這是從我的登錄頁面代碼：我在哪裏得到一個NoMethodError使用平靜的授權？
<%= flash[:notice]%>
<h1>System</h1>
<%= Time.now%></p>
<p><%=link_to "Register", signup_path%></p>
<div id="login">
<%if logged_in? %>
<b><%=current_user.login%></b>
<%=link_to "Signout", logout_path%>
<%else%>
<% form_remote_tag :url => session_path do -%>

<%= check_box_tag 'remember_me', '1', @remember_me %></p>
<p><%= submit_tag 'Log in' %></p>
<% end -%>
<%end%>
</div>
這是sessions_controller.rb：
# This controller handles the login/logout function of the site.
class SessionsController < ApplicationController
# Be sure to include AuthenticationSystem in Application Controller instead
#include AuthenticatedSystem
# render new.rhtml
def new
end
def create
logout_keeping_session!
user = User.authenticate(params[:login], params[:password])
if user
# Protects against session fixation attacks, causes request forgery
# protection if user resubmits an earlier form using back
# button. Uncomment if you understand the tradeoffs.
# reset_session
self.current_user = user
new_cookie_flag = (params[:remember_me] == "1")
handle_remember_cookie! new_cookie_flag
#redirect_back_or_default('/')
flash[:notice] = "Logged in successfully"
self.reload_login()
else
note_failed_signin
@login = params[:login]
@remember_me = params[:remember_me]
render :action => 'new'
end
end
def destroy
logout_killing_session!
flash[:notice] = "You have been logged out."
redirect_back_or_default('/')
end
def reload_login
respond_to {|format| format.js}
flash[:notice] = "What the hell?"
end
protected
# Track failed login attempts
def note_failed_signin
flash[:error] = "Couldn't log you in as '#{params[:login]}'"
logger.warn "Failed login for '#{params[:login]}' from #{request.remote_ip} at #{Time.now.utc}"
end
end
我可以登錄的頁面，但在我等了一會，幾分鐘後，我發現我的系統＃指標差得NoMethodError ...
undefined method `remember_token?' for true:TrueClass
Extracted source (around line #6):
3: <%= Time.now%></p>
4: <p><%=link_to "Register", signup_path%></p>
5: <div id="login">
6: <%if logged_in? %>
7: <b><%=current_user.login%></b>
8: <%=link_to "Signout", logout_path%>
9: <%else%>
我不知道發生了什麼事情錯了，它工作在首次發射。但是如果我再次登錄「http://localhost:3000/login」，錯誤消失了，發生了什麼？謝謝你。
