如何在ruby on rails oop中复合csv文件数据

require 'csv'

class CsvData
  def self.read(file_path)
    data = []
    CSV.foreach(file_path, headers: true) do |row|
      data << row.to_h
    end
    data
  end

  def self.write(file_path, data)
    CSV.open(file_path, 'w', write_headers: true, headers: data.first.keys) do |csv|
      data.each do |row|
        csv << row.values
      end
    end
  end

  def self.process(file_path)
    data = read(file_path)
    # 在这里进行数据处理操作，例如筛选、排序、转换等
    processed_data = data.select { |row| row['category'] == 'example' }
    write(file_path, processed_data)
  end
end

class DataController < ApplicationController
  def process_csv
    file_path = 'path/to/your/csv/file.csv'
    CsvData.process(file_path)
    redirect_to root_path, notice: 'CSV file processed successfully.'
  end
end
