如何修改从表Category表中的parent_project对应从表的need_create_file字段的值？
class Category(models.Model):
id = models.UUIDField(auto_created=True,default=uuid.uuid1,primary_key=True,editable=False,db_index=True,blank=False,unique=True,verbose_name='分类主键',help_text='分类主键')
name = models.CharField(max_length=200,blank=False,verbose_name='组件名',help_text='组件名')
desc = models.CharField(max_length=200,blank=True,verbose_name='组件描述',help_text='组件描述')
category_type = models.IntegerField(choices=settings.CATEGORY_TYPE,verbose_name='组件级别',help_text='组件级别')
status = models.IntegerField(default=0,verbose_name='组件状态',help_text='组件状态')
create_time = models.DateTimeField(verbose_name='创建时间',default=datetime.now,help_text='创建时间')
create_user = models.ForeignKey(User,null=True,blank=True,related_name='category_create_user',help_text='创建用户',verbose_name='创建用户',on_delete=models.SET_NULL)
attorn_time = models.DateTimeField(verbose_name='修改时间',default=datetime.now,help_text='修改时间')
attorn_user = models.ForeignKey(User,null=True,blank=True,related_name='category_attorn_user',help_text='修改用户',verbose_name='修改用户',on_delete=models.SET_NULL)
parent_category = models.ForeignKey('self',null=True,blank=True,default=None,db_index=True,help_text='所属模块',verbose_name='所属模块',related_name='child',on_delete=CASCADE)
parent_project = models.ForeignKey(ProjectAuto,null=True,blank=True,db_index=True,default=None,help_text='归属项目',verbose_name='归属项目',to_field='auto_id')
class ProjectAuto(models.Model):
"""
脚本执行
"""
auto_id = models.UUIDField(auto_created=True,default=uuid.uuid1,primary_key=True,db_index=True,blank=False,unique=True,verbose_name='项目主键',help_text='项目主键')
实现方法：
cate_obj=Category.objects.filter(pk=category_id).first()
category_ = category_obj.parent_category.parent_project
category_.need_create_file=True
category_.save()
