Kaminari：未定义的方法 total_pages

Question

我在 Kaminari 上遇到问题 Rails 4.

这是我的renters_controller.rb

def search
  @location = params[:search]
  @distance = params[:km]
  @renters = Renter.near(@location, 30000).order("distance")
  @renters = @renters.page(params[:page])

  if @renters.empty?
    @renters = Renter.all
    search_map(@renters)
  else
    search_map(@renters)
  end
end

和我的观点 search.html.haml。

.row
  = paginate @renters

和我的错误信息

在控制器中，如果我写

就可以了

@renters = Renter.page(params[:page])

有什么想法吗？

Answer 1

试试这个，我希望它能奏效。

def search
  @location = params[:search]
  @distance = params[:km]
  @renters = Renter.near(@location, 30000).order("distance")

  if @renters.empty?
    @renters = Renter.all
    search_map(@renters)
  else
    search_map(@renters)
  end
  @renters = @renters.page(params[:page])
end
