Rails 3 表单的简单自定义发布操作

Question

我在不需要视图的表单控制器操作上遇到ActionView::MissingTemplate 错误，因为它将参数数据传递给控制器​​，然后控制器将发布 API 请求。

# Newsletter controller

def index
end

def subscribe
  Gibbon.list_subscribe({:id => "my-list-id", :email_address => params[:email]})
end

在我的路线中：

# Routes
match "/subscribe", to: "newsletter#subscribe", :via => :post

查看我的表单所在的位置

# newsletter/index.html.erb
<%= form_tag subscribe_path, class: "form", remote: true do %>
    <%= text_field_tag :email, nil, :class => 'email', :type=>"email", :placeholder => 'Sign up for newsletter' %>
    <%= submit_tag "Go", class: "submit-button"%>
<% end %>

从通讯索引页面有一个表单，我想要它做的就是将用户电子邮件地址的请求发送到我的订阅操作

Error:

Searched in:
  * "/Code/myapp/app/views"
):

以上是我收到的错误。我想知道如何假装这个模板问题，因为该操作不需要视图。

感谢您的帮助。

你可以试试这个

def subscribe
  if request.post?
    Gibbon.list_subscribe({:id => "my-list-id", :email_address => params[:email]})
    redirect_to root_url, :notice => 'Success'
  else
    redirect_to some_place
  end
end

在你的路线中

post "/subscribe", to: "newsletter#subscribe"

检查您的路线以双重确认
