  Amazingly, if I change the file name to date_extensions.rb it works. Odd.

  Could you please put this in the top of the file and paste the extra line it prints? (should begin with "LOAD PATH: ")

  puts "LOAD PATH: #{$LOAD_PATH.inspect}"
  

  I think that since this file would be before the ruby core date.rb, it requires your file instead or something.

  Not the easiest thing to paste, but here it is:

  @Henrik I would rather ask $LOADED_FEATURES or $"

  Could you please add this in the top of your file and paste the result between BEGIN and END ?

  puts "BEGIN"; puts $"; puts "END"

  • Tag changed from “3.0.0, date, ruby-1.9.2” to “load path, 3.0.0, date, ruby-1.9.2”

  @Benoit Oops, yes. Dunno why I asked for the load path.

  Anyways, Avand, I've done some testing and if there's a file in your load path called date.rb, Ruby will load that instead of it's internal one for Date for some odd reason. So I would suggest renaming it to something else (like date_extensions.rb).

  @Henrik Eventually, both are be useful :)

  The reason is simple: the lib/ folder is before the stdlib in $LOAD_PATH (lib is 2nd, stdlib is 71st).

  The source of the problem is then the lib/ folder to be #unshift to $LOAD_PATH.
  Do you know why Rails do this?

  This let you override the stdlib libraries, but also prevent you for ever loading them, which does not seems right (except if those were loaded before $: was changed, which should be the case as AS use Date, but this might be a problem of #autoload).

  If stdlib was before, you would be forced to load your file with an absolute path, which I think make sense when you use a file with the same name.

  @Avand: Rather than renaming it, I would put it in a subfolder of lib/, like "extensions", and so do a

  require 'extensions/date'
  

  which seems explicit and avoid conflicts.

  Either of those solutions will work for my purposes. Thanks @Henrik and @Benoit.

  At a higher level though, it would seem that what I did first, shouldn't have bombed like it did - I would have expected it to just work and re-open the class as defined by Rails.

  • State changed from “new” to “resolved”
  • Importance changed from “” to “Low”

  When you call a file "date" and place it in the lib directory and attempt to require the ruby +'date'+, you'll get this one instead. It may not be you who's requiring it, but still: best practice is to NOT call your files with the same name as what they are extending.

  An _ext.rb extension or the extensions directory like Benoit suggested are the best practices.
