We are using Django for Speedy Net and Speedy Match (currently Django 1.11.18, we can't upgrade to a newer version of Django because of one of our requirements, django-modeltranslation). I want to validate each model before saving it to the database, so I'm using class ValidateModelMixin
as the base of each model.
For this reason, I want to disable bulk_create
in all managers in all of our models. So I added this code:
class ValidateModelMixin(object): def save(self, *args, **kwargs): """Call `full_clean` before saving.""" self.full_clean() return super().save(*args, **kwargs) class ManagerMixin(object): def bulk_create(self, *args, **kwargs): raise NotImplementedError("bulk_create is not implemented.") class BaseModel(ValidateModelMixin, models.Model): def save(self, *args, **kwargs): try: field = self._meta.get_field('id') if ((not (self.id)) and (hasattr(field, 'id_generator'))): self.id = field.id_generator() while (self._meta.model.objects.filter(id=self.id).exists()): self.id = field.id_generator() except FieldDoesNotExist: pass return super().save(*args, **kwargs) class Meta: abstract = True class TimeStampedModel(BaseModel): date_created = models.DateTimeField(auto_now_add=True, db_index=True) date_updated = models.DateTimeField(auto_now=True, db_index=True) class Meta: abstract = True class BaseManager(ManagerMixin, models.Manager): pass class BaseUserManager(ManagerMixin, DjangoBaseUserManager): pass
I thought maybe it's good to add these settings - disable bulk_create
in all managers and call self.full_clean()
before saving the models - as an optional settings both in the project and also in each model (maybe in class Meta
) so it will be possible to override Django's default both per-project and also for any specific model. I understand that the default is not to call self.full_clean()
before saving the models and to allow bulk_create
in the managers, but I suspect this may lead to invalid data in the database of the projects.
The current code in the master is on https://github.com/speedy-net/speedy-net/blob/master/speedy/core/base/models.py, and the code in the branch I'm currently working on is on https://github.com/speedy-net/speedy-net/blob/uri_merge_with_master_2019-01-05_a/speedy/core/base/models.py.
