ruby-on-rails - 我的 Rails 4 应用程序上的每个 link_to 都被调用了两次

Question

我的 Rails 4 应用程序遇到一些异常行为。每次我单击 View 中的 link_to 时，我的 Controller 操作都会被调用两次。例如:

在我的 root_url 中，我对 users_profile 有这个标准调用:

<%= link_to('User Profile', users_profile_path, :class => "logout-button") %>

当我单击此链接时，我的控制台显示以下输出:

Started GET "/users/profile" for 127.0.0.1 at 2013-11-25 20:45:53 -0200
Processing by Users::SessionsController#profile as HTML
  User Load (0.7ms)  SELECT "users".* FROM "users" WHERE "users"."id" = 45 ORDER BY "users"."id" ASC LIMIT 1

当有远程(例如 JS)调用方法时，人们经常会出现这种行为，但我不是这种情况。最奇怪的是，如果我将直接 URL 放到浏览器上的 users_profile_path 中。我的 Rails 控制台只收到一个请求:

Started GET "/users/profile" for 127.0.0.1 at 2013-11-25 20:48:17 -0200
Processing by Users::SessionsController#profile as HTML
  User Load (0.3ms)  SELECT "users".* FROM "users" WHERE "users"."id" = 45 ORDER BY "users"."id" ASC LIMIT 1
  InvestorProfile Load (0.3ms)  SELECT "investor_profiles".* FROM "investor_profiles" WHERE "investor_profiles"."user_id" = $1 ORDER BY "investor_profiles"."id" ASC LIMIT 1  [["user_id", 45]]
  EmployeeProfile Load (0.2ms)  SELECT "employee_profiles".* FROM "employee_profiles" WHERE "employee_profiles"."user_id" = $1 ORDER BY "employee_profiles"."id" ASC LIMIT 1  [["user_id", 45]]
  Rendered users/sessions/_investor_setup.html.erb (3.4ms)
  Rendered users/sessions/profile.html.erb within layouts/application (4.2ms)
Completed 200 OK in 12ms (Views: 7.7ms | ActiveRecord: 1.1ms)

我的应用程序中的每个链接都得到相同的结果，而不仅仅是这个。

Answer 1

rails 5/6

当我点击一个链接时，整个 Controller 被调用了两次。我尝试了接受的答案，但它对我不起作用，所以我只是设置 turbolinks: false 如下:

<%= link_to("Demo", @user, data: { turbolinks: false } ) %>
