嘿，我试图通过表单中的复选框集合填充多对多关联。但是，结果总是以空字符串开头

= simple_form_for([:companies, @view_model.sales_price]) do |f|
  = f.input :name, autofocus: true
  = f.input :margin_percentage
  = f.association :carrier_products, as: :check_boxes, include_hidden: false

结果

[..., ..., ""]

我传入了

include\u hidden

标记，但它没有帮助

有什么建议吗
