RE: [Zope] adding dtml/zpt methods to product classes
by Pascal Peregrina 28 Jan '05

Why don't you simply define the DTML/ZPT objects attributes outside any class method ? class HyperTextArea(Implicit, Globals.Persistent, RoleManager, Item): my_method = Globals.HTMLFile("dtml/my_method",globals()) my_new_method = Globals.HTMLFile("dtml/my_new_method",globals()) ... This is what I do, and any new DTML/ZPT object I define that way gets added to any existing instance of this class type when I restart Zope (or when refresh my product). Pascal -----Message d'origine----- De : zope-bounces+pperegrina=lastminute.com(a)zope.org [mailto:zope-bounces+pperegrina=lastminute.com@zope.org]De la part de Keith Alperin Envoyé : vendredi 28 janvier 2005 04:59 À : zope(a)zope.org Objet : [Zope] adding dtml/zpt methods to product classes Greetings Zopistas! I have been a Zope tinkerer for a few years and have never been able to adequately solve this problem: When I create a Product class with DTML/ZPT methods, how can I make those methods members of the class rather than simply instance methods? These examples should illustrate what I mean. My first try was like this: class HyperTextArea(Implicit, Globals.Persistent, RoleManager, Item): def __init__(self,resourcePath, imageFolder): self.my_method = Globals.HTMLFile("dtml/my_method",globals()) That works fine until you want to add a new method to your class like so: class HyperTextArea(Implicit, Globals.Persistent, RoleManager, Item): def __init__(self,resourcePath, imageFolder): self.my_method = Globals.HTMLFile("dtml/my_method",globals()) self.my_new_method = Globals.HTMLFile("dtml/my_new_method",globals()) new instances of your product will get the my_new_method, but instances that have already been created will not. My second try was like this: class HyperTextArea(Implicit, Globals.Persistent, RoleManager, Item): def my_method(self, REQUEST): """ template """ if (not hasattr(self,"my_method_member")): self.my_method_member = Globals.DTMLFile("dtml/my_method",globals()) return self.my_method_member(self,REQUEST) This allows me to add methods to the class at any time and all instances will get the method. However, for some reason, when I use this pattern, i get strange acquisition results (for example, some of my objects children's dtml methods will use the parent's namespace for lookups). Currently, I'm doing this: class HyperTextArea(Implicit, Globals.Persistent, RoleManager, Item): def my_method(self, REQUEST): """ template """ self.my_method_member = Globals.DTMLFile("dtml/my_method",globals()) return self.my_method_member(self,REQUEST) which seems ugly, and like it might have performance problems, but i haven't had any acquisition problems yet. My real question here is: What is the standard way to handle this problem of being able to add dtml/zpt methods to classes such that all instances of those classes get the new methods? Thanks in advance for any insight.

zopectlsocket dies
by Michael Williams 27 Jan '05

27 Jan '05

My plone site died today and I can't get it running again. I have located the following entries in my logs: In /var/log/messages: zopectl: Unlinking stale socket /var/lob/zope-2.7.2/main/var/zopectlsock; sleep 1 zopectl: . After each restart attempt: zopectl: daemon process started, pid=xxxx "14 seconds later" zopectl: daemon manager not running event.log: I'm getting ZODB conflict errors When the zopectlsock dies it leaves Z2.pid and Z2.lock but no corresponding process is running. I've checked around the web and can't find any solutions. Hopefully someone here can help?

Using pychart from a Zope product
by Reuven M. Lerner 27 Jan '05

27 Jan '05

Hi, everyone. I'm developing a Zope application that needs to do simple line-charts, and PyChart looks like a good solution to my problems. I was able to install PyChart without any trouble, and I also ran the command-line tests without any problems. But when I stick an example into a Zope product and invoke it, I get nothing -- not an error message, not an output chart, not a security violation of some sort... nothing at all. I know that PyChart is being invoked, because I can force an error by invoking theme.get_options(), which throws an error due to the lack of command-line options. I see from the various Zope mailing lists that people are using PyChart, and I have a feeling that I'm missing something obvious. But if someone has an idea regarding what I should be doing in order to get PyChart to work, I would greatly appreciate it. Thanks! Reuven

Calling a Z SQL Method
by Asad Habib 27 Jan '05

27 Jan '05

I have a Z SQL method that contains a simple SELECT statement and takes no arguments. When I call this Z SQL method from a DTML document/method I use the following: <dtml-in retrieve_names_sql></dtml-in> This works just fine. However, when I place the Z SQL method inside a Folder called selects and then use the following, I get an error: <dtml-in "selects.retrieve_names_sql"></dtml-in> The error I get is the following: KeyError: 0 On the other hand, when I use the following I do not get an error: <dtml-in "selects.retrieve_names_sql()"></dtml-in> I understand the difference between the 2 <dtml-in> statements but why isit that I have to explicitly show that retrieve_names_sql does not take any arguments in the latter case and not the former. The id of this Z SQL method/Zope object is retrieve_names_sql and it seems to me that this should be recognized within the object hierarchy. Any help/input would be greatly appreciated. Thank you. - Asad

Generating editable grid with Zope2.6/ZopeX3?
by Florian Reiser 27 Jan '05

27 Jan '05

Hello, I want to generate an editable grid with Zope (2.6 or X3). E.g. Field 1 | Field 2| Field 3 -------------------------- Id 1 | Edit 2 | Edit 3 Id 2 | Edit 2 | Edit 3 Id 3 | Edit 2 | Edit 3 . . . I've already looked into Formulator for Zope 2.6, but this product doesn't seem to be able to render :records objects. Is it possible to render such a form with zope? Manual alignment is ok, but I would like to use the input validation mechanisms that are provided by Formulator or ZopeX3. Regards Florian -- Sparen beginnt mit GMX DSL: http://www.gmx.net/de/go/dsl

How can I searchResults NOT containing a specific path
by Massimo Coletti 27 Jan '05

27 Jan '05

Looking at the documentation, I see that path searches allow me only to select items when they HAVE a specific path. Is there any way to EXCLUDE objects with the specific path (i.e. a negate clause)? Many thanks, Massimo
