model中欄位是

class SampleCurve(models.Model):
    line_id = models.CharField(max_length=128)
    sample_set_id = models.IntegerField()
    result_table_id = models.CharField(max_length=255)
    sample_result_table_id = models.IntegerField()
    group_dimension = models.TextField(blank=True, null=True)
    properties = models.TextField(blank=True, null=True)
    created_by = models.CharField(max_length=50)
    created_at = models.DateTimeField()
    updated_by = models.CharField(max_length=50)
    updated_at = models.DateTimeField()

    class Meta:
        managed = False
        db_table = 'sample_curve'

缺少主鍵，預設是id為主鍵，需要在models.CharField中指定主鍵
