render and redirect_to

render 作为渲染页返回，  redirect_to则完全跳转。

render :text => '邮件已发送成功'

render :text => "请至少选择一条记录进行操作！<a href='/actives/#{params[:cad_active_id]}'>请返回操作</a>",:layout=>"part_cad"

render :template=>"rcrm_meetings/send_invite_emails.html.erb"

render :partial=>"/cad_contacts/showsearch"

render :layout=>"part_cad"

redirect_to(:controller=>"add_contact",:cad_active_id=>params[:cad_active_id])
