选中多个复选框时将数组保存在数据库中

Question

I have a problem greatest!! I guess that really want Array, look my console when I checked just one:

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

After, when I checked just one, the first:

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

And, for last, when I just more then one:

{"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"]]

And this is my controller:

@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

Just save the first value on DB, how I can save more then one value? Thanks!

Answer 1

As I understood, you want the contract_number with id 44 to be “associated” with value_solve == "444" . If this is correct, you should remove blanks from your value_solve array:

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

Now 44 is being updated with the second element of value_solve , which is apparently an empty string.

See Array#zip for more details.
