Hi ! We are using Zope 2.1.6 for Windows NT Server, and Oracle 8i as RDBMS. When the ZSQL methods are runned, the values of the parameters of the SQL query are remplaced by Zope before sending the query to the Oracle database jet (it does not the "parse"). Thus, if two users runs the same query but with different parameters, it is considered as two different queries because the values of the parameters of the ZSQL method are remplaced firstly. When it is realized by more users with diferent parameters, the Oracle's cache is fulling quickly and it is overing. Do exists any way for sending the query of the ZSQL method and theirs parameters, trying that the values of the parameters was remplaced in the database jet, and no previously. Perhaps, it was a ODBC problem, or the Zope code does not allow it. I do not know it. Any body can help me ? Thanks.

Re: [Zope-dev] Custom dtml tag
Really? Ive looked up this and get nothing (an attribute error actually) and
its not in globals. If that would work that would be great - but a it
certainly doesnt seem to on a standard DTMLDocument / Method.

Re: [Zope-dev] Custom dtml tag
Andy: here's what I've gleaned - in a dtml tag's render() method, you
get passed in self and a template dict, in my example let's call it
'md'. md is essentially a stack/dictionaryish object of the *current*
namespace - and one of the handy things that's always around in the
namespace is the 'this' function, which returns the object on the top
of the stack.
Just lookup 'this', run it, and there you have a reference to the
calling object! Ex:
def render(self, md)
this = md.getitem('this')
callingObj = this()
return "Calling object was %s" % (callingObj.id())
Note I haven't tested this code. Good luck!

Do I have to run render_blocks() to insert my new > object into the namespace? TIA There are two seperate things here: The namespace, and the ZODB. I am assuming you want to add an object to the ZODB. The namespace reflects, amongst others, the attributes on the current object, and if it inherits from Acquisition.Implicit, the rest of the ZODB contents. You can add additional lookup objects to that stack, and anything using the namespace can then access those extra attributes. (render_blocks() is just a call to render all DTML contained within the with tag, and the with tag then removes all additions to the namespace again with md._pop() at the end.) If you want to manipulate the ZODB, you can just take a reference to the object you want to manipulate (add subobjects to), and add these directly as attributes. Or better still, if the object inherits from ObjectManager (like a Folder), use the ObjectManager API to add objects. If the subobjects in question are standard Zope objects, use the Class Factory API that the 'Add' list in the management interface uses. Important to remember is here that the namespace only gives you access to the objetcs. Adding to the namespace only gives you a larger namespace, which only has meaning in the context of the current DTML code tree. If you want to manipulate the ZODB contained objects, manipulate them directly. -- Martijn Pieters | Software Engineermailto:[EMAIL PROTECTED] | Digital Creations http://www.digicool.com/ | Creators of Zope http://www.zope.org/ | ZopeStudio: http://www.zope.org/Products/ZopeStudio - ___ 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 )

Ok, so render gets passed 'md', which is a TemplateDict, which contains a MultiMapping, which looks like a stack of dictionaries, which I am guessing is some sort of namespace stack. So looking at the DT_with.py, it looks like, to create an object in the current namespace, I have to wrap it in an InstanceDict, and push it onto the 'md' using 'md._push'. Does this also cause the new object to be saved in the ZODB? Or do I have to manually add it there too? Also, what does render_blocks do? Why does DT_with.py's render() return it?
