Javascript Django表格'；s下拉列表数据未存储在数据库中

我正在创建一个表单，其中我试图使用for循环从django中的数据库条目中获取选项

但是，我面临一个问题，下拉列表的条目在我的数据库中存储为空白

不确定到底是什么导致了这个问题

这是我试图添加细节的UI端

这是管理面板，我无法在其中保存数据：

下面是我写的代码。 models.py

 class MakeSetup(models.Model):

        make_setup_id = models.IntegerField( primary_key= True)
        make_setup_name = models.CharField(max_length=125, default="NA")
        make_setup_device = models.CharField(max_length=125, default="NA")
        make_setup_consumable = models.CharField(max_length=125, default="NA")
    
    
        def __str__(self):
          return self.make_setup_name
    
        class Meta:
          db_table = "make_setup"


class Device(models.Model):
    device_id = models.IntegerField( primary_key= True)
    device_name = models.CharField(max_length=125 , default="NA")
    device_type = models.CharField(max_length=125 , default="NA")
    
  
    def __str__(self):
      return self.device_name
    
    class Meta:
      db_table = "devices"
