以前にこれに似た質問を投稿しましたが、 FriendlyIds gem を使用するよう提案されましたが、いくつかの実際の問題があったため、私には適していませんでした。どんどん進んでいく…

whatsaw.com/first_name-second_name を指す URL を作成しようとしていますが、それは機能していますが、人々が同じ名前でサインアップした場合は考慮されません。

私はこのコードをオンラインで見つけましたが、私にはかなり健全に思えます - 私の generate_slug メソッドは私の user_controller 内にありますが、アプリに再度サインアップしようとするとエラーが発生します。

UsersController の NoMethodError#未定義のメソッド「user」を作成 #

これが generate_slug メソッドです。

  def generate_slug
  if user(:slug => full_name.parameterize).count > 0
    n = 1
    while user(:slug => "#{full_name.parameterize}-#{n}").count > 0
      n += 1
    end
    self.slug= "#{full_name.parameterize}-#{n}"
  else
    self.slug = full_name.parameterize
  end
end

そしてこちらが users#create; です。

  def create 
    user = User.find_by_email(params[:sessions][:email])
    if user && user.authenticate(params[:sessions][:password])
      if params[:remember_me]
        cookies.permanent[:auth_token] = user.auth_token
      else
        cookies[:auth_token] = user.auth_token
      end
      redirect_to users_show_path(current_user), notice: "Logged in"
    else
      flash.now.alert = "Email or password is invalid."
      render "new"
    end
  end

誰がこれの何が悪いのか分かりますか? 私はさまざまなことを試してハッキングしましたが、レールに非常に慣れていないため、ここで何が間違っているのかわかりません。

どんな助けや指針も大歓迎です、

御時間ありがとうございます！

2 -ユーザー モデルの before_create で generate_slug が作成されている

3-私もそれでいくつかの問題を抱えていました-それは非常に気分が悪いようです-あなたが言ったように、私はユーザーに変更しようとしましたが、うまくいきませんでした-しかし、current_userはもう機能しません-私はそれを調べますちょうど今

4 -いいえ、私は認証ジェムを使用していません。これを使用して、いくつかのレールとその背後にある理論を学んでいるだけなので、ジェムを避けようとしています :)

もう少し背景が必要です。

  1. エラーは不完全です。完全なトレースを提供してください。
  2. どこgenerate_slugから呼ばれる？before_createモデルのユーザーですか？
  3. メソッドで呼び出しcurrent_userていredirect_toますcreate。user以前に定義した変数ではないのはなぜですか?
  4. Devise や Clearance などの認証ジェムを使用していますか?

user_idスラッグに追加するのは簡単ではありませんか？

def generate_slug
  "#{id}-#{full_name.parameterize}"
end
