无法确认子域的帐户。使用 Devise可确认和Rails 4

Question

我正在使用 Rails 4、带有 Apartment gem 的子域和 Devise (3.4.1)。我对 Devise Confirmable 生成的电子邮件确认链接有疑问。当用户创建帐户时，他们会收到一封电子邮件：

You can confirm your account email through the link below:

http://lvh.me:3000/users/confirmation?confirmation_token=xsTNUw5oQYTPf_CBwZXD

但是，它不起作用，因为用户的子域不在链接上，它应该是例如

http://mysubdomain.lvh.me:3000/users/confirmation?confirmation_token=xsTNUw5oQYTPf_CBwZXD

如果我在浏览器上手动添加子域链接，它会确认该帐户。

如何更改confirmation_instructions.html.erb link_to 以生成前面带有子域的confirmation_url？例如：

<p>Welcome <%= @email %>!</p>

<p>You can confirm your account email through the link below:</p>

<p><%= link_to 'Confirm my account', confirmation_url(@resource, :confirmation_token => @resource.confirmation_token, :subdomain => @resource.subdomain) %></p>

我尝试过例如https://github.com/plataformatec/devise/wiki/How-To:-Send-emails-from-subdomains和https://github.com/fortuity/rails3-subdomain-devise/wiki/Tutorial- %28Walkthrough%29但这对我来说都不起作用，我收到了错误：

 "NoMethodError in Accounts#create, undefined method `subdomain' for #<User:0x...>"

这是我的 AccountsController 中的创建操作：

def create
  @account = Account.new(account_params)
    if @account.valid? && verify_recaptcha
       Apartment::Tenant.create(@account.subdomain)
       Apartment::Tenant.switch(@account.subdomain)
       @account.save
       @account.create_default_lists
       redirect_to new_user_session_url(subdomain: @account.subdomain)
    else
       render action: 'new'
    end
end

这是我的路线：

user_confirmation     POST   /users/confirmation(.:format)                         devise/confirmations#create
new_user_confirmation GET    /users/confirmation/new(.:format)                   devise/confirmations#new
                      GET    /users/confirmation(.:format)                       devise/confirmations#show

在development.rb中我设置了：

config.action_mailer.default_url_options = { host: "lvh.me:3000" }

在应用程序控制器中我有：

protect_from_forgery
before_filter :authenticate_user!, :set_mailer_host

private

def current_account
   @current_account ||= Account.find_by(subdomain: request.subdomain)
end

helper_method :current_account

def set_mailer_host
   subdomain = current_account ? "#{current_account.subdomain}." : ""
   ActionMailer::Base.default_url_options[:host] = "#{subdomain}lvh.me:3000"
end

end

这是控制台上的错误：

ActionView::Template::Error (undefined method `subdomain' for #<User:0x007fbfcc27e5a0>):
    2: 
    3: <p>You can confirm your account email through the link below:</p>
    4: 
    5: <p><%= link_to 'Confirm my account', confirmation_url(@resource, :confirmation_token => @resource.confirmation_token, **:subdomain => @resource.subdomain**) %></p>
  app/views/devise/mailer/confirmation_instructions.html.erb:5:in `_app_views_devise_mailer_confirmation_instructions_html_erb___2999600516167812245_702'
  app/controllers/accounts_controller.rb:14:in `create'

Answer 1

我设法通过在confirmation_instructions.html.erb中使用以下内容来解决这个问题。这适用于我的设置，因为我使用的是 Apartment gem：

<%= link_to 'Confirm my account', user_confirmation_url(confirmation_token: @token, subdomain: Apartment::Tenant.current) %>
