Rails Replace Attributes in Arrays -

-

मेरे पास फिलीपींस में गलत शहरों का नाम है: 

  & gt; & gt; A = शहर.फंड_ऑल_बीकाउंटरी_आईडी (4) = & gt; [# & Lt; सिटी आईडी: 91, नाम: "अलामिओस", देश_आईडी: 4, बनाया गया_आट: "2009-11-12 04:06:14", अपडेटेड_ैट: "2009-11-12 04:06:14" & gt; , # & Lt; सिटी आईडी: 92, नाम: "एंजिल्स", देश_आईडी: 4, बनाया_ट: "2009-11-12 04:06:14", ...

और मैं सही नाम के साथ सभी नामों को बदलना चाहते हैं: 

  = & gt; बी = ["अबरा", "अगुसन डेल नॉर्ट", "अगुसन डेल सुर", ...

मैं प्रतिस्थापित पद्धति का उपयोग करना चाहता था क्योंकि मैं चाहता था मौजूदा शहर आईडी को अपडेट करने के लिए, यदि आवश्यक हो तो उन्हें डालें / छांट कर।

लेकिन मैं अभी भी इसे एक नहीं समझ सकता, क्योंकि a सरणियों का सरणी है (मुझे सही करें अगर मैं गलत हूं), जबकि b बस एक सरल, नीचे-से-पृथ्वी सरणी है।

एक शहर के मॉडल की एक सरणी होना चाहिए। उदाहरण के लिए यदि आप "आभा" (अरैम में पहला तत्व) को शहर के आईडी 9 1 (पहला रिकॉर्ड) के शहर का नाम बदलना चाहते थे, तो आप केवल a [0] .name = b [0] । मैं बिल्कुल नहीं जानता कि वास्तव में आप क्या करने की कोशिश कर रहे हैं, लेकिन उम्मीद है कि यह आपको समस्या का वाक्य-रचनात्मक भाग देगा।

c# - How to capture HTTP packet with SharpPcap -

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes. All st...

By using Wordpress I have created a multiple selection box so that users can select categories to exclude. When the page is initially loaded, I see my predefined default option. However, when I select a new value and I save ...

jquery - SimpleModal Confirm fails to submit form -

-
I am trying to confirm jQuery to show yes / no confirmation when I submit a form. I had modified (in the last list) to capture and block form submissions. However, it only works with jQuery 1.2.6, a recent upgrade stops 1.3.2, if yes is clicked, then by submitting the form. But I can not understand what is wrong / inconsistent in my code now. Demo (which works in both versions of a simple window.href implementation). $ (document) .ready (function () {$ ('input.delete'). Click (function (e) {e.preventDefault (); var target = $ (e .target); Confirm ("Really delete this event?", Function () {target.click ()});});}); How about something like this? The idea of ​​catching clicks (and fire!) On the submitted event is not click event. $ (document) .ready (function () {$ ('# myForm'). Submit (function () {var f = this; Confirm (" Remove? ", Function () {$ (f). Submit ();}) Return; Return the initial session;}}}}; Hope That this is som...
