rails assets:precompile RAILS_ENV=productionでエラー

Compiling...

とエラーがでて

この記事にある通り、

package.jsonと
webpack.config.jsを色々書かないと行けない…

でもいまのrails プロジェクトには、webpack.config.js
ファイルは無い。

を１から勉強することにします。

解決できた。。。

.gitignoreに

/public/assets/
を設定していた。。

vueファイルから画像を読み込む際に
assets以下の画像がなぜか読み込めなかったので

public/assets/images/以下に画像を設定していたが、

.gitignoreに

/public/assets/
を設定していたので、commit ,pushできず以上のように本番環境でエラーが起きていた。
くそ単純だった。。
なんか依存関係とかかと思って間違ったアプローチしてた。。。

本番環境でのブラウザで

Webpacker::Manifest::MissingEntryError in Sessions#new
Showing /var/www/coffee_passport/app/views/sessions/new.html.erb where line #3 raised:

Webpacker can't find app_explain in /var/www/coffee_passport/public/packs/manifest.json. Possible causes:
1. You want to set webpacker.yml value of compile to true for your environment
unless you are using the webpack -w or the webpack-dev-server.
2. webpack has not yet re-run to reflect updates.
3. You have misconfigured Webpacker's config/webpacker.yml file.
4. Your webpack configuration is not creating a manifest.
Your manifest contains:

こんなエラー起きていたが、

Webpacker can't find app_explain in /var/www/coffee_passport/public/packs/manifest.json. Possible causes:

とある。

/var/www/coffee_passport/public/packs/manifest.json.

もgit ignoreにしてるのでそりゃそうだ。。。

/public/packs
/public/packs-test

をはずした。。

めっちゃコミット対象のファイルが増えた。。。1000ファイルくらい。。まぁいいや。

rails assets:precompile RAILS_ENV=production

も上手くいった。

解決できたと思ったが、

スクリーンショット 2021-09-08 17.58.28.png

だが本番環境のブラウザで
でvueファイルが読み込まれてない。。。

ちゃんと production.rbは

config.assets.compile = true

になってる。

/public/assets/express
もgit ignoreから削除

var finalhandler = require('finalhandler');
var Router = require('./router');
var methods = require('methods');
var middleware = require('./middleware/init');
var query = require('./middleware/query');
var debug = require('debug')('express:application');
var View = require('./view');
var http = require('http');
var compileETag = require('./utils').compileETag;
var compileQueryParser = require('./utils').compileQueryParser;
var compileTrust = require('./utils').compileTrust;
var deprecate = require('depd')('express');
var flatten = require('array-flatten');
var merge = require('utils-merge');
var resolve = require('path').resolve;
var setPrototypeOf = require('setprototypeof')
var slice = Array.prototype.slice;

こういった大事そうな記述をignoreしちゃってたからね。

再度、git pull
やrails assets:precompile RAILS_ENV=production
を実行して以上なかったが、

やっぱりさっきのエラーになる。

Routing Error
No route matches [GET] "/logout"

あとついでに本番環境のrailsのほうでエラーが起きた。
なんで、ｊｓ関係ないやろ。。。

route.rb
  delete '/logout',  to: 'sessions#destroy'
app/views/users/config.html.erb

  <div class="user-config-child">
    <%= link_to "ログアウト", "/logout",method: :delete,data: {confirm: "本当にログア
ウトしますか？"} %>
  </div>

とエラーが表示された。。。
なんで。。。
getリクエストになってるの。。。

同じことに悩んでるひといた。

なるほど、js関係あるのか。。。

jsが上手く動作しないと、deleteやpostが正常に動作しないっぽい。。。

まずはEC2インスタンスを再起動

してもだめだった。。。

さっき、js関係のファイルをcommitして、pushしたから
それが原因とかしらんぞ。。。

application.js

// This file is automatically compiled by Webpack, along with any other files
// present in this directory. You're encouraged to place your actual application logic in
// a relevant structure within app/javascript and only use these pack files to reference
// that code so it'll be compiled.

require("@rails/ujs").start()
// require("turbolinks").start()
require("@rails/activestorage").start()
require("channels")
require("../bgswitcher")
require("../card")
require("./tag")
require("../slide")
require('./preview') 
//= require rails-ujs
config/webpacker.yml


production:
  <<: *default

  # Production depends on precompilation of packs prior to booting for performance.
  compile: true

  # Extract and emit a css file
  extract_css: true

  # Cache manifest.json for performance
  cache_manifest: true

の

compile: trueに変更。

し、git pull と　rails assets:precompile RAILS_ENV=productionを実行
上手くいった。

それでも
Failed to load resource: the server responded with a status of 404 (Not Found)

となった。。

$ git rm --cached -r 削除したいディレクトリ

$ git rm --cached ファイル名

らしいので、

git rm --cached -r public/assets/express

git rm --cached -r public/packs/js

を実行して

だけどエラーは変わらず。

git rm --cached -r public/packs/media/images

rm 'public/packs/media/images/coffee_gif-2c7fb49d.gif'
rm 'public/packs/media/images/coffee_gif-d678c3db.gif'

rm 'public/packs/media/images/sold_item4-2189bb94.png'
rm 'public/packs/media/images/sold_item4-fb614d95.png'

これも機械的に生成されるファイルをっぽいのでgit ignoreにしてみた。

スクリーンショット 2021-09-08 21.26.11.png

ハッシュ値的なものがついたファイルをgit ignoreに設定したけど、
この画像を見る限りは、ハッシュ値的なのがついてるのをリクエストしてるからやっぱりgit ignoreしないほうがいいかも

okuramasafumiさんから

機械的に生成されたファイルをコミットすると、それらの生成元となったファイルが変更されるたびに生成後のファイルもコミットしなくてはならなくなってしまいますね。
「機械的に生成」するタイミングをデプロイの最中にすれば、それらファイルをコミットせずに本番環境に配置できますね。

と教えてもらった。

まぁでも機械的に生成されるファイルは必要そう。
だけども、それらの生成元となったファイルが変更されるたびに生成後のファイルもコミットしなくてはならなくなってしまう。

いったんアプリが動くようになってから

「機械的に生成」するタイミングをデプロイの最中にする設定にしよう。
