Where would the object aquire its attributes from? Would it try one of its folders, then the other? Which order would it choose?

ZClasses gripe
by Andy McKay 17 Jul '00

17 Jul '00

I hate to do something in ZClasses, but I did today just because I didnt have the energy to write in Python. Oh how I wish I had. It was all so simple except for "DestinationURL" not being implemented or being used patchily. It would be really great if we were able to write our own destination once a form has been filled. This would give us much better access to things like property manager. Oh well back to Python. -- Andy McKay, Developer, ActiveState http://www.ActiveState.com Programming for the People

Because it's object names instead of paths in the request, how do > you send optional, additional info through the request as above? You've answered your own question. There is no end in the middle of the path. The publisher picks off each part of the URL from the top down, and at each step, it asks that object if it can provide the next one. Look at traverse() in lib/python/ZPublisher/BaseRequest.py, or step through the publishing process - see <http://www.zope.org/Members/michel/HowTos/TheDebuggerIsYourFriend>. At each step, the publisher checks to see if the parent has the child as an attribute, and if so, continues with the object at that attribute as the parent (so long as other conditions are met, like permissions). You can see this in python products: class Foo: "a python product" ... index_html = HTMLFile("someDTMLFile", globals()) index2_html = "<HEAD><BODY>..." index3_html = aFunction(mood, phaseOfMoon) Since getattr(path.to.foo, "index_html") reaches that html file, ZPublisher.Zope("/path/to/foo/index_html") publishes that file. index_html could be a (badly named) method instead, which has other attributes. It could decide what to publish or how to allow the publisher to traverse the path programmatically. You don't need extra rules that look for foo.pl in the URL (what a kluge - enforce a perl script to sit there until URLs are no more!). For your example, script.pl could have two subobjects or other attributes, 1234 and 2345, and the default index_html. Or script.pl could be a ZClass with those three as DTML methods or other subobjects. __bobo_traverse__ is another attribute that the object may have to drive the publishing process, but I haven't needed to understand why it's useful yet :) -- Karl Anderson karl(a)digicool.com

Is there anything wrong with the method or is there something other to look at? Ciao, Jochen

Printing data from a external python method.
by jesse 17 Jul '00

17 Jul '00

Hello, I'm creating a smart forms type product, similar to Smarter Forms. However, smarter forms, while a good product, is not as user friendly or as smooth running as we would like. What I am doing is creating a Index, which calls the form, which once completed posts to the external pythod method formchecker. However, once formchecker checks to see that all the fields were filled out, how can I use the EPM (external python method to print out the data on a dtml method? Thank you for your input, Jesse.

I have created an __init__.py which registers MetaEntry objects properly but uses MetaPublisher's constructors. This means, if you select a MetaEntry to add to some Folder, you will actually add a MetaPublisher. This might not be the cleanest solution but it works :) I attached a sample __init__.py file, which you should copy to 'lib/python/Products/MetaPublisher'. > then the next problem was that when i used the getpath directive to get a > url for the records returned by the Catalog i got a url like this > mpfolder/mp_entries/9995757.435 which plays all kinds of havoc with my > carefully crafted directory structure ;-| depends on your structure... what exactly is the problem? unfortunately, in the current version, the mp_entries folder has to stay. there are early plans to remove it completely but this will take some time before it becomes a reality. > any ideas? some... ;) > Regards, > GEORGE DONNELLY > george(a)cyklotron.com > http://cyklotron.com/ > The smallest minority on earth is the individual.
