Question

我的控制器中有一个功能，我会渲染到另一个名为thankyou的页面。渲染工作正常，但在那之后rails再次将我重定向到thankyou，但这次它找不到模板。我无法理解为什么rails会将两次渲染给同一个模板，结果不同。这是我的功能：

def create
amount = params[:amount]
nonce = params[:payment_method_nonce]
if nonce.nil?
  render :checkout
else
  result = Braintree::Transaction.sale(
    amount: amount,
    payment_method_nonce: nonce
  )
  session[:user_id] = nil
  render :thankyou
end
end

这是调用动作创建的表单：

<%= form_tag '/create', remote: true, id: "form", method: "post" do %>
 <div class="col-md-12 text-left">
  Choose you plan: <br>
  <div>
  <input class="collection_radio_buttons" id="plan_pro" name="amount" type="radio" value="0.99">
  <label for="plan_pro">
  <span class="fa-stack"><i class="fa fa-circle-o fa-stack-1x"></i><i class="fa fa-circle fa-stack-1x"></i></span>
  <b>Pro</b><br>
  </label>
  </div>
  <div>
  <input class="collection_radio_buttons" id="plan_premium" name="amount" type="radio" value="1.98" checked="checked">
  <label for="plan_premium">
  <span class="fa-stack"><i class="fa fa-circle-o fa-stack-1x"></i><i class="fa fa-circle fa-stack-1x"></i></span>
  <b>Premium</b><br>
  </label>
  </div>
  <div>
   <div id="paypal-container"> </div>
  <input data-braintree-name="number" placeholder="Card number" class="string optional form-control input-box mailcode-form" maxlenght="16">
  <input data-braintree-name="cvv" placeholder="CVV" class="string optional form-control input-box mailcode-form" width="3" maxlenght="3">
  <input data-braintree-name="expiration_date" placeholder="Expiration date (e.g. 10/20)" class="string optional form-control input-box mailcode-form">
 </div>
  <div class="col-md-12 pull-right">
     <input type="submit" class="signup-next" id="button_1" value="Pay 0,99 €">
     <input type="submit" class="signup-next" id="button_2" value="Pay 1,98 €">
  </div>
<% end %>

PS：从日志中看来，rails称为action创建了两次。这是我提交表单后的实际日志：

Answer 1

在你的app / views / home / thankyou.js.erb文件中试试：

$('#signup-modal .modal-body').html("<%= j render_to_string('thankyou') %>");

在:create行动中：

render js: :thankyou

Answer 2

尝试渲染thanyou模板，如下所示：

Answer 3

The method is simply called twice. You have to check why on the client side. You will probably see two calls in the developer console of your browser.

Answer 4

我已修复删除 remote：true 的问题。现在我只有一个电话（HTML）。我还删除了部分 _checkout.html.erb ，我已替换为名为 checkout.html.erb 的文件

Ruby缺少模板
