ruby-on-rails - 如何创建没有密码的用户并稍后使用 Devise 表单进行设置？

Question

我正在构建一个 Rails 应用程序，我想在没有密码的 Rails 控制台上创建用户，收到一封确认电子邮件，然后单击确认电子邮件中的链接，在我的网站上设置密码。 (我正在使用 Devise)

到目前为止，这是我尝试过的:

app/models/user.rb

class User < ApplicationRecord
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :validatable, :confirmable

  protected
  def password_required?
    confirmed? ? super : false
  end
end

app/controllers/users/confirmations_controller.rb

class Users::ConfirmationsController < Devise::ConfirmationsController
  protected
  def after_confirmation_path_for(resource_name, resource)
    sign_in(resource)
    edit_registration_path(resource)
  end
end

我特地做了 sign_in(resource) 因为我希望人们在这个过程中登录。

app/controllers/users_controller.rb

class UsersController < ApplicationController
    def create
    end
end

目前，当我通过 Rails 控制台创建用户然后单击确认链接时，我最终会进入设计 View ，以编辑我的帐户(更具体地说是我的密码)，这很好，但我不能不要验证表格，因为我必须填写我以前的密码才能更改它。但是由于我在创建过程中没有设置任何密码，所以我卡住了!

关于我如何做到这一点有什么想法吗？

谢谢

编辑

如评论中所述，我尝试使用“忘记密码”链接。它有效，但在设置密码后，用户必须登录(因此再次输入密码)。在我看来，这可能不是一个很好的客户体验，这就是为什么我想知道是否有一种方法可以做到这一点，就像我在我的帖子中解释的那样，或者一种在用户设置密码后登录的方法第一次。

更新

根据一些建议，我对我的文件进行了一些更改，但我仍然收到错误消息，提示当前密码不能为空。这是我的代码:

routes.rb

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

  devise_for :users, path: '', path_names: { sign_in: 'sign_in', sign_out: 
  'sign_out'}, controllers: { confirmations: 'users/confirmations', 
  registrations: 'users/registrations' }
end

app/controllers/users/confirmations_controller.rb

class Users::ConfirmationsController < Devise::ConfirmationsController
  def update_resource(resource, params)
    if resource.encrypted_password.present?
      super
    else
      resource.update(params)
    end
  end

  protected
  def after_confirmation_path_for(resource_name, resource)
    sign_in(resource)
    edit_registration_path(resource)
  end
end

用户.rb

class User < ApplicationRecord
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :validatable, :confirmable

  protected
  def password_required?
    confirmed? ? super : false
  end
end

app/views/devise/registrations/edit.html.erb

<h2>Edit your account</h2>

<div>
  <%= devise_error_messages! %>
  <%= form_for(resource, as: resource_name, url: registration_path(resource_name), html: { method: :put }) do |f| %>
    <p><%= current_user.first_name %> <%= current_user.last_name %></p>
    <p>Email address: <strong><%= current_user.email %></strong></p>

    <div class="container mb-5">
      <div class="row">
        <%= f.label :password %>
      </div>
      <div class="row">
        <%= f.password_field :password, autofocus: true, class: 'form-control', :required => 'required' %>
      </div>
    </div>

    <div class="container mb-5">
      <div class="row">
        <%= f.label :password_confirmation %>
      </div>
      <div class="row">
        <%= f.password_field :password_confirmation, autofocus: true, class: 'form-control', :required => 'required' %>
      </div>
    </div>



    <div class="container text-center mb-3">
      <%= f.submit "Update", class: 'navbar-cta' %>
    </div>
  <% end %>
</div>

Answer 1

完全不同的解决方案是使用 Devise::Invitable提供您可能正在寻找的功能。

它为您提供了一个 /users/invitation/new 路径，其中包含一个表单，您可以填写该表单来邀请用户。保存用户记录，然后用户通过接受邀请完成注册过程。

如果您真的想要，您可以从控制台发送邀请:

User.invite!(email: 'someone@example.com')

但实际上我只想使用 Pundit 或 CanCanCan 设置一些基本授权来锁定邀请 Controller 并通过 GUI 完成。无论如何，您很可能会需要它。
