如何使用devise生成恢复密码的链接？

gem 'devise'

rails generate devise:install

rails generate devise User

rails db:migrate

devise :recoverable, :rememberable, :trackable

config.action_mailer.default_url_options = { host: 'localhost', port: 3000 }
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
  address:              'smtp.gmail.com',
  port:                 587,
  domain:               'example.com',
  user_name:            '<your-email>',
  password:             '<your-password>',
  authentication:       'plain',
  enable_starttls_auto: true
}

<%= form_for(resource, as: resource_name, url: password_path(resource_name), html: { method: :post }) do |f| %>
  <div class="field">
    <%= f.label :email %><br />
    <%= f.email_field :email, autofocus: true, autocomplete: "email" %>
  </div>
  <div class="actions">
    <%= f.submit "Send me reset password instructions" %>
  </div>
<% end %>

<p>Hello <%= @resource.email %>,</p>

<p>Someone has requested a link to change your password. You can do this through the link below.</p>

<p><%= link_to 'Change my password', edit_password_url(@resource, reset_password_token: @token) %></p>

<p>If you didn't request this, please ignore this email.</p>

<p>Your password won't change until you access the link above and create a new one.</p>

<p>Thanks,</p>

<p>Your Application Team</p>
