python - How can i use additional fields to get jwt token

Question

i use https://django-rest-framework-simplejwt.readthedocs.io/en/latest/

i have such code

User = get_user_model()

class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    bio = models.TextField()
    ROLE_CHOICES = [
        ('U', 'User'),
        ('M', 'Moderator'),
        ('A', 'Admin'),
    ]
    role = models.CharField(max_length=1, choices=ROLE_CHOICES, default='U')
    confirmation_code = models.CharField(max_length=30)

And i want to get JWT token, here is my urls

path("v1/token/", views.EmailTokenObtainPairView.as_view(), name="token_obtain_pair")

i need send such POST query

http://127.0.0.1:8000/api/v1/token/

with data :

{ 'email': email, 'confirmation_code': confirmation_code }

but by default in simple-jwt i need to send data :

{'username' : username, 'password':password }

in my serializer.py

class CustomTokenObtainPairSerializer(TokenObtainPairSerializer):
    username_field = User.EMAIL_FIELD

in my views.py

class EmailTokenObtainPairView(TokenObtainPairView):
    serializer_class = CustomTokenObtainPairSerializer

i have done to chane username on email, bun i can not chane password on confirmation_code

how can i change default way ?

Answer 1

You can override TokenObtainSerializer to customize.

For your case, you need to custom method validate(). Refer to this link https://django-rest-framework-simplejwt.readthedocs.io/en/latest/customizing_token_claims.html and https://github.com/SimpleJWT/django-rest-framework-simplejwt/blob/c684e8396f8446cc289ed73a0740ca222c85470d/rest_framework_simplejwt/serializers.py#L20 for detail.
