Rails – select current menu item -

-

मैंने एक छोटा सहायक बनाया है जो class = "selected" जोड़ता है। वर्तमान पथ वर्तमान मेनू आइटम है, और यह चयन करने के लिए प्राथमिक रूप से यह current_page? का उपयोग करता है। 

  मॉड्यूल मेनूहेलर #renders मेनू आइटम और वर्तमान मेनू आइटम पर जोर देती है डेफ टॉपमेनू पेज = {"प्रॉडक्ट्स" = & gt; Admin_products_path, "श्रेणियां" = & gt; Admin_categories_path, "कैटलॉग" = & gt; Admin_catalogs_path, "बिक्री चैनल" = & gt; Admin_sales_channels_path} pages.map करें | कुंजी, मान | यदि मौजूदा_पृष्ठ (मूल्य) "& lt; li # {classnames} & gt; # {link_to (कुंजी, मान)} & lt; / li & gt; classnames =% (class =" current ") एंड एंड / लेआउट्स / एप्लिकेशन। Html:  
  & lt; ul class = "topmenu" & gt; & Lt;% = टॉपमेनयू% & gt; & Lt; / ul & gt;  
 
 मेरे दृष्टिकोण में एक बड़ा दोष है  / एडमिन / कैटलॉग  का चयन एक जादू की तरह काम करता है लेकिन किसी भी उप-पृष्ठ ( / admin / catalogs / 1 , आदि नहीं) 
 
 मुझे लगता है कि विधि के तरीकों से मेरा दृष्टिकोण दोषपूर्ण हो सकता है 
 
 क्या आपके पास इस तरह के यूआरएल को स्वीकार करने के लिए इस स्क्रिप्ट को बढ़ाने के बारे में कोई विचार है, या क्या इसे हासिल करने का एक चालाक तरीका है?

जिस प्रकार मैंने एक समान मेनू सहायक बनाया था, वह नियंत्रक_नाव और action_name विशेषताओं को देखना था और फिर तय किया गया था कि कोई दिए गए पृष्ठ चयनित / सक्रिय है या नहीं या नहीं। यह पूर्ण यूआरएल से कम विशिष्ट है, इसलिए यह उपयोगी हो सकता है। 

  search_page_active = नियंत्रक.controller_name == 'छात्र' & amp; amp; \ Controller.action_name == 'खोज'

.net - C# List<T>.Find(x=>x.Rectangle.Contains(Point)) FAIL -

-
For my life, I can not understand why this code generates the following output ... I think there is a bug or something while using the list and lambda, if type one rectangle exposes the property and you use the included method of rectangle object ... and the clear statement proves true while Find list method fails .... Onway Code Public Gridskeyr Warldtokapadsb (Point location) {location = _Map.WorldToClient (location); Gridsquare gs = this.find (x => x.Rectangle.Contains (location)); GridSquare KP = G.Find (X => X. laxative canteen (location)); & Lt; GridSquare & gt; List = kp.FindAll (x => x.Rectangle.Contains (location)); U.dp (list.Count); Gridskare sub = KP.Fid (X => X. laxative canteen (location)); If (sub == faucet) {u.dp (place to look for "location"); U.dp ("The location found in the grid category" + GS toaster ()); U.dp ("Grid Square Bounds" + gs.Rectangle.ToString ()); U.dp ("location found in keypad" +...

objective c - iPhone and it's wireless area -

-
Is this a way to find other iPhones in the category of wireless areas? So I give an example. I'm staying at the airport somewhere I have an iPhone too. I and the other iPhone owners are playing the same game. Is there any way to warn me and the other player that we are close to each other? Does this work even if we are not on the same wireless network, or there is no wireless? And if there is any way to do this, can you give me some starting point? Like a link where I can learn something like this or maybe this is probably the name of this process, because I do not know how to search about this topic in Google. Thanks in advance! Can be completed with peer-to-peer discovery and connectivity you are describing Game Kit Framework Originally I thought it works only through Bluetooth, but after watching it immediately, it seems that WiFi is also supported. Hope it helps!
