Django serializer data - django

Question

I need to get value of basket in 'title' not in 'id'.
How can I do this? How can I get a value of 'title' from 'Position' model in another 'Client' model using ManyToManyField. It automatically transmits ID and the 'title' is required
I have tried many ways but... It must be easy, but i search info 2 days
class Position(models.Model):
title = models.CharField(max_length=150, verbose_name='Title')
slug = models.SlugField(max_length=100, unique=True, db_index=True, verbose_name='URL')
description = models.CharField(max_length=500, verbose_name='Describe')
photo = models.ImageField(upload_to="photos/%Y/%m/", verbose_name='Photo', null=True)
price = models.DecimalField(decimal_places=2, max_digits=10, verbose_name='Price')
date_create = models.DateTimeField(auto_now_add=True, verbose_name='Date create')
date_update = models.DateTimeField(auto_now=True, verbose_name='Date update')
is_published = models.BooleanField(default=True, verbose_name='Is published')
in_stock = models.BooleanField(default=True, verbose_name='In stock')
class Client(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
basket = models.ManyToManyField('Position', default=None, blank=True, related_name='basket')
def __str__(self):
return f'{self.user.username}, id-{self.user.id}'
class ClientSerializer(serializers.ModelSerializer):
class Meta:
model = Client
fields = "__all__"
class ClientViewSet(viewsets.ModelViewSet):
serializer_class = ClientSerializer
permission_classes = (IsOwnerOrReadOnly,)
def get_queryset(self):
pk = self.kwargs.get('pk')
# need a list of objects, not an one
return Client.objects.filter(pk=pk)
result:
{
"id": 1,
"user": 1,
"basket": [
1
]
}
need something like this - "basket":['monitor','keyboard']

You can use the PositionSerializer to get the title of each Position object in the Client's basket ManyToManyField.
class PositionSerializer(serializers.ModelSerializer):
class Meta:
model = Position
fields = ('title',)
class ClientSerializer(serializers.ModelSerializer):
basket = PositionSerializer(many=True, read_only=True)
class Meta:
model = Client
fields = "__all__"
