    model = User
    fields = ['email', 'password']

def validate(self, data):

    password = data.get('password', None)

    if not email:
        raise serializers.ValidationError("Please enter email to login.")

    user = User.objects.filter(Q(email=email)).exclude(email__iexact="").exclude(email__isnull=True).distinct()
    if user.exists():
        user1 = authenticate(email=email, password=password)
        if user1 is not None:
            if user1.is_active:
                token, created = Token.objects.get_or_create(user=user1)
                data['token'] = token

        return Response(serializers.data, status=status.HTTP_200_OK)

You can add token field in the your serailizers.

class UserLoginSerializer(serializers.ModelSerializer):
email = serializers.EmailField(
    required=False,
    allow_blank=True,
    write_only=True,
    label="Email "
)

password = serializers.CharField(
    required=True,
    write_only=True,
    style={'input_type': 'password'}
)
token = serializers.SerializerMethodField()

class Meta(object):
    model = User
    fields = ['email', 'password']

def validate(self, data):
    email = data.get('email', None)
    password = data.get('password', None)

    if not email:
        raise serializers.ValidationError("Please enter email to login.")

    user = User.objects.filter(Q(email=email)).exclude(email__iexact="").exclude(email__isnull=True).distinct()
    if user.exists():
        user1 = authenticate(email=email, password=password)
        if user1 is not None:
            if user1.is_active:
                token, created = Token.objects.get_or_create(user=user1)
                data['token'] = token
            else:
                raise serializers.ValidationError("Account not active.")
        else:
            raise serializers.ValidationError("Invalid credentials.")
    else:
        raise serializers.ValidationError("This email is not valid.")


    return data
    def get_token(self, obj):
        try:
            return Token.objects.get(user=obj).key
        except:
            return ''
