投稿記事にタグを入れたseedデータの作り方

困っていたこと

記事モデルに対して、別テーブルにあるタグ情報と会員情報の結び付けをし、seedファイルへといれるにはどのようにしたらいいか迷っていた。

解決方法

下記のように記述したら、seedデータにmember情報とtag情報をarticleへいれることが出来た。

db/seed.rb

# メンバーサンプル
# admin = true
sugi = Member.find_or_create_by!(email: "sugi@sugi") do |member|
  member.name = "sugi"
  member.introduction = "よろしくお願いします！"
  member.password = "123456789"
  member.password_confirmation = "123456789"
  member.admin = true
  member.profile_image = ActiveStorage::Blob.create_and_upload!(io: File.open("#{Rails.root}/app/assets/images/user_1.jpg"), filename:"user_1.jpg")
end

# admin = false
alice = Member.find_or_create_by!(email: "alice@alice") do |member|
  member.name = "alice"
  member.introduction = "よろしくお願いします！"
  member.password = "password1"
  member.password_confirmation = "password1"
  member.admin = false
  member.profile_image = ActiveStorage::Blob.create_and_upload!(io: File.open("#{Rails.root}/app/assets/images/user_2.jpg"), filename:"user_2.jpg")
end

# 記事サンプル
article1 = Article.find_or_create_by!(title: "のあです") do |article|
  article.text = "Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aenean commodo ligula eget dolor. Aenean massa. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Donec quam felis, ultricies nec, pellentesque eu, pretium quis, sem. Nulla consequat massa quis enim. Donec pede justo, fringilla vel, aliquet nec, vulputate eget, arcu. In enim justo, rhoncus ut, imperdiet a, venenatis vitae, justo. Nullam dictum felis eu pede mollis pretium. Integer tincidunt. Cras dapibus. "
  article.member = sugi
  article.article_image = ActiveStorage::Blob.create_and_upload!(io: File.open("#{Rails.root}/app/assets/images/article_1.jpg"), filename:"article_1.jpg")
end

article2 = Article.find_or_create_by!(title: "ドッグランで遊んだよ") do |article|
  article.text = "Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aenean commodo ligula eget dolor. Aenean massa. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Donec quam felis, ultricies nec, pellentesque eu, pretium quis, sem. Nulla consequat massa quis enim. Donec pede justo, fringilla vel, aliquet nec, vulputate eget, arcu. In enim justo, rhoncus ut, imperdiet a, venenatis vitae, justo. Nullam dictum felis eu pede mollis pretium. Integer tincidunt.

  article.member = alice
  article.article_image = ActiveStorage::Blob.create_and_upload!(io: File.open("#{Rails.root}/app/assets/images/article_2.jpg"), filename:"article_2.jpg")
end

# タグサンプル
tag1 = Tag.create(tag_name:"トイプードル")
tag2 = Tag.create(tag_name:"散歩")
tag3 = Tag.create(tag_name:"ゴールデンレトリバー")
tag4 = Tag.create(tag_name:"ドッグラン")

article1.tags << tag1
article1.tags << tag2
article2.tags << tag3
article2.tags << tag4
