मेरे पास दो मॉडलों का पता मॉडल है 

  class address & lt; ActiveRecord :: बेस attr_accessible: address1,: address2,: देश,: काउंटी,: ग्राहक_आईडी,: शहर में संबंधित है: ग्राहक अंत   
 और एक ग्राहक मॉडल  
  कक्षा ग्राहक & lt; ActiveRecord :: बेस attr_accessible: ईमेल,: firstname,: lastname,: पासवर्ड,: फोन has_one: address end   
 मेरे पास सीआरयूडी कार्यक्षमता है जो मैंने एक स्कैफोल्ड का उपयोग करके उत्पन्न किया है। मैं क्या करने में सक्षम होना चाहता हूं, जब मैं एक नया ग्राहक जोड़ रहा हूं, तो मैं ग्राहक के लिए पते पर पते पर कोई पता चुन सकता हूं या कोई पता नहीं चुन सकता। मैं एक ग्राहक को देखने में सक्षम हूं और वहां उसका पता इस्तेमाल कर रहा हूं।  
  def showaddress @customer = customer.find (params [: id]) @address = @ ग्राहक.एडर उत्तर दें- do do format | Format.html # show.html.erb format.xml {रेंडर: xml = & gt; @ ग्राहक} एंड एंड   
 यह मेरा नया नियंत्रक है जो एक नया ग्राहक बनाने के लिए उपयोग किया जाता है  
  def new @customer = customer.new response_to do | format | Format.html # new.html.erb format.json {render json: @customer} एंड एंड   
 इसलिए मूल रूप से मैं क्या करना चाहता हूँ जब मैं एक नया ग्राहक बना रहा हूं, तो   
 
 
 आप शुरू कर सकते हैं पते की एक सूची ड्रॉप डाउन जो उपयोगकर्ता ग्राहक के साथ पते को संबद्ध करने के लिए क्लिक कर सकते हैं  नियंत्रक में  नया  पद्धति के सभी पतों का एक चर, और उस पृष्ठ को उस दृश्य बॉक्स में प्रपत्र में चयन बॉक्स को पॉप्यूलेट करने के लिए उपयोग करें।  
  def new @customer = ग्राहक.नवीन @एड्रेसस = एड्रेस एल ... ... अंत   
 या नीचे दिए गए रूपों में सीधे पते को भरना  
  select_tag 'address_id' , Options_for_select (Address.all.collect {| a | [a.name, a.id]})

excel vba - How to delete Solver(SOLVER.XLAM) code -

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'

I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job.
