Reading contents of a file and storing
343566 [idealone5@ho] Guys,

Load & Execute Code From a Database
343577 [paulf@a2 li ] Sometime ago there was a discussion  about loading & running code held
343622 [karottenreib] I guess you could sandbox it? There are Ruby sandboxes out there...
343627 [b.candler@po] _why's sandbox looks to be pretty good, but it requires you to rebuild
343629 [paulf@a2 li ] My question is a little more basic (and dumb)
343631 [b.candler@po] str = "puts 'ha ha ha'"
343632 [paulf@a2 li ] Thanks, Brian,
343633 [b.candler@po] load("file.rb") is pretty much the same as eval(File.read("file.rb"))
343634 [b.candler@po] ... and incidentally, there are several examples of programs which load

Destroying related objects doubt ... basic oop question

  |   343799 [rubfor@re it] My point was ORMs mean you have to struggle understanding a new

instance_variables vs. local_variables
343596 [rubyforum@sp] Can anyone offer a reasonable explanation for the difference in behavior
343597 [vjoel@pa h. ] That's exactly right, IIRC.
343598 [rubyforum@sp] So the implication here is that there is no way to define a local

  + 343608 [rubyforum@sp] This clears up a misperception I had when trying similar examples.  For
  | 343624 [b.candler@po] As far as I understand, it's not exactly a "copy". Rather, each binding
