Rails 3.2
Devise
Devise security extensions

在我的app / views / users / shared / _links.slim中,我有:

- if devise_mapping.lockable? && resource_class.unlock_strategy_enabled?(:email) && controller_name != 'unlocks'
  li.home-nav= link_to t('users.shared.didnt_received_unlock'), new_unlock_path(resource_name)

在我的用户模型中,我有:

devise :database_authenticatable, :registerable,
     :recoverable, :rememberable, :trackable,  :invitable, :confirmable,
     :password_expirable, :password_archivable, :session_limitable, :expirable, :secure_validatable,
     :lockable, :timeoutable

当用户尝试登录时,出现以下错误:

NameError(未定义的局部变量或方法resource_class' for #<#<Class:0x000000098a1598>:0x000000092d4b60>): app/views/users/shared/_links.slim:5:in _ app_views_users_shared__links_slim___1531266065579142927_70700660'   app / views / layouts / application.html.slim:96:在_app_views_layouts_application_html_slim___452855375923455357_79638440' app/middleware/catch_json_parse_errors.rb:8:in通话中

有什么想法吗?

resource_class仅在Devise控制器中可用,而在_links.slim视图中不可用。请改用User.unlock_strategy_enabled?(:email)
