Routing error in heroku app after deployment with git push command

Routing error in heroku app after deployment with git push command - ruby-on-rails

I am at chapter 3 of Michael Hartl's tutorial but when I do git push heroku master and it says that it has been deployed to heroku successfully but when I go to the url: http://young-thicket-2043.herokuapp.com/ it says that the app cannot be seen.
I've checked out heroku logs and this was given:

Can anyone shed some light on this?

If you look at your logs you can see
ActionController::RoutingError (No route matches [GET] "/")
Which basically means that you don't have any root route setup in your routes.rb. Inside your routes.rb add this line:
root 'pages#show'
By writing this you are setting your root route to Page Controllers show action

How to solve the [GET] "/login" routing error while building shopify app using ruby on rails?

I am getting a Routing error says " no routes matches [GET] "/login" " and also in ruby libraries. During running on a server it displays page not found and the logs for that error is Logs show [GET] route error and library error.
I have my index file at following path
views/home/index.html.erb
My code in config/routes.rb is:
Rails.application.routes.draw do
root 'home#index'
get 'show' => 'welcomes#show'
resources :home
I am working on this app for the last 10 days with the same route and ruby version without an error but now this error came from nowhere.
I am using heroku as my intermediate server.

There is no any route for /login in your config/routes.rb code. I guess you should define one.

Page not displaying on heroku - heroku[router]: status = 500

Could one advise me on how to correct this error, i have no clue and i have tried all helps from other pages on stackoverflow.
i have tried all the below recommended suggestions by others:
suggestion1: log entries
gem 'rails_12factor'
changing config.log_level = :debug
rake db:migrate
heroku config:set
but i am unsure why i get the below error. Your help and advise would be much appreciated.

It looks to be a database error which typically happens when you only run migrations on your local and forget to run migrations on the heroku
box. Run
heroku run rake db:migrate
to run migrations on your deployed box after you've pushed your latest git commit to it.

This has been resolved. Thank you to everyone
This was due to restricted access to the database using heroku.
I was on the heroku DATABASE_URL which permitted a maximum on 10'000 rows of code. i had 10'891 rows of code
to find out more on your pg database, type: heroku pg:info --app yourAppName
i had to upgrade [in the admin panel] to HEROKU_POSTGRESQL_GOLD_URL or you can simply type in the terminal heroku pg:upgrade HEROKU_POSTGRESQL_GOLD --app yourAppName
before you upgrade ensure maintenance is on. in the terminal type: heroku maintenance:on
new database url i selected is currently $9/mth - this permits more rows of code
once you've upgraded in the terminal, type: heroku pg:promote HEROKU_POSTGRESQL_GOLD to set it as the default database
if you currently have data stored in the previous, type: heroku pg:copy DATABASE_URL HEROKU_POSTGRESQL_GOLD --app yourAppName to transfer data

Ruby on Rails app in Cloud9 "doesn't exist" on Heroku

I'm working on my first Rails app. I'm in Windows, so I'm building it in Cloud9, and I deployed it to Heroku. In my Heroku dashboard, the app appears to be fine, but the app page gives me the message: The page you were looking for doesn't exist. After some searching, it seemed like I needed to run heroku run rake db:migrate to migrate the database, but that doesn't help.
Here are my Heroku logs:
heroku-cli: This CLI is deprecated. Please reinstall from https://cli.heroku.com

Any suggestions?

I think you need to compile your asset,
you can do this in your
config/environments/production.rb file:
Please change this
config.assets.compile = true
It will be very helpful if you post log from heroku.

run
$ rake secret
and then paste the output string in config/initializers/secret_token.rb
MyAppNAME_GOES_HERE::Application.config.secret_key_base = 'e5d6fed054aadcb955c17d90ab0cae35b9921e3af7fa0f88ba2b8bcee6ab1b087e34c2081c867b42093f81197bd4272c49a2337fc7d31b6f892ae6ef57e842d7'
now commit & push all changes to heroku.
PS: Instead of harder-coded secret_key_base, it makes more sense from security prespective to set this a ENV var on heroku, like this:
$ heroku config:set SECRET_KEY_BASE=that_random_string_goes_here
for more details on how to do this, check this. But if you just getting starting started, you can learn how to do this later & this hard-coded will workout any problems

Never place the secret key in the config/initializers/secret_token.rb file directly.
It is a security threat always
Instead create an ENV variable as
MyAppNAME_GOES_HERE::Application.config.secret_key_base = ENV[SECRET_KEY]
and place the SECRET_KEY in heroku setting under Heroku login >> under_app >> setting >> reveal config vars
and finally restart your application

Deployed Scaffold rails app to Heroku. "heroku open" gives "page you were looking for doesn't exist"

Windows 7, re-installed latest rails version from railsinstaller.org today.
"heroku push" was successful.
db migration successful.
"heroku open" gives "page you were looking for doesn't exist"
I've deployed before using Rails 4 and didn't have any problems. Just today.
Please help!
Thanks

It doesn't look like you have an error - just that you haven't set a route for the root. ie. something like this in routes.rb root 'home#index'.
PS. Note that Rails 4 does something weird in production - it behaves differently to development mode, and expects an explicit root route defined.
