How to rename ForeignKey set field in Django Rest Framework

Question

I am serializing Foreign key set using Django Rest Framework, I have following models:

class Transaction(models.Model):
    ...
class TransactionStatus(models.Model):
    transaction = models.ForeignKey(Transaction)
    ...

I have a serializer for both of these models, one of them looks like this:

class TransactionSerializer(serializers.ModelSerializer):
    transactionstatus_set = TransactionStatusSerializer(many=True, read_only=True)

    class Meta:
        model = Transaction
        depth = 1
        fields = ('id', 'transactionstatus_set')

I want to have here a list of transaction statuses from back referenced _set queryset... But transaction_set just seems very awkward name in API for that..

Answer 1

After a quick experimenting I have discovered that this will do the trick:

class TransactionSerializer(serializers.ModelSerializer):
    changes = TransactionStatusSerializer(many=True, read_only=True, source='transactionstatus_set')

    class Meta:
        model = Transaction
        depth = 1
        fields = ('id', 'changes')

Now I have a list of the statuses linked by foreign key with a nice name...
