rendering a response in rails

   respond_to do |format|
      if @begger.save
        format.html { redirect_to(@begger, :notice => 'Begger was successfully created.') }
        format.xml  { render :xml => @begger, :status => :created, :location => @begger }
      else
        format.html { render :action => "new" }
        format.xml  { render :xml => @begger.errors, :status => :unprocessable_entity }
      end
    end

The render method takes several options for its first argument: :text, :nothing, :inline, :template,
:action, :xml, :json, :js, and :update.
