Hello,
I’m using Ruby 1.8.4 (darwinport), rails-1.0.0 (gem) , Powerbook / Mac
OS X 10.4.5 , Webrick.
How come Rails always raises NoMethodError for my helper (must_fill and
rp or number_to_currency_rp) in application_helper.rb ?
I doubt that alias_method is the culprit, but if i give #
comment then there will be no errors at all …
what am i doing wrong? is it a bug or stupid me? Thx
This is my helper:
module ApplicationHelper
alias_method :rp, :number_to_currency_rp
# Rp 1.907.000,00 instead of $1,907,000.00
def number_to_currency_rp(dolar)
number_to_currency(dolar, {:unit => "Rp ", :separator => ",",
:delimiter => “.”})
end
def must_fill(x)
‘’ + x + ‘’
end
end
From ri -f bs alias:
---------------------------------------------------- Module#alias_method
alias_method(new_name, old_name) => self
Makes _new_name_ a new copy of the method _old_name_. This can be
used to retain access to methods that are overridden.
module Mod
alias_method :orig_exit, :exit
def exit(code=0)
puts "Exiting with code #{code}"
orig_exit(code)
end
end
include Mod
exit(99)
_produces:_
Exiting with code 99
