validator not working in serializers.ModelSerializer

[Maurya Allimuthu]

Hi All,

I use  serializers.ModelSerializer and viewset DetailViewset(APIView).

The validators are not getting called on GET request of the viewset via URLS, but the GET request is working.

def validate(self, attrs):
    if attrs.get('password') != attrs.get('confirm_password'):
        raise serializers.ValidationError("Those passwords don't match.")
    return attrs

OR

class Meta:
    model = *********
    fields = ('***', )
    validators = [
        trigger_validator
    ]

Thanks,

Maurya

Hi,

Validators are only called when you are updating something on the model - a get request doesn't update anything and the validators will not be called (there is no data sent to the server to validate). The validators will be called on a POST, PUT or PATCH request.

Regards,

Andréas

Hi Andreas Kuhne,

Thanks on the quick answer and great help. :-)

Hi Andreas Kuhne/All,

Is there a way or any kind of approach, I can use validators/anything in GET method to format/change the output of the data coming from database and before getting changed by serializer as stream of strings.

Please let me know if any.

Regards,

Maurya

If you want to change the output, you can override the fields that you output in your serializer. That's what the fields are for?

I think it would be helpful if you provide more information because at least I don't really understand your use-case. 

The way I would do it is to change the fields and format them the way I wanted them to be on a get request.

Regards,

Andréas

Many thanks Andreas :-)

Hi  Andréas,

I have fixed it. like subclassing the serializer field class and overriding the to_representation for per field.

Thanks for the help once again.

Thanks,

Maurya
