在Django Admin面板中只显示一个字段？

Question

我在admin Django文件中声明了以下两个类。在管理面板上显示了3个内联输入，我只想显示1个输入。有关为什么显示3个内联输入而不仅仅是一个的猜测？

class OriginURLInline(ViewPermissionMixin, admin.StackedInline):
model=IncentiveReferrerURL
verbose_name = 'Promotion URL'
verbose_name_plural = 'Promotion link'
fields = ('origin_url',)

class IncentiveReferrerURL(TimeStampedModel):
# The TimeStampedModel will provide self-updating 'created' and 'modified' fields on the inherited model

incentive = models.ForeignKey(
    Incentive,
    on_delete=models.PROTECT,
    null=True,
    blank=True,
)
origin_url = models.CharField(
    max_length = 100,
    verbose_name = 'Promotion Name:',
    help_text='Please e'
)
