Well... The canonical definition of boolean stands for TRUE and FALSE. Actually BOOLEAN is something, conceptually, bigger than MySQL. http://en.wikipedia.org/wiki/Boolean_data_type As MySQL did NOT, as of 5.0.SOMETHING, have the most near datatype for BOOLEAN which is BIT, they shortcut it to TINYINT(1). Which, by definition IS NOT boolean, as it may store integer numbers up to 2^8 or 2^7 plus sign bit (-/+). I particularly used, up to emerge of BIT datatype, TINYINT(1) to store up to 10 different status of something. 0 - means X, 1 - means Y and so forth. Either INT(1) or TINYINT(2), which workarounds the problems, are fine. I just wanted to pointed this behaviour somewhere so as to avoid confusion. It is NOT documented in CakePHP docs. Nowhere. No fix requested.
