[Zope-dev] RE: RFC : ZPatterns Customer Relationship Management Framework
Thanks for your comments on our model Philip, it is really appreciated and very enlightening. From your comments some other questions came to mind (I posted this on the Wiki as well): It seems that we did not give enough consideration for the pattern, Roles Before Objects but we can retrofit this pattern to our existing design without to much trouble. The area where I need more guidance is on the ability of a specialist to add attributes on top of objects. Thinking out load: Objects might have different attributes depending on the roles they play in various application frameworks. Specialists make it possible to add these attributes through AttributeProviders. One might create a Person ZClass with properties Name, Surname, Age. When the Person plays the role of Customer we will create a Customers specialist for that role providing us with services relevant to dealing with Customers. Let's say for now that the properties defined on our ZClass propertysheet for Person suffices for the Customer role. Our Person object also plays the role of Requester in our Requesters specialist. For this role we need an extra attribute, Priority. The Requesters specialist will ask the Customers specialist for properties Name, Surname and Age but will store the attribute Priority in it's own rack. For storage in the ZODB this will imply that the extra attributes will be stored persisently in the slots of the Requester. For non-ZODB storage like a SQL RDB one will have to add a table to the RDB.

Re: [Zope-dev] PythonMethods: Can't Slice context.REQUEST.PARENTS
Okay, I figured that bit of braindeadness out (I just use a range that goes backwards, no .reverse() so everything is left as is. Now here is my next problem. Using context.REQUEST.PARENTS doesn't give me the DTML Document that called me (so to speak). I have: /test/new/foo_html My PARENTS shows Zope, Test, and New, but doesn't show foo_html. Is this because my PythonMethod is Internal vs. External? I didn't see any descriptions of what the differences are. The DTML Method version of my code can see the id/title of the foo_html via 'id', 'title' and 'title_or_id', but under python I just get: self.title_or_id() -- Zope, the folder that my method lives at m_self.title_or_id() -- Breadcrumbs (my method) context.title_or_id() -- New, the folder foo_html lives at And I have no idea what _ is for Any help is appreciated.

Re: [Zope] images in directories
I have a similar situation where I find myself way down in the tree
structure and have to go up to a certain point and down again. Leaving "bad
structuring" aside (actually its well structured in many other respects),
all I could think of to get a hold of these objects was a whole bunch of
nested "with" statements. They suck.
Now what's with your PathHandler product? How would an appropriate method
look like? I was thinking of a "walk2object" method rather than
"showImage"... see I don't want to start at "/", I want to start whereever I
like at that moment and still take the "/"-separated path info to "walk" to
my object.
I think this has more to do with elegance than with lazyness. (tho these two
know each other very well ;-) )

Anyway, if you're _really_ lazy, write an external method something
alogn the lines of:
def showImage(self,path):
return self.restrictedTraverse(path)(self,self.REQUEST)
...then, in your dtml, you can do:
dtml-var "showImage('/images/image.gif')"
This is all totally untested of course ;-)
I've often wondered why this isn't built into DTML so that you could do:
dtml-var /folder/myobject
obviously, you wouldn't be able to do this with stuf inside " " ;-)

Maybe, "get_page_title" is callable. In this case, e.g.,
"dtml-get_page_title;" is very different from "get_page_title".
Try to replace "get_page_title" by "_['get_page_title']" at
both places in your code.

Re: [Zope] Can Zope use a Different Python?
Hi i'm not sure exactly whats being asked here. zope on linux doesn't include its own python interpreter. you can choose which one executes zope and its external methods by specifing the interpreter binary in the start.py. its quite possible that your installing third party modules into the distros python in /usr/bin/python, in which case if zope's using /usr/local/bin/python you won't see them and you'll get import errors. if this is the case copying the third party modules into /usr/lib/python1.5/site-packages will solve the import errors, or moving the modules into the zope_dir/lib/python/ (or perhaps a subdirectory with an init) might do the trick. if you specifically want to run something through a custom python interp from zope you might need to use os.popen2 (or variant) in an external method, or setup sometype of interprocess communication via xml-rpc or an rdbms or shared file, etc. hope that helps kapil Gary Perez wrote: Hi.

[Zope] LDAP variable problem 'title'
Hi Zopistas, Firstly, a big thank you to all thos epeople who helped me with KeyError problem when accessing LDAP entries. Just so the solution makes it onto the mailing list archive (for the next bunny who has the same problem) the solution was to add the following to each of your variables missing=nbsp; ...so that when Zope came across entries without that attribute it didn't barf. I now have one last problem. I can now access all entries from the LDAP directory using the notation dtml-var sn missing = nbsp;- all except one - the "title" attibute . I am guessing that it is because Zope uses "title" to reference the title of the object in the zope database, and therefore won't let you get at the ldap variable using the normal: dtml-var title notation. Is there any way I can pinpoint the LDAP variable instead of the object title in zope? I have no control over the ldap server and attributes name, so I can't change it at that end. When I test the LDAP filter method I can see the variable (it lists all of the attributes of the LDAP record), but I can't reference it in DTML. My filter method is called 'Academics' and just extracts a list of academics in the biology department here at Monash University. I'm sure there must be a way using python notation, but not being a python expert (yet!), I could do with a few clues... Any ideas?
