***已解决 哎呀！我忘记将 plan_id 迁移到 users 表...

在 Michael Hartl 的教程之后，我一直在窃听自己的应用程序。现在，有两个表——计划和用户。计划 has_many users 和 users belongs_to Plans，现在我要做的是完成注册过程，所以当有人通过 plan_id=? 进入注册表单时，它会将其提交到隐藏的表单字段，并且注册用户。

但是，当我尝试访问我的 signup_path 时，我收到此错误：

ActiveRecord::UnknownAttributeError in UsersController#new

unknown attribute: plan_id

我不太确定该怎么做。会喜欢你的想法！

用户控制器

class UsersController < ApplicationController

  before_filter :signed_in_user, only: [:show]
  before_filter :correct_user,   only: [:show]

    def show
    @user = User.find(params[:id])
    end

    def new
  plan = Plan.find(params[:plan_id])
    @user = plan.users.build
    end

  def create
    @user = User.new(params[:user])
    if @user.save
      sign_in @user
      flash[:success] = "Welcome to the Sample App!"
      redirect_to @user
    else
      render 'new'
    end
  end

  def index

    if current_user
      redirect_to(user_path(current_user))
    else
    redirect_to(root_path)
    end
  end

  private

    def signed_in_user
      unless signed_in?
        store_location
        redirect_to login_url, notice: "Please sign in."
      end
    end

    def correct_user
      @user = User.find(params[:id])
      redirect_to(root_path) unless current_user?(@user)
    end
end

查看/用户/new.html.erb

<% provide(:title, 'Sign up') %>
<div class="contentstripe">
<div class="container">
  <div class="row">
   <h1>Sign Up </h1>
  </div>
</div>
</div>

<div class="container">

      <%= f.hidden_field :plan_id %>

      <%= f.label :name %>
      <%= f.text_field :name %>

      <%= f.label :email %>
      <%= f.text_field :email %>

      <%= f.label :password %>
      <%= f.password_field :password %>

      <%= f.label :password_confirmation, "Confirmation" %>
      <%= f.password_field :password_confirmation %>

      <%= f.submit "Create my account", class: "btn btn-large btn-primary" %>

您的方法的 urlUsersController#new必须包含一个plan_id部分，后跟一个id应该由params[:plan_id]. 你的网址是这样的吗？你可以添加你的输出的相关部分rake routes。
