Sql 选中多个复选框时将数组保存在数据库中

我有个大问题！！我想这真的需要数组，当我只检查了一个时，看看我的控制台：

{"value_solve"=>["", "", "333", ""], "contract_number"=>["33"]}
-----
  SQL (317.5ms)  UPDATE "authorizations" SET "value_solve" = '', "situation" = 2 WHERE "authorizations"."contract_number" = ?  [["contract_number", "33"]]

之后，当我只选中一个时，第一个：

{"value_solve"=>["111", "", "", ""], "contract_number"=>["11"]}
-----
  SQL (317.5ms)  UPDATE "authorizations" SET "value_solve" =  '111 ', "situation" = 2 WHERE "authorizations"."contract_number" = ?  [["contract_number", "11"]]

最后，当我不止一次：

{"contract_number"=>["11", "44"], "value_solve"=>["111", "", "", "444"]}
-----
  SQL (297.7ms)  UPDATE "authorizations" SET "value_solve" = '111', "situation" = 2 WHERE "authorizations"."contract_number" = ?  [["contract_number", "11"]]
  SQL (121.9ms)  UPDATE "authorizations" SET "value_solve" = '', "situation" = 2 WHERE "authorizations"."contract_number" = ?  [["contract_number", "44"]]

这是我的控制器：

@selected_ids = params[:authorization][:contract_number]
  @authorizations = Authorization.where("contract_number in (?)", @selected_ids)
  auth_params = params[:authorization]
  auth_params[:contract_number].zip(auth_params[:value_solve]).each do |contract_number, value_solve|
      Authorization.where(contract_number: contract_number).update_all(value_solve: value_solve, situation: 2)
  end

只需在DB上保存第一个值，如何保存多个值？谢谢

据我所知，您希望id为

44

的

合同号与
值\u solve==“444”
关联。如果这是正确的，您应该从
值\u solve
数组中删除空格：

auth_params[:contract_number].zip(auth_params[:value_solve].reject(&:blank?))...

现在，
44
正在使用
value\u solve
的第二个元素进行更新，这显然是一个空字符串

有关更多详细信息，请参阅。
您可以在此处检查rails中以数组形式发送参数：
