I have a question about using local variables as values for ruby hashes. I have to do a script that will gather meta data of video files in a fixed directory and store them in an array of hashes. The problem is that when I have collected the meta data to a hash called video and append this to the end of videos array all the hash entries are the same in the array. I assign the values to the hash and append to the videos array with this script block:
video["res_w"] = res_w video["res_h"] = res_h video["dur_h"] = dur_h video["dur_m"] = dur_m video["dur_s"] = dur_s video["dur_ms"] = dur_ms videos << video All the local variables have been initialized as zeroes and when my loop retrieves another file for processing it reuses the local variables. The actual question is does the hash store a pointer to the local variable as its value? If it does is there a way to overwrite this behaviour or some way around it? -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
