There are two types of markup in Liquid: Output and Tag.

Output markup (which may resolve to text) is surrounded by

{{ matched pairs of curly brackets (ie, braces) }}

Tag markup (which cannot resolve to text) is surrounded by

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h):

-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)

Active Record

É um design pattern que o Rails implementa a partir da gem ActiveRecord.

Serve para conectar a camada Model da aplicação com tabelas do database, para assim criar um modelo de domínio persistível, onde a lógica (Model) e dados (BD) são apresentados em uma única solução.

Já persiste no BD:

obj.create

	$data = curl_exec($ch);

	$json = json_decode($data);

	echo "<pre>TLS version: " . $json->tls_version . "</pre>\n";
