我有一个用户模型，除了标准帐户信息外，还包括运输信息。
我有三个不同的视图可以更新用户的信息：
- 向导
- 设置
- 帐户
我知道我应该使用 REST 模型，因此我尝试通过 Update 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 Stripe API。所以我在 Update 控制器中有那个 Stripe 调用。但是现在当用户尝试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 Stripe API，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是否正在传递向导参数之一（：total_value），如果是，则向Stripe收费。如果不是，那么只需更新用户数据。但我无法让它工作，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？或者我应该在用户控制器中创建自定义操作？这是如何运作的？
users_controller
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
