我有一个简单的应用程序，其中用户A可以添加优惠，用户B可以为这些优惠生成优惠券，我对编码和东西一无所知所以我雇用了一个为我创建了这个系统的程序员，一切正常很棒，但后来我在我的应用程序中集成了AWS，突然生成优惠券按钮停止工作，它在Localhost上工作正常，但在heroku上没有，我的程序员现在不在这里。
每当我点击按钮为此优惠生成优惠券时 它带我到一个页面说：
The page you were looking for doesn't exist.
You may have mistyped the address or the page may have moved.
If you are the application owner check the logs for more information.
我检查了heroku日志：

您正在发出GET个请求，但您已在路由中指定提供POST请求。
修改
您的OffersController generate_coupon操作实际更新了属性，因此请将您的路线更改为put（请参阅下面的路线更改）：
<强>路由
resources :offers do
get '/offers/:id', to: 'offers#show'
member do
put 'generate_coupon'
end
end
将method: :put添加到link_to：
<%= link_to "Generate Coupon For This Offer", generate_coupon_offer_path(offer), method: :put, class: "btn btn-success", style: "margin-top: 20px; color: #fff", remote: true %>
为了处理ActionView::MissingTemplate (Missin

确保您在views/offers/generate_coupon.js.erb
<强>的application.js
//= require jquery

用两种不同的方法完成工作。一个用于显示数据，另一个用于更新记录。
def show
@offer = Offer.find(params[:id])
end
def create
@offer.update_attributes(coupon: @offer.generate_coupon) if
@offer.coupon.blank?
end
将该js文件更改为create.js.erb。
只需明确并将方法与资源分开，看看它是否完美运行。让我知道进展情况。
