覆蓋設計after_sign_in_path_for給出錯誤：過濾器鏈暫停爲：require_no_authentication呈現或重定向

Question

我覆蓋after_sign_in_path_for在我的ApplicationController中。

這裏的方法，使用Domainatrix解析的網址：

def after_sign_in_path_for(resource) 
     "#{resource.subdomain}." + host(request.url) + ":3000/profile" 
    end 

    def subdomain(url) 
    Domainatrix.parse(url).subdomain 
    end 

    def host(url) 
    Domainatrix.parse(url).host 
    end 

當我點擊「提交」一旦我的日誌：

    (1.3ms) commit transaction 
Redirected to trevor.lvh.me:3000/profile 
Completed 302 Found in 70ms (ActiveRecord: 2.0ms) 

這表明它重定向到正確的URL，但沒有發生任何事。

如果我點擊「提交」第二次，沒有任何反應和下面的日誌生成（注意2日至最後一行）：

    User Load (0.2ms) SELECT "users".* FROM "users" WHERE "users"."id" = 16 ORDER BY "users"."id" ASC LIMIT 1 
Redirected to trevor.lvh.me:3000/profile 
Filter chain halted as :require_no_authentication rendered or redirected 
Completed 302 Found in 2ms (ActiveRecord: 0.2ms) 

爲了進一步增加神祕感，當我改變after_sign_in_path_for到：

def after_sign_in_path_for(resource) 
    if resource.subdomain == subdomain(request.url) 
    "#{root_url}profile" 
    end 
end 

它正確地重定向到trevor.lvh.me:3000/profile。

任何想法這個Filter chain halted as :require_no_authentication rendered or redirected錯誤是什麼？

更換

def after_sign_in_path_for(resource) 
     "#{resource.subdomain}." + host(request.url) + ":3000/profile" 
    end 

隨着

def after_sign_in_path_for(resource) 
     "http://#{resource.subdomain}." + host(request.url) + ":3000/profile" 
end
