带有 ModelBase 的 Django Formsets 不渲染复选框默认值而是一个下拉列表

Question

如果 no_new_item 存在，我需要创建一个必需的复选框选项。我正在使用 model.NullBoolean 字段。根据 Django 文档，布尔字段应呈现复选框小部件，但 NullBoolean 呈现 Select。之所以改用NullBoolean，是因为迁移时出现null错误。所以现在我得到一个带有 'Yes' 和 'No.' 的下拉列表我将如何使用 NullBoolean 在 Base model.Models 中创建复选框，还是有更好的方法？

（这是我想念的关于 Django 文档的编辑。谢谢@Alasdair）

固定

经过一番思考后，我回到了 model.Base 并将其更改为 BooleanField 类型并添加了默认值。这清除了迁移时的空错误并呈现了一个复选框选项。

class StoreNightlyReportsBase(models.Model):
    store_nightly_report = models.ForeignKey(StoreNightlyReport)
    no_new_item = models.BooleanField(verbose_name="Check if No New Items", default=False)
    customer = models.CharField(verbose_name='Customer Name', max_length=20, null=True)
