Changing the way a CGridView is rendered from the configuration file, or through behaviors specified at the moment it is used, is handy to extend a CGridView without creating tons of different classes for it.

I like programing on my localhost, however it really bugged me to make changes to index.php & config files on my production server.

Yii ‘s CArrayDataProvider is very helpful to display model relation data's directly on it.But it is truely a confusing one because by default it will assume a table field named “id” as primary key for its pagination purpose and what if you dont have field named “id” as primary key on your table? so its truely confusing and if you tried to display without an “id” field on ur table you will get an error like “yourmodel.id is not defined”.
Say, you want to write a test for a component which provides a caching feature. How would you know, that some method of your component returns a cached result? With the solution described here you can inspect all log outputs. So you could search the logs for accesses to the DB to really make sure, that the result was served from cache.
