How can I get the objects from this model?

I'm trying to create an address model/views/... that works and I got the model working, but I'm trying to access the data it contains and it's not working. Here is the model:

class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    nick_name = models.CharField('Nick name', max_length=30, blank=True, default='')
    bio = models.TextField(max_length=500, blank=True)
    image = models.ImageField(default='default.jpg', upload_to='profile_pics')
    # Address = models.ForeignKey('Address', on_delete=models.CASCADE)

    # If we don't have this, it's going to say profile object only
    def __str__(self):
        return self.user.username
        #return f'{self.user.username}'  # it's going to print username Profile

    def save(self, *args, **kwargs):
            super().save(*args, **kwargs)

            img = Image.open(self.image.path)

            if img.height > 300 or img.width > 300:
                output_size = (300, 300)
                img.thumbnail(output_size)
                img.save(self.image.path)


class Address(models.Model):
    users = models.ManyToManyField(Profile, blank=True)
    name = models.CharField(max_length=30)
    address = models.CharField(max_length=50)
    city = models.CharField(max_length=60, default="Miami")
    state = models.CharField(max_length=30, default="Florida")
    zipcode = models.CharField(max_length=5, default="33165")
    country = models.CharField(max_length=50)

    class Meta:
        verbose_name_plural = 'Address'

    def __str__(self):
        return self.name

I'm trying to access all the addresses that a user can have. I tried:

# TESTS
allAddresses = Address.objects.all()
print(allAddresses)

and for the address objects it gives me: <QuerySet [<Address: Elizabeth>, <Address: Work>]>

But if I try to filter it by user, like this:

allAddresses = Address.objects.all().filter(users='arturo')
print(allAddresses)

it gives me an error: invalid literal for int() with base 10: 'arturo'

Could someone lead me on the way to get all the addresses of the logged in user please?

Thank you very much!

The filter constraint users refers to the ID of the intermediate many-to-many table, hence the error. You should specify the related fields in full instead, where user refers to the Profile.user field, and username refers to the User.username field:

allAddresses = Address.objects.all().filter(users__user__username='arturo')
