In my Rails 3 project I have the following code for

1. My controller:

   class TasksController < ApplicationController
   
     def today
       @tasks = Task.today
       @task = Task.new
       respond_to do |format|
         format.html { render :text=> "Sorry , you don't have any task pending today." }
   
         format.html # new.html.erb
         format.xml  { render :xml => @tasks }
       end
     end
   
     def this_week
       @tasks = Task.this_week
       @task = Task.new
       respond_to do |format|
         format.html { render :text => "Sorry , No content for selected period." }
   
         format.html # new.html.erb
         format.xml  { render :xml => @tasks }
       end
     end
   end
   

2. My model:

   class Task < ActiveRecord::Base
   
     def self.today
       Task.where(:due_date => "Date.today" , :task_status => "open").order("due_date ASC")
     end
   
     def self.this_week
       Task.where(:due_date =>"Time.now.this_week" , :task_status => "open" ).order("due_date ASC")
     end
   end
   

Why it does not displaying anything in the relative view. Please help me.

Thanks
