Sounds somehow more like all you need is to learn about __getattr__ and
maybe __call__ instead of actually generating methods. In other words,
don't generate anything, just intercept attempts to call things that
were produced by accessing the attributes of an object.
Whether that would work or not depends on things you haven't said. The
above spec is a little unclear, given among other things that you don't
"call method names", that the code in the methods you would presumably
want to call has to exist somewhere and you haven't described what that
code would be, and I can't tell what those database "entries" are really
all about other than that they somehow refer to the names of things that
you think you want to call as methods. :-)
Perhaps an example is in order...
