FBメッセの相手のアイコンと名前を隠すChrome拡張をリリース🎉
Rspecでテストをスキップさせる
（あまり良くないんだけど）ちょっとスキップしたい場面に出くわしたのでメモ
ブロックを skip とするか
RSpec.describe "an example" do skip "is skipped" do end end
頭に x をつければいいだけらしい🙄
RSpec.describe "an example" do xit "is skipped using xit" do end xspecify "is skipped using xspecify" do end xexample "is skipped using xexample" do end end

RailsでCloudinaryを使う
CarrierWave、Cloudinaryを使った画像アップロードの方法です。
今回のバージョン
ruby: 2.5.0 rails: 5.1.6
Cloudinaryに登録
Cloudinaryに登録して使える状態にしておきます。
登録後サイト内で cloudinary.yml がダウンロードできるはずなのでしておきましょう。
Gem追加
Gemfileに下記を追加
gem 'carrierwave' gem 'cloudinary'
bundle install
Uploader作成
rails g uploader Image
Cloudinaryを使うよう修正
storage :file
を以下に変更
if Rails.env.production? include Cloudinary::CarrierWave else # 本番以外ではローカルに保存する storage :file end
ファイルアップロードしたいモデルにマウント
例Userモデル
class User < ApplicationRecord mount_uploader :image, ImageUploader end
cloudinary.yml追加
最初にダウンロードしたcloudinary.ymlを
config/cloudinary.yml に配置
フォーム修正
fileのinputとサムネイルを表示
_form.html.erb
<%= image_tag(@user.image_url(:thumbnail), :width => 80, :height => 80) %> <%= f.file_field :image %>
webpackerでA JSON text must at least contain two octets! (JSON::ParserError)と怒られた話
エラー内容
rails c や rails s をすると以下のエラーが
webpack系のjsonのパースが上手くいっていないよっていうエラーっぽい
