[英]Ruby on Rails -- ActiveModel::ForbiddenAttributesError
[英]ActiveModel::ForbiddenAttributesError Ruby On Rails
我在Ruby On rails中創建了一個項目,並且有這樣的控制器用戶:
class UsersController < ApplicationController
before_action :set_user, only: [:edit, :update]
def new
@user = User.new
end
def create
@user = User.new(params[:user])
if @user.save
redirect_to root_url, :notice => "Signed up!"
else
render "new"
end
end
private
def user_params
params.require(:user).permit(:email, :password, :password_confirmation)
end
end
和模型用戶是這樣的:
class User < ActiveRecord::Base
#attr_accessible :email, :password, :password_confirmation
attr_accessor :password
before_save :encrypt_password
def self.authenticate(email, password)
user = find_by_email(email)
if user && user.password_hash == BCrypt::Engine.hash_secret(password, user.password_salt)
user
else
nil
end
end
def encrypt_password
if password.present?
self.password_salt = BCrypt::Engine.generate_salt
self.password_hash = BCrypt::Engine.hash_secret(password, password_salt)
end
end
end
當我嘗試創建新用戶時,出現錯誤:ActiveModel :: ForbiddenAttributesError
參數:
{"utf8"=>"✓",
"authenticity_token"=>"74Mhbpn9FF/tY/cgfuVmX7ribN4rOkkdUjSgbLNsces=",
"user"=>{"email"=>"henio180@interia.pl",
"password"=>"[FILTERED]",
"password_confirmation"=>"[FILTERED]"},
"button"=>""}
我正在使用Ruby on Rails 4.0.3。
在您的create
方法更改中:
@user = User.new(params[:user])
至
@user = User.new(user_params)
盡管您正確地創建了用於設置強參數的方法,但實際上並沒有使用它。 在Rails指南中有關於使用強參數的詳細信息: http : //guides.rubyonrails.org/action_controller_overview.html#strong-parameters
