How to embed MongoDB documents in Symfony 3.4

Question

I´m new in Symfony 3.4 and I am try to embed a document into another document, like this:

{ name:"alex", age: 18, schoolGrades:{ elementary: "yes", highScholl: "yes", college: "no" } }

I´m using Doctrine ODM to work this, but I don´t know how I can do this.

Answer 1

There's a concept of Embedded documents that does exactly that:

/** @Document */
class Student
{
  /** @EmbedOne(targetDocument="SchoolGrades") */
  private $schoolGrades;
}

/** @EmbeddedDocument */
class SchoolGrades
{
}
