[erlang-questions] Can't create schema in Mnesia

[Yves S. Garret]

Hello all,

I have the following code:
http://bin.cakephp.org/view/2135184996

When I compile and reload the records, this is what happens:

14> c(mnesia).
{ok,mnesia}
15> rr("records.hrl").
[planemo,tower]
16> mnesia:setup().
** exception error: undefined function mnesia:create_schema/1
     in function  mnesia:setup/0 (mnesia.erl, line 25)

The function _does_ exist in the mnesia module.  I checked the docs and I'm
running 16B03, so it's there.  But why this error?

Also, I have an another question.  Lets say I'm testing some code and I
comment out where I'm calling a function (located in the same file.)  How
can I tell the compiler to not worry about this file not being called?  I
know I can for variables such as _Variable, but methods?
