My question was: How can I improve this detailed view of a contributor?
# serializers.py
class ContributorDetailSerializer(serializers.ModelSerializer):
class Meta:
model = Contributor
fields = ["id", "user"]
result in Postman:
My contributor model has just one attribute: user a ForeignKey relation to the user model.
# models.py
class User(AbstractUser):
pass
def __str__(self):
return self.username
class Contributor(models.Model):
user = models.ForeignKey(
"api.User",
on_delete=models.CASCADE,
related_name="users",
verbose_name=_("user"),
)
def __str__(self):
return self.user.username
There are several possibilities, I want to show two different approaches:
first example:
using the __str__ method of the user model
# serializers.py
class ContributorDetailSerializer(serializers.ModelSerializer):
user = serializers.StringRelatedField()
class Meta:
model = Contributor
fields = ["id", "user"]
result in Postman:
user = serializers.StringRelatedField() is displaying the __str__ method of the user model. As you can see above in the __str__ method in user model, it returns the username of the user.
second example
display all information of an other Serializer
# serializers.py
class ContributorDetailSerializer(serializers.ModelSerializer):
user = UserSerializer(read_only=True)
class Meta:
model = Contributor
fields = ["id", "user"]
result in Postman:
user = UserSerializer(read_only=True) takes all the attributes of UserSerializer and adds them to the ContributorSerializer attribute user and display all information.
