I am working with rails 3.2 and ruby 2.1.2p95. Through my application, sending 1000+ of emails. I want to send few email from smtp and few emails from sendgrid. So I have configured like below in Notifier.rb file
after_filter :set_delivery_options, :except => [:method1]
def set_delivery_options
message.delivery_method.settings.merge!(
:address => "smtp.gmail.com",
:port => 587,
:domain => "xxxxxxxx",
:user_name => "xxxxxxxxxxxxx",
:password => "xxxxxxxxxxxxx",
:authentication => "plain",
:enable_starttls_auto => true
)
end
My method is like below:
def customer_mailing(customer)
mail(
:to => customer.user.email,
:subject => "Testing",
#:bcc => EMAIL_BCC,
:content_type => "text/html"
)
set_headers
end
Whenever I call the above method, the mail is sending twice or more in some times on production server.
This is a newbie question so please excuse me, I have been working with rails, but this is the first time i am trying to require gems from a heroku app that does not include rails - just a plain Ruby app.
ok I have a app.rb file looking like this:
require "sinatra"
require 'koala'
require 'action_mailer'
ActionMailer::Base.raise_delivery_errors = true
ActionMailer::Base.delivery_method = :smtp
ActionMailer::Base.smtp_settings = {
:address => "smtp.sendgrid.net",
:port => 587,
:domain => "MYDOMAIN",
:authentication => :plain,
:user_name => "USER_NAME",
:password => "PASSWORD",
:enable_starttls_auto => true
}
ActionMailer::Base.view_paths= File.dirname(__FILE__)
class TestMailer < ActionMailer::Base
default :from => "MY_EMAIL"
def welcome_email
mail(:to => "MY_EMAIL", :subject => "Test mail", :body => "Test mail body")
end
end
What I would like to do is run
TestMailer::deliver_test_email
in the console and get the details or run
TestMailer::deliver_test_email.deliver
to send a test email
but all i get is :
NameError: uninitialized constant Object::TestMailer
I have included actionmailer in the Gemfile and its also in the Gemfile.lock
I am sure it is something straight forward for an experienced Ruby dev, but I am struggling could anyone help me please?
Thanks
After a few hours of testing and research I ended up using Mail instead, this was my final code which when run works fine, I hope it helps anyone who is having the same issues as I was :)
require 'mail'
Mail.defaults do
delivery_method :smtp, { :address => "smtp.sendgrid.net",
:port => 587,
:domain => "MY_DOMAIN",
:user_name => "USER_NAME",
:password => "PASSWORD",
:authentication => 'plain',
:enable_starttls_auto => true }
end
mail = Mail.deliver do
to 'EMAIL'
from 'Your Name <NAME#MY_DOMAIN>'
subject 'This is the subject of your email'
text_part do
body 'hello world in text'
end
html_part do
content_type 'text/html; charset=UTF-8'
body '<b>hello world in HTML</b>'
end
end
I followed all the instructions on heroku and sendgrid but users receive an error when they try to sign up.
I ran the logs and here is the error.
What is wrong here?
2013-07-01 app[web.1]: Net::SMTPFatalError (550 Cannot receive from specified address <jay.mancho1#gmail.com>: Unauthenticated senders not allowed
my settings;
config/initializers/devise.rb
config.mailer_sender = "jay.mancho1#gmail.com"
config/environments/production.rb
config.action_mailer.default_url_options = { :host => '***.herokuapp.com' }
ActionMailer::Base.smtp_settings = {
:address => "smtp.sendgrid.net",
:port => "25",
:authentication => :plain,
:user_name => ENV['***#heroku.com'],
:password => ENV['***'],
:domain => ENV['heroku.com']
}
You need to change the line where you are setting the username and password to be ENV['SENDGRID_USERNAME'] and ENV['SENDGRID_PASSWORD'], not your actual password. These values are stored on the server and should not appear in your code.
I've got a simple Rails 3.2.7 app with Devise added that is deployed to Heroku with Sendgrid added. It works fine on heroku for everything except when it needs to do a password retrieve which requires sending an email. From all the posts i have read i suspect i am somehow setting up the mail parameters incorrectly. Any suggestions are appreciated.
For config/environments/production.rb i added
config.action_mailer.default_url_options = { :host => 'smtp.sendgrid.net'}
for config/initializers/devise.rb i added
config.mailer_sender = "mail-to-send#from.com"
and for config/environments.rb i added
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
}
So, your problem is you were referencing the wrong environment variables. Heroku stores your SendGrid credentials in ENV['SENDGRID_USERNAME'] and ENV['SENDGRID_PASSWORD']. You were using your actual username and password as the key names.
This will work:
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
}
i am using Pony.mail to send mail within Sinatra, what i have now is two forms, one that only sends an email address for subscription to newsletter and the second form is a contact form, both are going through the same action.
