自動生成的苗條設計錯誤

Question

當我使用devise's編輯用戶注冊slim文件時，出現此錯誤：

Started GET "/users/edit" for 127.0.0.1 at 2014-04-30 00:28:39 +0530
Processing by Devise::RegistrationsController#edit as HTML
User Load (0.2ms)  SELECT "users".* FROM "users" WHERE "users"."id" = 4 ORDER BY "users"."id" ASC LIMIT 1

用戶注冊瘦文件為：

h2
 | Edit #{resource_name.to_s.humanize}
= form_for(resource, as: resource_name, url: registration_path(resource_name), html: { method: :put }) do |f|
    = devise_error_messages!
    div
        = f.label :email
        br
        = f.email_field :email, autofocus: true
    - if devise_mapping.confirmable? && resource.pending_reconfirmation?
    div
        | Currently waiting confirmation for: #{resource.unconfirmed_email}
    div
        = f.label :password
        i (leave blank if you dont want to change it)
        br
        = f.password_field :password, autocomplete: "off"
    div
        = f.label :password_confirmation
        br
        = f.password_field :password_confirmation, autocomplete: "off"
    div
        = f.label :current_password
        i (we need your current password to confirm your changes)
        br
        = f.password_field :current_password, autocomplete: "off"
    div= f.submit "Update"
h3 Cancel my account
p
    | Unhappy? #{button_to "Cancel my account", registration_path(resource_name), data: { confirm: "Are you sure?" }, method: :delete}
= link_to "Back", :back

如何解決這個錯誤？

注意 ：此slim文件是自動生成的。

解決了。

錯誤在此行之后：

- if devise_mapping.confirmable? && resource.pending_reconfirmation?

div's沒有縮進，因此if塊不會結束，因此會出錯。
