django - 如何使 Wagtail Streamfield 不需要？

Question

在下面的模型中，我想制作 bottom_content不需要整个字段。我怎样才能做到这一点？

class ServicePage(Page):
  top_content = StreamField(default_blocks + [
    ('two_columns', TwoColumnBlock()),
    ('three_columns', ThreeColumnBlock()),
  ])
  bottom_content = StreamField(default_blocks + [
    ('two_columns', TwoColumnBlock()),
    ('three_columns', ThreeColumnBlock()),
  ])

  search_fields = Page.search_fields + [
    index.SearchField('top_content'),
    index.SearchField('bottom_content'),
  ]

  content_panels = Page.content_panels + [
    StreamFieldPanel('top_content'),
    StreamFieldPanel('bottom_content'),
    InlinePanel('service_package', label='Packages')
  ]

StreamField 还接受一个可选的关键字参数空白，默认为 false；如果这是错误的，则必须至少提供一个块才能将该字段视为有效。
