Sendgrid for an email feature within Ruby on Rails app - ruby-on-rails

Question

I would like to use Sendgrid to manage outgoing emails from a 3.2.2 version rails app I am developing with the help of a friend. She has email working from within the app using gmail, on her local/dev build. I need sendgrid up and running.
I cannot even get it to work locally.
From my development.rb file
config.action_mailer.default_url_options = { :host => 'localhost:3030' }
config.action_mailer.smtp_settings = {
:user_name => ENV['EMAIL_USERNAME'],
:password => ENV['EMAIL_PASSWORD'],
:domain => 'myapplicationdomain.com',
:address => 'smtp.sendgrid.net',
:port => 587,
:authentication => 'plain',
:enable_starttls_auto => true
}
config.action_mailer.delivery_method = :smtp
Then I have a variable file in the root of my application that includes the following:
export EMAIL_USERNAME=sendgridusername
export EMAIL_PASSWORD=sendgridpassword
export MAIL_TO=report#myapplicationdomain.com
Here is the code from my mailer
class StatusMailer < ActionMailer::Base
default from: "reports#myapplicationdomain.com"
def status_report(report)
#greeting = "Hello"
#report = report
if ENV['MAIL_TO']
email = ENV['MAIL_TO'] if ENV['MAIL_TO']
else
email = #report.user.email
end
#statuses = #report.statuses
#reviewers = #report.user.reviewers
bcc = []
#reviewers.each do |reviewer|
bcc.append(reviewer.email)
end
#bcc = bcc
mail(to: email, bcc: bcc, subject: 'Status Report')
end
end
Am I missing some other setting? What about the MAIL_TO field in the variable, I am not certain what that should be set to, or if it even needs to be declared.
Is there another file that I should be editing? I had this working several days ago, but functionality somehow slipped away :0
Rails server says that emails were sent, but sendgrid has no record; nor are the emails being received by addresses on the distribution list.
Thank you in advance for any assistance.

Answer 1

Do you have the following settings in your config/environments/development.rb?
config.action_mailer.raise_delivery_errors = true
config.action_mailer.perform_deliveries = true
If not, add them to your config file and restart your server.
Update:
This error suggests that you're not authenticated. Are you sure the values of your ENV['EMAIL_USERNAME'] and ENV['EMAIL_PASSWORD'] variables are present/correct?

This post:
Sendgrid / email sending issues in Ruby on Rails (hosted on Heroku)
Got me up and running. The key being putting the SMTP and sendgrid information in the environment.rb file.
I can't explain exactly why that made the difference, but it did.
