红宝石form_for密码字段未提交给params散列表

Question

现在通过Hartl的rails教程工作。

密码字段显示不正常，并且当我提交一些信息时，我可以看到我的参数哈希不显示密码密钥（但显示其他所有内容）。这是怎么回事？

视图/用户/ new.html.erb：

<h1> Sign up </h1> 
<div class = "row"> 
    <div class = "col-md-6 col-md-offset-3"> 
     <%= form_for(@user) do |f| %> 
     <%= render 'shared/error_messages' %> 

     <%= f.label :name %> 
     <%= f.text_field :name, class: 'form-control'%> 


     <%= f.label :email %> 
     <%= f.email_field :email, class: 'form-control'%> 

     <%= f.label :password %> 
     <%= password_field :password, class: 'form-control'%> 

     <%= f.label :password_confirmation, "Confirmation" %> 
     <%= f.password_field :password_confirmation, class: 'form-control'%> 

     <%= f.submit "Create my account", class: "btn btn-primary" %> 
     <% end %> 
    </div> 
</div> 

控制器/ users_controller.rb

class UsersController < ApplicationController 
    before_action :logged_in_user, only: [:edit, :update] 
    before_action :correct_user, only: [:edit, :update] 
    def new 
    @user = User.new 
    end 

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

    def create 
    @user = User.new(user_params) 
    if @user.save 
     @user.send_activation_email 
     flash[:info] = "Please check your email to activate your account." 
     redirect_to root_url 
    else 
     render 'new' 
    end 
    end 

def edit 
@user = User.find(params[:id]) 
end 

def update 
@user = User.find(params[:id]) 
if @user.update_attributes(user_params) 
flash[:success] = "Profile updated" 
redirect_to @user 
else

end 
end 

    private

    params.require(:user).permit(:name, :email, :password, :password_confirmation)

flash[:danger] = "Please log in." 
redirect_to login_url 
end 
end 

def correct_user 
@user = User.find(params[:id]) 
redirect_to(root_url) unless current_user?(@user) 
end 

end
