対処法
PG::DuplicateTable: ERROR: relation "tweets" already existsという記載から、tweetsというテーブルが既に存在していることがわかる。
原因はデータベースにテーブルが消したテーブルが残っていたのが原因。
$ rails db:migrate:reset Dropped database 'kinoko2_test' Created database 'kinoko2_development' Created database 'kinoko2_test' == 20210514015843 CreateTweets: migrating ===================================== -- create_table(:tweets) -> 0.0352s == 20210514015843 CreateTweets: migrated (0.0353s) ============================
を実行することでデータベースをdropされ、新たにテーブルがcreateされる。
これによりDBがリセットされて、rails db:migrateすることでエラーが解消される。

<Ruby on Rails エラー編> mimemagicのbundle installエラーについて
エラーについて
mimemagicがbundle installできなくなった。
2021年3月下旬、twitterなどで大騒ぎになった。
大元が誤ったライセンスのもと配布していたようで、MITで配布していたが、実際はmimemagicの中のファイルがshared-mime-infoに依存しているためライセンスはGPLということになって修正が入り、ActiveRecordがmimemagicに依存していたため、buildができない大混乱が生じた、ということらしい？
数日後該当のファイルを削除してMITに戻ったらしいが、その代わりGPLのshared-mime-infoのインストールを自分で行わないといけなくなったということらしい。
Rails 5.2.5, 6.0.3.6, 6.1.3.1に関してはmimemagicの依存がなくなったとのことで、問題はなくなったよう。
対処法
Rails 5.2.5以前のものはmimemagicが依存しているため、別途shared-mime-infoをインストールする必要がある。
$ brew install shared-mime-info

対処
デフォルトでセットされているSpringは、アプリケーションをバックグラウンドで動作させることで、開発を高速化するgem。
見たところspringが動いているので、プロセスを確認。
$ ps aux | grep -i spring user_name 5264 0.0 0.0 4387048 2056 ?? S 4:11PM 0:01.33 spring server | kinoko2 | started 11 hours ago user_name 32697 0.0 0.0 4279688 764 s002 S+ 4:50AM 0:00.01 grep --color=auto --exclude-dir=.bzr --exclude-dir=CVS --exclude-dir=.git --exclude-dir=.hg --exclude-dir=.svn --exclude-dir=.idea --exclude-dir=.tox -i spring
springをkillする。
$ kill -9 5264
rails consoleを実行したところ、動いた。

やったこと
まず、postgreSQLが動作しているかを確認する。
$ brew services list mysql@5.7 stopped postgresql error user_name /Users/user_name/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
エラーが発生していて、起動できていないことが確認できた。
一応upgradeを一度して、改めてパスを通した。
$ brew upgrade postgresql $ echo 'export PATH="/usr/local/opt/icu4c/bin:$PATH"' >> ~/.zshrc $ source ~/.zshrc
upgradeした時にpostgresqlの起動方法が表示されているので、
To have launchd start postgresql now and restart at login: brew services start postgresql Or, if you don't want/need a background service you can just run: pg_ctl -D /usr/local/var/postgres start
のうち、
$ pg_ctl -D /usr/local/var/postgres start
起動を実行した。
waiting for server to start....2021-05-13 00:13:14.089 JST [24927] LOG: starting PostgreSQL 13.2 on x86_64-apple-darwin20.3.0, compiled by Apple clang version 12.0.0 (clang-1200.0.32.29), 64-bit 2021-05-13 00:13:14.091 JST [24927] LOG: listening on IPv4 address "127.0.0.1", port 5432 2021-05-13 00:13:14.091 JST [24927] LOG: listening on IPv6 address "::1", port 5432 2021-05-13 00:13:14.107 JST [24927] FATAL: could not create lock file "/tmp/.s.PGSQL.5432.lock": Permission denied 2021-05-13 00:13:14.109 JST [24927] LOG: database system is shut down stopped waiting pg_ctl: could not start server Examine the log output.
すると上記のような表示が出力され、tmpディレクトリにpermission deniedが発生していることがわかった。
そのため、以下のコマンドで許可を与えた。
$ sudo chmod 1777 /tmp
そしてもう一度
$ pg_ctl -D /usr/local/var/postgres start
を実行した。
すると以下のような表示が出た。
pg_ctl: another server might be running; trying to start server anyway waiting for server to start....2021-05-13 00:17:46.861 JST [25470] FATAL: lock file "postmaster.pid" already exists 2021-05-13 00:17:46.861 JST [25470] HINT: Is another postmaster (PID 25460) running in data directory "/usr/local/var/postgres"? stopped waiting pg_ctl: could not start server Examine the log output.
今度はlock file "postmaster.pid" already existsという表示が出たのでrmした。
$ rm /usr/local/var/postgres/postmaster.pid
brew services listで動作確認をまた行うと、
Name Status User Plist mysql@5.7 stopped postgresql started user_name /Users/user_name/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
で動作確認ができ、rails db:createも実行できるようになった。

