Well, I'm pretty confused... Defining my method as an instance method
didn't seem to work when I tried it. I checked it again this morning and...
boum, it's working. Really doesn't have a clue why it didn't work at first
and works today, I must have missed something last time.
Anyway thanks a lot for your answer, and sorry for this dumb question.
Cheers

what you're doing there is defining a class method named more_than_fifty?
a method declared like that can be called from the class itself, not an
instance of it.
So, you end up with:
Day.more_than_fifty?
instead of:
day = Day.new
day.more_tan_fifty?
to add instance methods to a class, just declare them like this:
def method_name
# do something
end
that is, without using self

Hey guys,
I'm beginning with Sinatra and using DataMapper as my ORM tool of choice.
I've been doing great, playing with this today, but I'm now stuck. I'd like
to add a custom method to one of my models, that would check some values of
an instance, make some comparisons and return a boolean.
I tried the following :
class Day
include DataMapper::Resource
property :id, Serial
property :day_number, Integer
property :status, Integer, :default = 0
property :date, Date
*
def self.more_than_fifty?
# Just for the sake of the example
rand(1..100) 50
end*
end
But didn't work. I've seen one or two cryptic messages on Stack Overflow
about DataMapper::Model.append_inclusions, but not enough for me to
understand and get it working.
Anyone who could help me around here ? Thanks a lot for your time guys.
Paddy
