Rails Website Login not working in production (Heroku)

Question

I am creating a Rails application containing a Login. In development everything is fine. Login in production (Heroku) fails.

As I am new to RoR I follow this Basic Tutorial . The App contains a "User" model. The user has a boolean attribute "activated" as an account needs to be activated after the signup. During login there is an statement (see sessions_controller.rb):

if user.activated?

which is true in development and false in production.

I pushed the database with seeds.rb. On other pages I can see content, also initialized with seeds.rb, so I think it is no general database issue.

As the databese seems to be okay and it runs in development I assume I just missed something, which is hard to detect for me as a newbie and hopefully easy to detect for an experienced programmer.

Here is a part of my code. Say if you need more.

sessions_controller.rb:

def create
user = User.find_by(email: params[:session][:email].downcase)
if user && user.authenticate(params[:session][:password])
  if user.activated?
    log_in user
    params[:session][:remember_me] == '1' ? remember(user) : forget(user)
    redirect_to changenews_path
  else
    message  = "Account not activated. "
    message += "Check your email for the activation link."
    flash[:warning] = message
    redirect_to root_url
  end
else
  flash.now[:danger] = 'Invalid email/password combination'
  render 'new'
end
end

This checks if the user who is logging in is already activated. In production it leads to "else > message [...]".

my Gemfile:

source 'https://rubygems.org'

gem 'rails',        ' 5.1.6'
gem 'bootstrap', ' 4.2.1'
gem 'puma',         ' 3.9.1'

  gem 'guard',                    '2.13.0'
  gem 'guard-minitest',           '2.4.4'
end

group :production do
  gem 'pg', '0.18.4'
end

# Windows does not include zoneinfo files, so bundle the tzinfo-data gem
gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]

I tried to set all gems to the latest version ('>= XYZ') and do "bundle install", but there was no effect.

and the Heroku log (extract):

:23.352114+00:00 app[web.1]: I, [:23.352005 #4]  INFO -- : [shortened] Started POST "/login" for 77.183.95.212 at 2019-04-09 11:43:23 +0000

:23.432392+00:00 app[web.1]: I, [:23.432248 #4]  INFO -- : [shortened] Redirected to https://myappname.herokuapp.com/

I can't get any information from the debug message. And i I have no clue what the "LIMIT" stands for. I hope someone of you knows an answer to my problem.

So usually I expect the login to be successful, as the database seems to be okay. Currently user.activated? ist false in Heroku.

Thanks in advance!

Answer 1

1. Heroku runs bundle install when you push the code so you dont need to run this.

2. Did you run heroku run db:seed to actually seed your database?

3. If you did, you can run heroku run rails c , then u = User.all and manually check by looking at the output that the users have correctly been seeded.

4. (opinion) I would suggest using the "devise" gem for users/logins etc.. but feel free to use whatever you are more confortable with.

5. Please use the heroku logs to give us (and yourself) a better understanding of what is wrong by running heroku logs -n 200 , 200 being the number of lines to display.
