Re: 3.x - where and null

No, I think we forgot to include it in the book. Would you be kind to do that as well? :)

It's not really documented is it ? (or maybe i'm just blind ?) (The IS operator that is)

Nope, it was added after I created the TreeBehavior. Do you have time to submit a PR for changing that?

ok, because i can see in TreeBehavior you do something like this

->where(function($exp) use ($parentId, $parent) {
   return $parentId === null ? $exp->isNull($parent) : $exp->eq($parent, $parentId);
})

Is there a downside to using IS ?

->where(['parent_id IS' => $parent_id])

It will convert to NULL if needed or just use the provided value

Hey

in 2.x you could do something like this:

'conditions' => array('parent_id' => $parent_id);

where $parent_id could be an int or null

and it would find parent_id that were null in the table

This approach does not work in 3.x. Is there a right way to do this in 3.x where a field in an INT but can be null ?
