AttributeError：“Seekerskillset”对象没有属性“skill_name”

Question

我正在尝试实现在关系中插入多个对象的bulk_create，不确定我是否做对了--我在下面添加了跟踪--这是技能集模型

class Skillset(models.Model):
    skill_name = models.CharField(max_length=255)

    def __str__(self):
        return self.skill_name

我的观点

skill_name = request.POST.getlist('skill_name')
        skill_level = request.POST.getlist('skill_level')
        print(f'skill name-> {skill_name} skill level ->{skill_level}')
        seeker_skll = []
        # testing destructing
        for skill_nme, skill_lvl in zip(skill_name, skill_level):
            skill_set = Skillset.objects.get(skill_name=skill_nme)
            seeker_skll.append(Seekerskillset(
                skill_set=skill_set, skill_level=skill_lvl, seeker=user))

        seeker_skll = Skillset.objects.bulk_create(seeker_skll)
        print(seeker_skll)
        return redirect('/users/dashboard')

模型

class Seekerskillset(models.Model):
    skill_set = models.ForeignKey(Skillset, on_delete=models.CASCADE)
    seeker = models.ForeignKey(SeekerProfile, on_delete=models.CASCADE)
    skill_level = models.CharField(max_length=25)

    class Meta:
        verbose_name = 'Seeker skill set'

错误--我得到了

AttributeError：“Seekerskillset”对象没有属性“skill_name”

Exception Type: AttributeError at /users/app_det/
Exception Value: 'Seekerskillset' object has no attribute 'skill_name'

Answer 1

该问题是由于使用Skillset批量创建Seekerskillset对象造成的。

因此，改变：

seeker_skll = Skillset.objects.bulk_create(seeker_skll)

至：

seeker_skll = Seekerskillset.objects.bulk_create(seeker_skll)
