Hi.
When I read Dave and Davids excellent book "Agile Web Development with
Rails" the first time, I was particularly impressed with the following
statement:
1.day.from_now
It was used in a test class to set the date of tomorrow dynamically. Since
it was enclosed in in ERb tags, I assumed this was a normal ruby statement,
but when I tried it in my irb, i get the following error:
irb(main):007:0> 1.day.from_now
NoMethodError: undefined method `day'' for 1:Fixnum
from (irb):7
irb(main):008:0>
I would be abliged if someone could explain to me how this works in ERb and
not in standard ruby? Have I missed something fundamental here?
Best regards,
J?rn ?lmheim

Indeed. You need to use script/console instead of a plain ruby shell.

Heh, in a thread last week about Rails driving development of Ruby, somebody asked how long it would be til someone mistook Rails'' core-extensions for Ruby :) Jeff Julian ''Julik'' Tarkhanov wrote:> On 31-mrt-2006, at 13:48, J?rn ?lmheim wrote: > >> the following error: >> irb(main):007:0> 1.day.from_now >> NoMethodError: undefined method `day'' for 1:Fixnum >> from (irb):7 >> irb(main):008:0> >> >> I would be abliged if someone could explain to me how this works in >> ERb and not in standard ruby?
