Rails 应用程序中的路由错误答案

【问题标题】：Route Error within Rails AppRails 应用程序中的路由错误
【发布时间】：2015-11-13 19:11:38
【问题描述】：

在安装 Elasticsearch（运行良好）的过程中，退出我的应用程序的功能不再起作用。我收到以下错误消息。

    No route matches [GET] "/users/sign_out"

    Rails.root: C:/Users/mdavis/workspace/intakelog

    Application Trace | Framework Trace | Full Trace

    Routes match in priority from top to bottom

当我运行 Rake Routes 时，我看到了正确的路径。

【问题讨论】：

你有default.js文件吗
我不明白为什么它在寻找 javascript/default.js 而不是 assets/default.js
您在哪里调用您的注销？你用link_to(signout_path, :method => "delete")
<li> <%= link_to "Sign out", destroy_user_session_path, :method => :delete, class: "fa fa-sign-out" %></li>
有趣：这似乎是以前的问题，以前的 OP 也没有解决。 stackoverflow.com/questions/19749311/…

【解决方案1】：

如果您有default.js，可能是您的应用程序想要先预编译它。

如果是这样，您必须在 config/initializers/assets 中设置它

Rails.application.config.assets.precompile += %w( default.js )

【讨论】：

我从来没有 default.js 文件。
我怀疑它与我的 application.html.erb 文件中的<%= javascript_include_tag "default", "data-turbolinks-track" => true %> 有关，但我不知道为什么。这是唯一不起作用的功能。
对不起，我刚看到ActionController::RoutingError (No route matches [GET] "/javascripts/default.js") 所以我以为你在那里遇到了麻烦^^)
我是否应该在一切正常时回滚并尝试重做 Elasticsearch 和 searchkick 的步骤？
当然，反复试验始终是一种选择，尤其是当您无法找到它的路线时。我自己也不确定错误可能出在哪里......

【解决方案2】：

路由缺失消息的请求方法为[GET]：

No route matches [GET] "/users/sign_out"

但是你的路由定义只接受 DELETE 方法：

destroy_user_session DELETE /users/sign_out(.:format)
new_user_session GET    /users/sign_in(.:format)
user_session POST   /users/sign_in(.:format)
destroy_user_session DELETE /users/sign_out(.:format)

因此，向该 url 发出 GET 请求是无效路由。

【讨论】：

在 cmets 中，OP 说明了她/他是如何调用路由的，并且他/她说它在 link_to 中使用 :method => :delete 调用...
@James Milani 在我使用 Windows 工作站上的 searchkick gem 安装 Easticsearch 之前，一切正常。但是，在此之前，我从 Linux 工作站创建了整个应用程序。我不确定这是否会有所不同。

【解决方案3】：

这个问题的解决方案是 <%= javascript_include_tag 'application' %> 没有在 application.html.erb 文件中正确地说明。我需要简化<%= javascript_include_tag "default", "data-turbolinks-track" => true %>。我不知道为什么我需要对其进行更改才能使其正常工作。
