copied!<p>IMO, the breadcrumb relates to the set of controller actions taken to get to the current page or the action's place in the hierarchy of the site, depending on your interpretation. From that perspective, the controller seems the natural place to construct the data for it, though the rendering should occur in the view. In order for it to be completely generated in the view, you would need to either expose details about what controller action is being invoked by the view or have a fixed view-per-action model so that the breadcrumb for each could be precalculated. Moving the logic for computing the breadcrumb to the view itself seems to violate the separation of concerns in MVC and may preclude reusing views for different actions, which would violate DRY></p> <p>In my opinion, generating data for the breadcrumb is a cross-cutting concern in the controller, i.e., you have some shared code that runs regardless of the action that uses the url to construct the breadcrumb data. There is also some shared view code that takes the controller-supplied data and renders it consistent with the design.</p> <p>Note that I'm speaking from a purely architectural perspective. I'm not familiar enough with CakePHP (or other PHP frameworks, for that matter) to even judge whether your observation about it is correct. From a pattern perspective, putting it in the controller seems like the right thing to do. In a given implementation, though, it might make sense to violate the pattern.</p>
