设计after_sign_in_path_for有效,但重定向不会发生

Question

设计不会重定向到提供的网址after_sign_in_path_for.它实际上调用我的自定义after_sign_in_path_for.它会计算我希望它计算的url,但之后不会发生重定向.它保留在sign_in页面上,但实际登录不会发生.

我一直在尝试几个版本的设计:

gem 'devise'

和

gem 'devise', :git => 'git://github.com/plataformatec/devise.git'

结果相同.

我的习惯 after_sign_in_path_for

def after_sign_in_path_for(resource)
    str = stored_location_for(resource) || stored_location || root_path
    debugger
    str
end

def stored_location
    session.delete(:return_to)
end

def store_location
    session[:return_to] = request.fullpath
end

正在被调用,它提供了正确的URL,str完全按照我的预期给出.调试器此时停止...

但是在cont页面停留之后sign_in,然而登录仍在进行.

我相信这不是我的代码问题.这可能是一个设计问题.能有它工作的任何人都可以与我分享Devise的确切版本,它与你合作.

如果没有看到您的服务器日志，很难说。如果after_sign_in_path_for被调用并生成预期的 URL，则留下一种可能性：

\n\n

# app/controllers/devise/sessions_controller.rb\n# POST /resource/sign_in\ndef create\n  resource = warden.authenticate!(auth_options)\n  set_flash_message(:notice, :signed_in) if is_navigational_format?\n  sign_in(resource_name, resource)\n  respond_with resource, :location => after_sign_in_path_for(resource)\nend\n

\n\n

该respond_with方法将根据资源的状态明智地采取行动。由于它new再次渲染模板，因此它表明存在某种验证错误或其他登录问题。

查看服务器日志。这是使用我的应用程序成功登录和随后的重定向after_sign_in_path_for：
