我正在试图弄清楚为什么我的Rails应用程序不允许我的属性，并且已经没有什么想法了。
我的数据库中有产品（型号Product），它们有一组适用于所有产品的标准属性。我有一个额外的JSONB列，称为dynamic_attributes，它特定于不同类型的产品。因此，我目前使用STI。
如果我试图编辑一个单独的记录，我会得到一个关于不允许的参数（我试图从编辑表单更新/修补的JSON参数）的错误。如果我删除.permit部分并只允许！everywhere，那么我不会得到任何错误，所有内容都会更新，但显然这并不理想。
STI的锁子类

class Lock < Product
  serialize :dynamic_attributes, JsonbSerializers
  store_accessor :dynamic_attributes, :kind, :interface
  validates :kind, presence: true

  def json_schema
    Rails.root.join('app', 'models', 'schemas', 'lock_category.json')
  end
end

它为所讨论的产品类型引用以下JSON模式：

{
  "$schema": "http://json-schema.org/draft-04/schema#",
  "type": "object",
  "required": [ "kind" ],
  "properties": {
    "kind": { 
      "type": "string",
      "enum": ["Cable", "Chain", "Folding", "Frame", "Part", "Padlock", "U-Lock", "U-Lock+Cable"]
    },
    "interface": {
      "type": "string",
      "enum": ["Key", "Combination", "Smart"]
    }
  }
}

产品控制器

def update
    @product = Product.find(params[:id])
    @product.update!(product_params)
    redirect_to @product
  end

private
  
  def product_params
    params.require(:product).
    permit(
      :type,
      :vendor,
      :description,
      :cost,
      :msrp,
      dynamic_attributes: [
        :kind,
        :interface
      ]
    )
  end
end

编辑表单是非常标准的，包含以下用于更新dynamic_attributes的部分：

<% @product[:dynamic_attributes].each do |k,v| %>
    <%= f.label k.to_sym %>  
    <%= f.text_field k.to_sym, :value => v %>
    <br />
  <% end %>

如果让我猜测（此时我所剩下的，我认为它可能是从数据库加载信息到编辑字段，然后再返回之间的事情。
