Comment (by Андрей):
The error falls from serializer.is_valid (it is
rest_framework.exceptions.ValidationError):
>>> from directories.views import MyModelViewSet
>>> viewset = MyModelViewSet()
>>> new_object = viewset.create(data={'name': 'test', 'measure': 1})
Traceback (most recent call last):
File "<console>", line 1, in <module>
File "....views.py", line 15, in create
serializer.is_valid(raise_exception=True)
File "....venv\Lib\site-packages\rest_framework\serializers.py", line
231, in is_valid
raise ValidationError(self.errors)
rest_framework.exceptions.ValidationError: {'name':
[ErrorDetail(string='my model with this Name already exists.',
code='unique')]}
