    @search = Admin.search(params[:q])
    if params[:page]
      @admins = @search.result(:distinct => true).page(params[:page][:number]).per(params[:page][:size])
    else
      @admins = @search.result(:distinct => true).page(1).per(10)

      format.json {render json: @admins}
    end

访问http://dashboard.localhost.com:3000/admins.json时，我收到了正确的链接，page[size] param为10.后续页面只有一个管理对象可供展示

"links": {
    "self": "http://dashboard.localhost.com:3000/admins.json?page%5Bnumber%5D=1&page%5Bsize%5D=10",
    "next": "http://dashboard.localhost.com:3000/admins.json?page%5Bnumber%5D=2&page%5Bsize%5D=10",
    "last": "http://dashboard.localhost.com:3000/admins.json?page%5Bnumber%5D=5&page%5Bsize%5D=10"
  }

但如果我在这里访问最后一个链接，http://dashboard.localhost.com:3000/admins.json?page%5Bnumber%5D=5&page%5Bsize%5D=10 随后的JSON包含以下错误链接，page[size] param为1.由于此页面只显示一个管理对象，因此生成的所有其他链接包含page[size]=1

"links": {
    "self": "http://dashboard.localhost.com:3000/admins.json?page%5Bnumber%5D=5&page%5Bsize%5D=10",
    "first": "http://dashboard.localhost.com:3000/admins.json?page%5Bnumber%5D=1&page%5Bsize%5D=10",
    "prev": "http://dashboard.localhost.com:3000/admins.json?page%5Bnumber%5D=4&page%5Bsize%5D=10"
  }

通过替换来解决这个问题 @admins = @search.result(:distinct => true).page(params[:page][:number]).per(params[:page][:size])的{{1}}

页面[大小]当用户登陆只有1个结果的页面时，从10更新到1
