✅

as described in documentation
https://www.django-rest-framework.org/api-guide/fields/#serializermethodfield

validation is not working on methodfield because methodfield is read-only field.

My solution

def get_accounts(self, obj):
    if obj.accounts is not None:
        return self.validate_accounts(
            BankAccountSerializer(obj.accounts, many=True).data
        )
    return None

def validate_accounts(self, value):
    """
    Organization should have account with 'is_main' true
    """
    if not value:
        return value
    
    for account in value: # caheck all accounts
        if account["is_main"] == True:
            return value
    raise serializers.ValidationError("Organization should have main account  (is_main=true)")
