`remove_column` triggers check even when wrapped in `safety_assured`

[brevio-nicolay]

Hello,

First of all, thank you very much for the excellent library.

Gem version: 0.19.1
Rails version: 7.0.4

class User < ApplicationRecord
  self.ignored_columns += ['name', 'email_address']
end

class RemoveOldColumns < ActiveRecord::Migration[7.0]
  def change
    safety_assured { remove_columns :users, :name, :email_address }
  end
end

Triggers:

rails aborted!
StandardError: An error has occurred, this and all later migrations canceled:

=== Dangerous operation detected #strong_migrations ===

Active Record caches database columns at runtime, so if you drop a column, it can cause exceptions until your app reboots.
A safer approach is to:

1. Ignore the column:

  class User < ApplicationRecord
     self.ignored_columns += ["name", "email_address"]
  end

2. Deploy
3. Wrap column removing in a safety_assured { ... } block

  class RemoveUnusedColumns < ActiveRecord::Migration[7.0]
    def change
      safety_assured { remove_columns :users, :name, :email_address }
    end
  end

4. Remove column ignoring from step 1
5. Deploy

I have already completed steps (1-3), but when I try to run the migration, this errors keeps stopping me.

Not the right gem I think 😅

Do you use both gems?

@fatkodima oh my, you're quite right. Somehow they both got added to the Gemfile! Sorry for the trouble, and thanks again for the excellent work 👍
