    copied!<p>I suppose it should do justice to state what I think I know so far as well as what I've done:</p> <p>1) I created the app and did my first db migration; I know have my dev, test and production databases. The dev db has a table called 'wines'.</p> <p>2) I made a scaffold which created the necessary files.</p> <p>3) The basic index/update/destroy methods are set up and I can browse the pages.</p> <p>4) From what I gather, the ActiveRecord class "Wine" automatically inherits properties from the database? Each column is a property and each row in the table 'wines' is a potentially instantiated object which is called from the wine_controller script.</p> <p>The problem I'm having now is that I want to create a common layout that all controllers use. The only things that will change will be the page title, potentially some &lt;link&gt; tags in the header, the &lt;body&gt; attributes (javascript onload events most likely) and whatever lies inside the &lt;body&gt; tag.</p> <p>I find myself looking up functions that will do what I want (like "favicon_link_tag", "stylesheet_link_tag" and "auto_discovery_link_tag"...) but I can't find the right place to PUT them! I know this has something to do with my lack of understanding of how things are executed/inherited. For example if I were to declare @pageTitle in application_controller.rb and use @pageTitle in ApplicationHelper it won't work. Or even using "stylesheet_link_tag" in application_controller.rb throws an error. I'm just not getting something.</p> <p>How does each thing relate to another in terms of chronological execution, scope, etc.?</p>
