Hi, I've been playing around a bit lately with using pluggable brains for SQL methods from within a Python Product I'm working on. In the Content Managers Guide there's a section which discusses the use of External Methods and Pluggable Brains with Products and gives the following (shortened) descriptions:

For example, suppose an external method or brain is defined using the file name foobar.util, then Zope will attempt to load the method or class files from the following files, in this order:

1.lib/python/Products/foobar/Extensions/util.py 2.Extensions/foobar.util.py 3.Extensions/util.py

I tried this out within a SQL method that I created by enteing in a module name like this: 'myProduct.myModule'. I also entered the right mix-in class name which was in the module 'myModule. I already had created a Python Zope Product which resided in INSTANCE_HOME/lib/python/Products/myProduct and I also created an 'Extensions' sub-directory in this Product directory. So based on what the documentation said I thought I had set this up properly, but when I tried to edit the 'Advanced' tab of the SQL method it kept telling me that it couldn't find the module 'myProduct.myModule'. I looked in the App.Extensions.py source and (I think) tracked it down to the following bit of code (line 152): sw=path_split(path_split(SOFTWARE_HOME)[0])[0] for home in (INSTANCE_HOME, sw): #rest of loop... On my machine INSTANCE_HOME=/local/app/Zope and SOFTWARE_HOME=/local/app/Zope/lib/python So why does that first line effectively truncate the last two directories off of SOFTWARE_HOME, effectively making it equivalent to INSTANCE_HOME??? When I comment out that first line and change the second to: for home in (SOFTWARE_HOME, INSTANCE_HOME): #rest of loop things work as stated in the documentation. In any event I think I've found a bug here, either in the code above or in the documentation in the Content Managers Guide. Also I did try to see if this was in the Collector, and I did see an entry which may have been related to this, but it was still 'under review' so I could not view it to make sure. So if someone could shed some light on this bug(?) that would be great. Dave -- ---------------------------------------------------- David R.
