CSV 未将格式正确的 JSON 导入数据库

Question

正如标题所说，这是我的代码：

require 'json'
def import_csv
  path = Rails.root.join('folder1', 'folder2', 'file.csv')
  counter = 0
  puts "inserts on table started..."
  CSV.foreach(path, headers: true) do |row|
    next if row.to_hash['deleted_at'] != nil
    counter += 1
    puts row.to_json #shows correct format
    someModel = someModel.new(row.to_hash) #imports incorrect format of json with backslash in db
    #someModel = someModel.new(row.to_json) #ArgumentError: When assigning attributes, you must pass a hash as an argument.
    someModel.skip_callbacks = true
    someModel.save!
    end
  puts "#{counter} inserts on table apps complete"
end
import_csv

我无法以正确的格式导入 CSV 文件。导入有效，但结构错误。

预期

{"data":{"someData":72}}

得到

"{\"data\":{\"someData\":72}}"

如何以正确的 JSON 格式导入它？

如果所有标题在模型的列名上都是正确的 也许你可以试试：

JSON.parse(row.to_json)
