【问题描述】：

我是一名 RoR 新手，正在尝试将 Stripe 与 Devise 集成，以便我可以注册我的应用的新订阅者，并将他们设置为按月收费。我已关注 Railscast (http://railscasts.com/episodes/288-billing-with-stripe) 并查看了此处的 QA (Using Stripe with Devise for Ruby on Rails Subscriptions)，但仍然无法使其正常工作/完全理解我做错了什么。本质上，我希望（如果可能）使用我的设计用户模型和注册控制器，而不必创建/使用订阅模型/控制器。

我将 Railscast 中的代码放在适当的位置，但仍然收到错误，例如：

NoMethodError in Users/registrations#create

Showing /app/views/users/registrations/new.html.erb where line #7 raised:

undefined method `errors' for nil:NilClass

Extracted source (around line #7):

4: <h2>Sign up</h2>
5: 
6: <%= form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f| %>
7:   <%= devise_error_messages! %>
8: 
9:   <div><%= f.label :email %><br />
10:   <%= f.email_field :email %></div>

非常感谢任何帮助/指导。

【问题讨论】：

你有没有想过这个问题？我遇到了同样的问题。

不，我最终使用了 SaaS RailsKit，它现在包含 Stripe 并拥有 Devise。

以下解决方案应该可以为您节省一些现金；）

【参考方案1】：

根据您命名模型（用户）的方式，您应该更改@subscription -> @user。

像这样--

controllers/registrations_controller.rb

def create

  @user = User.new(params[:user])
  if @user.save_with_payment
    redirect_to @user, :notice => "Thank you for subscribing!"
  else
    render :new
  end
