Question

我想知道为什么ActiveAdmin不会通过rails 4中的表单保存记录？当我编辑记录的标题和内容时，我收到消息“已成功更新”，但记录未保存。提前致谢

static_pages.rb

ActiveAdmin.register StaticPage do
  menu false
  config.filters = false

  form do |f|
    f.inputs "Details" do
      f.input :unique_identifier
      f.input :title
      f.input :content, :label => "Content"
    end
    f.actions
  end

end

static_page.rb

class StaticPage < ActiveRecord::Base
  validates_uniqueness_of :unique_identifier
end

迁移

class CreateStaticPages < ActiveRecord::Migration
  def change
    create_table :static_pages do |t|
      t.string :unique_identifier
      t.string :title
      t.text :content
      t.boolean :is_enabled

      t.timestamps
    end
  end
end

Answer 1

我认为不应该将attr_accessible放在您的模型中，而应该尝试将其置于您menu false

正上方的有效管理员static_pages.rb的顶部。

permit_params :unique_identifier, :title, :content

Answer 2

<强>解

通过在模型中添加以下行来解决该问题：

attr_accessible :unique_identifier, :content, :title, :is_enabled

根据Rails 4文档，attr_accessible只在Rails 3中是必需的。因此它看起来更像是activeadmin上的一个bug。
