returns its output to the master template (that content possibly from another smaller, reused DTML method - it amazing how many sites use the same text all over it (like Next 10, Prev 10 for example!). At that point you've removed any fear of the HTML people walking over your code with a bulldozer and it means they can update things while you do. What I'm suggesting is that <%, , and tags could be argued to be Bad Things but they are convenient in some cases (they are easy for HTML writers to understand and can be used for simple things by them). I don't really see the "convenience" of a Python code escape as its just as easy to make a Python Method and pop in its place keeping things neat. Still, I suppose it'd hardly matter if it was available, those who agree with the above would probably ignore it, much as I ignore it in PHP and use FastTemplate instead.

[Zope] GPL stuff (OT)
Zopistas, I've heard a lot of GPL issued raised recently and I want to say a couple of things to hopefully end the subject. I don't mind you pointing replies to me if they aren't of general interest [hint ;)] Firstly, read the GPL. It sounds like some of you talking about it haven't (or have forgotten its contents). That'll clear most things up. Its ambiguousity is limited to very technical cases such as dynamic linking etc. Even in that case, the use of the GPL'd C Header files at compile time can be taken to be indication of agreement to the GPL (even the use of header files produces a legally defined "derivative work" - one look at the sql.h files MS distibute to make that clear. The lack of court testing is irrelevent too, that hasn't happened becuase no one has stood to gain from it - a good indication that they'd lose. If any company found real legal fault with the GPL where they could take code and not be force to comply, they would have done. The legal issues surround very specfic cases, not the entire license. The Objective C front end to GCC is there because NeXT backed down after admitting a futile case. The "its not been tested in court" argument applies for many many licenses and EULAs but you can bet that the flip side is true also - the reason its not got to court is becuase everyone seems to be agreeing to it out of court - a precedent no court would ignore if it ever came to it. The compatibility issues of [MQZ]PL / GPL are generally cases where some case is strongly demanded which the GPL strongly rejects. Things like choice of law, the right to take patches for non Free use etc would cause incompatibility due to the difference in the rights assigned to the user under GPL and those not allowed under the other. This DOESN'T stop you using the GPL in Zope though if you specifically allow it on your side and the creators also do. As far as I know, DC hasn't forbade modules under GPL to be used, or rather they have made the Product interface "open" enough to allow even proprietry Products to be written and used. Of course, this is module authoring (even Linux kernel modules need not be under GPL). In the case of taking ObjectManager.py and adding things to it, that stays under ZPL like it or not (even your changes). That is where the two are incompatible. You can take embed GPL code in BSD code - that's why they are "compatible". To call that "pilfering" but not mention companies who take BSD code and don't even share their extenstions is a little harsh I think (the windows FTP command comes to mind). I don't think that using a GPLd product in Zope (via the Product interface) would mean you have to give source away for _your_ Products and site code which uses them. They are distinct and bound only by the open interface Zope provides. If, however, you change the GPL'd Product, then you will have to stick with the GPL. Either that or re-implement. And yes, you will have to offer the GPL'd parts under the GPL terms if you distribute the whole. A real world case of this? There are many commercial products that include GPL code. I've seen it used in firewalls and printers and in all cases the GPL parts where distibuted under GPL of course. The distinct parts (non linked, seperated by "open interface" - be that as seperate processes, kernel modules etc) are not always available under GPL. Philips' Tivo site has their changes to Linux under GPL available. You won't find their MPEG suite though - shame ;) The GPL has no direct stance on making money or otherwise. You can sell GPL'd code for all you like, changes or none. It only governs the rights assigned to those YOU distribute it to (not the world). However, that one customer then has the right to distribute to the world. Unless you are bloody good with your support and documentation, they won't need you. If you are good that's a different matter. The choice of license on an open project isn't, from the real world, an indication of how well it'll do commercially either. Yes, apache, XFree86, Perl, Python etc etc all use non GPL licenses and that's good for them in some cases - their aims are DIFFERENT to FSF/GNUs. Besides, Linux, GNOME and the GNU compiler tools get just the same amount of commercial recognition (Mozilla is now also under GPL), if not more and from just the same people. That's about it. The only really clarifcation needed to clear this all up is... 1) DC to say Products do not have to be under ZPL and to deem their Product API an open interface akin to Linus' statement on the Linux kernel module interface or RMS's on calling GPL'd apps through the System() call. 2) Any GPL code that effects Zope's core will have to be deemed under ZPL while running with Zope. I'm not sure any Products do this but in the case of any, this would sort it out. Yes, its really just a dual licensing scheme but many do that - Mozilla, Perl and Qt amongst them (and all with the GPL alongside their other license). In the case of the first b
[Zope] ODBC Bridge / SQL Server stuff
Hello, Easysoft (www.easysoft.com) supply a simple, efficient SQL bridge which works well with unixODBC (.org) and iodbc (.org) driver managers. We use it on one of our PHP sites to link to an SQL Server db from Linux. It works fine but its a close product. So given the easy of use of XML-RPC or SOAP from Python, it may be sufficient to create your own bridge which calls a remote DB connection made with ASP or Zope on NT. I've set this up with a Python method calling a remote DB connection in PHP using XML-RPC (just pass the query over and get the records back) and it works perfectly. Hope this helps.

