通过共享模块使用ActiveAdmin的DSL，包括 [英] Using ActiveAdmin's DSL with shared module includes

问题描述

我正在尝试对在ActiveAdmin中注册的模型进行一些常见/共享的操作。我有以下代码：

I'm trying to make some common/shared actions for my models registered with ActiveAdmin. I have the following code:

# app/admin/concerns/activatable.rb

module Activatable
  def self.included(dsl)
    dsl.member_action :deactivate, method: :put do
      dsl.resource.deactivate!
      redirect_to dsl.resource_path, notice: 'Deactivated.'
    end
  end
end

# app/admin/course.rb

ActiveAdmin.register Course do
  include Activatable
  # ...
end

当我运行 rails服务器时，服务器会抛出以下内容立即退出：

When I run rails server, the server immediately quits having thrown the following:

/Users/Doug/.rvm/gems/ruby-2.1.2/gems/activerecord-4.1.1/lib/active_record/
dynamic_matchers.rb:26:in `method_missing': undefined method `member_action' for
#<Class:0x00000101e79850> (NoMethodError)

DSL似乎不具有与我的<$ c $相同的功能c> course.rb ，其中 activatable.rb 中的代码可以正常工作（尽管没有 dsl。* ）。有什么想法吗？

The DSL doesn't appear to have the same functionality as within my course.rb, where the code from activatable.rb works fine (albeit without the dsl.*). Any ideas?

推荐答案

我已经解决了这个问题-我在 app / models / concerns ，而Rails似乎混淆了这些。我将共享的ActiveAdmin模块重命名为 AdminActivatable ，现在可以访问DSL对象。

I've solved the problem- I had a concern of the same name in my app/models/concerns, and Rails appeared to be muddling these. I renamed my shared ActiveAdmin module to AdminActivatable, and I can now access the DSL object.
