ruby-on-rails - 使用 will_paginate/searchlogic 搜索多个字段

Question

您如何在模型的多个字段中进行有效搜索？

# user.rb model
def self.search(search, page)  
  paginate :per_page => 20, :page => page,
  :conditions => 
    ['name like ? OR notes like ? OR code like ? OR city like ? OR state like ?,
    "%#{search}%","%#{search}%","%#{search}%","%#{search}%","%#{search}%"
    ], :order => 'name'

这段代码对于多个字段来说是可怕的，并且如果单词 #1 来自 :name 而单词 #2 来自 :code，则它不会返回结果。有没有更优雅的方式？

我认为这行得通

def self.search(search, page)
  fields = [:name, :notes, :code, :city, :state] 
  paginate :per_page => 20, :page => page,
  :conditions => [fields.map{|f| "#{f} like ?"}.join(' OR '),
    *fields.map{|f| "%#{search}%"}], :order => 'name'
