rails一个不错的调试信息输出办法

抄自RailsSpace 113页感觉还不错，收了 <% if ENV["RAILS_ENV"] == "development" %> <div id="debug"> <a href="#" onclick="Element.toggle('params_debug_info');return false">params</a>| <a href="#" onclick="Element.toggle('session_debug_info');return false">session</a>| <a href="#" onclick="Element.toggle('env_debug_info');return false">env</a>| <a href="#" onclick="Element.toggle('request_debug_info');return false">request</a> <fieldset id="params_debug_info" class="debug_info" style="display: none"> <legend>params</legend> <%= debug(params) %> </fieldset> <fieldset id="session_debug_info" class="debug_info" style="display: none"> <legend>session</legend> <%= debug(session) %> </fieldset> <fieldset id="env_debug_info" class="debug_info" style="display: none"> <legend>env</legend> <%= debug(request.env) %> </fieldset> <fieldset id="request_debug_info" class="debug_info" style="display: none"> <legend>request</legend> <%= debug(request) %> </fieldset> </div> <% end %> #debug { margin-top: 1em; margin-left: auto; } #debug a,#debug a.visited { text-decoration: none; color: maroon; } fieldset.debug_info { text-align: left; margin: 1em; background: #eee; }
