Constructor Details

#initialize(app = nil, message = "Response Time") ⇒ LayoutEngine

honestly, this is a hugely important file, but there shouldn’t be anything in this file that concerns regular developers or users. Here we figure out which is the current page, then collect which blocks go on a layout and which layouts go on a page. For each block, if it holds a model_display, we’ll call the controller for that model. treat your controllers and models like you would in a normal rails app. this does set some environment variables that are then used in your controllers, but inspect them there. if you’ve set up your page->layouts->blocks->model_displays->field_displays properly this should just work. if you’ve created a page using the gui and its not working.. check it’s path setting and check your routes file to see that they are looking right.
