如何使用邪恶完成验证？

我有一个users_controller和一个user_steps_controller，它具有三个步骤：业务，：付款和：login

在user.rb模型中

class User < ActiveRecord::Base
validates_presence_of :fname, :lname, :email, :mob, :country, :state, :suburb, :postal ,:add
end

在检查验证时是否放了一些随机值，这也给了错误

Fname can't be blank
Lname can't be blank
Email can't be blank
Mob can't be blank
Country can't be blank
State can't be blank
Suburb can't be blank
Postal can't be blank
Add can't be blank

请帮帮我

这是我的users_controller

  def new
    @user = User.new
  end

  def create
    @user = User.new(params[:id])
    if @user.save
      session[:user_id]= @user.id
      @user.update_attributes(user_params )
      redirect_to user_steps_path
    else
      render :new
    end
  end

  private
  def user_params
    params.require(:user).permit( :fname, :lname, :email, :mob, :gender_male, :gender_female, :country, :state, :suburb, :postal ,:add, :cmpyname, :abnacn, :cmpyadd, :cmpydet,:cash, :paypal,:bsb,:usrname,:password_hash, :password_salt, :selcat, :protit, :prodes)
  end

user.rb

类User <ActiveRecord :: Base

validates :fname, :lname, :email, :mob, :country, :state, :suburb, :postal ,:add, :presence => true

attr_accessor :current_step

validates_presence_of :cmpyname, :abnacn, :cmpyadd, :cmpydet, if: -> { current_step?(:business) }
validates_presence_of :usrname,:password_hash, :password_salt, :selcat, :protit, :prodes, if: -> { current_step?(:login) }

def current_step?(step_key)
  current_step == step_key
end

end

user_steps_controller

class UserStepsController < ApplicationController
  include Wicked::Wizard
  steps :business, :login, :payment

def show
  @user = current_user
  render_wizard
end

  def update

    @user = current_user
    params[:user][:current_step] = step
    @user.update_attributes(user_params )
    render_wizard @user

  end

 private
  def user_params
    params.require(:user).permit( :cmpyname, :abnacn, :cmpyadd, :cmpydet,:cash, :paypal,:bsb,:usrname,:password_hash, :password_salt, :selcat, :protit, :prodes)
  end
end

您的真正问题在这里：

@user = User.new(params[:id])

我假设params[:id]是nil，因为否则将失败。基本上，您实例化一个User没有提供数据的a并尝试保存它。显然，您提供的那些验证将失败。如果您实际上是在提交包含用户数据的表单，则需要通过user_params以下定义：

@user = User.new（user_params）

如果需要以不同的步骤对用户模型进行验证，则需要根据表单的状态有条件地运行验证：

class User 
  attr_accessor :current_step
  validates_presence_of :business_related_attr, if: -> { current_step?(:business) }

  def current_step?(step_key)

    current_step.blank? || current_step == step_key
  end
end
