Question

我在使用我的rails应用程序设置Stripe的订阅时遵循Railscast＃288。当我输入/ subscriptions / new？plan_id = monthly我收到了

ActiveRecord::RecordNotFound error Couldn't find Plan with id=monthly.

除了将文件添加到application.html.erb之外，我都遵循了所有内容。我在条带文档中找不到这些信息所以我假设教程的一部分已经过时（加上那与我当前的错误无关）。

控制器：

class SubscriptionsController < ApplicationController
  def new
    plan = Plan.find(params[:plan_id])
    @subscription = plan.subscriptions.build
  end

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

  def show
    @subscription = Subscription.find(params[:id])
  end
end

控制器：

class PlansController < ApplicationController
  def index
    @plans = Plan.order("price")
  end
end

路线：

  resources :subscriptions
  resources :plans

型号：

class Plan < ActiveRecord::Base
  has_many :subscriptions
end

型号：

class Subscription < ActiveRecord::Base
   belongs_to :plan
    validates_presence_of :plan_id
    validates_presence_of :email

    attr_accessor :stripe_card_token

    def save_with_payment
      if valid?
        customer = Stripe::Customer.create(description: email, plan: plan_id, card: stripe_card_token)
        self.stripe_customer_token = customer.id
        save!
      end
    rescue Stripe::InvalidRequestError => e
      logger.error "Stripe error while creating customer: #{e.message}"
      errors.add :base, "There was a problem with your credit card."
      false
    end
  end

new.html.erb：

<h1>Signing up for "<%= @subscription.plan.name %>"</h1>
<p>Includes <strong><%= @subscription.plan.length %> Subscription</strong> for only <strong><%= number_to_currency @subscription.plan.price %></strong> per month!</p>

<%= form_for @subscription do |f| %>
  <% if @subscription.errors.any? %>
    <div class="error_messages">
      <h2><%= pluralize(@subscription.errors.count, "error") %> prohibited this subscription from being saved:</h2>
      <ul>
      <% @subscription.errors.full_messages.each do |msg| %>
        <li><%= msg %></li>
      <% end %>
      </ul>
    </div>
  <% end %>

  <%= f.hidden_field :plan_id %>

  <%= f.hidden_field :stripe_card_token %>

  <div class="field">
    <%= f.label :email %>
    <%= f.text_field :email %>
  </div>
  <% if @subscription.stripe_card_token.present? %>
    Credit card has been provided.
  <% else %>
    <div class="field">
      <%= label_tag :card_number, "Credit Card Number" %>
      <%= text_field_tag :card_number, nil, name: nil %>
    </div>
    <div class="field">
      <%= label_tag :card_code, "Security Code on Card (CVV)" %>
      <%= text_field_tag :card_code, nil, name: nil %>
    </div>
    <div class="field">
      <%= label_tag :card_month, "Card Expiration" %>
      <%= select_month nil, {add_month_numbers: true}, {name: nil, id: "card_month"} %>
      <%= select_year nil, {start_year: Date.today.year, end_year: Date.today.year+15}, {name: nil, id: "card_year"} %>
    </div>
  <% end %>
  <div id="stripe_error">
    <noscript>JavaScript is not enabled and is required for this form. First enable it in your web browser settings.</noscript>
  </div>
  <div class="actions">
    <%= f.submit "Subscribe" %>
  </div>
<% end %>

schema.rb：

  create_table "subscriptions", force: true do |t|
    t.integer  "plan_id"
    t.string   "email"
    t.string   "stripe_customer_token"
    t.datetime "created_at"
    t.datetime "updated_at"
  end

  create_table "plans", force: true do |t|
    t.string   "name"
    t.decimal  "price",      precision: 10, scale: 0
    t.integer  "length"
    t.datetime "created_at"
    t.datetime "updated_at"
  end

Answer 1

我认为plan_id应该是一个整数，而不是'月'，所以它应该是与计划相对应的id

除非您使用gem，否则您还需要将js文件的行添加到application.html.erb文件中。

您应该查看条带文档以查看更改。

我认为有轨电视有点过时了。

Answer 2

在查询字符串中，您将monthly值传递为plan_id（应为id）。如果要传递计划名称，可以将查询更改为：/subscriptions/new?plan=monthly

并将您的控制器更改为：

class SubscriptionsController < ApplicationController
  def new
    plan = Plan.find_by!(name: params[:plan])
    @subscription = plan.subscriptions.build
  end
...

Answer 3

您尝试使用id方法通过find找到记录，而params[:plan_id]看起来像name列。您有两个选择：

发送计划ID：

?plan_id=1
更改加载计划实例的方式：

Plan.find_by!(name: 'monthly')

无法找到ID =每月的计划
