Heroku in Rails - set up and debugging

```bash
'rails new APPNAME --database=postgresql’
*heroku doesn’t use sqlite3, which is default in new rails apps
***SQLite just stores the database to a file in your db/ folder, which is why it's incompatible with Heroku.***

**Redo blog app using postgresql DB
**Then try deploying to heroku


How to deploy app to heroku
=======================
heroku login (to login)


Need to init a local git repo first 
cd myapp
git init
git add .
git commit -m “my first commit”

Create heroku remote
heroku create
git remote -v (to verify - see desired output below)
git push heroku master

heroku run rake db:seed
heroku run rake db:migrate
heroku open
```

***Can only deploy from master***
**to push a branch other than master:
 git push heroku yourbranch:master**
 
 ###Add a remote to an existing git repo
 heroku git:remote -a falling-wind-1624
Git remote heroku added.

ERROR SITUATION

Execute this:
$ rake assets:precompile
$ git add .
$ git commit -m "Add precompiled assets for Heroku"
$ git push heroku master
 git remote -v
heroku  https://git.heroku.com/falling-wind-1624.git (fetch)
heroku  https://git.heroku.com/falling-wind-1624.git (push)
