How to delete a specific post from a model in rails?

Since, I am new to rails, so I have want to know a small functionality. I have a reports model in my rails 3 application(not by scaffolding). I am displaying reports one by one through ajax functionality. I want to add a delete link to my each report. I have also created the destroy method in my controller. Now, I don't know how to delete a specific report when I click on the delete link of that particular report. Here's my controller code:-

class ReportsController < ApplicationController
  def index  
    @reports = Report.all(:order => "created_at DESC")  
    respond_to do |format|  
      format.html  
    end  
  end  

  def create  
    @report = Report.create(:description => params[:description])  
    respond_to do |format|  
      if @report.save  
        format.html { redirect_to reports_path }  
        format.js
      else  
        flash[:notice] = "Report failed to save."  
        format.html { redirect_to reports_path }  
      end  
    end  
  end

  def destroy
    @report = Report.find(params[:id])
    if @report.destroy 
      format.html { redirect_to reports_path }  
      format.js         
    end
  end
end

You can assume that my reports are being displayed in the twitter-timeline format and I want to add the delete report feature to each report. Please help me out.

In your view you'd add a link, button, etc. to send the delete action back to the server.

Using link_to for example:

link_to("Destroy", report_path(report), :method => :delete, :confirm => "Are you sure?")

You can do the same with button_to.

Update:

Sorry I missed the AJAX mention (thanks Jeffrey W.).

You'll also want to add :remote => true if you want to send the delete via AJAX.
