選中多個復選框時將數組保存在數據庫中

Question

我有一個最大的問題！！ 我想那真的很想要 Array，當我只檢查一個時，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，當我只檢查一個時，第一個：

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

而且，最后，當我不止一個時：

{"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"]]

這是我的控制器：

@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

只需將第一個值保存在 DB 上，如何保存多個值？ 謝謝！

Answer 1

據我了解，您希望將 id 為44的contract_number與value_solve == "444" “關聯value_solve == "444" 。 如果這是正確的，您應該從value_solve數組中刪除空白：

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

現在44正在使用value_solve的第二個元素進行value_solve ，這顯然是一個空字符串。
