ERb on he command line re: Ruby For Rails book

Hi,

I am working thru the Ruby for rails book. On page 30 David
Black
talks about running erb from the command line i.e. $ erb
erbdemo.rb
just as you would a normal ruby prog ($ ruby erbdemo.rb) but
when I
try to do this I get command not found. How do I make this
work? I am
running Linux (Ubuntu Breezy)

Regards,

Paul

It might depend how you installed Ruby.  Is it possible that
Ubuntu
bundles erb separately in a different package?

for what it's worth, I think Ezra Zyg. (he who does not
sleep) was
building a Rails-specific Ubuntu called Rubuntu.

David,

I am getting this when I attempt to run the code from CH 2
of your
book. Can you advise please?

Loading development environment.

I'm really not sure what could be behind that other than
for some
reason the application_controller.rb file being missing on
your
system, or maybe some kind of very obscure version mismatch
in the
Rails setup.  Is application_controller.rb there?


David

P.S. I'm in bond at the moment and not as constantly online
as I
usually am, but will be checking in at least periodically.

Hi David,

Thank you for your efforts. I am in Auckland, New Zealand so
we are a
180 deg out of sinc.

I sorted out the problem by starting the exercise again and
things
came right. So it was most likely finger problems.

On a new context, if you can spare a moment I need to
achieve the
following and I do not have much time to do it in
(Unfortunately I
have only just discovered your book and I am working from
the pdf
while I await the hard copy which I ordered on Friday).

I have two tables and they have a one to many relationship I
want to
display the contents in a browser. Parent with its children
beneath
it. How do I do this. I am a rails (and Ruby nuby, as you
already
know) so am pretty ignorant. Sorry to be making such a
nuisance of my
self.

Regards,

Paul
