arrays - Kohana 3 arr::rotate -

-

I am trying to upload a multipatt file in Coha 3. I do not know the number of files that will be uploaded. I have tried this UISER: Rocket, but it is not visible to any method of Koha 3. ($ _ Files ['product_image']) $ as file $ {Variable = Upload :: Save ($ _ files ['product_image'], 

  foreach (arr :: rotate ($ _ FILES ['product_image' Tap, applepath. 'Media'. '/'); $ Product_image- & gt; Image = bassname ($ variable); }   
 How do I do arr :: rotate in 3?   
 
 
 For now, you can copy the method from the Kohana 2 codebase to an extended AR class. We will add it to Kohana 3.2.

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)
