Hello! I'm trying to write a small filesystems based product which I'm calling MovieWorld. The main class (MovieWorld) inherits from ObjectManager and is to be configured to contain a folder with images and a index_html page template (so that it can be edited via ZMI if needed). Setting these things up in a manage_afterAdd works fine as long as I'm just adding new products, but renaming or copying will cause manage_afterAdd to be called again, which fails because the objects to be created already exist. What should I do?
The obvious solution is to check for existance of the objects and only add them if they don't exist, which is what I tried. This worked for the folder called "images", but I was using hasattr(self,'images') to check to existance, so it worked by coincidence. What I mean is it works only if there is no object called images aquired, which means it also mus not exist anywhere along the aquire path. For this reason, hasttr(self,'index_html') will return true, and the index_html template will not be added at all. It seems I need one of three things: 1. A better way to add images and a template altogether. 2. A hook which is only called once, when the object is first created. 3. A method to check if the objects exist in the newly added item directly, not aquired.
