こんにちは、 .ごっちです。
Railsのプロダクトにいろいろ技術的な挑戦をするために様々とりいれているのですが、少し前にElasticsearchを入れました。
このときは5系だったのですが、7系の最新バージョンにアップグレードしたというお話です。
参考
7系の参考は↑です。
ざっくり開発環境でのアップグレード方法
公式ページからファイルを落としてきます。
起動します。
./elasticsearch-7.1.0/bin/elasticsearchkuromojiいれます。
$ ./elasticsearch-7.1.0/bin/elasticsearch-plugin install analysis-kuromoji
-> Downloading analysis-kuromoji from elastic

-> Installed analysis-kuromojiGemfile のelasticsearch-rails, elasticsearch-modelのバージョン指定の部分を削除します。
bundle install します。
importします。
$ bin/rails elasticsearch:create_weapon_index

Tasks: TOP => elasticsearch:create_weapon_index
(See full trace by running task with --trace)なんかエラッたのでindexの修正をします。
# app/models/concerns/weapon_searchable.rb
mappings dynamic: 'false' do
indexes 'name', analyzer: 'kuromoji_analyzer'
endこれでインポートタスクを実行させると無事に完了します。
これに合わせてテストやCircleCIの設定も変更しています。
詳しい差分はしたのPRを見てください。
そんなこんなで動かしてみたお話でした。このくらいの規模ならいらないといえばいらないんですが念の為。。
