[Zope-dev] ZPatterns example update....
Hi Folks, The Dumb ZPatterns example is updated. Now there is some more realistic object referencing going on, borrowing of code snippets between Specialists and suchlike. There is also more in the way of reasonable documentation, though everything is in flux, and it still doesn't resemble a truly completed product. I just feel the need to get things finished enough that I can stop thinking about them for a while. ;-) In particular there the ToDos now hold references to Doer and Deliverable, and no 'lists' are maintained. One thing I need to do is to have these references automatically 'fixed' when a 'referred to' entity is removed or modified in such a way that the link should be broken that's for the next version. If I'm not careful.. it won't be a 'simple' example anymore. There's got to be a line here somewhere (in the sand?). take care, -steve ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
Re: [Zope-dev] ZPatterns question
Hi Christian, Well, nobody else answered that I saw... so I'll take a crack at your questions "CS" == Christian Scholz [EMAIL PROTECTED] writes: CS Hi there! CS Finally I managed to get a basic understanding of how to do CS things with ZPatterns ;-) So seems quite cool :) (and CS hopefully I find some time to write some basic howto about it) CS But I have some little questions: CS 1. Is it possible to retrieve the set of known IDs from a CS specialist? Or would I need to add my own method to it which CS does this (and change it accordingly if I switch to another CS storage method)? If you store persistently you can use the Rack's method: "defaultRack.getPersistentItemIDs()" but a couple of notes: 1) this returns a BTree object, not a simple list, so you can't iterate through it in DTML. You'll need to copy it to a simple list for that.. and 2) If you change to a different storage you'll need to create your own method (ZSQL Method?). What I've found is that if you have a large number of objects you'll either want to query a Catalog, or an SQL database to get Ids that match some criteria that limit the number of hits to something that makes sense to display in a browser. CS 2. Is it planned to provide something like a virtual folder CS which acts like a normal object manager but is controlled via CS ZPatterns (so actually something like Folder with Customizer CS Support just without the "anchor" in ZODB. (would also CS require some mechanism asked for in 1.) Hmmm... I'm not sure what you're after here. Why not just use a Specialist? In what sense do you want it to be virtual? (Are you looking for a dynamic traversal interface that would allow you to map URLs to objects that are managed by ZPatterns? Can you give an example?) CS 3. Is it possible to use ZPatterns also without some exta CS ZClass defined in a Product? At least if I don't need methods CS for my objects but simple want to define the attribute they CS know. Would be nice as I could then hold everything together CS in one place (the specialist that is) without requiring to CS install something also in the Products folder of the Control CS Panel. I believe you need to either create a Python subclass, or a ZClass subclass of DataSkin. "Raw" DataSkins don't have the right permissions to allow for TTW access. If you're creating a 'product' anyway... just make a 'dummy' class that you can use for storage.

(Are you looking for a dynamic traversal interface that would allow you to map URLs to objects that are managed by ZPatterns? Can you give an example?) Reading this just after reading the source to Specialists.py, I had a thought; and tried it out; and it works! :-) You can use SkinScript to define __bobo_traverse__ for a particular kind of DataSkin in a Specialist. For example: WITH SELF COMPUTE __bobo_traverse__=traversal_method Then, define a method in the specialist (or rack) called traversal_method. I used a PythonScript, and gave it the parameter list "REQUEST, name". Make your method return the appropriate object to traverse to from your DataSkin, depending on the name passed. Something like return getattr(container.path.to.somewhere, name) That's the simple version, and it won't give the traversed-to object the correct context most of the time. To do that, I'd need to use an external method, and use the __of__ method to give the returned object an appropriate context. However, it is a start, and proves that it can be done. Take a look in the __bobo_traverse__ method of Specialists.py (from ZPatterns) for a good algorithm for traversal. The variable _marker is almost always a class attribute initialized to [], to make a unique object, as a sentinel. -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

