[Bcrypt] how to cancel presence: true of has_secure_password

I'm using bcrpt, but I want to set a password arbitrarily

I made it possible to set a password for posts with bcrpt, By default, empty posts are set to be played, so I will show you how to cancel it.

Disable validation

Just add (validations: false) next to has_secure_password.

qiita.rb


class Post < ApplicationRecord
  has_secure_password(validations: false)
end

Summary

You can now post blank posts by disabling validation.
