問題解決Rails的3&設計:當註銷
klaustopher他的回答解決了這個問題的錯誤。
的問題是,當我有<%,我不能退出= current_user.email%>或<%= current_user.username $>在我的佈局/ application.html.erb
當我從我的application.html.erb中刪除了這一行,我可以無誤地註銷。 我在谷歌搜索,但找不到這個問題的任何事情。
我application.html.erb:
<!DOCTYPE html>
<html id="html">
<head>
<title><%= content_for?(:title) ? yield(:title) : "Contractbeheersysteem" %></title>
<%= stylesheet_link_tag "application", "simple_form", "gegevens", "drop-down-menu", "table", :media => "all" %>
<%= javascript_include_tag "autocomplete-rails.js" %>

謝謝,作爲初學者,這對我來說有點棘手。我希望其他人對此主題有所瞭解。 –
