準備

プロジェクトディレクトリ作成移動バージョン確認

new

% rails new . -d postgresql --css tailwind

daisyui

tailwind css UIコンポーネント　インストール

% yarn add daisyui

データベース移行

Herokuからdumpしてローカルにheroku_dumpデータベースを新設しリストアする

$ heroku pg:backups:capture
$ heroku pg:backups:download
$ createdb mydb
$ pg_restore --verbose --clean --no-acl --no-owner -h localhost -U myuser -d mydb latest.dump

作り直すアプリはデータベース構造を変えるのでテーブルごとにダンプ・リストアする

データ数確認

=# select count(*) from clients ;
 count 
-------
  5067
(1 row)

heroku_dumpデータベースでテーブル名を変える

テーブル毎に変える

=# ALTER TABLE users RENAME TO users_old;
=# ALTER TABLE clients RENAME TO clients_old;

旧テーブルダンプ

テーブル毎にダンプする

% pg_dump --username=jq --table users_old heroku_dump > users_old.sql

旧テーブルをセレクトして新テーブルにインサートする

=# insert into users
(
    id, name, email, created_at, updated_at, password_digest, remember_digest, activation_digest, activated, activated_at, reset_digest, reset_sent_at
)
select
    id, name, email, created_at, updated_at, password_digest, remember_digest, activation_digest, activated, activated_at, reset_digest, reset_sent_at
from
    users_old;
INSERT 0 17

select

    jiins;
INSERT 0 14

clientsテーブルにインサートする

旧clientsテーブルをclientsとotherに分ける

新clientsテーブルは代表者名テーブルになる　旧clientsテーブルのnusiをセレクトして新clientsテーブルにインサートする　nusiのie_idを新clientsテーブルのidにする　その前にie_idの重複を修正する

重複確認

=# SELECT ie_id, COUNT(ie_id)
FROM clients_old
where nusi = true GROUP BY ie_id
HAVING COUNT(ie_id) > 1
ORDER BY ie_id;
 ie_id | count 
-------+-------
  2090 |     2
  2129 |     2
  2167 |     2
  2174 |     2

桁数を変えて重複を解消する

=# update clients_old SET ie_id = ie_id + 20000 where jiin_id = 2;
UPDATE 776
=# update clients_old SET ie_id = ie_id + 30000 where jiin_id = 3;
UPDATE 790
=# update clients_old SET ie_id = ie_id + 40000 where jiin_id = 4;
UPDATE 307

主重複修正

=# update clients_old set nusi = false where id = 3703;
=# update clients_old set nusi = false where id = 1346;

不要データ削除

=# delete from clients_old where id in (4028,3911,3912,2998,3007,4359);

nusiをセレクトして新clientsにインサート

=# insert into clients
(
    id, user_id, note_id, content, client_line, created_at, updated_at
)
select
    ie_id, user_id, jiin_id, name, table_order,  created_at, updated_at
from
    clients_old
where
    nusi = true;
INSERT 0 1292

UUIDを有効にする

% rails generate migration enable_extension_for_uuid

migrate編集

class EnableExtensionForUuid < ActiveRecord::Migration[7.0]
  def change                   
    enable_extension 'pgcrypto' unless extension_enabled?('pgcrypto')
  end
end

% rails db:migrate

デフォルトのキーをuuidにする

config/initializers/generators.rb 作成

Rails.application.config.generators do |g|
  g.orm :active_record, primary_key_type: :uuid
end

generate

$ rails generate scaffold User name:string email:string password_digest:string remember_digest:string role:integer activation_digest:string activated:boolean activated_at:datetime reset_digest:string reset_sent_at:datetime

migrationファイルを確認　indexを書く　以下同じ

% rails generate scaffold Note user:references content:string kind:integer meeting_time:integer role:integer note_line:integer

% rails generate scaffold List user:references note:references content:string list_line:integer

% rails generate scaffold Client user:references note:references list:references content:string client_line:integer memo:text

% rails generate scaffold Other user:references note:references client:references name:string kana:string client_name:boolean other_line:integer memo:text generation:string

やり直し
% rails destroy scaffold User .................

$ rails generate scaffold Post content:text user:references picture:string

$ rails generate model Relationship follower_id:integer followed_id:integer

$ rails db:migrate RAILS_ENV=production

$ bin/dev

$ rails generate controller StaticPages home help about contact
