# Email ## Stack * Email sending leverages Rails' [action mailer](http://guides.rubyonrails.org/action_mailer_basics.html) * Action mailer is integrated with [active job](http://edgeguides.rubyonrails.org/active_job_basics.html), which is a generic API for queueing jobs * ActiveJob requires you to specify a backend. there are a few built in by default. We use one of them, called "delayed job" * in `cobudget-api/config/application.rb:` `config.active_job.queue_adapter = :delayed_job` * delayed\_job is an external Gem, listed as a dependency in the Gemfile. ## Development When developing with emails locally, make sure mailcatcher is running. assuming mailcatcher is installed (`gem install mailcatcher`), in a terminal window just run `mailcatcher`, then visit `http://localhost:1080/` to see your mails coming through. Note, for messages to get queued for actual sending, you need to append a [delivery call](http://edgeapi.rubyonrails.org/classes/ActionMailer/MessageDelivery.html) (`deliver_now`, `deliver_later`) otherwise you are just creating a MailMessage object, and it will seem to be failng silently because you're actually not asking for it to be delivered. this is working for `deliver_now` emails. i am still not sure how deliver\_later is working, or whether it's working. i don't see them coming through mailcatcher, and am not sure if it's because the delayed\_job queue is not running or something else. run `bundle exec rake jobs:work` to start a background process for delayed jobs. additional info about delayed\_job at ## Production ## Sending Production mails are being sent through sendgrid. we do not have a login for the existing account yet. ## Log reporting emails `config/initializers/delayed_job_airbrake.rb` seems to be configured to work with [airbrake](https://airbrake.io/) on production, but there are no airbrake settings configured on heroku.
