If you're writing web applications with Ruby there comes a time when you might need something a lot simpler, or even faster, than Ruby on Rails or the Sinatra micro-framework. Enter Rack.
Rack describes itself as follows:
Rack provides a minimal interface between webservers supporting Ruby and Ruby frameworks.
Before Rack came along Ruby web frameworks all implemented their own interfaces, which made it incredibly difficult to write web servers for them, or to share code between two different frameworks. Now almost all Ruby web frameworks implement Rack, including Rails and Sinatra, meaning that these applications can now behave in a similar fashion to one another.
At it's core Rack provides a great set of tools to allow you to build the most simple web application or interface you can. Rack applications can be written in a single line of code. But we're getting ahead of ourselves a bit.
// === Arrays | |
var [a, b] = [1, 2]; | |
console.log(a, b); | |
//=> 1 2 | |
// Use from functions, only select from pattern | |
var foo = () => [1, 2, 3]; |
It's important to note that running this reset will drop any existing data you have in the application
heroku restart
heroku pg:reset DATABASE
(no need to change the DATABASE
)heroku run rake db:migrate
heroku run rake db:seed
(if you have seed)One liner

docker exec -i "${DOCKER_DB_NAME}" pg_restore -C --clean --no-acl --no-owner -U "${DB_USER}" -d "${DB_HOSTNAME}" < "${LOCAL_DUMP_PATH}" | |
