Question

我一直在寻找这个bug有点...我的辅助方法似乎没有定义。或它们定义不正确。 user_unlock_url是一个具体示例。

我的控制器遵循维基：

class MyDeviseMailer < Devise::Mailer
  helper :application # gives access to all helpers defined within `application_helper`.
  include Devise::Controllers::UrlHelpers # Optional. eg. `confirmation_url`
  # Ensure that the mailer uses the devise views
  default template_path: 'devise/mailer'
  ...
end

但是调用它时会失败

我检查了助手是否正确初始化：

> mappings = Devise.mappings.values.map(&:used_helpers).flatten.uniq
=> [:session, :password, :registration, :unlock, :authy, :passwords_with_policy, :invitation]

> routes = Devise::URL_HELPERS.slice(*mappings)
=> {:session=>[nil, :new, :destroy],
 :password=>[nil, :new, :edit],
 :registration=>[nil, :new, :edit, :cancel],
 :unlock=>[nil, :new],
 :authy=>[],
 :passwords_with_policy=>[],
 :invitation=>[nil, :new, :accept]} 

> routes.each do |module_name, actions|
*   [:path, :url].each do |path_or_url|
*     actions.each do |action|
*       action = action ? "#{action}_" : ""
*       puts "#{action}#{module_name}_#{path_or_url}"
*     end
*   end
* end

...
unlock_path
new_unlock_path
unlock_url
new_unlock_url
...

似乎已包含在内，但是为什么要user_放在前面？这似乎是我的问题，但我不知道为什么。

我的邮件发送者肯定使用了正确的值：

<p><%= link_to 'Unlock my account', unlock_url(@resource, unlock_token: @token, host: @site_host) %></p>

Answer 1

您的devise_for中有什么？

  devise_for :users, :path=> 'members', only: :omniauth_callbacks, controllers: {omniauth_callbacks: 'omniauth_callbacks'}

devise_for（：user）被添加到路径和URL帮助器之后会发生什么

设计自定义类中未定义的辅助方法
