I'm using the Yii Framework which is an MVC php framework that is pretty similar to your standard web-based MVC framework.  I want to display the related data from a many-to-many table as a list of strings in my view.  Assuming a table schema like:tag { id, name }post { id, title, content, date }post_tag { post_id, tag_id }A post will display like:Date: 9/27/2012 Title: Some TitleContent: blah blah blah...Tags: Smart Funny Cool InformativeI can achieve this by doing something like this in my Post view:<?php  echo join(' ',           array_map(function($tag) { return $tag->name; }, $model->tags));?>(where $model->tags is an array of Tag objects associated with my model)My questions are:Is this amount of code/logic okay in the view? (Personally I think I'd rather just reference a property or call a single function.)If not, where should this code live? In the model? the controller? a helper?Potentially I may want to use in in other views as well.  Ultimately I think its purely a display issue which would make me think it should be in the view, but then I have to repeat the code in any view I want to use it in.
Where should display functions live in an MVC web app?
