我有 "ActiveModel::ForbiddenAttributesError in UsersController#create"

Question

请尝试 运行 这段代码，但我在 UsersController#create 中确实有 ActiveModel::ForbiddenAttributesError 错误，请问我该如何修复它

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 solution.You 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
