ruby on rails - Use array from model in form drop down -


रेल 4 पर रूबी

मेरे मॉडल में मेरे पास है: 

  @category_check = ['केबल्स', 'प्रिंटर', 'मॉनिटर', 'एक्सेसरीज', 'टॉवर्स', 'इंटरैक्शन']   
 इसका इस्तेमाल मान्य है, अब मैं चाहता हूं मेरे रूप में विकल्पों के रूप में सरणी प्रदर्शित करने के लिए यह काम नहीं करता है:  
  & lt;% = f.label: श्रेणी% & gt; & lt; br & gt; & Lt;% = f.collection_select: श्रेणी, @ श्रेणी_चेक, {प्रॉम्प्ट: "श्रेणी चुनें"}, वर्ग: "इनपुट-एलजी"% & gt;   
 क्या मुझे अपने नियंत्रक में एक और आवृत्ति चर बनाने की ज़रूरत है या मॉडल वेरिएबल से एक ड्रॉप डाउन में प्रत्येक प्रदर्शित करने का एक तरीका है? धन्यवाद   
 
 
 आपको इस तरह से कुछ कॉल करना है  
  & lt; % = F.collection_select: श्रेणी, @ श्रेणी_चेक,: to_s,: to_s, {प्रॉम्प्ट: "श्रेणी चुनें"}, वर्ग: "इनपुट-एलजी"% & gt;   
 यह @category_check संग्रह के प्रत्येक तत्व को to_s पास करेगा।
