ruby on rails 很好的跟mongodb进行了结合,gem包:
地址:https://rubygems.org/gems/mongoid
文档:https://docs.mongodb.com/ecosystem/tutorial/ruby-mongoid-tutorial/#ruby-mongoid-tutorial
最新还用的查询
Model.where(name:/abc/)
这个可以查找model表中name字段有abc的所有内容。
分页,可以结合willpage
def self.paginate(options = {}) options[:page] = options[:page].to_i options[:page] = 1 if options[:page] == 0 options = base_options options ::WillPaginate::Collection.create(options[:page], options[:per_page]) do |pager| items_count = options[:total_entries] || self.count fill_pager_with self.skip(options[:offset]).limit(options[:per_page]), items_count, pager end end def self.base_options(options) options[:page] ||= 1 options[:per_page] ||= 20 options[:offset] = (options[:page].to_i - 1) * options[:per_page].to_i options end def self.fill_pager_with(medias, size, pager) pager.replace medias.to_a pager.total_entries = size end
