Question

我正在使用CSV类将结果导出到csv。我现在正在使用它，但它只将我的搜索查询导出为CSV，而不是结果（显示在我的'show;页面上）。

search.rb

class Search < ActiveRecord::Base

 def to_xls(options = {})
  {
      "Id" => id.to_s,
      "firstname" => firstname,
      "surname" => surname,
      "officenumber" => officenumber,
      "department" => department,
      "division" => division,
      "address" => address,
      "notes" => notes
  }
 end
end

searches_controller.rb

def show
    @search = Search.find(params[:id])

    respond_to do |format|
        format.html
        format.xls { send_data @searches.to_xls, content_type: 'application/vnd.ms-excel', filename: 'search.xls' }
    end
end

mime_types.rb

Mime::Type.register "application/vnd.ms-excel", :xls

你应该试试这个，

def self.to_xls(options = {})
  CSV.generate(options) do |csv|
    csv << column_names
    all.each do |product|
      csv << product.attributes.values_at(*column_names)
    end
  end
end

链接应该像<%= link_to "Excel", your_path(format: "xls") %>

您可以找到完整的流程here来实现它。
