access json data from rails controller in ajax call and process it

I am building a Task Management System and have implemented
fullcalendar.js in it. I need to get the pending tasks and change the
color of those pending tasks. I am getting the instance variable of
pending tasks details in the rails controller. But in the ajax request I
am not able to loop it.

Please find my code below.

      $(''.task_name'').live(''click'', function
() {
        alert(this.id);
        $.ajax({
            url: ''pending_task_details'',
            data: {
                task_id: this.id
            },
            success: function (data, response, event, date) { <%
                for date_cell in
@pending_tasks.start_date..@pending_tasks.end_date %>
getCellFromDate(date_cell, calInstance); <% end %>
            }
        });
    });

The above is the logic I need to implement. But I am not getting
@pending_tasks.start_date in the view.

In the console I am getting the tasks details
#<Task id: 4, project_id: 4, task_name: \"Task4\", task_type: nil,
user_id: 2, description: \"Description4\", pm_id: nil, created_at:
\"2012-11-01 09:42:37\", updated_at: \"2012-11-01
09:42:37\",
percent_completed: \"12\", status: \"completed\", due_date:
nil,
start_date: \"2012-11-01\", end_date: \"2012-11-08\",
priority: \"low\",
days_left: nil>

In the tasks controller I am getting the pending tasks as.

      def pending_task_details
        @pending_tasks = Task.find_by_id(params[:task_id])
        p "The pending tasks are......",@pending_tasks.inspect
   
#(Date.parse(@pending_tasks.start_date.to_s)..Date.parse(@pending_tasks.end_date.to_s)).each
{ |date| render :json=>[date.strftime(''%a %d %b %Y'')] and
return}
        render :json=>@pending_tasks
      end

you simply can''t do this. try

$.ajax({
  url: ''pending_task_details'',
  data: { task_id: this.id },
  dataType: ''json'',
  success: function(data) {
    // do something USING javascript with data here. don''t use ruby
    data.map(function(d) {
      return d.dates.each(function(date) { return
getCellFromDate(data[0].date, calInstance) });
    });
  }
})

something like this. i''m pretty sure this still has some errors but you
should be able to work with that.
just remember to add a dates key with the range of date when you render
json.

Creating associations via scaffolding?

Hey guys… beginner question here so hopefully it''s an easy and quick
answer.

Is it possible to create associations via scaffolding? Say I have an Artists
model and a Song model and I want song to have an artist_id. Can I create that
via the scaffold command? Or would I scaffold like normal for both Artist an
Song and the add in the column and index for artist_id to Song?

Thanks
Dan
