What's the best way to define variables to be used in a parameterized DTML document? Let's say I have a folder hierarchy where all the folders can share a single index_html at the root, except that there are a couple of differences in various places that are not directly derivable from the usual variables (id, title, etc.). For instance, an organization chart represented as a folder hierarchy, and a standard welcome page that includes among other things the physical location of the part of the organization represented by the selected folder and the phone number of the receptionist at that location. My index_html page could have <dtml-var orgloc> and <dtml-var receptPhone> buried in it somewhere, then all I have to do is define orgloc and receptPhone at appropriate places in the folder hierarchy. I could of course make them DTML Methods that just returned a string, but it seems pretty heavy-handed to define a method just to get a variable value. Is there a better way to specify variable values? Some kind of dictionary mechanism? Suppose I had 10 or 20 such variables -- I wouldn't want to deal with the proliferation of one-line DTML Methods throughout the hierarchy. I just want a way for each folder to register values of whatever variables it wants to override, for use by parameterized pages. One thought I had was to subclass ObjectManager (either in Python or as a ZClass) and add a mechanism that looks in a dictionary stored in a "variables" instance variable, then if the desired variable wasn't there, look at the parent, etc. Before I launch off into this escapade, please tell me if (a) there's a straightforward way to define variables like this; (b) the whole idea is confused; or (c) there's an available Product for this.
