###試したこと
|
|
576
|
+
|
|
577
|
+
**1、`rails db:create RAILS_ENV=production`を実行する**
|
|
578
|
+
|
|
579
|
+
|
|
580
|
+
|
|
581
|
+
実行した結果は前述の通りです。
|
|
582
|
+
|
|
583
|
+
|
|
584
|
+
|
|
585
|
+
**2、マスターキー**
|
|
586
|
+
|
|
587
|
+
|
|
588
|
+
|
|
589
|
+
"**config直下にmaster.keyがないです**"みたいなエラーが出たこともあって、今は配置済みです。
|
|
590
|
+
|
|
591
|
+
正直そこも、記事によって書いてあることが違う▼のがよくわからないのですが…
|
|
592
|
+
|
|
593
|
+
|
|
594
|
+
|
|
595
|
+
- アプリ/config/master.key
|
|
596
|
+
|
|
597
|
+
- アプリ/shared/config/master.key
|
|
598
|
+
|
|
599
|
+
|
|
600
|
+
|
|
601
|
+
最初は`shared/config`にマスターキーを置いていました。
|
|
602
|
+
|
|
603
|
+
今はアプリ直下の`config`にも配置してあり、本番環境にマスターキーが二つある状態です。
|
|
604
|
+
|
|
605
|
+
（これもエラーの原因になるのでしょうか？）
|
|
606
|
+
|
|
607
|
+
|
|
608
|
+
|
|
609
|
+
|
|
610
|
+
|
|
611
|
+
**3、`production.rb`に追記したコードを削除**
|
|
612
|
+
|
|
613
|
+
|
|
614
|
+
|
|
615
|
+
```
|
|
616
|
+
|
|
617
|
+
set :linked_files, fetch(:linked_files, []).push("config/master.key")
|
|
618
|
+
|
|
619
|
+
```
|
|
620