Re: [Zope] ColdFusion->Zope converter
John Leach wrote: > > Anyone have one of these ? > (or tips on writing such a thing?) > John Leach > http://www.bosware.com.au Ouch. As far as I know CF has a few hundred tags available. Zope/DTML offers only about 10-20 but provides the same underlying features in Python via the expr="" attribute. You'd really be looking to transfer CF to python. This would probably produce code that sucked under Zope as CF doesn't offer as many core platform features like ZClasses, Aquisition etc. I'd say the best conversion tool is simply someone who knows a bit of both (or a bit of CF and a sizable chunk of Zope). I can only imagine CF->Zope convertors which would leave you wanting to rewrite the resultant code anyway. That said, it could at least offer a neater way to import your CF files into Zope but import and FTP already offer that.

Re: [Zope] Is Zope slow?

Of course, they do not provide all the features of Zope, but >they are able to handle things like sessions, authentication, database API...which is >quite adequate for most small-to-medium websites. (although sometimes it's quite >frustrating putting the modules together:) Yes, Zope is slower than Apache but so is a bus compared to a porsche. However, you can do things with buses that would take forever with a sports car, and some that are impossible (moving furniture ;) If you want the best of both worlds, map out the images and large static files from apache's config to go to itself and forward the rest over PCGI to Zope (read up on mod_rewrite). This way, the dynamic stuff is served by zope and the static stuff is handled by apache, both doing what they are good at. You can add LocalFS to Zope to allow administration of the static files too. This is what PHP does, that is just a module which handles php files, everything else is handled by Apache. PHP itself isn't that fast (it doesn't even cache compiled code). A decent 500Mhz PIII will knock out about 80 pages per second under Zope (~40 for complex things) but given that many sites where speed is important are very graphical, the ratio of a zope hit to an apache one is reasonable - on the site I'm working on this is about 1:10 and current traffic (not yet under Zope) is 18Million hits per month. If ever you run out of power (or reach the halfway point) you can start thinking of adding some caching or migrate to ZEO. In fact, if that happens, you'd be stupid not to have some sort of cluster - you'd have a very busy site!

[Zope] Post method redirection / Core changes
Hello all, We recently had a "sales engineer" from Allaire come and talk to us about Spectra and were quite surprised at how similar it is to Zope. To be honest the only thing I left with any "ooh, thats neat" feeling about was their general style of building objects with the admin view optionally identical to the user view but with icons inserted below images, content etc to allow immediate altering of the content. The same stuff is simple to acheive in Zope, almost. Make a ZClass, add index_html which adds a header, footer and puts render_html in the middle. Then use render_html to embed it in other docs and index_html to view it standalone. Add a check to see if the user is logged in and has View management screens rights, if so give them little icons "in place" to edit the content and images. This works fine.. Now, this part is simple enough but it leads to a problem. The default methods for updating ZClass properties and images all redirect back to manage_main by the look of things. I propose that two things be added to this to allow simple management of redirection from the update/edit/change methods. 1) All instances of manage_main be changed to manage_workspace so the default view if given rather then contents_html. 2) That an optional redirect url can be supplied to everywhere this happens to override the redirect. Then once a user logs into the site, leaves the admin view after perhaps joining a version and travels through the site, it has extra icons immediately allowing them to edit the contents of certain things. The redirection would take them back to the extended user side view after pressing submit. I've looked at Image.py in OFS and this is fairly simple but I thought I'd suggest it so we could perhaps form some standard on the redirect url variable that would be passed about. Any thoughts? Phill ps. I've not looked at the DestinationURL stuff properly to see if it does anything like I'm asking. ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

To speed things up, the limit 1000 appended to the query to stop MySQL giving Zope lots of lines when it only wants 1000 anyway. Its not too clever though. There should maybe be a check to see if "limit x" exists in the query.
