Question

我正在尝试使用Ruby on Rails处理一个简单的注册页面，但是我遇到了一个问题。当用户登录时，我设置的验证错误将在不应该被触发时触发（它说密码不够长）。

以下是一些相关代码：

user_controller.rb：

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 :show, status: :created, location: @user }
      else
        format.html { render :new }
        format.json { render json: @user.errors, status: :unprocessable_entity }
      end
    end
  end

User.rb型号：

class User < ActiveRecord::Base
    #attr_accessor :name, :email, :password_digest
    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,
                      format: { with: VALID_EMAIL_REGEX }, 
                      uniqueness: { case_sensitive: false }

    has_secure_password
    validates :password, length: { minimum: 6 }

    has_many :microposts
end

new.html.slim视图：

- provide(:title, 'Sign up')
h1 Sign up
.row
  .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.text_field :email, class: 'form-control'
      = f.label :password
      = f.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"

当我尝试创建新用户时，路由会从注册更改为用户。但是，未创建用户，错误包括：

表单包含2个错误。密码不能为空密码太短（最少6个字符）

但是，输入了密码。你看到任何会导致这种情况的东西吗？谢谢。

编辑：

尝试在注册页面上创建用户时，这是控制台输出：

我不确定为什么密码和password_confirmation是“不准备”的。有任何想法吗？

Answer 1

打印出你传递给User.new（）的内容。如果未传入密码，请检查是否已在强参数中明确允许密码。 ie）params.require（：user）.permit（：name，：email，：password）

Answer 2

确保您使用的是Devise最新版本，并查看DeviseStrongParameters

添加到您的应用程序控制器

before_filter :add_sanitized_params, if: :devise_controller?

def add_sanitized_params
  devise_parameter_sanitizer.for(:sign_up) {|u| u.permit(:password, :password_confirmation)}
end

如果不起作用，请告诉我......
