Dajgo Validation error

[Soumen Khatua]

Hi Folk,

What is the process to validate fields in django rest framework?

like email and phone number should be unique and password should be alphanumeric character only.

Where i need to write the logic inside serializers or views part and how i can do that?

Thank you in advance

Regards,

Soumen

For email you can set email field in model as unique=True and the password should be  stored in hash..

seriazlizers.py

    email = serializers.EmailField(required=True,validators=[UniqueValidator(queryset=User.objects.all())])
    phone_number = serializers.CharField(required = True,validators=[UniqueValidator(queryset=User.objects.all())])
    password = serializers.CharField(write_only=True,required=True,
                                        help_text='Leave empty if no change needed',
                                        style={'input_type': 'password', 'placeholder': 'Password'}

                                    ) 

models.py

    email = models.EmailField(_('email address'), unique=True)
    phone_number = models.CharField(max_length=10,unique = True,
                                    blank=False,default = uuid.uuid4().hex[:8])
    first_name = models.CharField(_('first name'), max_length=30)
    last_name = models.CharField(_('last name'), max_length=30, blank=True)
    is_active = models.BooleanField(_('active'), default=True)
    is_staff = models.BooleanField(_('staff status'),default=False)
    date_joined = models.DateTimeField(_('date joined'), default=timezone.now)

  I already did that but I want to raise validation error that email should be unique and password should be alphanumeric character in json format?
