How to receive an email from users in rails? - ruby-on-rails

Question

I have a form that allows users to enter their names, email add, subject and message. When the user hits SEND, the message should be sent to me(admin).
I have this code under my development config...
config.action_mailer.delivery_method = :smtp
# SMTP settings for gmail
config.action_mailer.smtp_settings = {
:address => #user.email,
:port => 587,
:user_name => ENV['sys.questdentalusa#gmail.com'],
:password => ENV['passwordhere'],
:authentication => 'plain',
:enable_starttls_auto => true
}
and this code under my user_mailer
def welcome_email(user)
#user = user
mg_client = Mailgun::Client.new ENV['api_key']
message_params = {:from => ENV[#user.email],
:to => 'sys.questdentalusa#gmail.com',
:subject => #user.subject,
:text => #user.text}
mg_client.send_message ENV['domain'], message_params
end
It won't send the message. It's as if it did not execute.
The rule is, no model should be involved.
Example, you have an existing gmail account and wrote a message sent to me. I should receive your message from your entered gmail account.

Answer 1

Two things your developer config and message_params looks wrong,
in message_params : :from => ENV[#user.email] is should be like #user.email
in smtp_settings : :address => #user.email, is like "smtp.mailgun.org". checkout more smtp_settings at here

I got the answer for quite a while now and I just decided to might as well share it here. This is what I did in my development.rb
config.action_mailer.smtp_settings = {
address: "smtp.gmail.com",
port: 587,
domain: "gmail.com",
user_name: "sys.questdentalusa#gmail.com",
password: "passwordhere",
authentication: :plain,
enable_starttls_auto: true
}
This is what I got under my Mailer
class MessageMailer < ActionMailer::Base
default from: "sys.questdentalusa#gmail.com"
default to: "questdentalusa#gmail.com"
def new_message(contact)
#contact = contact
mail subject: 'Inquiry from website: ' + #contact[:subject]
end
end
I got this under new_message.text.erb
Name: <%= #contact[:name] %>
Email: <%= #contact[:email] %>
Message: <%= #contact[:content] %>
And this is under my controller
class HomeController < ApplicationController
skip_before_filter :verify_authenticity_token
def send_mail
if MessageMailer.new_message(contact_params).deliver
redirect_to contact_path
flash[:notice] = 'Your messages has been sent.'
end
end
private
def contact_params
params.require(:contact).permit(:name, :email, :subject, :content)
end
end
