Rails app Foreign key error: Administrative user not allowed to delete other users in

sql ruby-on-rails ruby heroku

To add an alternative for those who don't want to delete associated records (maybe you want to keep the cars records for later use).

class User < ActiveRecord::Base  ....  has_many :cars, dependent: :nullifyend

The associated record foreign_key will be set to nil.

Can be useful for people like me landing on your question!

sql ruby-on-rails ruby heroku

Add cascading delete to yout User model:

class User < ActiveRecord::Base  ....  has_many :cars, :dependent => :delete_allend

sql ruby-on-rails ruby heroku

creating a migration with

add_foreign_key :identities, :users, on_delete: :cascade
