mongodb.yml for heroku using mongolab

I tried to deploy my new rails app to heroku using mongolab (Only rails framework)

$ rails new myapp --skip-active-record
$ cd myapp

b. Add gems to Gemfile

ruby '2.2.0'
gem 'mongoid', '~> 4', github: 'mongoid/mongoid'
gem 'bson_ext'
group :production do
  gem 'rails_12factor'
end

c. bundle those gems and generate mongoid.yml

$ bundle install
$ rails g mongoid:config

d. config mongoid.yml add/modify production to use mongolab

mongoid.yml

production:
  sessions:
    default:
      uri: <%= ENV['MONGOLAB_URI'] %>

e. Create git and heroku apps

$ git init
$ git add .
$ git commit -am 'Initial Commit'  

$ heroku login
$ heroku apps:create myapp

f. Addons mongolab

$ heroku addons:add mongolab

And mongolab sandbox display:

mongolab sandbox:

To connect using the shell:
mongo ds051831.mongolab.com:51831/heroku_app34606139 -u <dbuser> -p <dbpassword>
To connect using a driver via the standard URI (what's this?):
mongodb://<dbuser>:<dbpassword>@ds051831.mongolab.com:51831/heroku_app34606139

g. Config my addon credential

$ heroku config | grep MONGOLAB_URI

MONGOLAB_URI: mongodb://heroku_app34655737:[email protected]:51831/heroku_app34655737

Then copy from mongodb://......

$ heroku config:add MONGOLAB_URI=mongodb://my_mongolab_user:[email protected]:51831/heroku_app34606139

h. Deploy myapp to heroku

$ git push heroku master

i. Run myapp on heroku

$ heroku open

Problem solved: Above steps are OK

However I will leave my error message below with the fixed for that

The app shown in localhost:3000 ok. But not heroku

Here responsed from heroku screen.

The page you were looking for doesn't exist.

This is heroku logs: at this step

$ heroku logs --tail

routes.rb

Rails.application.routes.draw do

end

Manual create welcome controller and view with routes welcome_controller.rb

class WelcomeController < ApplicationController

  # GET /welcome
  def index

  end

end

Created index.erb in welcome folder at views

<h1>Welcome Rails at heroku</h1>

<p>
   Welcome! Hi 
</p>

At routes.rb set root to welcome

Rails.application.routes.draw do
  resources :projects
  root 'welcome#index'
end

projects_controller.rb

Then git add, commit and push to heroku WORK

Only problem is when I try scaffold. It still error with no clue from logs

$ rails g scaffold Project name:String status:String
$ git add .
$ git commit -am 'scaffold Project'
$ git push heroku master
$ heroku open

Goto https://myapp.herokuapp.com/projects

PROBLEM Display

projects error

When you want to deploy on heroku you must add in your Gemfile :

group :production do
  gem 'rails_12factor'
end

Reference : https://devcenter.heroku.com/articles/getting-started-with-rails4#write-your-app

After testing with your repo you need to delete the options declared on mongoid.yml :

production:
  sessions:
    default:
      uri: <%= ENV['MONGOLAB_URI'] %>

And it's a good practice to declare a ruby version in you Gemfile like :

source 'https://rubygems.org'
ruby "2.1.3"
...

Test it on my heroku app : https://tranquil-woodland-7416.herokuapp.com/projects
