Guys,
I've been trying to implement mixins for the first time, using the
documentation as the leading source for how to do this. I've got
several models that need some checks. The implementation I currently
have is:
models:
Track
Release
class in lib/:
ValidationHandler
contains methods:
addBlocker()
addWarning()
getWarnings()
getBlockers()
in Track and Release, I've added a new method:
public function __call($method, $arguments) {
return sfMixer::callMixins();
}
and below the model definitions, I've added:
sfMixer::register('Track', array('ValidationHandler', 'getWarnings'));
sfMixer::register('Track', array('ValidationHandler', 'getBlockers'));
sfMixer::register('Track', array('ValidationHandler', 'addWarning'));
sfMixer::register('Track', array('ValidationHandler', 'addBlocker'));
in Track and:
sfMixer::register('Release', array('ValidationHandler',
'getWarnings'));
sfMixer::register('Release', array('ValidationHandler',
'getBlockers'));
sfMixer::register('Release', array('ValidationHandler',
'addWarning'));
sfMixer::register('Release', array('ValidationHandler',
'addBlocker'));
in Release
I have specific validation methods that are only called in some
situations, but when called, will be using addBlocker and addWarning
to fill up the warnings and blockers. Now when I trigger such a
situation, I get a lot of php warnings:
Notice: Undefined index: object in /usr/share/php/symfony/util/
sfMixer.class.php on line 165
Warning: call_user_func_array() [function.call-user-func-array]: First
argument is expected to be a valid callback,
'ValidationHandler::addBlocker' was given in /usr/share/php/symfony/
util/sfMixer.class.php on line 179
Now I found ticket #1038: http://trac.symfony-project.com/trac/ticket/1038,
which refers to Zend Optimizer changing PHP behaviour. Is this the
problem? Will mixins not work when using Zend Platform? Or am I doing
something stupid here?
