Answer 1

Do you understand about RESTful? I assume that you know it, unless you can find it in rails guide (In form tag, you must add @student,:action => :new, :method => :post)
To add new record, just type Student.create(:name=> "a", :age => 2)
This statement is composed of 2 sentences

object = Student.new(:name => "a", :age => 2)
object.save

I suggest you use rails generate scaffold Student instead create everything like this. And then, read these generate code in controller, views, you will understand very deeply!:)