What I am trying to achieve is if the subscription field is completed then only send those params or if the contact form is completed and sent then send those params
Heres what i come up with so far, but getting undefined method nil
post '/' do
require 'pony'
Pony.mail(
:from => params[:name] || params[:subscribe],
:to => 'myemailaddress',
:subject => params[:name] + " has contacted you via the Website" || params[:subscribe] + " has subscribed to the newsletter",
:body => params[:email] + params[:comment],
:via => :smtp,
:via_options => {
:address => 'smtp.gmail.com',
:port => '587',
:enable_starttls_auto => true,
:user_name => 'myemailaddress',
:password => 'mypassword',
:authentication => :plain,
:domain => "localhost.localdomain"
})
redirect '/success'
end
is this even possible or would each form have to be dealt with individually?
Thanks
There are several stages I'd go through to refactor this code.
1. Extract the things that are changing (and make them more Rubyish)
post '/' do
require 'pony'
from = params[:name] || params[:subscribe]
subject = "#{params[:name]} has contacted you via the Website" ||
"#{params[:subscribe]} has subscribed to the newsletter"
body = "#{params[:email]}#{params[:comment]}"
Pony.mail(
:from => from,
:to => 'myemailaddress',
:subject => subject,
:body => body,
:via => :smtp,
:via_options => {
:address => 'smtp.gmail.com',
:port => '587',
:enable_starttls_auto => true,
:user_name => 'myemailaddress',
:password => 'mypassword',
:authentication => :plain,
:domain => "localhost.localdomain"
})
redirect '/success'
end
2. Make clear your intentions
in this case, that there are two branches through the code.
post '/' do
require 'pony'
if params[:name] # contact form
from = params[:name]
subject = "#{params[:name]} has contacted you via the Website"
else # subscription form
from = params[:subscribe]
subject = "#{params[:subscribe]} has subscribed to the newsletter"
end
body = "#{params[:email]}#{params[:comment]}"
Pony.mail(
:from => from,
:to => 'myemailaddress',
:subject => subject,
:body => body,
:via => :smtp,
:via_options => {
:address => 'smtp.gmail.com',
:port => '587',
:enable_starttls_auto => true,
:user_name => 'myemailaddress',
:password => 'mypassword',
:authentication => :plain,
:domain => "localhost.localdomain"
})
redirect '/success'
end
(I'm not a big fan of setting local vars within conditional branches, but we'll ignore that for clarity. I'd probably create a hash before the conditional with the keys already done, and then populate it in the branches but YMMV.)
3. Extract what doesn't change from what does.
Sinatra has a configure block just for this kind of thing.
require 'pony'
configure :development do
set :email_options, {
:via => :smtp,
:via_options => {
:address => 'smtp.gmail.com',
:port => '587',
:enable_starttls_auto => true,
:user_name => 'myemailaddress',
:password => 'mypassword',
:authentication => :plain,
:domain => "localhost.localdomain"
}
end
Pony.options = settings.email_options
Notice I've added :development as you may want to set it up differently for production.
Now your route is a lot cleaner and easier to debug:
post '/' do
if params[:name] # contact form
from = params[:name]
subject = "#{params[:name]} has contacted you via the Website"
else # subscription form
from = params[:subscribe]
subject = "#{params[:subscribe]} has subscribed to the newsletter"
end
body = "#{params[:email]}#{params[:comment]}"
Pony.mail
:from => from,
:to => 'myemailaddress',
:subject => subject,
:body => body,
redirect '/success'
end
My last tip, would be to put as many of those Pony options into ENV vars, which will not only keep things like passwords out of source control but also allow you to change the settings a lot easier. Perhaps put them in a Rakefile and load different environments for different contexts etc.
To use environment variables, I do the following:
# Rakefile
# in this method set up some env vars
def basic_environment
# I load them in from a YAML file that is *not* in source control
# but you could just specify them here
# e.g. ENV["EMAIL_A"] = "me#example.com"
end
namespace :app do
desc "Set up the environment locally"
task :environment do
warn "Entering :app:environment"
basic_environment()
end
desc "Run the app locally"
task :run_local => "app:environment" do
exec "bin/rackup config.ru -p 4630"
end
end
# from the command line, I'd run
`bin/rake app:run_local`
# in the Sinatra app file
configure :production do
# these are actual settings I use for a Heroku app using Sendgrid
set "email_options", {
:from => ENV["EMAIL_FROM"],
:via => :smtp,
:via_options => {
:address => 'smtp.sendgrid.net',
:port => '587',
:domain => 'heroku.com',
:user_name => ENV['SENDGRID_USERNAME'],
:password => ENV['SENDGRID_PASSWORD'],
:authentication => :plain,
:enable_starttls_auto => true
},
}
end
# then a block with slightly different settings for development
configure :development do
# local settings…
set "email_options", {
:via => :smtp,
:via_options => {
:address => 'smtp.gmail.com',
:port => '587',
:enable_starttls_auto => true,
:user_name => ENV["EMAIL_A"],
:password => ENV["EMAIL_P"],
:authentication => :plain,
:domain => "localhost.localdomain"
}
}
end
I usually keep most of these setting in a YAML file locally for development, but add these to the production server directly. There are lots of ways to handle this, YMMV.
