在UsersController中创建＆＃34; ActiveModel :: ForbiddenAttributesError #create＆＃34;

Question

请我尝试运行此代码，但我确实在UsersController中创建了ActiveModel :: ForbiddenAttributesError #create error，我该如何解决呢

class UsersController < ApplicationController

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

  def agent_signup
    @user = User.new
  end

  def create
    @user = User.new(params[:user])    # Not the final implementation!
    if @user.save
      # Handle a successful save.
    else
      render 'agent_signup'
    end
  end

   private

    def user_params
      params.require(:user).permit(:name, :email, #:password,
                                   #:password_confirmation
                                    )
    end
end

Answer 1

应该是

# Wrong
@user = User.new(params[:user])    # Not the final implementation!
# Correct
@user = User.new(user_params)    # Not the final implementation!

为了使用允许的参数

Answer 2

试试这个解决方案。你需要允许参数。

def create
  @user = User.new(user_params)
   if @user.save
     # Handle a successful save.
   else
    render 'agent_signup'
   end
end
