ruby on rails - How do I submit and save a Child form with the Parent as nested fields? -

-

मान लें कि आपके पास निम्न बाल वर्ग है: 

  बच्चे & LT; एआर संबंधित_तो: मूल समाप्ति   
 जो  जनक  वर्ग से संबंधित है:  
  माता-पिता & lt; एआर has_many: बच्चों का अंत   
 मैं एक  ChildrenController  की एक कार्रवाई / दृश्य के भीतर एक फ़ॉर्म बनाना चाहूंगा जो उपयोगकर्ता को एक नया  बच्चे  और एक नया  माता-पिता  अगर कोई भी नहीं नियुक्त किया गया है (मैं एक  माता-पिता नियंत्रक  नहीं चाहता है क्योंकि उसके पास आवेदन की समान प्रासंगिकता नहीं है )।  
 मैंने new.haml.html दृश्य में एक सरल रूप बनाया है:  
  = simple_form @child do | c | C.input: field_for_child c.association: माता पिता के | पी | P.input: field_for_parent   
 नतीजा एक पैरामैश हैश है जो  "child" = & gt; {"Field_for_child" = & gt; "मान 1", "अभिभावक" = & gt; {"Field_for_parent: = & gt;" value2 "}}   
" बाल "और" माता-पिता "को जितनी संभव हो उतनी कम लाइनों में सहेजने के लिए मैं क्या कर सकता हूं?   
 
 
  @ child.parent_id = (पराम [[अभिभावक] [: field_for_parent])) parent.create (... ) .id   
 यह मेरा शिक्षित अनुमान होगा ... कहां "(...)" नए माता पिता के लिए आपका तर्क होगा

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.

What is a Python equivalent for Ruby's define_method , which is the dynamic generation of class methods will allow? (As can be seen in Wikipedia) Functions are first-class objects in Python and assign them The properties of a class or an example can be a way of doing the same thing as a Wikipedia example: colors = {"black": "000", "red": "F00", "green": "0f0", "yellow": "ff0", "blue": "00f", "magenta": "fff", "cyan": "0ff", "white": " FFF "} Class MyStream (ARR): Pass for Name, Code in colors.iteritems (): def _in_colour ( W code = code): return '& lt; Span style = "color:% s" & gt;% s & lt; / Span & gt; ' % (Code, self) setter (histrive, "in_" + name, _in_ color)
