I am fairly new to rails/heroku, so any help is much appreciated. I am trying to deploy after alot of development. For the future, is it better to push to heroku early in the development process and then keep pushing as you go? Thanks!

Answer 1

1. ActiveRecord::StatementInvalid (PG::Error: ERROR: relation "houses" does not exist .

   I would say the houses table in database is missing, you can run migrations using heroku toolbelt: heroku run rake db:create --app my_app2 - to create the database, heroku run rake db:migrate --app my_app2 - to run migrations. Setting up a deploy with Capistrano will run all the things for you with one command.

   Heroku Toolbelt - https://toolbelt.heroku.com/

   Capistrano - https://github.com/capistrano/capistrano

2. For the future, is it better to push to heroku early in the development process and then keep pushing as you go?

   At the project I am currently working with our team, we have 2 instances of heroku , means 2 apps, one is for production , the second for testing , changes are pushed to testing app first and if all goes well we move it to production.

Edit

As I found out your are using sqlite for development:

Heroku uses postgresql. https://devcenter.heroku.com/articles/sqlite3

Remove sqlite3 or move it into a development group in your Gemfile like this:

group :development do
  gem 'sqlite3'
end

group :production do
  gem 'thin'
  gem 'pg'
end

remove Gemfile.lock run bundle install --without production

git add .
git commit -am "bundle updating sqlite3"
git push heroku master

or easier, just use PG on your local computer for development. You might have some sql statements that will work in sqlite and will not work in postgres on heroku, so in your place I would use PG on development.
