Question

我正在尝试使用Stripe处理信用卡付款，但我正在努力解决基本的铁轨问题，我是新手。我不能让控制器使用方法“save_with_payment”，它跳过并重定向错误通知。表单在事件显示页面上，我有一个注册模型来处理付款。对于不正确的缩进道歉我仍然对此持怀疑态度。另一个错误是重定向转到事件索引页面而不是显示页面。很困惑。

模型

class Registration
  include Mongoid::Document

  field :address 
  field :email
  field :job_title
  field :company
  field :first_name
  field :last_name
  field :postcode
  field :stripe_card_token
  field :stripe_customer_token

  def save_with_payment
    if valid?
    charge = Stripe::Charge.create({
     amount: 40000,
     currency: "gbp",
     card: stripe_card_token,
     description: email
    })
    save
   end
    rescue Stripe::CardError => e
  end

end

控制器

class EventsController < ApplicationController
  def index
    @event = Event.all
  end 

  def show
     @event = Event.where(:slug => params[:slug]).first
     @registration = Registration.new
  end

  def payment
    @registration = Registration.new(params[:registration])
     if @registration.save_with_payment(@event)
      redirect_to events_path(@event), :notice => "Thank you for registering for"
     else
      redirect_to events_path(@event), :notice => "We're sorry, something went wrong"
     end
  end
end

路线

match 'registration' => 'events#show', :via => :get
match 'registration' => 'events#payment', :via => :post
match '/:slug' => "events#show"

视图

<%= simple_form_for [@registration], :method => :post, :url => registration_path do |f| %>
<%= f.input :first_name %>
<%= f.input :last_name %>
<%= f.input :email %>
<%= f.input :job_title %>
<%= f.input :company %>
<%= f.input :stripe_card_token, as: :hidden %>
<div class="input card_number">
    <label for="card_number">Card number</label>
    <%= text_field_tag :card_number %>
</div>
<div class="input card_cvc">
    <label for="card_code">Security code (CVC)</label>
    <%= text_field_tag :card_cvc %>
</div>
<div class="input card_dates">
    <label>Card expiration date</label>
    <%= select_month nil, { add_month_number: true }, { id: "card_month"} %>
    <%= select_year nil, { add_year: Date.today.year, end_year: Date.today.year + 15 }, { id: "card_year"} %>
</div>
<%= f.button :submit, "Register", class: "button" %>
<% end %>

你怎么知道它会跳过你的方法？可能有例外。提升救援区中的例外情况。

def save_with_payment
    if valid?
    charge = Stripe::Charge.create({
     amount: 400.00,
     currency: "gbp",
     card: stripe_card_token,
     description: email
    })
    save
   end
   rescue Exception => e
    raise e
    false
  end
