 Alternatively if you want the errors to be against a specific field, use a dictionary of when instantiating the `ValidationError`, like so:
 
     def validate(self, attrs):
         # serializer.errors == {'my_field': ['A field error']}
-        raise serailizers.ValidationError({'my_field': 'A field error'})
+        raise serializers.ValidationError({'my_field': 'A field error'})
 
 This ensures you can still write validation that compares all the input fields, but that marks the error against a particular field.
