[Zope-dev] ZPatterns: SkinScript semantics
In a SkinScript COMPUTE statement, should I be allowed to supply different names in the OTHERWISE LET section as in the attributes section? For example: WITH some_query() COMPUTE foo,bar,baz OTHERWISE LET foo='There is no foo', spoon='There is no spoon' Looking at the ZPatterns code, I don't think this attribute provider will get registered for providing "spoon", although "spoon" will get calculated if foo, bar or baz is requested. On the other hand, you could consider the above as a shorthand for: WITH some_query() COMPUTE foo,bar,baz, spoon=NOT_FOUND OTHERWISE LET foo='There is no foo', spoon='There is no spoon' In which case, it works entirely as expected. -- 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 )
[Zope-dev] ZPatterns patches
I've put an extensive patch to ZPatterns 0-4-3b2 here: http://www.cat-box.net/steve/ZPatterns.patch The patch includes the following: * Fix to _memento class so it works with Zope 2.3 * Alteration to GAPMixin so the the attributes it says it provides come from the union of the assignments and the defaults. * Add style="width: 100%;" to SkinScript edit textarea, in line with other zope textareas. * Add syntax to SkinScript "INVALIDATE FOR". You can put an optional invalidate-for clause at the end of a compute statement. This causes the attributes provided by the statement to be invalidated from the dataskin's attribute cache when any of the attributes named after INVALIDATE FOR change. It is easier to demonstrate than to explain :-) There's also an updated PlugIns/www/main.dtml file at: http://www.cat-box.net/steve/main.dtml An example of the new SkinScript syntax: WITH SELF COMPUTE name='%s %s' % (forename, surname) INVALIDATE FOR forename, surname This is useful if you're providing attributes from another DataSkin. Here's an example from some school management software. This is an attribute provider for Pupils. A Pupil may have an Instructor. This is implemented by the attribute instructor_id of Pupil. # the instructor is only valid if the pupil is current WITH SELF COMPUTE has_instructor=instructor_id or 0 and current and 1 # don't use has_instructor below, or the instructor details for # cataloging won't get updated when the assigned instructor changes # from no instructor to having an instructor. WITH self.instructor_id and self.current and Instructors.getItem(self.instructor_id) or NOT_FOUND COMPUTE instructor_name=name, instructor_name_link='a href="%s"%s/a' % (absolute_url(), html_quote(name)), instructor_sort_key=sort_key, instructor=RESULT OTHERWISE LET instructor_name='no instructor', instructor_name_link='no instructor', instructor_sort_key='', instructor=_.None The problem here is that I can't use has_instructor in the WITH clause, if I'm also using has_instructor in the same transaction as I'm updating instructor_id. I have to use "self.instructor_id and self.current" instead, as above. However, with the new syntax, I don't have to worry about that: # the instructor is only valid if the pupil is current WITH SELF COMPUTE has_instructor=instructor_id or 0 and current and 1 INVALIDATE FOR current, instructor_id WITH has_instructor and Instructors.getItem(self.instructor_id) or NOT_FOUND COMPUTE instructor_name=name, instructor_name_link='a href="%s"%s/a' % (absolute_url(), html_quote(name)), instructor_sort_key=sort_key, instructor=RESULT OTHERWISE LET instructor_name='no instructor', instructor_name_link='no instructor', instructor_sort_key='', instructor=_.None Thanks to PJE for pointing me in the right direction on how to implement this. -- 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 )

[Zope-dev] Added rename to ZOPE FTP server
Hi, I've added the rename capability to the Zope FTP-server, so I could use the KDE FTP client (this is a known Zope bug). I attached the 3 modified files (from the 2.2.5 src distro). There is however another problem in the ZOPE ftpd which is probably not related to my patches, but for which I have not found the cause. The SIZE command (used by the KDE ftp-client as a kind of file-exists probe) reports the size of identical named objects higher in the tree, to reproduce: copy with the KDE FTP client a directory tree which has fileabc in the top directory and a file "fileabc" in a subdirectory to the Zope ftp server. The SIZE command returns a size (for a non existing object!) but the LIST command works o.k.

