When you're filling up a form of a CActiveRecord (using CActiveForm for example), usually you'll construct your code so that in case of validation error you'll get back the form with the error displayed back to you, typically when CActiveForm.errorSummary() is used. This is how its done by Gii.
Sometimes you want to use exisiting translations for locales, which do not directly match.
An example would be a website targeting Germany (de_de), Austria (de_at) and Switzerland (de_ch, fr_ch, it_ch). Although you may have
exisiting translations for German (de), French (fr) and Italian (it), there are problems using it directly.
I like programing on my localhost, however it really bugged me to make changes to index.php & config files on my production server. After combining all available wiki articles on this topic and some trial and error this is what I use for my applications so I could just upload it to production server and it will work without any changes.
Countries sometimes change their laws pertaining to time zones and daylight saving times. This means that GMT+2 can be a different time this August compared to last August! However, by using php's DateTime class (instead of timestamps), we can do both "format" and "time zone" conversions on a single DateTime object (only 2 lines of code) for date, time, timestamp and datetime types - while php takes care of nightmares such as current and historical time zones and daylight saving times.
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”.
