Question

Devise不会重定向到after_sign_in_path_for提供的网址。它实际上调用了我的自定义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，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'

同样的结果。

我的自定义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，它会提供正确的网址，正如我预期的那样提供str。调试器此时停止...

但在cont页面保持sign_in之后，然而登录就会发生。

我认为这不是我的代码问题。这可能是一个设计问题。任何拥有工作的人都可以与我分享Devise的确切版本，它适合您。

很难说没有看到您的服务器日志。如果正在调用after_sign_in_path_for并生成预期的URL，则会留下一种可能性：

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

The respond_with method will act sensibly according to the status of the resource。由于它再次呈现new模板，因此它指向某种验证错误或其他问题登录。

查看服务器日志。以下是使用我的应用中的after_sign_in_path_for成功登录和后续重定向：

您是否看到了重定向？

设计after_sign_in_path_for有效，但重定向不会发生
