#32337: Django Check Constraint is not enforced at all -------------------------------------+------------------------------------- Reporter: | Owner: nobody CosmicReindeer | Type: Bug | Status: new Component: Database | Version: 3.1 layer (models, ORM) | Severity: Normal | Keywords: check constraint Triage Stage: | Has patch: 0 Unreviewed | Needs documentation: 0 | Needs tests: 0 Patch needs improvement: 0 | Easy pickings: 0 UI/UX: 0 | -------------------------------------+------------------------------------- I have a model like this with the following structure. {{{ class Role(BaseModel): class Meta: verbose_name = 'role' verbose_name_plural = 'roles' ordering = ['position', 'cluster'] required_db_features = { 'supports_deferrable_unique_constraints', } constraints = [ models.UniqueConstraint( fields=['position', 'cluster'], name='deferrable_unique_role_position', deferrable=models.Deferrable.DEFERRED ), models.CheckConstraint( name='default_role_check', check=( models.Q(is_default=True, position=1, color='#969696', name='@everyone') | models.Q(is_default=False) ) ), ]
permission_flags = [ 'READ_DATA', 'WRITE_DATA', 'MANAGE_RECORDS', 'MANAGE_ROLES', 'MANAGE_CLUSTER', 'MANAGE_DATASHEETS', 'MANAGE_FIELDS', 'MANAGE_CONSTRAINTS', 'KICK_MEMBERS', 'MANAGE_MEMBERS', ] default_perm_flags = ['READ_DATA', 'WRITE_DATA', 'MANAGE_RECORDS'] def __str__(self): return self.name objects = managers.RolesManager() positions = managers.PositionalManager() permissions = BitField(flags=permission_flags, default=default_perm_flags, db_index=True) position = models.PositiveSmallIntegerField(null=True, blank=True, db_index=True, editable=True) name = models.CharField(max_length=100, validators=[MinLengthValidator(2)], db_index=True, default='new role') color = ColorField(db_index=True, default='#969696') is_default = models.BooleanField(default=False, db_index=True) cluster = models.ForeignKey('api_backend.Cluster', on_delete=models.CASCADE, editable=False) REQUIRED_FIELDS = [name, cluster] }}} Basically I want to ensure that a role with `is_default` set to True should always have a position of 1 and name of '@everyone' and a color of '#969696' However, I am able to edit the model through serializers for the same, and the name changes to something other than '@everyone'. No errors are raised. Same with the position. The constraint isnt enforced for updates or bulkupdates, too. -- Ticket URL: <https://code.djangoproject.com/ticket/32337> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.
