AttributeError: 'Seekerskillset' object has no attribute 'skill_name'

Question

I am trying to implement bulk_create my inserting multiple objects in a relation, not sure whether I am doing it right i have added trace back as well below is skill set model

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')

型号

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'

我收到错误

AttributeError: 'Seekerskillset' object has no attribute 'skill_name'

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

Answer 1

问题是由使用 Skillset 批量创建 Seekerskillset 个对象引起的。

所以改变：

seeker_skll = Skillset.objects.bulk_create(seeker_skll)

至：

seeker_skll = Seekerskillset.objects.bulk_create(seeker_skll)

AttributeError: 'Seekerskillset' object has no attribute 'skill_name'
