When
ActionMailer
is not defined we have emptyapp/mailers/devise/mailer.rb
file and Zeitwerk doesn't like that and errors withexpected file app/mailers/devise/mailer.rb to define constant Devise::Mailer
The fix is to tell Zeitwerk to ignore that file if
ActionMailer
constant if not defined.I tried to write a spec for it but since specs are run in the same process it's hard to have two Rails applications where one of them has
ActionMailer
define and the seconds one doesn't.closes #5140, #5485
