Christian,
Admin::ResourceController gives you CRUD methods so you don't have to define
them yourself. Methods like :index, :edit, :update, :new, :create, :delete
are built in.
So on a plugin I am working on I only define the show method (controller for a
podcast's Shows) to get a single 'Show' in my podcast...
class Admin::ShowsController < Admin::ResourceController
model_class Show
before_filter :find_model, :only => [ :show ]
def show
respond_to do |format|
format.html # show.html.erb
format.xml { render :xml => @show }
end
end
private
def find_model
@show = Show.find(params[:id]) if params[:id]
end
end
Regards,
-Bill
