Squirm is a database library that facilitates working with Postgres and stored procedures.
Squirm is not stable yet. Feel free to play around with it, but unless you want to contribute to its development, you probably shouldn't use it for anything sensitive.
It currently provides:
- A basic connection pool
- A little syntactic sugar around the pg gem
- Class for accessing stored procedures as if they were Ruby procs
Here's a quick demo of how you might use it:
-- Your database CREATE TABLE "users" ( "name" VARCHAR(256), "email" VARCHAR(64) NOT NULL UNIQUE ); CREATE SCHEMA "users"; CREATE FUNCTION "users"."create"(_email text, _name text) RETURNS integer AS $$ DECLARE new_id integer; BEGIN INSERT INTO "users" (email, name) VALUES (_email, _name) RETURNING id INTO new_id; IF FOUND THEN RETURN new_id; END IF; END; $$ LANGUAGE 'plpgsql'; Squirm.connect dbname: "your_database" create = Squirm::Procedure.new("create", schema: "users") id = create.call(email: "[email protected]", name: "John Doe")
In and of itself, Squirm offers very little, but is meant to be a basic building block for other libraries, such as Squirm Rails, which adds stored procedure support to Active Record, or Squirm Model, which supplies an Active Model compatible ORM based on stored procedures.
