Question

控制器

format.csv { send_data @find_customer.to_csv, :filename => "customer" + ".csv" }
format.xls { send_data @find_customer.to_csv(col_sep: "\t"), filename: 'customer.xls'}

模型

  def self.to_csv(options = {})
    CSV.generate(options) do |csv|
      csv << ["SHW#", "LeadId", "Fullname", "Address", "City", "State", "Zip", "Phone", "Email", "Created-At"]
      all.each do |customer|
        csv << [customer.id, customer.leadid, "#{customer.first_name} #{customer.last_name}", customer.customer_address, customer.customer_city, customer.customer_state, customer.customer_zip, customer.customer_phone, customer.email, customer.created_at.strftime("%m/%d/%Y")] 
      end
    end
  end

如何在to_csv方法中传递额外参数。我想在to_csv方法中传递start_date和end_date所以我该怎么办？

如果我通过

format.xls {send_data @ find_customer.to_csv（col_sep：＆＃34; \ t＆＃34;，：start_date =＆gt;＆＃34; date＆＃34;），filename：＆＃39; customer.xls＆＃ 39;}

然后得到如下错误：未知选项start_date

试试这个：

format.csv { send_data @find_customer.to_csv({}, '2014-05-08', '2014-05-10'), :filename => "customer" + ".csv" }

模型

def self.to_csv(options = {}, start_date = '', end_date = '')
  CSV.generate(options) do |csv|
    csv << ["SHW#", "LeadId", "Fullname", "Address", "City", "State", "Zip", "Phone", "Email", "Created-At", "Start", "End"]
    all.each do |customer|
      csv << [customer.id, customer.leadid, "#{customer.first_name} #{customer.last_name}", customer.customer_address, customer.customer_city, customer.customer_state, customer.customer_zip, customer.customer_phone, customer.email, customer.created_at.strftime("%m/%d/%Y"), start_date, end_date] 
    end
  end
end