Re: [Zope] is it possible to import from Excel
When on a windows platform, I prefer to define an ODBC datasource on the excel spreadsheet, write ZSQL method that selects the fields to be imported, write a DTML method that iterates on returned records and call another ZSQL method that writes into Gadfly. You may need to handle None/Missing values to prevent from ending up in gadfly as 'None' etc. If your not want to be tied to ODBC and Excel on the deployment platform, you can always try saving the content of the Excel sheet in a text format, if that is possible for your kind of data? The text file could then be parsed by at external method or even imported to the TinyTable product. On lage amounts of data this could be quite time consuming. So it would probably be more efficient to write a seperate import program. There might even be one for Gadfly. In that way you don't have to use a "unreliable" HTTP connection when importing data. That's my 25 öre (which is approximatly 5 cents) Regards, Johan Carlsson "How about Office 2000? Can it export data as XML?

[Zope] index_html woes - solved!
However this is not working, anymore I might add. I cannot say what I have done wrong. The only thing I've done is to add and remove SiteRoots with SiteAccess2 (which btw i cannot make work, and has caused my zope to die abruptly, w/o leaving trace in the logs). I don't know if this is related, but i thought i'd mention it anyway. Hello! I solved this myself. Naturally, it was my own stupidity: it turns out that in order to have a template permeate down to the sub-folders, it is necessary to make it a dtml-method and not a dtml-document.

Re: [Zope] Urgent Help, raise CorruptedTransactionError, message
Daniel,
You may wish to try the fsrecover script (shipped with Zope) or Ty Sarna's
"tranalyzer" product to figure out where the bad transaction is and truncate
your Data.fs to that point. There is a how-to on Zope.org by Itamar about
doing just this at this location:

[Zope] Question on __roles__
I have encapsulated most bits of my software in a product. One part
simply shows database objects, and I've made a base class to
handle most of the showing and editing stuff. In the base class,
I keep a tab on what methods etc. are used for viewing and for editing,
and I use these in the concrete classes to set the roles. Eg:
Base.py:
class Obj(OFS.SimpleItem.Item, Acquisition.Implicit,
AccessControl.Role.RoleManager,
AccessControl.Owned.Owned):
view_objects = []
index_html = HTMLFile('default_view', globals())
view_object.append('index_html')
... etcetera
Customer.py:
class Obj(Base.Obj):
__ac_permissions__ = (
('View Own Info', Base.Obj.view_objects),
)
...
Globals.default__class_init__(Obj)
As far as I can see, this is all by the book. The whole idea is that the
set of methods is the same, but the permissions on them can differ (for
example, there are special restrictions on viewing and editing invoices).
However, these protections don't work in most cases. They seem to work
when they pertain to methods, but they don't when they pertain to DTML files.
Is there something in the base class' base classes that influences how
role lookup works?
I've tried to trace down what happens, and found that ZPublisher.BaseRequest
has a funny bit: when trying to find out the necessary roles on an object,
it first tries to get the attribute '__roles__' on the subobject, and then
combines the current entry name plus '__roles__' and tries to get that from
the subobject. However, it seems to me that the latter getattr() needs to be
done on the object, not the subobject - at least, my tracing seems to indicate
that if it walks down, say 'Customer/53/index_html', that at a certain moment
during the traversal
object = Customer instance
subobject = Python method
entry_name = 'index_html'
Here, looking up "index_html__roles__" in the subobject, the index_html
method, doesn't seem to be very useful - it is expected to be found on
the containing Customer instance. And indeed, if I change line 386 in
BaseRequest.py from:
roles = getattr(subobject, entry_name+'__roles__', roles)
to:
roles = getattr(object, entry_name+'__roles__', roles)
things work as I expect them to work.
As this is such a core piece of Zope, it seems quite unlikely to me
that I found a bug here (although an older version of ZPublisher does
check object instead of subobject). The only thing I can think of is
that Acquisition should work for the getattr() and somehow I managed
to disable Acquisition on these instances.
Any hints as to what I'm doing wrong?

Hi Steve, It works! Thank you. Still there's a couple of things to be cleared. What's the use of 'otherwise' clause? And is it true that the 1st 'with' clause fails, the whole skinscript process fails (so one 'with' clause is all one skinscript can put up with)? Dirksen __ Do You Yahoo!? Yahoo!
