javascript - Rails fields_for enumerate with id -

-

अगर मेरे पास एक मानक fields_for विधि है: 

  & Lt;% = f.fields_for: exptypes do | बिल्डर | & Gt%; & Lt;% = रेंडर 'एक्सटिप्ट_फल्ड्स',: f = & gt; बिल्डर% & gt; & Lt;% end% & gt;

क्या ऐसा कोई तरीका है: 

  & lt;% = f.fields_for: exptypes do | बिल्डर, i | & Gt%; & Lt;% = रेंडर 'एक्सटिप्ट_फल्ड्स',: f = & gt; बिल्डर,: i = & gt; आई% & gt; & Lt;% end% & gt;

ताकि किसी अनन्य संख्या ( i ) को फ़ॉर्म में भेज दिया जाए?

मैं क्या करना चाहता हूँ, आंशिक में अद्वितीय div टैग बना लेता है, इसलिए मैं कोड में विशिष्ट आंशिक पर जावास्क्रिप्ट चला सकता हूं।

< Div class = "post-text" itemprop = "text">

आप भाग्य में हैं - रेल यह पहले से ही करता है, स्वचालित रूप से 3.4.6 से नीचे स्थानीय चर

रेल भी एक आंशिक संग्रह के तहत एक काउंटर चर उपलब्ध बना देता है, संग्रह के सदस्य के नाम पर _counter द्वारा पीछा किया गया। उदाहरण के लिए, यदि आप @ उत्पादों का अनुवाद कर रहे हैं, तो आंशिक के भीतर आप यह बता सकते हैं कि आंशिक रूप से कितनी बार प्रस्तुत किया गया है। यह:: value विकल्प के साथ संयोजन के रूप में काम नहीं करता है।

आपके मामले में, यह शायद exptype_fields_counter होने वाला है।

How to access user directory in lazarus? -

After I am trying to open file changelog.txt and it does not matter if I open it Need to have the user open it though it is always located in the ~ / directory. Enter the file here. Here is my code: Process TForm1.FormCreate (From: TObject); Var myFile: textfile; Line: String; Start AssignFile (myFile, '~ / changelog.txt'); Reset (myFile); While EOF (MyFile) does not readLn (myFile, Line); Label3.Caption: = (Label3.Capttion + Line + # 13 # 10); End; CloseFile (myFile); End; This does not work, however, if I replace ~ with the actual user name, then it works, however, I use the username of each user Can not know which will run my program. Any idea how can I get the username that started the program? ! Thanks Edit1: I have tried this, but this also includes a new line: RunCommand ('/ bin / bash', ['- - C ',' Whoami '], users); This is normal. The concept of "~" is an shell level and thus requires a separate shell elev...
