Question

我在拥有数万条记录的模型中使用Searchlogic，并且不希望在第一次加载搜索页面时首先显示它们。如果没有：search params，如何从searchlogic获取空搜索对象？

  def search
    @products = []
    if params[:search] && !params[:search].blank?
      @search = Product.searchlogic(params[:search])
    else
      @search = Product.searchlogic(....What goes here to get an empty searchlogic object?...)
    end
    @products = @search.all
  end

将您的逻辑更改为：

def search
    @products = []
    @search = params[:search] && !params[:search].blank? ?
        Product.searchlogic(params[:search]) : nil
    @products = @search.all unless @search.nil?
end

当然，你可以保留你的if语句：

def search
    @products = []
    @search = nil
    if params[:search] && !params[:search].blank?
        Product.searchlogic(params[:search])
    end
    @products = @search.all unless @search.nil?
end

如何在没有记录的情况下初始化searchlogic
