ruby-on-rails – ActiveAdmin中的ArgumentError :: Devise :: Sessions #new Rails 4

我正在使用rails 4 activeadmin在 ruby 1.9.3p392上运行.

当我要去的时候

http://127.0.0.1:3000/admin/login

我得到一个错误：

ArgumentError in ActiveAdmin::Devise::Sessions#new

Showing C:/Ruby/lib/ruby/gems/1.9.1/bundler/gems/active_admin-85b9f8164809/app/views/active_admin/devise/sessions/new.html.erb where line #5 raised:

wrong number of arguments (3 for 2)

提取的来源(第5行)：

<h2><%= title "#{render_or_call_method_or_proc_on(self,active_admin_application.site_title)} #{t('active_admin.devise.login.title')}" %></h2>

<% scope = Devise::Mapping.find_scope!(resource_name) %>
<%= active_admin_form_for(resource,:as => resource_name,:url => send(:"#{scope}_session_path"),:html => { :id => "session_new" }) do |f|
  f.inputs do
    resource.class.authentication_keys.each { |key| f.input key,:input_html => {:autofocus => true}}
    f.input :password

解决方法

我在这里有同样的问题,我解决了从我的Gemfile中删除gem“Meta_search”.
