ruby on rails - SHA1 Encryption? -

-

I have the database with the following fields: id, q_id, text, session .. and I already have 2 records I want to encrypt each line (because every line is unique - id, session, course text ..) ..

@w = digest :: SHA1.hexdigest ( Id + q_id <+ Code +> instead it makes one. If that still is what you want to do, then my guess is that id and q_id are fixed and in string There is a need to convert. 

  @ wa = digest :: SHA 1. HexDogest (Answer: id.at_s + anacid.tts_s + anonymoustext + integration)   
 I also like to use the string because it makes it very clear that we are working with a string  
  @w = digest :: SHA1 .hexdigest ("# {id} # {q_id} # {text} # {session}}")

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)