[Zope-dev] Better test case for Bug 1783: Persistent __call_method__() interferes with __getstate__
Hello all,
The following is the best test case I have so far for bug 1783.
The behavior of the bug is that no CMethods from Persistent can be
called indirectly when the __call_method__ hook is present. This means
that I can't override any of __getstate__, __setstate__, _p_deactivate.
#!/usr/bin/python
import ZODB
from Persistence import Persistent
class P(Persistent):
def __call_method__(self, meth, methArgs, methKW={}):
return apply(meth, methArgs, methKW)
p = P()
p.__getstate__()
#This throws exception!
Persistent.__getstate__(p)
TypeError: function requires exactly 0 arguments; 1 given

But even if I did this, how do I say I want basic auth if the test cookie isn't found. Doing a: raise "Unauthorized" or RESPONSE.setStatus(401) will tell the browser to pop up an authorization dialog. Note that if you do this, you won't be able to also display a login form for cookies.

[Zope] specifying namespace stacks in dtml-with
I was thinking about something I'd consider a useful addition to the dtml-with tag; I'd like to get other people's opinions, especially about a couple syntax issues. Problem: In part because of the combination of the dtml namespace stack and acquisition, it's often hard to get exactly the name resolution you want in Zope. For example, I think it's really useful to want the following: "Call an object, found by acquisition, using its "natural" namespace, except include a small number of symbols found in the local namespace. When evaluating the local symbols, do so in the local namespace." Why is this useful? Because it cuts down on accidental interference of the local namespace in the evaluation of an object, which acquisition exacerbates because it multiplies the number of symbols in the local namespace. I'd even go as far as to say that the above action is what most people want to do most of the time. How do you do it? If you do: dtml-with object dtml-with expr="_.namespace(name1=local_object1, name2=local_object2)" dtml-var object /dtml-with /dtml-with (or the equivalent using an inner "let" tag instead of "with") you get the right nesting, but "local_object1" and "local_object2" are evaluated in "object"'s namespace, not the local one. I *think* the only way to do it right (I haven't tried it) is: /dtml-let ns="_.namespace(name1=local_object1, name2=local_object2)" dtml-with object /dtml-with ns dtml-var object /dtml-with /dtml-with /dtml-let That way, you can get a namespace evaluated in the local scope onto the top of the namespace stack to override the object's symbols. You've got to go through contortions to swap the order of the namespace stack without introducing unwanted evaluation side effects. Yuck! I think is would be much cooler, and more general, to be able to specify a namespace stack as a list for dtml-with: dtml-with "[_.namespace(name1=local_object1, name2=local_object2), object]" /dtml-var object /dtml-with The "with" tag's entire expression would be evaluated in the local scope, *then* a namespace stack would be constructed, using elements of a list. If you had several objects already, the syntax is even cleaner: dtml-with expr="[object1, object2, object3]" ... /dtml-with In short, this construct lets you build a well-defined namespace stack without worrying as much about unwanted scope interaction. It's even not that hard to write the implementation, except for a couple questions. -- First, the "mapping" attribute to "with" is per-namespace; how do you specify it for elements of the stack? (The "only" attribute is okay, it is specified once per stack.) It would be limiting to say that all namespaces pushed onto a stack would need to be all be mappings or all be objects. -- Second, is the expression for "with" currently ever a sequence? If so, then you'd have to recognize and distinguish between the old and the new usages. I don't think there's much of a problem here, although the "with" tag code does do a little checking about whether its expression is a tuple. -- Finally, what's the natural order of the stack? If you give the argument "[a, b, c]" to "with", is "a" or "c" on the top of the namespace stack? I'd probably say "a". I'd appreciate any ideas/suggestions others may have. Thanks!

[Zope] Re: Workflow and document management system in Zope
Dear Mr Boulanger, Thank you very much for your input. I don't think there is such as system polished and ready within 2 weeks. I do NOT need a polished system within 2 weeks. I need a proof of concept . The production system shoudl run in 2 or 3 months ... and could be optimized afterwards also, in order to be polished. If it is well though already this should be possible. What could you do or take in charge ? Best regards, Nicolas Pettiaux Le Samedi 20 Janvier 2001 00:51, albert boulanger a crit : I am looking for a workflow (WF) linked to a electronic document management (EDM) system and a groupware email based (I have just happened to come accross aethera from the Kompany) that would be free software and preferably in Zope + Python. The WF+DEM system I am looking for need to be usable with only a browser (to be independant from the client ... that could be proprietary !), store its data into a postgresql database. It should be demonstrablable (at least showable into a proof of concept) within 2 weeks and be already installable and usable within 2 or 3 months. (I have obtained taoday that the date when we'll decide on the system would be postponed 2 weeks from wednesday 24/1 to wed 7/2) If I could find such a marvel, I may find the money to pay for it, at least 5 $ to start with (this amount is a rapid guess; I may give more precise amounts we could spend in the following week) The idea is to use that combination of tools INSTEAD of buying a closed, proprietary solution (that may exist but be expensive and really har to parametrize), that NEED to be linked to a SAP ERP system. All suggestions and ideas are welcome, also on the selection criteria. (I happen to be responsible for the IT dept of the public institution that wants to buy such a tool, but be new in the place and do not yet know a lot about WF and EDM !) Soon I may be able to give you more details about the requirements. I don't think there is such as system polished and ready within 2 weeks.

