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.

days_left: nil>

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
