在ActiveAdmin过滤器中使用ActiveRecord范围

Question

在我的rails项目中我有模型:

class Panel < ActiveRecord::Base
  has_many :surveys

  scope :by_survey_name, ->(survey_name) {
    joins(:surveys).where('surveys.survey_name LIKE (?)', "%#{survey_name}%")
  }
end

问题是如何在activeadmin fiter中使用此范围？

Answer 1

添加到型号:

  def self.ransackable_scopes(_auth_object = nil)
    [:by_survey_name]
  end

然后在资源中:

  filter :by_survey_name, as: :string
