How to send email in rails - ruby-on-rails

Question

The following is my controller file:
class BiodataController < ApplicationController
def store
#user=params[:username]
#age=params[:age]
#gender=params[:gender]
#mstatus=params[:mstatus]
#language=params[:language]
#email=params[:email]
#mobile=params[:mobile]
if params[:username].present? && params[:age].present? && params[:gender].present? && params[:mstatus].present? && params[:language].present? && params[:email].present? && params[:mobile].present?
Biodatum.create(name: #user, age: #age, gender: #gender, mstatus: #mstatus, language: #language, email: #email, mobile: #mobile)
Infomail.sendmail(#email)
render 'store'
else
render 'Error'
end
end
end
My requirement is to send email to the address stored in #email. So I created the mailer as 'Infomail'. The following is my mailer file.
class Infomail < ApplicationMailer
default from: 'abc#xyz.co.in'
def sendmail(user)
#user = user
mail(to: #user.email, subject: 'sample mail')
end
end
And I also have html file under 'app/views/infomail/sendmail.html.erb'. But it doesn't work. Can any one explain me what is the bug in
my code.

Answer 1

I'll recommend that you take a look at http://guides.rubyonrails.org/action_mailer_basics.html for starters.
For sending mails, you'll have to use the deliver_now (Immediate) or deliver_later (Queue for worker) methods, like so:
InfoMailer.sendmail(#user).deliver_now
Note that I renamed it to InfoMailer, because that's the standard naming, of mailers.

Answer 2

If you want to test you mailer into development environment just open your development.rb file and write below code inside for smtp configuration.
config.action_mailer.default_url_options = { host: 'url of your application' }
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
address: 'address of your mailer',
port: 465,
domain: ENV['YOUR_DOMAIN_NAME'],
user_name: ENV['YOUR_USER_NAME'],
password: ENV['YOUR_PASSWORD'],
authentication: :plain,
ssl: true,
tls: true,
enable_starttls_auto: true
}
please change above configuration as per your mailer smtp settings.
Now create tamp let of your mail as per you requirements. file path as per below:
app -> view -> common_mailer inside of this please make sendmail.html.erb file.

Answer 3

You are sending #email which is a String in params while you are expecting Object on which you can call .email
#bio = Biodatum.create(name: #user, age: #age, gender: #gender, mstatus: #mstatus, language: #language, email: #email, mobile: #mobile)
Infomail.sendmail(#bio)
This will pass Biodatum instance on which you can call .email
Also to avoid confusion you can change your mailer method
def sendmail(bio)
#bio = bio
mail(to: #bio.email, subject: 'sample mail')
end
If you are making these changes, you will also need to change them in sendmail.html
EDIT
Make sure you have configured the settings in /config/environments/development.rb and /config/environments/production.rb
config.action_mailer.delivery_method = :smtp
# SMTP settings for gmail
config.action_mailer.smtp_settings = {
:address => "smtp.gmail.com",
:port => 587,
:user_name => ENV['gmail_username'],
:password => ENV['gmail_password'],
:authentication => "plain",
:enable_starttls_auto => true
}
