找不到計劃id =每月

Question

我在Railscast＃288中使用我的Rails應用程序設置Stripe的訂閱。當我輸入/訂閱/新？plan_id的數據類型=月我收到一個

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

我注視着將文件添加到application.html.erb之外的一切。我無法在條紋文檔中找到這些信息，所以我認爲教程的​​一部分已經過時（加上那與我當前的錯誤無關）。

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 

途徑：

resources :subscriptions 
    resources :plans 

型號：

class Plan < ActiveRecord::Base 
    has_many :subscriptions 
end 

型號：

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>

    <% end %>

    <div class="field">

    </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

在您的查詢字符串中，您傳遞的monthly值爲plan_id（應該是id）。如果你想通過計劃的名稱，你可以改變你查詢到看起來像：使用通過id

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

Answer 2

我相信plan_id的數據類型應該是一個整數，而不是 '月月'，所以它應該是與計劃對應的ID

您還需要將js文件的行添加到application.html.erb文件中unl你使用寶石。

您應該看看條紋文檔以查看更改。

我相信railscast有點過時了。

Answer 3

你試圖查找記錄：/subscriptions/new?plan=monthly

，改變你的控制器看起來像find方法和您的params[:plan_id]看起來像name列。你有兩個選擇：

• 發送計劃ID：

  ?plan_id=1

• 更改您加載計劃實例的方式：

  Plan.find_by!(name: 'monthly')
