I am fairly new to Yii but have experience with other MVC frameworks, such as RoR.
I’m building my first Yii app and am finding myself repeating code numerous times in a view file to check values of my models attributes (e.g. value > 0, value != ‘’, etc) and also formatting these values (mostly with number_format()).
My question concerns where to put this logic in order to "DRY" my code. Should it go in the relevant controller, or the model? I initially thought to put it in the model, maybe in afterFind() and beforeSave() (because I want to strip any formatting from numerical values before they go back into MySQL).
But I’m not sure exactly where to put it - maybe in a behavior or component? I don’t fully understand the purpose of those two elements yet, nor do I get the filter() functionality in Yii yet.
Can anyone point me to a tutorial or other reference that would provide a more detailed explanation of behaviors, components, and filters? Or maybe give me a frame of reference in terms of the corresponding elements in Ruby on Rails? I have read the Definitive Guide and API documentation concerning behaviors, components, and the filtering system, but I think I need to see some working examples to really grasp the potential they have.
Thanks in advance!
