My Environment

Software	Version
Operating System	macOS Catalina 10.15.7
Jets	2.3.18
Ruby	2.5.8

Expected Behaviour

Attempting to send an email containing a link_to element inside the htlm.erb file successfully sends via console or job.

Current Behavior

ActionView::Template::Error (undefined method 'host' for nil:NilClass) is raised.
Error is originating from lib/jets/overrides/rails/common_methods.rb:5:in 'add_stage_name'.
https://github.com/boltops-tools/jets/blob/master/lib/jets/overrides/rails/common_methods.rb#L5

Step-by-step reproduction instructions

Run the following commands

jets new mail_test --database=postgresql --mode job
jets generate mailer TestMailer test_mail

Uncomment the following line in development.rb

config.action_mailer.raise_delivery_errors = false

Ensure the generated mail can be delivered

jets c
TestMailer::test_mail.deliver_now

Inside test_mail.html.erb add a link_to element

<%= link_to(
  "I am a link",
  "https://www.google.com/",
  style: "text-decoration: none;", target: :blank
) %>

Enter the jets console and attempt to send again

jets c

Note:

The same error occurs if the mailer is invoked from a job once deployed to AWS Lambda.

Code Sample

See the reproduction instructions. Only one comment is uncommented and a single block of code added to a generated html.erb

The relevant code that is erroring:
https://github.com/boltops-tools/jets/blob/master/lib/jets/overrides/rails/common_methods.rb#L5

Solution Suggestion

I am not so familiar with Jets, but am assuming this is happening due to the fact that the mail is being sent not via a request from a controller, but via the console or a job.

Commenting out the following line enables me to send emails from the console/job.

Jets::Controller::Stage.add(request.host, url)

@tongueroo
For the time being, I am needing to fork the repository and introduce the following changes.

jets/overrides/rails/common_methods.rb

def add_stage_name(url)
  request ? Jets::Controller::Stage.add(request.host, url) : url
end

I have no idea if this is the "correct" way to go about fixing the issue, but it is working as intended for me.

This is possible in Jets 5

https://blog.boltops.com/2023/12/05/jets-5-improvements-galore/

It was tested as part of testing Kingsman
