Hi all,
I have a model which has a 'report' field. This is an HStoreField, meaning
that it expects key,value pairs. Through the api, an array is submitted. I
have a function, translate_code, which takes each element of that array and
creates a value for it, it should then save the key (code) and the value
(output of translate_code), as part of the HStoreField. I'm trying to
achieve this like so:
class ReportSerializer(serializers.ModelSerializer):
class Meta:
model = Report
fields = "__all__"
def create(self, validated_data):
codes = validated_data.pop("report")
report = {code: translate_code(code) for code in codes}
return Report(**validated_data, report=report)
However, the serializer raises a validation error because it expects a
"dict", not a "list". This is presumably because the validation is called
before the create function. I've tried writing a function called
"validate_report", hoping that this would override validation for the
report field, but it is not called. I've also tried adding validators = []
to the Serializer's Meta class, and writing a 'validate' function, as
suggested by the docs, but this is not called either. It seems as though it
calls the model's validation, but I thought that serializer's did their own
validation, rather than calling their model's clean function?
Thanks in advance for your help!
Alex