[Zope] __setstate__ and acquisition
I am using __setstate__ to reload files into memory for objects of a product I have made. This all works nicely, as is it supposed to. The problem though is that the object seems not to know about its environment at that time, i.e. it cannot acquire methods further back in the hierachy, but is able to perfectly well once it is fully instantiated. For example a product method may call a render method that exists quite root to the whole site. This product method will work fine when the object is fully instantiated , but trying to call that render method during __setstate__ fails. regards Matt ___ 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] if-else using ZSQL resultset sendmail query
Hi, I've got a few questions, which may be answered by saying, "Not possible"! Any feedback would be appreciated. get_testclass_details is a ZSQL method returning user data from a table. I display the data (strangely enough) in an HTML table and I want alternating rows to have different background colours. I figure that the best way to do this is to obtain the resultset number (i.e. is it the 1st, 2nd or 3rd result row) and do something like the following; dtml-in... if (the result set number % 2 == 0) bgcolour is white ... else bgcolour is grey ... /dtml-in... Is it possible to obtain the resultset number? Also, re: sendmail. I still haven't managed to figure out why it's not posting messages to newsgroups. Maybe some folks at digicool could let me know if this isn't supported? Previous message was: I have another question re: sendmail, which I'd be grateful if someone could answer.

Re: [Zope] __setstate__ and acquisition
That makes sense. Is there any way to explicitly pass the surrounding namespace to __setstate__ ? The problem is this : my product is really a handle to methods that create or update files on the local filesystem. Previously I have been building filenames and paths within the product and then setting them as an attribute of the object. However it is nicer for the path components to be acquired from the current folder/container properties so that an object knows it's location by way of the environment it is in. The reason for this ? I have almost got my product to the state where is has no persistent attributes, it is instead a rich set of functions that when instantiated, will use its current environment to build the datafiles path and name, pick it up or make it, create some volatile objects, and then allow the user to action one of the many functions it provides. The reason for this, the volatile objects can be huge, and I have thousands of these. The only thing that ever persists is the id. So getting back to the first point, if __setstate__ could somehow access the sorrounding namespace, then that would make it easier. For now I have a swtich in the get_filename method, which is called both by __setstate__ and by other functions in the product. The switch says : try finding these acquired features, if you can't then use the local copy of where you last thought you were. Then once the object is instantiated any updates that also call this function will naturally find the new acquired attributes. This however forces you to make sure a previous copy of a file still resides in the old location. matt Evan Simpson wrote: From: "Matt" [EMAIL PROTECTED] I am using __setstate__ to reload files into memory for objects of a product I have made.

[Zope] SQL query result set - what data structure how to access [(elements)]?
Hi,
I'm using a python method to query my database as follows, where I need
to use the result set to generate some HTML. I'm interested in result[0]
and result[1] as listed below;
* return result[0] gives me:
[{'name': 'PRACTICALS', 'type': 's', 'null': None, 'width': None},
{'name': 'TUTORIALS', 'type': 's', 'null': None, 'width': None},
{'name': 'ASSIGNMENTS', 'type': 's', 'null': None, 'width': None},
{'name': 'BONUS', 'type': 's', 'null': None, 'width': None}]
* return result[1] (or just 'return result') gives me:
[(1, 16, 9, 1)]
What kind of data structure is this? First impressions suggest that it's
a tuple but why the extra brackets?. I need to access each element but
how do I do this? I've tried all sort of tuple/list
conversions/operations and have had no success.
If the result is [(1, 16, 9, 1)] how can I assign...
a=1st element i.e. 1
b=2nd element i.e 16..?
I can convert it to a string, parse it and obtain the results that way,
which is simple enough, but surely there's a way to access the element
directly? Does anyone know?
Thanks,
Lee
