# Migrations
# Doesn't work
All migrations go into a single file I'll creatively call `migrations`:
## SAD
-- 1 up
CREATE TABLE IF NOT EXISTS pastes (
paste_id SERIAL PRIMARY KEY,
paste_body TEXT
);
-- 1 down
DROP TABLE pastes;
Connect to the database and then apply the migrations:
my $dbh = DBIish.connect:
'Pg',
:host<devbussy.swagg.net>,
:database<pastes_bin>,
:user<pastes_bin>,
password => prompt 'enter DB password: ';
my $m = DB::Migration::Simple.new:
:$dbh,
:migration-file<migrations>;
$m.migrate: :version<1>;
Get prompted for password for now:
$ ./bin/pastes-bin
enter DB password: hogrider69
line: -- 1 up
version: 1, direction: up
line: CREATE TABLE IF NOT EXISTS pastes (
line: paste_id SERIAL PRIMARY KEY,
line: paste_body TEXT
line: );
line: -- 1 down
version: 1, direction: down
line: DROP TABLE pastes;
initializing db-migrations-simple-meta
set initial version to 0
{1 => {down => DROP TABLE pastes;
, up => CREATE TABLE IF NOT EXISTS pastes (
paste_id SERIAL PRIMARY KEY,
paste_body TEXT
);
}}
migrating from version '0' to version '1'
True migrating 'up' from version '0' to version '1'
doing 'up' migrations for 1
executing CREATE TABLE IF NOT EXISTS pastes (
paste_id SERIAL PRIMARY KEY,
paste_body TEXT
)
Humming-Bird listening on port http://localhost:3000
Let's check on DB:
$ psql -h devbussy.swagg.net -U pastes_bin
Password for user pastes_bin:
psql (15.3 (Debian 15.3-0+deb12u1))
SSL connection (protocol: TLSv1.3, cipher: TLS_AES_256_GCM_SHA384, compression: off)
Type "help" for help.

List of relations

public | db-migrations-simple-meta | table | pastes_bin
public | pastes | table | pastes_bin
public | pastes_paste_id_seq | sequence | pastes_bin

pastes_bin=> \d pastes;

Column | Type | Collation | Nullable | Default

paste_id | integer | | not null | nextval('pastes_paste_id_seq'::regclass)
paste_body | text | | |
Indexes:
"pastes_pkey" PRIMARY KEY, btree (paste_id)
Some mock-up 'model' code:
use Pastes-Bin::Model::Paste;
# No routes yet just prompt to 'fake it'
my $new-paste = prompt 'enter a new paste: ';
Pastes-Bin::Model::Paste.create: $new-paste;
Now test it:
$ ./bin/pastes-bin
enter DB password: hogrider69
line: -- 1 up
version: 1, direction: up
line: CREATE TABLE IF NOT EXISTS pastes (
line: paste_id SERIAL PRIMARY KEY,
line: paste_body TEXT
line: );
line: -- 1 down
version: 1, direction: down
line: DROP TABLE pastes;
current-version: allrows: [[1]]
{1 => {down => DROP TABLE pastes;
, up => CREATE TABLE IF NOT EXISTS pastes (
paste_id SERIAL PRIMARY KEY,
paste_body TEXT
);
}}
migrating from version '1' to version '1'
DB already at version 1
enter a new paste: testing 123...
Humming-Bird listening on port http://localhost:3000
^C
Now check the DB for the paste:
pastes_bin=> SELECT * FROM pastes;
paste_id | paste_body
----------+------------
(0 rows)
pastes_bin=> SELECT * FROM pastes;
paste_id | paste_body
----------+----------------
1 | testing 123...
(1 row)
