Therefore, when index_html looks for header, the content folder is searched, then the home folder, then the lowres folder, then the home folder. Unfortunately, for our example, the header is found in the search of the home folder, and we never make it to the lowres folder.
Oops--thanks for pointing that out. I sometimes wonder, however, why it was set up this way. Except for speed concerns, I see no reason why, if we set up the algorithm a different way, it couldn't search from right to left. A simple approach would be like this: def findattr(obj, name): while (obj is not None): base = getattr(obj, 'aq_base', obj) if hasattr(base, name): return getattr(obj, name) obj = getattr(obj, 'aq_parent', None) raise AttributeError, name
Hope this makes sense. Acquisition is not one of the things I have become good at explaining, yet. The slides from Jim's Acquisition Algebra talk is about the best source of information on this subject.
Of course, Jim would probably look at my example and want to hit me. He likes things to be optimized. :-) Shane
