このチュートリアル ( Rails Tutorial by Michael Hartl )に従って有効なユーザーを作成しようとしています。パスワードフィールドに入力しても、「パスワードを空白にすることはできません」および「パスワードは6文字以上にする必要があります」というエラーが表示されます。Railsコンソールからユーザーを作成しようとしましたが、うまくいきました。それは私がウェブサイト自体を通してそれをやろうとしたときだけです.

私のユーザーモデルは次のようになります。

class User < ApplicationRecord
  #before saving, make sure the email is in downcase
  before_save { self.email = email.downcase }

  validates :name,  presence: true, length: { maximum: 50 }
  VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
  validates :email, presence: true, length: { maximum: 255 },
                format: { with: VALID_EMAIL_REGEX },
                uniqueness: {case_sensitive: false}

  has_secure_password
  validates :password, presence: true, length: { minimum: 6 }
end

私の user_controller は次のようになります。

class UsersController < ApplicationController
before_action :set_user, only: [:show, :edit, :update, :destroy]
#wrap_parameters :user, include: [:name, :email, :password, :password_confirmation]

def index
  @users = User.all
end

def show
  @user = User.find(params[:id])
  #debugger
end
def new
  @user = User.new
end

# GET /users/1/edit
def edit
end

#POST /users
#POST /users.json
def create
  @user = User.new(user_params) #params[:user])#user_params)

  respond_to do |format|
    if @user.save
      #flash[:success] = "Welcome to CourseBuddies!"

      format.html { redirect_to @user, notice: 'User was successfully created.' }
      format.json { render :show, status: :created, location: @user }
      redirect_to @user
    else
      #render 'new'
      format.html { render :new }
      format.json { render json: @user.errors, status: :unprocessable_entity }
    end
  end
end

# PATCH/PUT /users/1
# PATCH/PUT /users/1.json
def update
  respond_to do |format|
    if @user.update(user_params)
      format.html { redirect_to @user, notice: 'User was successfully updated.' }
      format.json { render :show, status: :ok, location: @user }
    else
      format.html { render :edit }
      format.json { render json: @user.errors, status: :unprocessable_entity }
    end
  end
end

# DELETE /users/1
# DELETE /users/1.json
def destroy
  @user.destroy
  respond_to do |format|
    format.html { redirect_to users_url, notice: 'User was successfully destroyed.' }
    format.json { head :no_content }
  end
end

private
  # Use callbacks to share common setup or constraints between actions.
  def set_user
    @user = User.find(params[:id])
  end

  # Never trust parameters from the scary internet, only allow the white list through.
  def user_params
    params.require(:user).permit(:name, :email, :pasword, :password_confirmation)
  end
end

これは私の移行ファイル create_user です:

class CreateUsers < ActiveRecord::Migration[5.0]
 def change
   create_table :users do |t|
     t.string :name
     t.string :email
     t.string :password
     t.string :password_confirmation

     t.timestamps
   end
 end

終わり

「wrap_parameters」を使用するなど、オンラインで見つかったさまざまなソリューションを試しましたが、何もしないようです。

検証に allow_nil: true を追加する必要があると思います

validates :password, presence: true, length: { minimum: 6 }, allow_nil: true

allow_nil: true として、空の文字列の作成を許可しません。
