活性污染物的母物归属
原标题:Filter on parent object attribute in ActiveAdmin

我能够根据母子的特性过滤物体:

class Call < ActiveRecord::Base
  belongs_to :user
end

class User < ActiveRecord::Base
  has_many :calls
end

我能够这样做:

ActiveAdmin.register Call do
  filter :user
end

用户名,而不是提供所有用户的选择。 能否做到这一点?

问题回答

丹尼斯的解决方案几乎对我有利。 我只需要增加过滤器。 例如:

ActiveAdmin.register Call do
  filter :user_name, :as => :string
end

为此:

ActiveAdmin.register Call do
  filter :user_name
end

Since ActiveAdmin uses meta_search for filters their doc is very helpful: https://github.com/ernie/meta_search

在下一期发行的活性污染物(与1.0.0.pre合作)中,可使用Ransack方法。 因此,我要说的是一条属于用户的条款。

页: 1

ActiveAdmin.register Article do

  controller do
    def scoped_collection
      Article.includes(:user)
    end
  end  

  index do      
   column :id
   column :created_at
   column :title
   column("Author", sortable:  users.first_name ) { |item| link_to item.user.full_name, user_path(item.user) }
   actions
  end

  filter :user_first_name_cont, :as => :string
  filter :user_last_name_cont, :as => :string  

end

这里,用户——名称_cont_是洗衣方法,首先对相关用户进行过滤——姓名和连续手段包含。

您可以使用由主动提名人使用的专用资源,因此,你的名单自动由父母过滤。

ActiveAdmin.register User do
  # this is the parent resource
end

ActiveAdmin.register Call do
  belongs_to :user # nested below resource user
end

之后,你可以使用 r车路线,看看活性污染物产生的新通道: 希望会有助于

d 我说,这在很大程度上取决于你在模式之间有什么样的协会——我需要几个小时来说明这一点。

class User < ActiveRecord::Base
  belongs_to :user
end

class Email < ActiveRecord::Base
  has_one :email
end

为了根据电子邮件对用户进行过滤,你这样做(登机忘记as:string<>code>。 部分内容是使你能够使用Lansack搜身方法,如 contains具等。

ActiveAdmin.register User do
  filter :user_email, :as => :string
end
