Invalid delivery method

[fadynaffa3]

I am getting this error after commenting out config.action_mailer.mailgun_settings as it was raising undefined method mailgun_settings=' for ActionMailer::Base:Class`

Configuration:

• Rails 4.2.8
• Ruby 2.4.1
• mailgun-ruby 1.1.6

• Error Message is Invalid delivery method mailgin

@fadynaffa3 Could you try with Rails >= 5.0.0.1? I've got a sample application using Railgun that may help you set things up.

[fadynaffa3]

@pirogoeth already tried with rails 5 before and worked correctly but the issue is on rails 4.2.8 and the documentation didn't mention the supported rails version and it's confusing.
I can't update my project to rails 5 in one day to test mailgun usage with action_mailer

[pirogoeth]

@fadynaffa3 I will see what I need to do to make it work with Rails 4.2.8.

Thanks :)

Any luck with this?

[fadynaffa3]

@ivko999 try this:
ActionMailer::Base.add_delivery_method(:mailgun, Mailgun, default_options={})

This is Rails bug, same underlying cause as #104. Fixed by pending Rails PR rails/rails#35419

[Benjamin-Dobell]

Should probably note there is an issue with this Gem as well, as it's causing ActionMailer::Base to autoload earlier than it ought to. Fixed in PR #162.

Version 1.2.4 with the fix was published to rubygems. Closing.
