问题描述
Active Admin允许我定义索引页面上显示的过滤器像这样:
Active Admin allows me to define filters that are displayed on the index page like so:
ActiveAdmin.register Promo do filter :name filter :address filter :city filter :state filter :zip end我想将上面的所有字段合并为一个,以便我可以搜索包含名称或完整地址中搜索字符串的Promos。我的模型已经具有我可以使用的命名范围:
I would like to combine all the fields above into one, so that I can search for Promos that contain the search string in name or full address. My model already has a named scope that I can use:
class Promo < ActiveRecord::Base scope :by_name_or_full_address, lambda { |q| where('name LIKE :q OR address LIKE :q OR city LIKE :q OR state LIKE :q OR zip LIKE :q', :q => "%#{q}%") } end推荐答案
Active Admin使用 meta_search 过滤器。 ORed条件语法允许在一个查询中组合多个字段,例如
Active Admin uses the meta_search gem for its filters. ORed conditions syntax allows to combine several fields in one query, for example
Promo.metasearch(:name_or_address_contains => 'brooklyn')在Active Admin DSL中,这表示为
In Active Admin DSL this translates to
ActiveAdmin.register Promo do filter :name_or_address, :as => :string end更多推荐
