紅寶石，條紋和javascript

Question

如何將該腳本以紅寶石形式合併，以便條紋收費如果不創建貼子，則不會通過。

現在，如果我刪除驗證帖子發佈如果收費經過，如果收費不通過帖子不張貼。

只要我添加驗證和缺少的東西，通過點擊付費時，收費是正確的，驗證停止在數據庫中保存後，但收費仍然通過。

validates :name, :phone_number, :post, presence: true 

    validates :email,

Answer 1

你需要包括begin和end在你的try/catch塊的rescue或我不相信它會正常工作：

begin 
    charge = Stripe::Charge.create(
    :customer => customer.id, 
    :amount  => @amount, 
    :description => 'Rails Stripe customer', 
    :currency => 'usd' 
) 

rescue Stripe::CardError => e 
    flash[:error] = e.message 
    redirect_to new_charge_path 
end 

您可能還需要確認params[:stripeEmail]和params[:stripeToken]實際上包含（預期的）東西，你嘗試創建客戶之前。

Answer 2

您需要將if塊中的條紋交互放入@post.save。這樣的事情：

def create 
    @post = Post.new(post_params) 

    if @post.save 
    # Amount in cents 
    @amount = 150 

    begin 
     customer = Stripe::Customer.create(
     :email => params[:stripeEmail], 
     :source => params[:stripeToken] 
    ) 

     charge = Stripe::Charge.create(
     :customer => customer.id, 
     :amount  => @amount, 
     :description => 'Rails Stripe customer', 
     :currency => 'usd' 
    ) 

     redirect_to @post, notice: 'Your post was created.' 
    rescue Stripe::CardError => e 
     flash[:error] = e.message 
     redirect_to new_charge_path 
    end 
    else 
    render :new 
    end 

此外，我需要評論的事實，這並不真正屬於控制器。我會建立一個類來處理Stripe交互。

這樣的話，在你的控制器，你會碰到這樣的：

if @post.save 
    begin 
    MyStripeStuff.create_and_charge_customer({ 
     email: params[:stripeEmail], 
     token: params[:stripeToken], 
     amount: 150, 
     currency: 'usd', 
     description: 'Rails Stripe customer' 
    }) 
    redirect_to @post, notice: 'Your post was created.' 
    rescue Stripe::CardError => e 
    flash[:error] = e.message 
    redirect_to new_charge_path 
    end 
else 
    render :new 
end
