如何使用 wicked 进行验证? [英] how validation is done using wicked?

问题描述

我有一个 users_controller 和一个 user_steps_controller，它们有三个步骤:业务、:付款和:登录

I have a users_controller and a user_steps_controller which has three steps :business, :payment and :login

在 user.rb 模型中

In the user.rb model

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

在检查验证时，如果我输入了一些随机值，它也会给出错误

while checking validation if i put some random values then also it is giving errors

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

This is my 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

用户.rb

类用户

class 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

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

推荐答案

你真正的问题在这里:

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

我假设 params[:id] 是 nil，否则会失败.基本上，您在不提供数据的情况下实例化 User 并尝试保存它.很明显，您提供的那些验证将失败.如果您实际提交包含用户数据的表单，则需要传递您已经定义如下的 user_params:

I'm assuming params[:id] is nil, because otherwise that would fail. Basically, your instantiating a User with no data supplied and trying to save it. So clearly those validations you have supplied will fail. If you're actually submitting a form with user data you need to pass user_params you've already defined as follows:

@user = User.new(user_params)

@user = User.new(user_params)

如果您需要在不同步骤中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:

If you need to have validations occur on your User model in different steps, you'll need to have the validations run conditionally dependent on the state of the form:

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
