Django query using ManytoManyField

Question

Using example code:

from django.db import models

class Person(models.Model):
    name = models.CharField(max_length=128)

    def __str__(self):
        return self.name

class Group(models.Model):
    name = models.CharField(max_length=128)
    members = models.ManyToManyField(Person, through='Membership')

    def __str__(self):
        return self.name

class Membership(models.Model):
    person = models.ForeignKey(Person, on_delete=models.CASCADE)
    group = models.ForeignKey(Group, on_delete=models.CASCADE)
    date_joined = models.DateField()

How could I get the name of the last 5 persons and their group's name order by date_joined? Something like:

"name1" "group1" "19/02/2019"
"name2" "group1" "19/02/2019"
"name1" "group2" "19/02/2019"
"name3" "group1" "18/02/2019"
"name4" "group2" "17/02/2019"

I have tried many options but I am not able to do it :S Thanks in advance.

You can get this by following

Membership.objects.values('person__name', 'group__name', 'date_joined').order_by(date_joined)[:5]
