ruby - Grabbing returned variables? -

-

lets have model called lead , controller method called functions. lead model has method called grab.

def functions     lead.grab(data)     puts newdata end  def grab(data)     newdata = data + 20     return newdata end

why not work? newdata variable passed functions method cannot seem use without undefined error.

you should have newdata = lead.grab(data). variable newdata in grab function out of scope of controller, can't use it. have set variable in controller returned value of lead.grab(data).

mysql - FireDac error 314 - but DLLs are in program directory -

i getting when trying access mysql database : [firedac][phys][mysql]-314. cannot load vendor library [libmysql.dll or libmysqlld.dll] this did not happen (unchanged) code, however, have upgraded windows 10 , had reinstall delphi xe8, system configuration matter. in order try solve problem, copied both of files c:\windows\sysytem32. when did not seem work, copied them \win32\debug, generated .exe resides. i imagine doing rather stupid, can't see what. the proper solution place driver file (eg., libmysql.dll ) in application's folder, or place installation location in fddrivers.ini file: [mysql] vendor=<folder>\libmysql.dll (recent versions of documentation seem use vendorlib instead of vendor in ini file.) see rad studio documentation topics configuring drivers (firedac) , connect mysql server (firedac) more information.
