Re: [DataMapper] Adding custom methods to a model ?

2013-03-11 Thread Pierre-Adrien Buisson
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.
