Ruby on rails Rails使用条件访问控制器的多视图

我有一个用户模型，除了标准的帐户信息外，还包括发货信息

我有三种不同的视图可以更新用户信息：

• 巫师
• 背景
• 帐目

我知道我应该使用REST模型，所以我尝试通过更新操作运行所有这些更新。一个问题是，在向导视图中，我需要调用条带API。我在更新控制器中有条带调用。但是现在，当用户试图在设置或帐户视图上更新他们的帐户时，更新控制器正在调用stripeapi，这显然不是我想要的

所以我试图做的是，插入一个条件来检查向导参数（：total_value）是否传入，如果传入，则向Stripe收费。如果不是，则只需更新用户数据。但我还没能让它起作用，它只是更新用户，而不是向Stripe收费

这是分离这些更新的正确方向吗？还是应该在用户控制器中创建自定义操作？这是怎么回事

用户\u控制器

def update
  if !params[:total_value].nil?
    if @user.update_attributes(params[:user])
      # flash[:success] = "Profile updated"
      sign_in @user
      # Value input by the user (in dollars)
      @userPrice = params[:user][:total_value]
      # Send full price in cents to Stripe
      @stripePrice = @userPrice.to_i * 100

      Stripe::Charge.create(
        :amount => @stripePrice,
        :currency => "usd",
        :card => params[:user][:stripe_card_token],
        :description => "Charge for service"
      )  
      redirect_to success_path
      flash[:success] = "Hurray!"
    else
      flash.now[:notice] = "Can not be saved, please enter information."
      render :new
    end
  elsif 
    if @user.update_attributes(params[:user])
      sign_in @user
      flash[:success] = "Profile updated"
      redirect_to account_path
    else
      flash[:error] = "Error"
    end
  end    
 end

我发现两个问题。首先是你的：

if！参数[：总值].nil？

应该是

除非参数[：user][：total_value].nil？

（我个人更喜欢

除非
而不是
如果！…
）

如Nishant在评论中所述。其次，您有一个
elsif
，并且该条件结束，而不检查任何内容。只需一个
就足够了。
在控制器中，您正在检查是否
！参数[：总值].nil？
。但它不应该是
！参数[：用户][：总值].nil？
Yep。成功了！非常感谢！我想我误解了参数的工作原理。（我是新手）你能告诉我哪里可以学到更多吗？
