wrong number of arguments (given 2, expected 0..1)
モデルのビューを追跡しようとすると、エラーが発生します。
私のモデル:
class Codetip < ApplicationRecord
belongs_to :user
is_impressionable
validates :title, presence: true, length: { minimum: 4 }
validates :body, presence: true, length: { minimum: 4 }
validates :user_id, presence: true
extend FriendlyId
friendly_id :name, use: :slugged
end
コードチップ コントローラー:
https://github.com/charlotte-ruby/impressionistが使用法の下のセクション 4 で提案したように。
def show
@codetip = Codetip.friendly.find(params[:id])
impressionist(@codetip)
end
私のショービュー:
<%= @codetip.impressionist_count %>
次に、ウィキが提案したすべてのことを行いました。gem の追加、バンドル、インプレッション テーブルの生成、および移行です。
