我想调出一个数据集。
ruby代码是:

get '/candy' do
    @pagedata = { :cur_page => 1, :post_count => 0, :per_page => 3 }
    # set the current page to show
    @pagedata[:cur_page] = params[:page].to_i unless params[:page].nil?
    @cands = DB[:candidates]
    #@cands = Post.by_created_at
    # set post_count
    @pagedata[:post_count] = DB[:candidates].count(:id)
    @cands = @cands.paginate(:page => @pagedata[:cur_page], :per_page => @pagedata[:per_page]) unless @cands.empty?
        erb :candy
    end

怎么了?感谢所有的帮助!
台词:
@cands = @cands.paginate(:page => @pagedata[:cur_page], :per_page => @pagedata[:per_page]) unless @cands.empty?

产生错误:
undefined method `paginate' for Sequel::Postgres::Dataset: "SELECT * FROM "candidates"

最佳答案

创建DB.extension(:pagination)对象后,需要添加DB

关于ruby - ruby sinatra,Postgres分页结果,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/18637966/
