Different methods to insert data into a database without relying on mongoose

Looking for help implementing the populate() function without using mongoose within the code snippet below:

`

    course.students.forEach(async (student, i) => {
      const s = await Student.findById(student._id);

      console.log(s.toObject()); // successfully retrieves student data

      course.students[i] = s; // encounter issue here
    });

    console.log(course.json());

`

Why does the assignment not work when trying to update the students array with fetched data? Any insights would be appreciated!

Thank you! :)

Answer №1

element, it is important to note that using forEach with await is not recommended. It is suggested to replace it with a for loop and utilize lean() to obtain a plain object from the query:

    for (let i = 0; i < course.students.length; i++) {
      const student = course.students[i];
      course.students[i] = await Student.findById(student._id).lean();
    }

    console.log(course);
