Yii

Its been almost a year since i found something interested to write since im busy working and didn't really get the time to write some useful stuff. Today i came across a well known issue in Yii solution that caused duplicate js request whenever we are doing ajax stuff with renderPartial. Here's a small js script that will save our asses.

        $.ajaxSetup({
                global: true,
                dataFilter: function(data,type){
                        //  only 'text' and 'html' dataType should be filtered
                        if (type && type != "html" && type != "text")
                        {
                                return data;
                        }
         
                        var selector = 'script[src]';
         
                        // get loaded scripts from DOM the first time we execute.
                        if (!$._loadedScripts) 
                        {
                                $._loadedScripts = {};
                                $._dataHolder = $(document.createElement('div'));
 
                                var loadedScripts = $(document).find(selector);
 
                                //fetching scripts from the DOM
                                for (var i = 0, len = loadedScripts.length; i < len; i++) 
                                {
                                        $._loadedScripts[loadedScripts[i].src] = 1;
                                }
                        }
                 
                        //$._dataHolder.html(data) does not work
                        $._dataHolder[0].innerHTML = data;
         
                        // iterate over new scripts and remove if source is already in DOM:
                        var incomingScripts = $($._dataHolder).find(selector);
                        for (var i = 0, len = incomingScripts.length; i < len; i++)
                        {
                                
                                if ($._loadedScripts[incomingScripts[i].src] && incomingScripts[i].src.indexOf('search') == -1)
                                {
                                        $(incomingScripts[i]).remove();
                                }
                                else
                                {
                                        $._loadedScripts[incomingScripts[i].src] = 1;
                                }
                        }
                        return $._dataHolder[0].innerHTML;
                }
        });

Credit goes to Yii forum contributor! but not all scenario will work, still, its good enough at least

Well, i found something interesting yesterday that might be useful for Yii developer when they deal with restful api or JSON output with Yii framework. Sometimes it is good to disable Log output in order to return proper JSON or restful api calls. In that case, you can try to do the following,

        foreach (Yii::app()->log->routes as $route)
        {   
                if ($route instanceof CWebLogRoute || $route instanceof CFileLogRoute || $route instanceof YiiDebugToolbarRoute)
                {   
                        $route->enabled = false;
                }   
        } 

However, if you still seeing your JSON or Restful api output being 'unclean', this is most likely caused by preload options on your config.php file. Preload will always run earlier than whatever you have defined in your action controller. In order to bypass this, the only way is to dive into these extensions and provide certain validation to prevent it from running unnecessary. Sometimes, you will see facebook api appending javascript and meta tag into your json call, in that case, you can add in a new 'enabled' property on your facebook extension and disabled upon your action controller initialization. You can place the following code below to shut up facebook entirely upon running your action controller method.

Yii::app()->facebook->enabled = false;

the enabled property have to be written by you as a new property on facebook extension class file. And the other condition to prevent certain method to run will also have to be written by you since Yii doesn't provide a more graceful method to disable output before preload or extensions that are not managed by them
