我正在尝试创建一个从 1 个控制器提交到另一个控制器的表单。当我这样做时，我得到“nil:NilClass 的未定义方法'allow_forgery_protection'”。但是，如果我 POST 回同一个控制器，它会成功提交。
要知道的事情
我的应用程序控制器已
protect_from_forgery设置。我不是:before_filter为了减少可能出现的问题而搞砸或做任何事情。两种控制器都没有型号。两者都是用
rails g controller <name>- Rails 3.2 如果它有所作为
应用程序/控制器/first_controller.rb
def myaction
end
app/views/first/myaction.html.erb
<%= form_tag(url_for(:controller => 'second', :action => controller.action_name), :method => :post) do %>
<fieldset>
<%= label_tag(:file_dir, "File location") %>
<%= text_field_tag :file_dir, "/var/log" %>
</fieldset>
<%= submit_tag "Submit" %>
<% end %>
应用程序/控制器/second_controller.rb
def myaction
end
app/views/second/myaction.html.erb
<h1>Second#myaction</h1>
<p>Find me in app/views/second/myaction.html.erb</p>
路线.rb
match 'first/:action' => 'first#:action'
match 'second/:action' => 'second#:action'
It's probably my lack of understanding about the CSRF, but I don't see how simply changing :controller => 'second'to :controller => 'first' will determine whether the nearly identical controllers will work.
