# This is a monkey patch which must be removed when migrating to Rails 5.1 from 5.0.
#
# In Rails 5.0 there was introduced a bug which casts types in the uniqueness validator.
# https://github.com/rails/rails/pull/23523/commits/811a4fa8eb6ceea841e61e8ac05747ffb69595ae
#
# That causes to bugs like this:
#
# 1) API::Users POST /user/:id/gpg_keys/:key_id/revoke when authenticated revokes existing key
# Failure/Error: let(:gpg_key) { create(:gpg_key, user: user) }
#
# TypeError:
# can't cast Hash
# # ./spec/requests/api/users_spec.rb:7:in `block (2 levels) in <top (required)>'
# # ./spec/requests/api/users_spec.rb:908:in `block (4 levels) in <top (required)>'
