我的PostGreSQL数据库中有下表:
workspace_role_id | workspace_role_name
--------------------------------------+---------------------
3f76103f-732a-435a-a88f-737f4a6f1b87 | Owner
c73b7c35-237e-4e13-8269-b259c2858b71 | Admin
a61890fc-1c29-4817-8687-30786a5db17a | User
从此Django模型构建:
class WorkspaceRole(models.Model):
class Meta:
ordering = ("workspace_role_name",)
workspace_role_id = models.UUIDField(primary_key=True, default=uuid.uuid4, blank=True, editable=False)
workspace_role_name = models.CharField(max_length=64, unique=True)
def __repr__(self):
return f"<{self.__class__.__name__}: {self.workspace_role_name}>"
我想从ID中检索workspace_role_name
。
但是
的结果WorkspaceRole.objects.filter(workspace_role_id="a61890fc-1c29-4817-8687-30786a5db17a")
是一个空查询集<QuerySet []>
,但是当我运行
WorkspaceRole.objects.all()
我得到正确的输出:<QuerySet [<WorkspaceRole: Admin>, <WorkspaceRole: Owner>, <WorkspaceRole: User>]>
我的过滤器出了什么问题?

升级您的searching ...
import uuid
id = uuid.UUID('a61890fc-1c29-4817-8687-30786a5db17a')
WorkspaceRole.objects.filter(workspace_role_id=id)

与同事进行一些修补后,解决方案是使用:
with in_database(my_db, write=True):
id = uuid.UUID('a61890fc-1c29-4817-8687-30786a5db17a')
WorkspaceRole.objects.filter(workspace_role_id=id)
