Devise and ActsAsTaggableOn - prevent loading tags with user

devise_tags_fix.rb

# frozen_string_literal: true

#
# Devise & ActsAsTaggableOn gems combination
# This fix redefine inspect method by excluding tag_lists form it.
#
# Because the way Devise redefines inspect method tag_lists are getting
# loaded on every user query.
#
# From Devise:
#
#   Redefine serializable_hash in models for more secure defaults.
#   By default, it removes from the serializable model all attributes that
#   are *not* accessible. You can remove this default by using :force_except
#   and passing a new list of attributes you want to exempt. All attributes
#   given to :except will simply add names to exempt to Devise internal list.
#
#   Redefine inspect using serializable_hash, to ensure we don't accidentally
#   leak passwords into exceptions.
#
