Quick Acquisition Question
by Ronald L. Chichester 22 Aug '01

22 Aug '01

I have a ZClass that acts as a 'parent' folder for a number of similar ZClasses (similar in that they have all the same properties EXCEPT the property amParent is TRUE for the parent only (FALSE for the children). The child folders in question (as well as the parent) can contain instances of other ZClass objects. My question is, if I am in a child folder buried deep down in the branch having a parent as a root note (NOT the root folder), how can I get a list of the instances of the other ZClasses in ALL of the other child (and parent) folder? The next question is, the parent folder has a set of special folders containing, for instance, a set of contacts (ZClasses). If I am way down the tree (by an arbitrary number of intermediate folders), how would I refer back to the 'contacts' folder in the parent folder? As far as the folder in question is concerned, its parent is the child of another folder. I don't want to go all the way back up to the root node, just to the folder object that satisfies a certain condition. I've read up on acquisition, but it doesn't seem to be answering my questions. TIA, Ron

rendering image tags (corrected)
by hamish＠allan.tc 22 Aug '01

22 Aug '01

sorry - there was a mistake in the dtml-in expression in my earlier query. here it is corrected: ---- hi folks, suppose i have some images in a folder, named image1, image2 and image3, and the following DTML method: <dtml-in expr="['image1', 'image2', 'image3']"> <dtml-var expr="_.getitem(_['sequence-item'])"> </dtml-in> this yields something of the form: <img src="http://localhost:8080/test/image1" alt="image one" height="32" width="90" border="0" /> <img src="http://localhost:8080/test/image2" alt="image two" height="32" width="90" border="0" /> <img src="http://localhost:8080/test/image3" alt="image three" height="32" width="90" border="0" /> (incidentally, this is the case whether or not i pass 'true' to the 'render' argument of getitem()). first question (the answer to which is probably obvious, but i'm new to zope): - why does the following not yield the same result? <dtml-in expr="['image1', 'image2', 'image3']"> <dtml-var sequence-item> </dtml-in> (yields: image1\nimage2\nimage3) second question: - i want to pass an extra argument to the image object. the following code works: <dtml-in expr="['image1', 'image2', 'image3']"> <dtml-var expr="_.getitem(_['sequence-item']).tag(name=_['sequence- item'])"> </dtml-in> yielding: <img src="http://localhost:8080/test/image1" alt="image one" height="32" width="90" border="0" name="image1" /> <img src="http://localhost:8080/test/image2" alt="image two" height="32" width="90" border="0" name="image2" /> <img src="http://localhost:8080/test/image3" alt="image three" height="32" width="90" border="0" name="image3" /> but this is based on knowledge that Image.__str__() calls tag(), which i do not want to rely upon. instead i want to call the object in the same way as it is called when i use a simple tag such as '<dtml-var image1>'. how do i achieve this? (using expr="_.getitem(_['sequence-item'])(name=_['sequence-item'])", i.e., dropping the '.tag', yields an AttributeError of value __call__). thanks in advance, hamish -- Get your firstname@lastname email for FREE at http://Nameplanet.com/?su

C++ style comments confound Sun compilers
by payne＠stsci.edu 22 Aug '01

22 Aug '01

I came across this again building 2.4.1b1, but there are C++ style comments in lib/python/Products/PluginIndexes/TextIndex/Splitter/ISO_8859_1_Splitter/src/ISO_8859_1_Splitter.c that prevent a clean build with the Sun version 5 compilers, at least for me under Solaris 8. Could they be changed?

Oracle Stored Procedures and Transactions
by alan runyan 22 Aug '01

22 Aug '01

I have a Script (Python) that does the following: stored_proc.AddUser stored_proc.AddTrees does some funky Python stuff zsqlmethod.insertPermissions I've had cases that my insertPermissions explode but the stored procedures have committed their data -- regardless of the transaction needing to be rolled back. In ZOPE, am I correct that everything inside a Request is in one Transaction (btw, how do you demarcate transactions?). Am I missing something? I am expecting that everything would be rolled back on a exception but it appears not. ~runyaga
