设计 after_sign_up_for 路径不起作用答案

【问题标题】：Devise after_sign_up_for path not working设计 after_sign_up_for 路径不起作用

【问题描述】：

我阅读了所有关于此的主题，但我仍然无法弄清楚哪里出了问题。我已经阅读了所有设计实施指南并遵循了它们，但是在新用户注册后，重定向会转到用户控制器，特别是 users#show。

对新注册的初始调用是通过我的注册控制器进行的。这已经得到验证。但是在注册之后它不会再次通过注册控制器。它通过用户控制器。我在新的注册控制器中中断了两个覆盖方法，但它们从未成功。

/routes.rb

Rails.application.routes.draw do
  root to: 'app#index'

  devise_for :users, controllers: { registrations: "registrations" }

  resources :users do
    member do
      put 'follow', to: 'users#follow'
      put 'unfollow', to: 'users#unfollow'
    end
  end

end

registrations_controller.rb

class RegistrationsController < Devise::RegistrationsController
protected
  #call for new registration does pass through here
  #after new registration does not pass through here


  def after_inactive_sign_up_path_for(resource)
    #never gets here after new registration
    other_path(resource)
  end

  def after_sign_up_path_for(resource)
    #never gets here after new registration
    other_path(resource)
  end

end

新的注册表：

  <form action="index.html">

    <%= form_for(resource, as: resource_name, url: registration_path(resource_name)) do |f| %>
      <%= devise_error_messages! %>

    <div class="form-group">
      <%= f.email_field :email, autofocus: true, placeholder: "Email", class: "form-control rounded input-lg text-center no-border" %>
    </div>

    <div class="form-group">
      <% if @minimum_password_length %>
      <em>(<%= @minimum_password_length %> characters minimum)</em>
      <% end %><br />
      <%= f.password_field :password, autocomplete: "off", placeholder: "Password", class: "form-control rounded input-lg text-center no-border" %>

    </div>

    <div class="form-group">
      <%= f.password_field :password_confirmation, autocomplete: "off", placeholder: "Confirm Password", class: "form-control rounded input-lg text-center no-border"  %>
    </div>

    <div class="checkbox i-checks m-b">
      <label class="m-l">
        <input type="checkbox" checked=""><i></i> Agree the <a href="#">terms and policy</a>
      </label>
    </div>

    <button type="submit" class="btn btn-lg btn-warning lt b-white b-2x btn-block btn-rounded"><i class="icon-arrow-right pull-right"></i><span class="m-r-n-lg">Sign up</span></button>
    <% end %>

    <div class="text-center m-t m-b"><small><%= link_to "Already have an account?", new_session_path(resource_name) %></small></div>

【问题讨论】：

粘贴完整的注册控制器。您的注册方法创建错误，表单应重定向到registrations create，但它会向用户显示，您的表单的网址错误。请粘贴表格
@Sravan 就是这样！！ index.html 有一个额外的前导表单标记。更新了上面的代码以供显示。额外的表单标签是前一段代码遗留下来的。
现在完成了吗？如果没有，您的注册控制器路径是什么

标签： ruby-on-rails devise

【解决方案1】：

如果你想去users#show，正确的路径助手应该是user_path(resource)，是你想要的吗？

【讨论】：

【解决方案2】：

看起来问题有两个方面。注册控制器正在寻找不正确的路径，但它也需要正确的 id。我认为这里的解决方案是将它传递给user_path(@user.id)，而不是在new_user_path(resource) 中将资源作为参数。

它正在尝试查询 ID 为“Index”但不存在的用户，因此会引发错误。您需要找到新用户的 id 并将其插入到路由中，以便找到该特定用户配置文件。我以@user 为例。您可以在代码中定义该变量或使用您希望的任何变量。希望对您有所帮助！
