.d.ts文件中的“预期类型”

Question

有人可以解释为什么会失败，以及如何纠正它？

class Article
  include Mongoid::Document
  field :title, type: String
  field :body, type: String
  has_and_belongs_to_many :categories

  def category_articles
    output = []
    categories.each do |cat|
      output << cat.articles.pluck(:title)
    end
    return output.flatten.join(', ')
  end

  rails_admin do
    list do
      include_all_fields
      field :category_articles
    end
  end
end

似乎函数参数可以接受文字值，但不能作为函数参数中对象字段的限制。最好的方法是什么？

hitType：＆＃39; event＆＃39;，

这需要对字符串联合的支持虽然已添加到TypeScript最新版本尚未作为稳定版本发布，因此绝对类型的架构不支持它。