<Ruby on Rails> credentials.yml.encの設定方法
credentialsとは
production環境用の秘密情報の管理をするためにRails5.2でcredentialsという機能が追加された。
これが導入されるまでは環境変数などで設定されていた。
credentialsは、管理される秘密情報そのものを指すと同時に、管理の仕組みを指す言葉である。
この仕組みを簡単に説明すると、credentials.yml.encファイルに記載された情報を暗号化し、master.keyで複合し、使用できるようにしたもの。
credentials.yml.enc
秘密情報(credentials)は、config/credentials.yml.encに記述する。
このファイルは常に暗号化して保存され、このファイルの内容を編集するには専用コマンドを使用する。
複合はmaster.keyファイルなどからキー情報を取り出して行われる。
※1のp280を参照
基本的に同一のリポジトリにcredentialsファイルとmaster.keyファイルを一緒に置かないこと(復号できてしまうので)。
Railsアプリケーションは、.gitignoreに最初からconfig/master.keyが記述されており、pushされないようになっている。
中身を見るコマンド
$ bin/rails credentials:show
編集するコマンド
$ bin/rails credentials:edit
EDITOR環境変数が設定されていないと、以下のような記載が必要になる。
例：vimの場合
$ EDITOR=vi bin/rails credentials:edit
ちなみにEDITOR環境変数は以下のように設定できる。
$ echo 'export EDITOR=vi' >> ~/.zshrc // 環境変数EDITORを設定 $ source ~/.zshrc // 環境設定ファイル~/.zshrcの内容を反映させる
アプリケーションからcredentialsを参照
例：デフォルトのAWSを参照する
$ Rails.application.credentials.aws
=> {:access_key_id=>123, :secret_access_key=>345}
$ Rails.application.credentials.aws[:access_key_id]
=>123
$ Rails.application.credentials.aws[:secret_access_key]
=>345

<VSC> draw.io拡張機能
<JavaScript> jQueryのメソッド、イベントについて
主要なメソッド
on
例：liタグをクリックすると、アラートが発生する
<body> <div> <li>あああ</li> </div> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script> <script src="script.js"></script> </body>
$("li").on("click", () => {
window.alert("clickされた");
});
fadeout
例：liタグをクリックするとゆっくり消える
<body> <div> <li>クリックされると消えるよ</li> </div> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script> <script src="script.js"></script> </body>
$("li").click(() => {
$("li").fadeOut("slow");
});
fadein
例：clickしてくださいを押すとボックスが表示される
<style> span { cursor: pointer; } div { margin: 3px; width: 80px; display: none; height: 80px; float: left; } #one { background-color: aqua; } #two { background-color: pink; } #three { background-color: yellow; } </style> <body> <span>clickしてください</span> <div id="one"></div> <div id="two"></div> <div id="three"></div> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script> <script src="script.js"></script> </body>
$(document.body).click(() => {
$("div:hidden").first().fadeIn("slow");
});
イベント
「〜をクリックした時」「〜にマウスのカーソルをのせた時」など
「〜をした時」に「〜の処理をする」というもの
イベントの書き方
$(function(){
$("セクレタ").イベント(function{ // セクレタ1を〇〇(=イベント)をした時の部分
$("セレクタ2").メソッド(引数); // セレクタ2に対して××(=イベント)をした時の部分
});
});
覚えておきたいイベント
<!DOCTYPE html> <html lang="ja"> <head> <meta charset="UTF-8" /> <meta http-equiv="X-UA-Compatible" content="IE=edge" /> <meta name="viewport" content="width=device-width, initial-scale=1.0" /> <title>Document</title> <style> div { height: 50px; width: 50px; text-align: center; line-height: 50px; } .box1, .box4 { background-color: silver; } .box2, .box5 { background-color: aquamarine; } .box3, .box6 { background-color: blue; } </style> </head> <body> <div class="box1">1</div> <div class="box2">2</div> <div class="box3">3</div> <div class="box4">4</div> <div class="box5">5</div> <div class="box6">6</div> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script> <script> $(function () { $(".box1").click(function () { $(".box2").hide(); $(".box3").hide(); $(".box4").hide(); $(".box5").hide(); $(".box6").hide(); }); }); </script> </body> </html>
hoverイベント
hover(ホバー)イベントとは、mouseoverとmouseoutの2つを組み合わせたような処理ができるイベント
基本的な記述方法
$(function () {
$("セレクタ").hover(
function () {}, // マウスをのせた時の処理部分
function () {} // マウスを外した時の処理部分
);
});
<body> <p>画像を表示</p> <img src="https://picsum.photos/200/300" /> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script> <script> $(function () { $("p").hover( function () { $("img").fadeIn(); }, function () { $("img").fadeOut(); } ); }); </script> </body>
<body> <div class="abc"> <img src="https://picsum.photos/200/300" /> <img src="https://picsum.photos/200/300" /> <img src="https://picsum.photos/200/300" /> </div> <img src="https://picsum.photos/200/300" /> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script> <script> $(function () { $("img").hover( function () { $(this).animate({ width: "220px" }); }, function () { $(this).animate({ width: "200px" }); } ); }); </script> </body>

