Rails: 密码不能为空 has_secure_password
Rails: Password can't be blank with has_secure_password
我正在尝试按照本教程 (Rails Tutorial by Michael Hartl) 创建一个有效用户。填写密码字段仍然给我错误 "Password cannot be blank" 和 "Password has to be longer thank 6 letters"。我尝试通过 rails 控制台创建用户，效果很好。仅当我尝试通过网站本身进行操作时。
我的用户模型是这样的：
class User < ApplicationRecord
#before saving, make sure the email is in downcase
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, length: { maximum: 255 },
format: { with: VALID_EMAIL_REGEX },
uniqueness: {case_sensitive: false}
has_secure_password
validates :password, presence: true, length: { minimum: 6 }
end
我的 user_controller 看起来像这样：
class UsersController < ApplicationController
before_action :set_user, only: [:show, :edit, :update, :destroy]
#wrap_parameters :user, include: [:name, :email, :password, :password_confirmation]
def index
@users = User.all
end
def show
@user = User.find(params[:id])
#debugger
end
def new
@user = User.new
end
# GET /users/1/edit
def edit
end
#POST /users
#POST /users.json
def create
@user = User.new(user_params) #params[:user])#user_params)
respond_to do |format|
if @user.save
#flash[:success] = "Welcome to CourseBuddies!"
format.html { redirect_to @user, notice: 'User was successfully created.' }
format.json { render :show, status: :created, location: @user }
redirect_to @user
else
#render 'new'
format.html { render :new }
format.json { render json: @user.errors, status: :unprocessable_entity }
end
end
end
# PATCH/PUT /users/1
# PATCH/PUT /users/1.json
def update
respond_to do |format|
if @user.update(user_params)
format.html { redirect_to @user, notice: 'User was successfully updated.' }
format.json { render :show, status: :ok, location: @user }
else
format.html { render :edit }
format.json { render json: @user.errors, status: :unprocessable_entity }
end
end
end
# DELETE /users/1
# DELETE /users/1.json
def destroy
@user.destroy
respond_to do |format|
format.html { redirect_to users_url, notice: 'User was successfully destroyed.' }
format.json { head :no_content }
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_user
@user = User.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def user_params
params.require(:user).permit(:name, :email, :pasword, :password_confirmation)
end
end
这是我的迁移文件create_user：
class CreateUsers < ActiveRecord::Migration[5.0]
def change
create_table :users do |t|
t.string :name
t.string :email
t.string :password
t.string :password_confirmation
t.timestamps
end
end

我试过在网上找到的不同解决方案，比如使用 "wrap_parameters"，但它似乎对我没有任何作用。

如有任何帮助或说明，我将不胜感激。谢谢！
我认为您需要在验证中添加 allow_nil: true
validates :password, presence: true, length: { minimum: 6 }, allow_nil: true
As allow_nil: true 将不允许创建空字符串。
错误的真正原因是您在 user_params 中 将 password 误输入为 pasword。修正拼写错误应该可以解决您的问题。
def user_params
params.require(:user).permit(:name, :email, :password, :password_confirmation)
end
解决方案：
Okey，所以在我的控制器中修复了我的拼写错误（@Pavan 指出）之后，我还删除了我的用户模型（@Divya Sharma）中的 presence:true，所以它看起来像这样:
validates :password, length: { minimum: 6 }, allow_nil: true
我现在可以正确注册我的用户并登录了！
我认为输入 "allow_nil:true" 实际上只是让我注册了，因为不知何故，我的 password_fields 仍然是 "nil"。我想那是因为我的打字错误。无论如何，感谢你们这么快！
