Question

<%= link_to 'show', :controller=>:users, :action=>:show, :id=>u.id, :confirm=>'are you sure?' %>
<%= link_to 'reset pass.', :controller=>:users, :action=>:reset_password, :id=>u.id, :confirm=>'RESET PASSWORD, are you sure?' %>

第一个链接工作正常，但第二个链接真的很奇怪...有时它可以工作，有时却不会导致这样的错误：

UsersController中的LoadError #index

预期   /home/anonym/Documents/RubyOnRails/authorisation/loginout/app/controllers/users_controller.rb   定义UsersController

此外，它不显示确认框。无论如何，如果我删除：确认选项，不时会发生第一个错误。

控制器：

#users_controller.rb
class UsersController < ApplicationController
...
def reset_password
    @user=User.find_by_id(params[:id])
...

路线：

#routes.rb
match 'users/:id/reset_password', :to=>"users#reset_password"

如果它每次失败都可以理解，但它是随机的。

任何想法为什么？

更新

控制器中的这个小修改似乎解决了这个问题。

#Thread.new{UserMailer.reset_password(@user, passwd).deliver}
UserMailer.reset_password(@user, passwd).deliver

这也导致我的sqlite数据库崩溃（如果我非常快地点击链接几次）。

你知道为什么这个帖子可能是这样的杀手吗？

还有一个问题，为什么没有确认框？

在该数据库中断后 - 服务器重启无效。这种情况经常发生，尽管我不再使用线程。

Answer 1

Rails不是线程安全的。如果您需要执行后台操作，请使用Spawn或DelayedJob

之类的内容

至于确认，您的 app / assets / javascript 文件夹中是否有application.js，并且＆lt; head＆gt;中是否有<%= javascript_include_tag "application" %>？你的布局？

如果没有加载application.js文件，则不会运行任何Rails JS，其中包括确认。

更新：我现在看到了问题。 link_to方法有两种类型的选项，首先是路由选项，然后是HTML的选项。 ：确认是HTML选项之一。

如果您要传递路由和HTML选项，则需要先将路由选项分隔为自己的哈希值，如下所示：

<%= link_to 'show', { :controller=>:users, :action=>:show, :id=>u.id }, :confirm=>'are you sure?' %>

<%= link_to 'reset pass.', { :controller=>:users, :action=>:reset_password, :id=>u.id }, :confirm=>'RESET PASSWORD, are you sure?' %>

正如日志所示，您的确认将作为link_to生成的路径的一部分传递，而不是包含在生成的 a 元素的HTML中。

我的link_to有问题吗？
