Should a view call a helper function?
Say I pass in data from the DB to the view. The data is a unix timestamp. Should I make a call in my view to convert it to a human readable TS or should I convert it in the controller before passing it in? OR should I make a method in the model that converts...
Looking for a "best practice" or "secure coding" concerned answer.
This seems like a fairly trivial calculation, indeed, you could implement it in a few lines of javascript. It is your view that is in charge of displaying data; let it do its work.
Since human readability depends on the target output device (big screen TV, dashboard display, watch face, voice synthesis, Morse code tones/blinks, etc.), it might be best to customize this readability in the object most closely associated with the physical output device, likely the view object. The model objects can keep and pass on a binary encoded or computationally suitable form.
