Django 表单 - 将布尔字段更新为 true

Question

我正在尝试更新一个布尔字段，但我遇到了这个问题：save() 得到了一个意外的关键字参数“update_fields”。

我遇到了不同的问题：一开始，当卖家填写表格时，它正在创建一个新渠道。我只想更新当前频道。

Logic= 消费者与卖家创建一个渠道（渠道不活跃）-> 如果卖家想要启动它。他有一种形式可以使它成为现实并启动它。

型号：

class Sugargroup(models.Model):
    consumer = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name="sugargroup_consumer", blank=True, null=True)
    seller = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name="sugargroup_seller")
    is_active = models.BooleanField('Make it happen', default=False)
    slug = models.SlugField(editable=False, unique=True)

试试这个：

validation_form.is_active = True
validation_form.save()
