Question

这个ruby类引发了一个错误用户是表的名称，所以我不知道为什么它说索引方法中的错误是因为Users.all必须返回零 C：/ProyectosRails/gag_cf/app/models/user.rb：4：语法错误，意外＆＃39; \ n＆＃39;，期待tASSOC

提取的来源（第7行）：

# GET /users.json
def index
@users = User.all
end

这是控制器

class UsersController < ApplicationController
  before_action :set_user, only: [:show, :edit, :update, :destroy]

  def index
    @users = User.all
  end


  def show
  end


  def new
    @user = User.new
  end


  def edit
  end


  def create
    @user = User.new(user_params)

    respond_to do |format|
      if @user.save
        format.html { redirect_to @user, notice: 'User was successfully created.' }
        format.json { render action: 'show', status: :created, location: @user }
      else
        format.html { render action: 'new' }
        format.json { render json: @user.errors, status: :unprocessable_entity }
      end
    end
  end


  def update
    respond_to do |format|
      if @user.update(user_params)
        format.html { redirect_to @user, notice: 'User was successfully updated.' }
        format.json { head :no_content }
      else
        format.html { render action: 'edit' }
        format.json { render json: @user.errors, status: :unprocessable_entity }
      end
    end
  end


  def destroy
    @user.destroy
    respond_to do |format|
      format.html { redirect_to users_url }
      format.json { head :no_content }
    end
  end

    class User < ActiveRecord::Base
        authenticates_with_sorcery!
          validates_confirmation_of :password, message: "Both fields must match", if :password
     end

你有一个额外的逗号（,）。删除此额外,。以下代码取自OP的comment。

class User < ActiveRecord::Base 
  authenticates_with_sorcery! 
  validates_confirmation_of :password, message: "Both fields must match", if :password
                                                                   # see|
end

我在控制器中缺少什么？
