让 Stripe 在 Rails 4 中工作

Question

我正在尝试在 rails 中设置条带，我可以输入信用卡信息，但是当它重定向时我收到以下错误：

No route matches [POST] "/enrollment/1"

我很困惑，因为当我收集路线时，我得到：

 enrollment_index GET    /enrollment(.:format)                                 enrollment#index
                  POST   /enrollment(.:format)                                 enrollment#create
   new_enrollment GET    /enrollment/new(.:format)                             enrollment#new
  edit_enrollment GET    /enrollment/:id/edit(.:format)                        enrollment#edit
       enrollment GET    /enrollment/:id(.:format)                             enrollment#show
                  PATCH  /enrollment/:id(.:format)                             enrollment#update
                  PUT    /enrollment/:id(.:format)                             enrollment#update
                  DELETE /enrollment/:id(.:format)                             enrollment#destroy

所以我很困惑为什么要尝试 post 因为在我看来，我指定应该放置该方法：

 <div class='container'>
        <div class='jumbotron enroll-page'>
            <div class='row'>
                <h1>Enroll Here</h1>
                <%= form_tag enrollment_path(1), :method => :put do %>
                  <article>
                    <label class="amount">
                      <span>Amount: .00</span>
                    </label>
                  </article>

                  <script src="https://checkout.stripe.com/checkout.js" class="stripe-button"
                          data-key="<%= Rails.configuration.stripe[:publishable_key] %>"
                          data-description="A month's subscription"
                          data-amount="500"></script>
                <% end %>

            </div>
        </div>
    </div>

我的控制器是这样的：

class EnrollmentController < ApplicationController
    before_filter :authenticate_user!, unless: :admin_signed_in?

    def new
    end

    def create
        #get credit card details submitted by form
        token = params[:stripeToken]

        customer = Stripe::Customer.create(
            :card => token,
            :plan => 3455,
            :email => current_user.email
        )

        current_user.paid = true
        current_user.stripeid = customer.id
        current_user.save

        redirect_to courses_path, :notice => 'Your enrollment is complete!'
    end
end

非常感谢您提供的任何帮助！

编辑：我想我知道了。 Ajay 完全正确，如果我将控制器命名为 "enrollments" 而不是注册，效果会更好。在 new.html.erb 视图中，它应该看起来像这样：

<div class='container'>
    <div class='jumbotron enroll-page'>
        <div class='row'>
            <h1>Enroll Here</h1>
            <%= form_tag enrollments_path do %>
              <article>
                <label class="amount">
                  <span>Amount: .00</span>
                </label>
              </article>

              <script src="https://checkout.stripe.com/checkout.js" class="stripe-button"
                      data-key="<%= Rails.configuration.stripe[:publishable_key] %>"
                      data-description="A month's subscription"
                      data-amount="500"></script>
            <% end %>

        </div>
    </div>
</div>

Answer 1

签入路线资源必须是注册而不是注册

 #routes.rb
resources :enrollments

现在当你运行

rake routes | grep 'enrollment'
new_enrollment  GET   /enrollments/new(.:format)  enrollments#new

#app/controller/enrollments_controller.rb

class EnrollmentsController < ApplicationController
  def new 
   @enrollment = Enrollment.new 
  end

  def edit
    @enrollment = Enrollment.where(id: params[:id]).first 
  end

  def create 
    #catch your params and do whatever. 
  end

  def update
    # catch your params and do your operation.
   end
end

视图来了：

app/views/enrollments/new.html.erb 
 <%= render 'form %> 
app/views/enrollments/edit.html.erb
<%= render 'form' %>

现在在你的 app/views/enrollments/_form.html.erb

 <%= form_tag(@enrollment)do %>

   <%= label_tag :amount %> 
   <%= text_field_tag :amount, 50.00 %> 

   <%= submit_tag %> 
 <% end %>

在您的控制台中，日志应该是这样的：

Started GET "/enrollments/new" for 127.0.0.1 at 2015-01-10 06:18:08 +0530
Processing by EnrollmentsController#new as HTML

这确认您正在访问新页面而不是编辑页面。核实！

检查你的表格，它应该是这样的，检查一下。
