Question

这似乎应该相对简单一些，但是在跟踪答案时遇到了一些麻烦：

如何在ActiveAdmin中设置页面标题？

Answer 1

合并答案并添加一些内容：

其中大多数在this page on the wiki上（或者我会尽快放在那里）。

在为activeadmin注册模型的文件中（例如app / admin / user.rb），您可以

ActiveAdmin.register User do
  # a simple string
  index :title => "Here's a list of users" do
    ...
  end

  # using a method called on the instance of the model
  show :title => :name do
    ...
  end

  # more flexibly using information from the model instance
  show :title => proc {|user| "Details for "+user.name } do
    ...
  end

  # for new, edit, and delete you have to do it differently
  controller do
    def edit
      # use resource.some_method to access information about what you're editing
      @page_title = "Hey, edit this user called "+resource.name
    end
  end
end
