Question

This might sound kind of basic (and it probably is), but I’ve been trying to get this for a few hours now and either I need a break from coding or it just wont budge.

I have an active record variable which brings database entries from a model:

$variable = Model::model()->findAll();

So I have $variable available in my view file and I want to check for the existence of a specific entry within the results. I am using the primary key of an entry available in the $variable, but I can’t seem to get it working.

What is the correct way to check if a given entry is contained within that variable from the view file, not the controller?

PS: I do not want to iterate through the result set, it wouldn’t be very efficient for my application.

Thanks.

If I got you right then:

• Indeed its better not to have such pieces of code in a view file.
• If you are forced to use CActiveRecord.fin*() methods, consider using findByPk($pk). If it returns null – no such record.
• Consider having your models extending PcBaseArModel as that class has ‘checkExists($pk)’ method that looks natural in the check you need to perform. This base class has other goodies – check its documentation.
