在 rails_admin 关联中更改类似查询

Question

我正在使用 rails admin 并且有两个简单的模型：

class Spot < ActiveRecord::Base
    has_many :user_spots
end

class UserSpot < ActiveRecord::Base
    belongs_to :spot
end

RailsAdmin.config do |config|
    config.model UserSpot do
        exclude_fields :id, :created_at, :updated_at
    end
end

当我在管理区域添加新 Spot 时，它会正确显示下拉列表，

但是当我开始输入时，它默认执行以下sql：

  Spot Load (0.6ms)  SELECT  `spots`.* FROM `spots` WHERE ((LOWER(spots.name) LIKE '%n%') OR (LOWER(spots.about) LIKE '%n%') OR (LOWER(spots.hours) LIKE '%n%') OR (LOWER(spots.location) LIKE '%n%') OR (LOWER(spots.call_info) LIKE '%n%') OR (LOWER(spots.website) LIKE '%n%') OR (LOWER(spots.menu) LIKE '%n%'))  ORDER BY spots.id desc LIMIT 30

我只想搜索姓名。有可能吗？

你可以这样配置：

RailsAdmin.config do |config|
  config.model UserSpot do
    exclude_fields :id, :created_at, :updated_at
    list do
      field :about do
        searchable false
      end

      field :hours do
        searchable false
      end

      # Like this mark false all the fields you don't want to 
      # search. By default all fields are searchable.
    end
  end
end
