我在 Ruby 中有这个模型,但它抛出了一个ActiveModel::ForbiddenAttributesError
class User < ActiveRecord::Base
attr_accessor :password
validates :username, :presence => true, :uniqueness => true, :length => {:in => 3..20}
VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
validates :email, presence: true, :uniqueness => true, format: { with: VALID_EMAIL_REGEX }
validates :password, :confirmation => true
validates_length_of :password, :in => 6..20, :on => :create
before_save :encrypt_password
after_save :clear_password
def encrypt_password
if password.present?
self.salt = BCrypt::Engine.generate_salt
self.encrypted_password= BCrypt::Engine.hash_secret(password, salt)
end
end
def clear_password
self.password = nil
end
end
当我运行这个动作时
def create
@user = User.new(params[:user])
if @user.save
flash[:notice] = "You Signed up successfully"
flash[:color]= "valid"
else
flash[:notice] = "Form is invalid"
flash[:color]= "invalid"
end
render "new"
end
on ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux]
.
您能告诉我如何消除此错误或建立正确的用户注册表单吗?
我猜你使用的是Rails 4。如果是这样,则需要的参数必须按要求标记。
你可能想这样做:
class UsersController < ApplicationController
def create
@user = User.new(user_params)
# ...
end
private
def user_params
params.require(:user).permit(:username, :email, :password, :salt, :encrypted_password)
end
end
