Rails 3 :: Not abandon sending mail within ActionMailer action
In ActionMailer (Rails 3) you can’t decide not to send an email. For instance, you have the following mailer:
class FooMailer < ActionMailer::Base
def bar_email
if some_condition
mail(...)
else
# Can I do nothing? No :-(
end
end
end
If you invoke FooMailer.bar_email.deliver!, when same_condition is false you will get the following error:
ArgumentError: A sender (Return-Path, Sender or From) required to send a message
The workaround for that is move the condition to the place where you are making the call to FooMailer.bar_email.deliver!
