user_signed_in?总是返回false [英] user_signed_in? always returns false
问题描述
我一直在追踪这些轨道。
I have been following these railscasts
http://railscasts.com/episodes/209-introducing-devise &&
http://railscasts.com/episodes/233-engage-with-devise
用于用户身份验证,但是每当我尝试查看用户是否登录时,响应始终为false。
http://railscasts.com/episodes/209-introducing-devise && http://railscasts.com/episodes/233-engage-with-devise for user authentication, however whenever I try to see if a user is signed in, the response is always false.
我尝试了一堆的事情来解决这个问题。我尝试过不同版本的devise和devise_rpx_connectable。我尝试在配置文件中更改设置。我尝试运行rails生成设计:安装一段时间与不同的宝石版本。
I tried a bunch of things to try remediating this issue. I tried different versions of devise and devise_rpx_connectable. I tried changing settings around in the configuration file. I tried running 'rails generate devise:install' a bunch of times with different gem versions.
奇怪的是,当我将RPXNow.api_key变成一些假的,我没有收到错误,这是意想不到的行为。
The weird thing is that when I change around the RPXNow.api_key to something bogus, I don't get an error, which is unexpected behavior.
这是我的application.html.erb文件中的代码:
Here is the code in my application.html.erb file:
<% if user_signed_in? %>
Signed in as <%= current_user.email %>. Not you?
<%= link_to "Sign out", destroy_user_session_path %>
<% else %>
<%= link_to_rpx "Sign in", user_session_url %>
<% end %>
<%= javascript_include_rpx(root_url) %>
以下是我的用户模型user.rb文件中的代码
Here is the code in my user model user.rb file
class User < ActiveRecord::Base
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable, :rpx_connectable
attr_accessible :email, :password, :password_confirmation
validates :email, :uniqueness => true
.....other stuff....
end
这是我的宝石文件的一部分:
Here is part of my Gemfile:
gem 'rails', '3.2.6'
gem 'devise','2.0.0'
gem 'devise_rpx_connectable'
devise_rpx_connectable gem版本0.2.2
and this gets the devise_rpx_connectable gem version 0.2.2
这是我的初始化器/ devise.rb文件中的内容:
Here is whats in my initializers/devise.rb file:
Devise.setup do |config|
config.mailer_sender = "please-change-me-at-config-initializers-devise@example.com"
config.apply_schema = false
require 'devise/orm/active_record'
config.case_insensitive_keys = [ :email ]
config.strip_whitespace_keys = [ :email ]
config.skip_session_storage = [:http_auth]
config.stretches = Rails.env.test? ? 1 : 10
config.reconfirmable = true
config.use_salt_as_remember_token = true
config.reset_password_within = 6.hours
config.sign_out_via = :delete
config.rpx_application_name = "appname"
RPXNow.api_key = "<any_key_we_want_apparently>"
end
这是在我们的routes.rb文件中:
And this is in our routes.rb file:
AppName::Application.routes.draw do
root :to => "pages#home"
match 'users/:id' => "users#index"
devise_for :users
end
ply的评论---
我做了rails g migration add_rpx_to_users rpx_identifier:string
--editted after ply's comment--- I did rails g migration add_rpx_to_users rpx_identifier:string
并运行rake db:migrate on:
and ran rake db:migrate on this:
class AddRpxToUsers < ActiveRecord::Migration
def change
add_column :users, :rpx_identifier, :string
end
end
如果有任何想法,请分享。我一直在努力解决这个问题。
If anyone has any thoughts, please share. I have been struggling with this issue all day.
非常感谢!
推荐答案
这可能是因为您可能已经在应用程序控制器中使用current_user方法。因此,设计不会看到它的current_user方法的实现,因此它的帮助方法总是返回false。只需删除或重命名您正在使用的current_user方法,并解决问题。
This might be because you might already be using the current_user method in the application controller. Due to that, the devise will not see its implementation of current_user method and hence it always returns false for its helper methods. Just remove or rename the current_user method which you are using and this solves the problem.
