Sure I’m missing out something or not thinking about a better way to accomplish what I need, but here is what I want to do.

I have three models: A, B and C. A has a relation MANY-MANY with B called relation1, and Bhas a relation MANY-MANY with C, called relation2. I want to get all B records with their C relations (eager loading), but just from an A instance (lazy loading, because I don’t want to waste memory loading all relation1 instances).

So, what I want to do should be something like the following:

A::model()->findByPk($somePrimaryKey)->relation1->with('relation2');

Of course that’s not working because using relation1 lazy loading I’m getting an array of instances and then I’m tryng to apply the with() method to a non-object.

Sure I can do a little bit of work around iterating through the array, but I want to know if there is a quick and elegent way 🙂

Thank you!

    You can try this: 

    A::model()->findByPk($somePrimaryKey)->with('relation1.relation2');

    I cant find any sense in that you “don’t want to waste memory loading all relation1 instances”

    This way you are just loading the B models that relate to that specific A model. not all of them.

    Also take a look at Relational Query with through