<Ruby on Rails エラー編> rails -vをすると大量にignoring nokogiriが吐き出された
発生したエラー
railsをnewした後bundle installし、ふとrails -vを押してみたら大量のignoring nokogiri ~というエラーが出た
$ rails -v Ignoring nokogiri-1.10.9 because its extensions are not built. Try: gem pristine nokogiri --version 1.10.9 ...大量に発生
解決方法
なんでそんなことになったのか分からず、調べてみると以下の記事を発見。
ライブラリがおかしくなっていたようで、一度rbenvをuninstallしてみると解決した。
$ rbenv uninstall 2.6.6 rbenv: remove /Users/user_name/.rbenv/versions/2.6.6?

以下の記述については、いらないファイルが存在しているということらしいので、rmすれば良いらしい。
ちょっと怖いのでmvでゴミ箱へ飛ばした。
rbenv: cannot rehash: /Users/user_name/.rbenv/shims/.rbenv-shim exists

<JavaScript> jQueryの基本構文、セクレタについて
jQueryとは
JavaScriptのコードを簡単に使えるようにしたライブラリ(コード集)。 使用するとwebページにさまざまな動きを加えることができる。
使用方法
・jQueryファイル(CDN：Contents Delivery Network)を読み込んで使用
・jQueryファイルをダウンロードして使用
記載する場所はheadタグ内か、bodyの締めの手前。
最近はbody前が多い、らしい。
先にjqueryのCDNを読ませないとscriptが使用できないので注意する。
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script> <script type="text/javascript" src="script.js"></script>
script タグの type="text/javascript" の有無による違い
※上記記事で、html5以降ではtype指定が不要になったと記載があったので、typeの記載はなくて良し

セクレタ
タイプセクレタ(=要素セクレタ)
h1、h2、p、ul、img...
例：divクラスにクラス名"color"を追加
... <style> .color { color: red; } </style> <body> <div>おはよう</div> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script> <script src="script.js"></script> </body> ...
script.js
$("div").addClass("color");
クラスセクレタ
.a、.b、.cのようにドットの後ろに任意(好きな)の文字を記述
例：aクラスのフォントの色をピンクに変更
... <body> <div class="a">おはよう</div> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script> <script src="script.js"></script> </body> ...
$(".a").css("color", "pink");
IDセレクタ
#abc、#xyz、#nameのようにドットの後ろに任意(好きな)の文字を記述
例：divにid属性appを追加し、#app(idセクレタ)の色を赤に変更する
<body> <div>おはよう</div> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script> <script src="script.js"></script> </body>
$("div").attr("id", "app");
$("#app").css("color", "red");
グループセクレタ
複数のセレクタをカンマ区切りで同時に指定する
例：div、liのフォントをピンクに変える
<body> <div>おはよう</div> <li>こんばんは</li> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script> <script src="script.js"></script> </body>
$("div, li").css("color", "pink");
スペース区切り
複数のセレクタをスペースで区切り、任意タグの中のタグ(子や孫)にのみ適用
例：divタグ内のliタグの色だけピンクに変える
<body> <div> <div>ああああ</div> <li>おおおお</li> </div> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script> <script src="script.js"></script> </body>
