ActionController :: UnknownFormat（ActionController :: UnknownFormat）

Question

好吧，我正在尝试从数据库更新一些注册表，但它不断提高unknownFormat错误，你们看到我错过了什么？

它有点基本，但我觉得我在这里缺少一些非常重要的东西

 @contributor = Contributor.find(params[:format])

    respond_to do |format|
      if @contributor.company.users.include?(current_user) && @contributor.company.contributors.find_by(user_id: current_user.id).manager? && @contributor.update(manager?: false)
        collaborator = Contributor.where(company_id: @contributor.company.id, user_id: current_user.id).first
        if Notification.create(notifiable: collaborator, action: "Você não é mais dono(a)", user_id: @contributor.user.id)
          format.html { redirect_to companies_path, notice: 'Você retirou esta pessoa de dono(a)' }
          format.json { head :no_content}
        end
      else
        # format.html { redirect_to companies_path }
        format.json { render json: @contributor.errors, status: :unprocessable_entity }
      end
    end

如你所见，它会在错误发生前创造出来，所以我认为这只是retunr的一个问题

format.html format.json

你问我这个参数，我觉得发布这两个表的模式会很好

  create_table "contributors", force: :cascade do |t|
    t.integer "company_id"
    t.integer "user_id"
    t.boolean "manager?", default: false
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
    t.index ["company_id"], name: "index_contributors_on_company_id"
    t.index ["user_id"], name: "index_contributors_on_user_id"
  end

-----------------
  create_table "notifications", force: :cascade do |t|
    t.string "notifiable_type"
    t.integer "notifiable_id"
    t.integer "user_id"
    t.string "action"
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
    t.datetime "read_at"
    t.index ["notifiable_type", "notifiable_id"], name: "index_notifications_on_notifiable_type_and_notifiable_id"
    t.index ["user_id"], name: "index_notifications_on_user_id"
  end

和模型

class Contributor < ApplicationRecord
  belongs_to :company
  belongs_to :user

  has_many :notifications, as: :notifiable
end

class Notification < ApplicationRecord
      belongs_to :notifiable, polymorphic: true
      belongs_to :user
end

respond_to do |format|
  if @contributor.company.users.include?(current_user) && @contributor.company.contributors.find_by(user_id: current_user.id).manager? && @contributor.update(manager?: false)
    collaborator = Contributor.where(company_id: @contributor.company.id, user_id: current_user.id).first
    if Notification.create(notifiable: collaborator, action: "Você não é mais dono(a)", user_id: @contributor.user.id)
      format.html { redirect_to companies_path, notice: 'Você retirou esta pessoa de dono(a)' }
      format.json { head :no_content}
    end
  else
    format.html { redirect_to companies_path }
    format.json { render json: @contributor.errors, status: :unprocessable_entity }
