Ruby on Rails
Tuesday, June 1, 2010
you could create a method called
def leading_zeros(number)
"%05d" % number
end
and then call it
"#{leading_zeros order.id}#{order.name}"
What you have with ""#{order.id}".leading_zeros
is that #{order.id} will evaluate to a string and then you are trying to call the leading_zeros method on the string. For it to work as you intend leading_zeros needs to be part of the String class.
There is no end of pain in doing this.
Just save leading_zeros as a helper method in the application helps and call it as I have shown.
