Question

我迁移了错误。请先谢谢我。这是我相关的编码和错误。

migration / 0001_initial_.py

operations = [
        migrations.CreateModel(
            name='Member',
            fields=[
                ('id', models.AutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ID')),
                ('name', models.CharField(max_length=120)),
                ('content', models.TextField()),
            ],
        ),
    ]

models.py

 class Member(models.Model):

    name        = models.CharField(max_length=120)
    content     = models.TextField()

    def __str__(self):
        return self.name`

序列化类

class MembersSerializer(serializers.ModelSerializer):
    class Meta:
        model = Member
        fields = ('id', 'name', 'content')
