如何在config/initializer /rails_admin.rb的“可见的do”块中获得“current_user”?

I'm trying to implement something similar to this:

我正在尝试实现类似的东西:

RailsAdmin.config do |config|
  config.model Team do
    list do
      field :name
      field :created_at
      field :revenue do
        visible do
          current_user.roles.include?(:accounting) # metacode
        end
      end
    end
  end
end

I know in the README it says the example is theoretical, but I keep getting that current_user is not found within that block. I'm authorizing with CanCan:

在README中，我知道这个例子是理论上的，但是我一直得到，current_user没有在那个块中找到。我和康康舞授权:

RailsAdmin.authorize_with :cancan

RailsAdmin。authorize_with:康康舞

At the top of rails_admin.rb in config/initializers

在rails_admin顶部。rb配置/初始值设定项

Can anyone tell me how to get current_user available within the visible block? I'd like to only show certain fields in the "List" view if a user is an admin.

谁能告诉我如何使current_user在可见块中可用吗?如果用户是管理员，我只希望在“列表”视图中显示某些字段。

3 个解决方案

#1

Since current_user is included as a helper in the view, you can get it through the bindings hash:

因为current_user作为助手包含在视图中，所以可以通过绑定散列:

visible do
  bindings[:view].current_user.has_role? :admin # This works for Devise
end

I got the idea from this other question: How to set the user to current_user when creating a new model using rails_admin

我从另一个问题中得到了这个想法:如何在使用rails_admin创建新模型时将用户设置为current_user

Hope it helps.

希望它可以帮助。

#2

Initializers are run once on application startup, so I don't think you can get a current user from within an initializer like this.

初始化器在应用程序启动时只运行一次，所以我认为您无法从这样的初始化器中获得当前用户。

#3

I have not tried this myself, but you may find this useful:

我自己没有尝试过，但你会发现这很有用:

In short, define RailsAdmin::Config.current_user_method in the rails_admin initializer.

简而言之,定义RailsAdmin::配置。rails_admin初始化器中的current_user_method。
