我正在尝试通过活动管理面板创建一条新的图书记录，但点击“创建”按钮后却无法创建。点击“创建”按钮后，会有一个包含表单数据的 POST 请求发送到 /admin/books。但它并没有返回 302 错误并重定向到图书列表，而是返回了 200 错误以及类似更新表单的内容。即使我打开控制台检查图书是否已创建，它仍然没有创建。我手动在模型中添加了“新建”和“创建”操作，现在一切正常。创建操作在其他模型中运行正常，并且只影响我的“图书”模型。

这是我的 admin/books.rb 文件中的代码

ActiveAdmin.register Book do
  permit_params :title, :page_count, :book_type, :year_released, :price, :genre_id, :language_id, :author_id

  # Displays the drop down menus correctly as well as all other inputs in order of my choosing
  form do |show|
    show.inputs "Details" do
      show.input :language_id, as: :select, collection: Language.all.collect { |language|
      [ language.language_short, language.id ] }
      show.input :author_id, as: :select, collection: Author.all.collect { |author| [ author.full_name, author.age,
      author.gender_short, author.biography, author.id ] }
      show.input :title
      show.input :genre_id, as: :select, collection: Genre.all.collect { |genre| [ genre.genre, genre.id ] }
      show.input :book_type
      show.input :year_released
      show.input :price
    end

    show.actions
  end
end

这是我的书籍模型

class Book < ApplicationRecord
  # Validates that all columns are not empty
  validates :title, :page_count, :book_type, :year_released, :price, presence: true
  # Validates that the title is unique
  validates :title, uniqueness: true
  # Associations between its parent tables and child table
  # has_and_belongs_to_many :genres
  belongs_to :language
  belongs_to :author
  has_many :purchases

  def self.ransackable_associations(auth_object = nil)
    [ "author", "genres", "language", "purchases" ]
  end

  def self.ransackable_attributes(auth_object = nil)
    [ "author_id", "book_type", "created_at", "genre_id", "id", "language_id", "page_count", "price", "title", "updated_at", "year_released" ]
  end
end

当我使用默认的书籍表单而不是自定义表单时，genre_id 属性不会出现，并且仍然执行相同的行为（无法创建书籍并返回 POST 200）。

我正在使用 Ruby 版本 3.4.1 和 Rails 版本 8.0.2。

这些是创建新书籍时的服务器日志
