Extending
Views
So far, you've experienced amazing power in a
short time. Rails Active Record has let you build surprisingly
capable models with no more than a handful of lines of code.
Scaffolding used the metaprogramming capabilities of Ruby in
concert with the metadata in Active Record to instantly slap a web
face on our database tables. The Rails generators and glue code
kept the structure consistent and provided the necessary tools to
develop and debug the application at every step of the way. Now
that we have scaffolding in place for our database tables, its time
to start replacing that scaffolding interface with a prettier
interfaceone that lets us manipulate the relationships between our
tables.
This will happen faster than you might think;
now the fun really begins, as our web application's user interface
rapidly take shape. In this chapter, you will see how to:
-
Take control of the views rendered through
scaffolding
-
Handle relationships in our views
-
Manage layouts
-
Make a simple change to Rails routing
-
Manage styles
