+    # ActionORM is a class to be implemented by each ORM to allow Rails to
+    # generate customized controller code.
+    #
+    # The API has the same methods as ActiveRecord, but each method returns a
+    # string that matches the ORM API.
+    #
+    # For example:
+    #
+    #   ActiveRecord::Generators::ActionORM.find(Foo, "params[:id]")
+    #   #=> "Foo.find(params[:id])"
+    #
+    #   Datamapper::Generators::ActionORM.find(Foo, "params[:id]")
+    #   #=> "Foo.get(params[:id])"
+    #
+    # On initialization, the ActionORM accepts the instance name that will
+    # receive the calls:
+    #
+    #   builder = ActiveRecord::Generators::ActionORM.new "@foo"
+    #   builder.save #=> "@foo.save"
+    #
+    # The only exception in ActionORM for ActiveRecord is the use of self.build
+    # instead of self.new.
+    #
+    class ActionORM
+      attr_reader :name
+
+      def initialize(name)
+        @name = name
+      end
+
+      # GET index
+      def self.all(klass)
+        raise NotImplementedError
+      end
+
+      # GET show
+      # GET edit
+      # PUT update
+      # DELETE destroy
+      def self.find(klass, params)
+        raise NotImplementedError
+      end
+
+      # GET new
+      # POST create
+      def self.build(klass, params=nil)
+        raise NotImplementedError
