ruby-on-rails - 如何删除删除选项表单 activeAdmin？

Question

在 rails gem active admin 我想从 default_actions 中删除删除选项，而我仍然需要编辑和显示操作，有什么办法吗？

Answer 1

您添加actions对每个 Active Admin 资源的调用：

ActiveAdmin.register Foobar do
  actions :all, :except => [:destroy]
end

Answer 2

在某些时候我遇到了这个问题，因为销毁方法，“删除”按钮没有消失

actions :all, except: [:destroy]

controller do
  def destroy # => Because of this the 'Delete' button was still there
    @user = User.find_by_slug(params[:id])
    super
  end    
end

Answer 3

接受的答案引发了一个异常，“参数数量错误”所以我这样做是为了排除删除按钮（：destroy action）

ActiveAdmin.register YourModel do
  actions :index, :show, :new, :create, :update, :edit

   index do

     selectable_column
     id_column
     column :title
     column :email
     column :name

    actions 
   end

Answer 4

Another way to remove actions from default_actions for an ActiveAdmin resource is via config variable, like:

    ActiveAdmin.register MyUser do
      config.remove_action_item(:destroy)
      ...
    end

One way is already mentioned in the accepted answer via actions method.

Answer 5

如果要完全删除删除销毁按钮，请使用：

actions :all, except: [:destroy]

但是如果删除按钮需要基于资源属性的条件（例如关联数据或状态）。

在索引页面：

index do

  # ...

  actions defaults: false do |row|
    if can? :read, row
      text_node link_to "View", admin_resource_path(row), class: "view_link"
    end
    if can? :edit, row
      text_node link_to "Edit", admin_resource_path(row), class: "edit_link"
    end
    if can? :destroy, row
      text_node link_to I18n.t('active_admin.delete'), admin_resource_path(row), method: :delete, data: { confirm: I18n.t('active_admin.delete_confirmation') }, class: "delete_link" if row.deletable?
    end
  end
end

现在是复杂的部分，我不得不敲了几次头才能在显示页面上控制它：

config.remove_action_item(:destroy) # will remove the destroy button
  
action_item only: :show  do
  link_to I18n.t('active_admin.delete'), admin_resource_path(resource), method: :delete, data: { confirm: I18n.t('active_admin.delete_confirmation') }, class: "delete_link" if resource.deletable?
end

对不起我糟糕的格式。
