sql - How to fix a multiple assignment issue? on Rails 4 -

Then, I have 3 tables accounts, users, and subscriptions that have deleted columns. Now when I delete an account, all models are requested once due to a multiple assignment error as shown below:

  for start 127.0.0.1 "/ admin / Accounts / 3 "Delayed -10-27 19:38:48 0200 by SaasAdmin :: AccountsController # HTML deleted as processed parameters: {" authenticity_token "= & gt; "Qo8NxYhezJUz2YylGxHlx2ou125UNoRuEcXbrnzyiN4 =", "id" = & gt; "3"} Select AppSetting Load (0.3ms) "App_settings".
