PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

-E: will describe the underlaying queries of the \ commands (cool for learning!)
-l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

Rails Generating & Scaffolding

Rails' use of strict naming conventions means a lot of core code SHOULD be in the same format whoever writes it? It could be written by a friend, colleague or a computer... it shouldn't matter because the same Rails rules apply to everyone.

This means that Rails can actually do some tasks for you! It can actually build things and write code on your behalf...

Coming from another language like PHP, this can seem like magic.

Nginx FastCGI response buffer sizes

By default when Nginx starts receiving a response from a FastCGI backend (such as PHP-FPM) it will buffer the response in memory before delivering it to the client. Any response larger than the set buffer size is saved to a temporary file on disk.

This process is outlined at the Nginx ngx_http_fastcgi_module page manual page.

Determine actual FastCGI response sizes
Setting the buffer size

Our Git Flow

We are using a simple git flow based on git flow and github flow. We have two branches develop and master.

develop is a representation of staging

master is a representation of production

	cd my_heroku_app

	# Make sure DB doesn't update on Heroku. This may be enough depending on your needs.
	heroku maintenance:on

	# Dump from Heroku.
	heroku pg:pull DATABASE_URL heroku_dump
	pg_dump heroku_dump -Fc > /tmp/db.dump # Fc for binary dump (otherwise the import will complain)

	# Restore to Dokku.
