Initializing drf Serializer - django

Question

I have two models: User and Employee. I want to return following json via drf:
[ { 'admin': {}, 'employee': [{}, {}] }, { 'admin': {}, 'employee': [{}, {}] } ].
However, I don't understand how to initialize a TeamSerializer with data. What should I pass into TeamSerializer
class Meta:
model = User
fields = [
"first_name",
"last_name",
"email",
"hourly_rate",
"role",
]
class EmployeeSerializer(serializers.ModelSerializer):
class Meta:
model = Employee
fields = [
"first_name",
"last_name",
"email",
"hourly_rate",
"role",
]
class TeamSerializer(serializers.Serializer):
admin = AdminSerializer()
employee = EmployeeSerializer()

Answer 1

You will need to create a model for team to specify the relation.
If I understand right, each team has an admin and multiple employees, each employee can be member of one team, and an admin can administer one team. so one to one relation for admin and one to many relation for employee.
The model should look like this:
class Team(models.Model):
admin = models.OneToOneField(get_user_model(), on_delete=models.SET_NULL, null=True)
class Employee(models.Model):
user = models.OneToOneField(get_user_model(), on_delete=models.CASCADE)
team = models.ForeignKey(Team, on_delete=models.CASCADE, related_name="employees")
# all the rest of your fields here
Then create a serializer for Team:
class TeamSerializer(serializers.ModelSerializer):
admin = UserSerializer()
employees = EmployeeSerializer()
class Meta:
model = Team
fields = ["admin", "employees"]
I would take that even farder and create a Admin model and AdminSerializer also to provide more information about the admin, but it depends on your needs.
