This code seems to be duplicated across your project.
Duplicated code is one of the most pungent code smells. If you need to duplicate the same code in three or more different places, we strongly encourage you to look into extracting the code into a single class or operation. You can also find more detailed suggestions in the “Code” section of your repository.

It seems like
populateRelation() must be provided by classes using this trait. How about adding it as abstract method to this trait?
This check looks for methods that are used by a trait but not required by it. To illustrate, let’s look at the following code example trait Idable {
public function equalIds(Idable $other) {
return $this->getId() === $other->getId();

This check looks for methods that are used by a trait but not required by it.
To illustrate, let’s look at the following code example
The trait
Idable
provides a methodequalsId
that in turn relies on the methodgetId()
. If this method does not exist on a class mixing in this trait, the method will fail.Adding the
getId()
as an abstract method to the trait will make sure it is available.
