问题
Following a tutorial where I am adding user authentication to a basic rails app.
There is a step where I have to add the following code to a setup_mail.rb file
if Rails.env.development?
ActionMailer::Base.delivery_method = :smtp
ActionMailer::Base.smtp_settings = {
address: 'smtp.sendgrid.net',
port: '587',
authentication: :plain,
user_name: ENV['SENDGRID_USERNAME'],
password: ENV['SENDGRID_PASSWORD'],
domain: 'heroku.com',
enable_starttls_auto: true
}
end
I have added the sendgrid addon, and put user id and password on the application.yml file as well.
But when I sign up, I do not receive a confirmation mail.
cross checked the development.rb file as well and made sure the following code was present
....
config.action_mailer.default_url_options = { host: 'localhost:3000' }
config.action_mailer.delivery_method = :smtp
config.action_mailer.perform_deliveries = true
end
Followed the tutorial word to word. Hence really stumped! Google pointed me to a few places and confused me futher!
This is how my migration db file looks like at the moment
class DeviseCreateUsers < ActiveRecord::Migration
def change
create_table(:users) do |t|
## Customization
t.string :name
## Database authenticatable
t.string :email, null: false, default: ""
t.string :encrypted_password, null: false, default: ""
## Recoverable
t.string :reset_password_token
t.datetime :reset_password_sent_at
## Rememberable
t.datetime :remember_created_at
## Trackable
t.integer :sign_in_count, default: 0, null: false
t.datetime :current_sign_in_at
t.datetime :last_sign_in_at
t.string :current_sign_in_ip
t.string :last_sign_in_ip
## Confirmable
t.string :confirmation_token
t.datetime :confirmed_at
t.datetime :confirmation_sent_at
t.string :unconfirmed_email # Only if using reconfirmable
## Lockable
# t.integer :failed_attempts, default: 0, null: false # Only if lock strategy is :failed_attempts
# t.string :unlock_token # Only if unlock strategy is :email or :both
# t.datetime :locked_at
t.timestamps
end
add_index :users, :email, unique: true
add_index :users, :reset_password_token, unique: true
# add_index :users, :confirmation_token, unique: true
# add_index :users, :unlock_token, unique: true
end
end
Here is my user.rb file as well
class User < ActiveRecord::Base
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable, :confirmable
end
These are the steps I followed in order
- Installed devise gem, ran
bundle rails g devise:install- Added the above code to development.rb file
rails g devise:viewsrails g devise User- Uncommented
confirmablein the migration file` rake db:migrate- Added
:confirmableto the User class in user.rb heroku addons:add sendgrid:starterheroku congif:get SENDGRID_USERNAMEheroku config:get SENDGRID_PASSWORD- Created config/initializers/setup_mail.rb and added the above mail settings.
- Installed figaro.
- Added environment variables to application.yml file
- `figaro heroku:set -e production
Update
Added mail settings in development.rb as well, no luck.
Tried changing the domain from domain: 'heroku.com' to domain: 'sendgrid.com', no luck.
Here is the server log. It appears that the mail has been sent but I cannot find it in the inbox or spam

Check to make sure Sendgrid doesn't have your account on hold. Log in through your Heroku dashboard. Then click on your app. Then under addons, click on Sendgrid. This will take you to their dashboard. If there is a warning saying that your account is on hold pending review, you'll have to contact them and have them remove it.

You are running it for development mode. Mails are formed and can be seen in logs but not delivered. They will not be sent in dev mode by default.To enable, use this in development.rb
config.action_mailer.perform_deliveries = true
use the below code in config/environments/development.rb
config.action_mailer.smtp_settings = {
:address => "smtp.sendgrid.net",
:port => 587,
:domain => "sendgrid.com",
:user_name => ""
:password => ""
:authentication => 'plain',
:enable_starttls_auto => true }
}

In mail_setup.rb, try changing the first line to:
if Rails.env.development? || Rails.env.production?

I ran into the same problem with :confirmable. I was not able to get the email to send, but I was able to trick the app into thinking that it had been sent and confirmed - and therefore login.
:confirmable info
In the console:
User.find(1).confirm # returns true unless it's already confirmed
User.find(1).confirmed? # true/false
User.find(1).send_confirmation_instructions # manually send instructions
